NEW QUESTION # 20
An administrator is asked toimprove the capacity of an Events Service cluster. What is the recommended way to add capacity to the cluster?

• A. Add a new Events Service cluster to share the load.
• B. Add nodes running on machines with identical hardware matching the existing nodes.
• C. Add more storage to as many of the existing nodes as possible.
• D. Add more storage to the master nodes of the cluster.

Answer: B

Explanation:
Explanation
According to the Cisco AppDynamics Professional Implementer (CAPI) documents, the recommended way to add capacity to the Events Service cluster is to add nodes running on machines with identical hardware matching the existing nodes12. This will increase the data storage, replication, and redundancy of the cluster, as well as the processing power for queries. The Events Service cluster is horizontally scalable, so nodes can be added as your data storage requirements grow32. The Events Service must run on dedicated machines with identical directory structures, user account profiles, and hardware profiles1. For heap space allocation, AppDynamics recommends allocating half of the available RAM to the Events Service process, with a minimum of 7 GB up to 31 GB1. Solid-state drives (SSD) can significantly outperform hard disk drives (HDD), and are therefore recommended for production deployments1.
The incorrect options are:
Add a new Events Service cluster to share the load. (A) This is not recommended because it will create additional complexity and overhead for managing multiple clusters and routing data and queries to the appropriate cluster. It will also require more license units to enable analytics on multiple clusters.
Add more storage to the master nodes of the cluster. This is not recommended because it will not increase the data replication and redundancy of the cluster, nor the processing power for queries. It will also create an imbalance in the cluster, as the master nodes will have more storage than the worker nodes, which may affect the performance and stability of the cluster.
Add more storage to as many of the existing nodes as possible. (D) This is not recommended because it will not increase the data replication and redundancy of the cluster, nor the processing power for queries. It will also create an imbalance in the cluster, as some nodes will have more storage than others, which may affect the performance and stability of the cluster.

NEW QUESTION # 21
Instead of using the Enterprise Console Ul, how can an administrator import an existing keypair to manage the Controller SSL certificate?

• A. Re-run the Controller installer and specify the new keypair.
• B. Upload a new keystore.jks file through the Controller Ul.
• C. Add the keypair to the keystore.jks using a third-party tool.
• D. Upload the keypair from within the Controller UL.

Answer: C

Explanation:
Explanation
According to the Cisco AppDynamics Professional Implementer (CAPI) documents, the method to import an existing keypair to manage the Controller SSL certificate without using the Enterprise Console UI is to add the keypair to the keystore.jks using a third-party tool (A). The keystore.jks file is the default keystore for the Controller that contains the private keys and certificates for the secure communication on port 8181. If the administrator already has a custom keypair that is signed by a third-party Certificate Authority (CA) or an internal CA, they can use a third-party tool, such as KeyStore Explorer or OpenSSL, to import the keypair into the keystore.jks file. The administrator should also import the root or intermediate certificates of the CA into the cacerts.jks file, which is the default truststore for the Controller. The administrator should use the keytool utility, which is bundled with the Controller installation, to import the certificates into the cacerts.jks file. The administrator should also update the password for the keystore.jks and cacerts.jks files, and restart the Controller to apply the changes12.
The incorrect options are:
Re-run the Controller installer and specify the new keypair. (B) This is not a valid method because the Controller installer does not allow the administrator to specify a custom keypair for the Controller SSL certificate. The Controller installer only allows the administrator to specify the Controller host name, port, account name, access key, and database settings. The Controller installer does not modify the keystore.jks or cacerts.jks files, and does not import any custom keypair or certificate into the Controller keystore or truststore3.
Upload a new keystore.jks file through the Controller UI. This is not a valid method because the Controller UI does not provide any feature to upload a new keystore.jks file for the Controller SSL certificate. The Controller UI only allows the administrator to view and edit the Controller settings, such as the license, the security, the email, the analytics, and the EUM. The Controller UI does not access or modify the keystore.jks or cacerts.jks files, and does not import any custom keypair or certificate into the Controller keystore or truststore4.
Upload the keypair from within the Controller UI. (D) This is not a valid method because the Controller UI does not provide any feature to upload a custom keypair for the Controller SSL certificate. The Controller UI only allows the administrator to view and edit the Controller settings, such as the license, the security, the email, the analytics, and the EUM. The Controller UI does not access or modify the keystore.jks or cacerts.jks files, and does not import any custom keypair or certificate into the Controller keystore or truststore4.

