NEW QUESTION 15
Which Oracle Cloud Infrastructure service allows you to run code without provisioning any underlying infrastructure resources?
- A. Oracle Functions
- B. Oracle Container Engine for Kubernetes
- C. Storage Gateway
- D. Compute service
Answer: A
Explanation:
Explanation
Oracle Functions is a fully managed, multi-tenant, highly scalable, on-demand, Functions-as-a-Service platform. It is built on enterprise-grade Oracle Cloud Infrastructure and powered by the Fn Project open source engine. Use Oracle