NEW QUESTION # 22
Which data is unavailable in a hybrid deployment of AppDynamics where the AppDynamics Controller and Events Service are installed on-premises and the EUM Server is hosted inAppDynamics' SaaS cloud?

• A. End-User Monitoring resource loading times
• B. End-User Monitoring session information
• C. End-User Monitoring browser snapshots
• D. Analytics metrics for End-User Monitoring data sets

Answer: D

Explanation:
Explanation
In a hybrid deployment of AppDynamics, where the AppDynamics Controller and Events Service are installed on-premises and the EUM Server is hosted in AppDynamics' SaaS cloud, the data that is unavailable is the analytics metrics for End-User Monitoring data sets. This is because the analytics metrics require the Events Service to store and process the unstructured data generated by the EUM agents. However, in a hybrid deployment, the EUM Server and the Events Service are not connected, and the EUM Server does not send the EUM data to the Events Service. Therefore, the analytics metrics for EUM data sets, such as browser records, mobile snapshots, network requests, and custom events, are not available in the Controller UI or the Analytics UI1. The other data, such as resource loading times, session information, and browser snapshots, are available in the EUM Server UI, as they are stored and displayed by the EUM Server itself2. References: Hybrid Deployment and EUM Data Sets in the AppDynamics documentation.

NEW QUESTION # 23
What is required in order for an upgrade of the Java Agent to succeed?

• A. The AppDynamics Controller must be restarted.
• B. The application JVM must be restarted after the agent had been updated.
• C. The host machine must be restarted.
• D. The Machine Agent must be upgraded first,

Answer: B

Explanation:
Explanation
To upgrade the AppDynamics Java Agent, you need to copy the existing agent directory to a backup location and replace it with the new agent directory. You also need to copy any configuration file changes made in the old directory to the new agent directory. After that, you need to restart the application JVM where the Java Agent is installed, so that the new agent can take effect. Restarting the application JVM is the only required step for the upgrade to succeed. You do not need to restart the host machine, the Machine Agent, or the AppDynamics Controller12. References: Upgrade the Java Agent, Release Upgrade Checklist for Java Agents

NEW QUESTION # 24
What are two capabilities of the standalone Machine Agent running on Linux? (Choose two.)

• A. lt can send SNMP alerts.
• B. It can restart itself if it goes down.
• C. It can act as a forwarder for analytics events.
• D. It can start an HTTP listener for custom metrics.
• E. It can communicate with multiple AppDynamics Controllers.

Answer: C,D

Explanation:
Explanation
The AppDynamics standalone Machine Agent is a Java program that runs on a host machine and collects hardware and infrastructure metrics, such as CPU, memory, disk, and network usage. The Machine Agent can also perform additional functions, such as:
Acting as a forwarder for analytics events: The Machine Agent can be configured to forward business transaction, log, browser, mobile, and synthetic events from the application agents to the AppDynamics Events Service, which is a distributed, scalable data store for analytics data. The Machine Agent can also forward custom events from the SDK or API to the Events Service. This allows you to use the AppDynamics Analytics features, such as dashboards, queries, funnels, and metrics, to analyze the performance and behavior of your applications and users12.
Starting an HTTP listener for custom metrics: The Machine Agent can be configured to start an HTTP listener that can receive custom metrics from external sources, such as scripts, tools, or other applications. The Machine Agent can then report these custom metrics to the AppDynamics Controller, where youcan view them in the Metric Browser or use them in health rules, policies, or dashboards. This allows you to monitor any aspect of your system that is not covered by the default Machine Agent metrics34.
The other statements are false because:
B: The Machine Agent cannot send SNMP alerts. The Machine Agent can only receive SNMP traps from external sources and report them as events to the AppDynamics Controller. The AppDynamics Controller can send SNMP alerts to external systems based on health rule violations or events, but this is not a function of the Machine Agent5 .
C: The Machine Agent cannot communicate with multiple AppDynamics Controllers. The Machine Agent can only communicate with one Controller at a time, which is specified in the controller-info.xml file in the agent configuration directory. If you want to monitor the same host machine with multiple Controllers, you need to install multiple Machine Agents on the same machine, each with a different Controller configuration and port number .
D: The Machine Agent cannot restart itself if it goes down. The Machine Agent does not have a built-in mechanism to automatically restart itself in case of a failure or a crash. You need to use an external tool or script to monitor the Machine Agent process and restart it if necessary. Alternatively, you can use the AppDynamics Agent Installer to deploy the Machine Agent as a service, which can be configured to restart automatically on failure .

NEW QUESTION # 25
What are two reasons that would require an administrator to install the Events Service cluster manually?
(Choose two.)

• A. Security concerns with passwordless SSH
• B. Security requirements to install using a non-root user account
• C. Installation on SUSE Linux
• D. Installation on Windows

Answer: A,B

Explanation:
Explanation
According to the Cisco AppDynamics Professional Implementer (CAPI) documents, the two reasons that would require an administrator to install the Events Service cluster manually are:
Security concerns with passwordless SSH (B): This is a valid reason because the automated installation of the Events Service cluster requires passwordless SSH access to the target hosts. Passwordless SSH allows the Enterprise Console to execute commands on the remote hosts without prompting for a password. However, some organizations may have security policies that prohibit passwordless SSH access, as it may pose a risk of unauthorized access or malicious attacks. In such cases, the administrator can install the Events Service cluster manually, by following the steps described in the Manual Installation of the Events Service Cluster document1.
Security requirements to install using a non-root user account : This is a valid reason because the automated installation of the Events Service cluster requires root privileges on the target hosts. Root privileges allow the Enterprise Console to create directories, change permissions, and install packages on the remote hosts. However, some organizations may have security policies that restrict root access, as it may pose a risk of accidental or intentional damage to the system. In such cases, the administrator can install the Events Service cluster manually, by following the steps described in the Manual Installation of the Events Service Cluster document1. The administrator can use a non-root user account that has sudo privileges to perform the manual installation.
The incorrect options are:
Installation on SUSE Linux (A): This is not a valid reason for manual installation, because the automated installation of the Events Service cluster supports SUSE Linux as one of the compatible operating systems. The Enterprise Console can install the Events Service cluster on SUSE Linux hosts using the automated installation process, as long as the hosts meet the prerequisites described in the Events Service Requirements document2.
Installation on Windows (D): This is not a valid reason for manual installation, because the Events Service cluster does not support Windows as an operating system. The Events Service cluster can only run on Linux hosts, as it is based on Apache Cassandra, which is a Linux-based distributed database. The Events Service cluster cannot be installed on Windows hosts, either manually or automatically2.

NEW QUESTION # 26
What are two valid reasons for using the REST API to retrieve health rule violations? (Choose two.)

• A. For determining which actions have been executed
• B. For sending emails
• C. When searching for historical events
• D. For updating an AppDynamics dashboard
• E. When pushing events to the Event Management System is NOT possible

Answer: A,C

Explanation:
Explanation
According to the Cisco AppDynamics Professional Implementer (CAPI) documents, the REST API for health rule violations allows you to retrieve information about the health rule violations that occurred in a specified time range for a given application1. You can use the REST API for health rule violations for the following valid reasons:
For determining which actions have been executed (B): The REST API response includes the details of the actions that were triggered by the health rule violation, such as email, SMS, HTTP request, or custom action1. You can use this information to verify if the actions were executed successfully, or to troubleshoot any issues with the action execution.
When searching for historical events : The REST API allows you to specify a custom time range for retrieving the health rule violations, such as BEFORE_TIME, AFTER_TIME, BETWEEN_TIMES, or BEFORE_NOW1. You can use this feature to search for historical events that occurred in the past, or to analyze the trends and patterns of the health rule violations over time.
The incorrect options are:
For updating an AppDynamics dashboard (A): This is not a valid reason for using the REST API for health rule violations, because the AppDynamics dashboards already display the health rule violations that occurred in the selected time frame, along with the severity, status, affected entities, and actions2.
You do not need to use the REST API to update the dashboard, as the dashboard is automatically refreshed with the latest data from the Controller.
For sending emails (D): This is not a valid reason for using the REST API for health rule violations, because the REST API does not send emails directly. The REST API only returns the information about the health rule violations, and the actions that were triggered by them. If you want to send emails based on the health rule violations, you need to configure an email action in the health rule configuration, or use a custom action that invokes an external email service3.
When pushing events to the Event Management System is NOT possible (E): This is not a valid reason for using the REST API for health rule violations, because the REST API does not push events to the Event Management System. The REST API only returns the information about the health rule violations, and the actions that were triggered by them. If you want to push events to the Event Management System, you need to configure an HTTP request action in the health rule configuration, or use a custom action that invokes an external API3.

NEW QUESTION # 27
Which type of Alert and Respond action is available only on an on-premises Controller?

• A. Cloud auto-scaling
• B. Remediation action
• C. Diagnostic action
• D. Custom action

Answer: D

Explanation:
Explanation
A custom action is a type of Alert and Respond action that allows you to integrate AppDynamics notifications with your own alerting or ticketing system. You can create a custom action by writing an executable script and an XML file that describe how to pass information from AppDynamics to your system. A custom action can be triggered by a policy based on a health rule violation or an event. A custom action is available only on an on-premises Controller, because it requires access to the Controller file system and the ability to execute scripts on the Controller host machine. For a SaaS Controller, you can use HTTP request templates instead of custom actions to integrate with external systems. References: Build a Custom Action, Alert and Respond, Actions, Custom Actions

NEW QUESTION # 28
The application server was restarted after an upgrade. What are two valid ways to confirm that the upgraded Java Agent is running successfully? (Choose two.)

• A. Verify the Java Agent Version metric for that node in the Metric Browser.
• B. Verify that the application log contains a message indicating success.
• C. Verify that the node within the Controller Ul indicates the app agent is reporting.
• D. Verify that the Java Agent log contains a message indicating the agent started successfully.

Answer: A,C

Explanation:
Explanation
According to the Cisco AppDynamics Professional Implementer (CAPI) documents, the two valid ways to confirm that the upgraded Java Agent is running successfully are:
Verify that the node within the Controller UI indicates the app agent is reporting. (B) This is a valid way because the Controller UI is a web-based application that allows users to monitor and manage the performance of the applications, tiers, nodes, and other entities that are instrumented by the AppDynamics agents. The Controller UI displays the status of the nodes within each tier, and indicates whether the app agent is reporting or not. If the app agent is reporting, the node icon is green and shows the agent version. If the app agent is not reporting, the node icon is gray and shows the last time the agent reported. The user can also hover over the node icon to see more details, such as the agent type, the agent version,the agent runtime directory, and the agent properties file. The user can verify that the upgraded Java Agent is running successfully by checking that the node icon is green and shows the latest agent version12.
Verify the Java Agent Version metric for that node in the Metric Browser. This is a valid way because the Metric Browser is a feature of the Controller UI that allows users to view and analyze the metrics collected by the AppDynamics agents. The Metric Browser displays the metrics in a hierarchical tree structure, where each node represents a metric category, a metric name, or a metric value. The user can expand or collapse the nodes, and select or deselect the metrics to view them in a chart. The user can also apply filters, time ranges, baselines, and other options to customize the chart. The user can verify that the upgraded Java Agent is running successfully by navigating to the Java Agent Version metric for that node in the Metric Browser. The Java Agent Version metric shows the version number of the Java Agent that is running on the node. The user can compare the metric value with the expected agent version, and check that the metric is updated after the upgrade34.
The incorrect options are:
Verify that the application log contains a message indicating success. (A) This is not a valid way because the application log does not contain any message indicating the success of the Java Agent upgrade. The application log is a file that records the events and messages that occur in the application server, such as the startup, shutdown, errors, warnings, and debug information. The application log does not record the events and messages that occur in the Java Agent, such as the installation, upgrade, configuration, or reporting. The Java Agent has its own log file, which is located in the
<agent_home>/logs directory, and which contains the messages indicating the success or failure of the Java Agent upgrade .
Verify that the Java Agent log contains a message indicating the agent started successfully. (D) This is not a valid way because the Java Agent log does not contain any message indicating the agent started successfully after the upgrade. The Java Agent log is a file that records the events and messages that occur in the Java Agent, such as the installation, upgrade, configuration, or reporting. The Java Agent log contains a message indicating the agent started successfully when the application server is started, not when the Java Agent is upgraded. The Java Agent log does not contain any message indicating the success or failure of the Java Agent upgrade. The Java Agent log is located in the <agent_home>/logs directory, and the message indicating the agent started successfully is "Agent Startup Complete" .

NEW QUESTION # 29
Which two statements are true about instrumenting standalone Windows services with NET Agent? (Choose two.)

• A. AppDynamics.NET Agent requires that the Windows services is running under the "App.pool identity user" account.
• B. AppDynamics .NET Agent supports instrumentation of multiple instances of the same application.
• C. AppDynamics.NET Agent can instrument both 32-bit as well 64-bit processes.
• D. AppDynamics .NET Agent does NOT support instrumenting process running multiple App domains.
• E. AppDynamics.NET Agent automatically discovers all the Windows services to be instrumented.

Answer: B,C

Explanation:
Explanation
The AppDynamics .NET Agent can instrument both 32-bit and 64-bit processes, as long as they are running on a supported .NET Framework version and operating system. The agent automatically detects the process architecture and loads the appropriate profiler DLL. You can also specify the process architecture manually in the agent configuration file1. The AppDynamics .NET Agent also supports instrumentation of multiple instances of the same application, such as Windows services or standalone applications. You can configure the agent to assign different tier and node names for each instance, based on the process name, process ID, or command line arguments. This allows you to monitor the performance and health of each instance separately2.
The other statements are false because:
A: AppDynamics .NET Agent does support instrumenting processes running multiple App domains. The agent can monitor multiple App domains within a single process, as long as they are running the same
.NET Framework version. The agent can also monitor multiple applications within a single App domain, by using the Standalone Applications element in the agent configuration file3.
B: AppDynamics .NET Agent does not automatically discover all the Windows services to be instrumented. The agent automatically instruments IIS applications only. For Windows services or standalone applications, you need to manually configure the agent by editing the agent configuration file and adding the Windows Services or Standalone Applications element. You also need to provide the executable name, tier name, and node name for each service or application4.
D: AppDynamics .NET Agent does not require that the Windows services are running under the
"App.pool identity user" account. The agent can instrument Windows services running under any user account, as long as the account has sufficient permissions to load the agent profiler DLL and access the agent configuration and log files. The "App.pool identity user" account is only required for IIS applications that run in an application pool5.

NEW QUESTION # 30
A company set up an on-premises AppDynamics Controller and an on-premises Events Service cluster. What describes setting up this Events Service cluster?

• A. There is no need for a load balancer or virtual IP address in front of the Events Service cluster.
• B. The Events Service cluster must be able to initiate communication with the Controller.
• C. The Controller must be able to initiate communication with the Events Service cluster.
• D. The Events Service API ports cannot be reconfigured from the default 9080/2081.

Answer: C

Explanation:
Explanation
The Events Service is the on-premises data storage facility for unstructured data generated by Application Analytics, Database Visibility, and End User Monitoring deployments. The Events Service can be deployed as a single node or a cluster of three or more nodes, depending on the data volume and availability requirements.
The Controller and other Events Service clients connect to the Events Service to store and retrieve analytics data. Therefore, it is essential that the Controller is able to initiate communication with the Events Service cluster, using the Events Service API ports (default 9080/2081). The Events Service cluster does not need to initiate communication with the Controller, as it only responds to the requests from the clients. The Events Service API ports can be reconfigured from the default values, if needed, by modifying the conf/events-service-api-store.properties file on each node. However, the clients must also be updated with the new port values. It is also recommended to use a load balancer or a virtual IP address in front of the Events Service cluster, to provide a single endpoint for the clients and to enable load balancing and failover among the nodes. References: Events Service Deployment, Install the Events Service on Linux, and Install the Events Service on Windows in the AppDynamics documentation.

NEW QUESTION # 31
What are three recommended steps to prepare a Linux environment for the installation of an AppDynamics Controller with a Large performance profile? (Choose three.)

• A. Install libaio,
• B. Verify the open file descriptor limit.
• C. Verify the user account has root access,
• D. Verify the process limit.
• E. Install MySQL.
• F. Verify that Java is installed.

Answer: A,B,D

Explanation:
Explanation
To prepare a Linux environment for the installation of an AppDynamics Controller with a Large performance profile, which is suitable for monitoring up to 1000 agents, you need to perform the following steps:
Install libaio on the host machine if it does not already have it installed. This library facilitates asynchronous I/O operations on the system, which are required by the Controller. You can use the package manager of your Linux distribution to install libaio, such as yum or apt-get. For example, on CentOS, you can run yum install libaio1.
Verify the open file descriptor limit on the system. The file descriptor limit determines how many files a process can open at a time. The Controller requires a high file descriptor limit to handle the large number of connections and transactions. AppDynamics recommends setting the file descriptor limit to at least 65535 for the user account that runs the Controller. You can check the current file descriptor limit by running ulimit -n and modify it by editing the /etc/security/limits.conf file2.
Verify the process limit on the system. The process limit determines how many processes a user can run at a time. The Controller requires a high process limit to handle the large number of threads and subprocesses. AppDynamics recommends setting the process limit to at least 65535 for the user account that runs the Controller. You can check the current process limit by running ulimit -u and modify it by editing the /etc/security/limits.conf file2.
Other steps that are not required but recommended for the Controller installation are verifying the user account permissions, configuring the virus scanners, installing the netstat network utility, and setting the NUMA configuration2. You do not need to install MySQL or Java separately, as they are included in the Controller installation package3. References: Prepare Linux for the Controller, Install the Controller on Linux, and Controller System Requirements in the AppDynamics documentation.

NEW QUESTION # 32
What are two advantages of using an Events Service cluster? (Choose two.)

• A. Clusters reduce the load on the AppDynamics Controller.
• B. Clusters are horizontally scalable by adding nodes.
• C. Clusters expose multiple channels for simultaneous queries.
• D. Clusters are easier to maintain than single-node instances.
• E. Clusters allow data replication across multiple nodes.

Answer: B,E

Explanation:
Explanation
An Events Service cluster is a group of two or more Events Service nodes that work together to store and process unstructured data generated by AppDynamics components such as Application Analytics, Database Visibility, and End User Monitoring1. Using an Events Service cluster has two main advantages over a single-node instance12:
Clusters allow data replication across multiple nodes. This means that the data is duplicated and distributed among the nodes in the cluster, providing data redundancy and protection against data loss in case of a node failure. Data replication also improves data availability and query performance, as the cluster can handle concurrent requests from multiple clients.
Clusters are horizontally scalable by adding nodes. This means that the cluster can grow in size and capacity by adding more nodes to the cluster, without affecting the existing nodes or data. Horizontal scaling allows the cluster to handle increasing data volumes and performance demands, as well as balance the workload among the nodes. References: Events Service Deployment, What are the Benefits of Server Clustering?

• A. Custom Timers
• B. Crash Reports
• C. Network Requests
• D. User Data
• E. Breadcrumbs

Answer: B,C

Explanation:
Explanation
The default configuration of the Mobile SDK enables crash reports and network requests12. Crash reports capture and report any unhandled exceptions or signals that cause the app to terminate abnormally1. Network requests monitor the performance and errors of HTTP and HTTPS requests made by the app2. These features are enabled by default and do not require any additional code or configuration to work12. References: Crash Reports, Network Requests

NEW QUESTION # 35
Which implementation mode should be used when deploying an EUM Server with reverse proxy from a security and performance standpoint in a production environment?

• A. Install the EUM Server on the same host as the Controller, in front of the reverse proxy.
• B. Install the EUM Server on a separate host from the Controller, behind the reverse proxy.
• C. Install the EUM Server on the same host as the Controller, behind the reverse proxy.
• D. Install the EUM Server on a separate host from the Controller, in front of the reverse proxy.

Answer: B

Explanation:
Explanation
The EUM Server is the on-premises version of the EUM Cloud that receives, processes, and stores data from EUM agents. For production installation, AppDynamics recommends that the EUM Server and the Controller sit on different hosts, and the EUM Server hosts its own MySQL instance. This improves the scalability and performance of both components. Moreover, AppDynamics strongly recommends that SSL traffic from agents to the EUM Server is terminated at a reverse proxy that sits in front of the EUM Server in the network path, and forwards connections to the EUM Server using HTTP. This relieves the SSL processing load from the EUM Server, simplifies the certificate management, and enhances the security by isolating the EUM Server from the external Internet. Therefore, the best implementation mode for deploying an EUM Server with reverse proxy in a production environment is option D. References: EUM Server Deployment, Install a Production EUMServer, Reverse Proxy configuration for EUM, and Browser EUM installation in the AppDynamics documentation and community.

NEW QUESTION # 36
The Database Agent collects hardware metrics from a Windows database server using_________ . (Choose the correct option to complete the sentence.)

• A. Standalone Machine Agent
• B. SSH
• C. PowerShell
• D. WHI

Answer: C

Explanation:
Explanation
The Database Agent collects hardware metrics from a Windows database server using PowerShell
1. PowerShell is a scripting language and a command-line shell that allows the Database Agent to execute commands and access Windows Performance Counters on the target host12. The Database Agent uses PowerShell to collect metrics such as CPU, memory, disk, and network utilization from the Windows database server1. To enable hardware monitoring for a Windows database server, the Database Agent requires the following permissions1:
The user that runs the Database Agent must have permission to execute PowerShell scripts on the local machine.
The user that runs the Database Agent or the Collector Service user (if using Windows Authentication) must have permission to establish a WMI connection to the target host and collect Windows Performance Counters. References: Required Monitored Host Permissions, PowerShell Overview

The AppDynamics Controller Admin Console lets you configure certain global settings for the Controller, such as metric retention periods, UI notification triggers, tenancy mode, and accounts in multi-tenancy mode1.
Two of the settings that an administrator can configure from the AppDynamics Controller Admin Console are:
License allocation: This setting allows you to view and manage the license usage and availability for your Controller. You can see the total number of licenses, the number of licenses in use, the number of licenses available, and the license expiration date for each agent type. You can also allocate licenses to specific applications or accounts, and set license limits and alerts2.
Retention periods: This setting allows you to specify how long the Controller retains the metric data and the event data for your monitored applications. You can configure the retention periods for different types of data, such as minute-level metrics, hour-level metrics, day-level metrics, transaction snapshots, and events. You can also configure the data purge schedule and the data backup schedule3.

NEW QUESTION # 38
What becomes more important as an AppDynamics Controller grows beyond supporting 500 agents?

• A. RAM allocated to the Controller
• B. Network throughput
• C. CPU utilization
• D. Thread count on the GlassFish server
• E. Disk VO

Answer: B

Explanation:
Explanation
As an AppDynamics Controller grows beyond supporting 500 agents, network throughput becomes more important. This is because the Controller needs to handle a large volume of data from the agents, as well as serve requests from the UI and API clients. Network throughput is the measure of how much data can be transferred over a network in a given time. A low network throughput can cause delays, errors, or timeouts in the communication between the Controller and the agents or clients. Therefore, it is recommended to monitor the network throughput of the Controller and ensure that it meets the minimum requirements for the expected load123.

NEW QUESTION # 39
Which URL retrieves all AppDynamics business applications from an AppDynamics Controller using the AppDynamics Rest API?

• A. http(s)://<cantroller-host=:<part=/controller/rest/businessapplications
• B. http(s)://<controller-host>:<port>/controller/allapplications
• C. http(s)://<controller-host>:<port>/controller/applications
• D. httpis)://<controller-host>:<port>/controller/rest/applications

Answer: D

Explanation:
Explanation
The AppDynamics Rest API allows you to retrieve information and perform operations on the AppDynamics platform using HTTP requests. To retrieve all AppDynamics business applications from an AppDynamics Controller using the AppDynamics Rest API, you need to use the following URL format:
http(s)://<controller-host>:<port>/controller/rest/applications
This URL returns the business application names and internal numeric identifiers for all the applications that are monitored by the Controller. You can use the application name or ID as a parameter for other API methods that require the application context. You can also specify the output format as XML (default) or JSON by adding the output query parameter. For example:
http(s)://<controller-host>:<port>/controller/rest/applications?output=JSON This URL returns the same information as the previous one, but in JSON format. You can also filter the applications by their status (alive or not) by adding the time-range-type query parameter. For example:
http(s)://<controller-host>:<port>/controller/rest/applications?time-range-type=BEFORE_NOW&duration-in-mi This URL returns only the applications that are alive in the last 60 minutes. An alive application is an application with at least one node that submits at least one metric to the Controller in the provided time range12.

NEW QUESTION # 40
Which two preparatory tasks are required prior to installing an AppDynamics Controller on Linux? (Choose two.)

• A. Verify that sufficient temporary (tmp) space is available (at least 1 GB).
• B. Install libaio.
• C. Ensure that MySQL port (3388) is opened.
• D. Install JRE.
• E. Install SSH.

Answer: A,B

Explanation:
Explanation
Before installing an AppDynamics Controller on Linux, you need to perform some preparatory tasks to ensure the system meets the requirements and the installation runs smoothly. Two of these tasks are:
Install libaio on the host machine if it does not already have it installed. This library facilitates asynchronous I/O operations on the system, which are required by the Controller. You can use the package manager of your Linux distribution to install libaio, such as yum or apt-get. For example, on CentOS, you can run yum install libaio1.
Verify that you have enough temporary (tmp) space available on the system, at least 1 GB. The Controller installation uses the tmp space to extract and install the software components. You can check the tmp space by running df -h /tmp2. If the tmp space is insufficient, you can either free up some space by deleting unnecessary files, or specify a different temporary directory for the installation by passing the -Djava.io.tmpdir parameter to the installer3.
Other preparatory tasks include verifying the user account permissions, configuring the virus scanners, installing the netstat network utility, and setting the file descriptor limit2.
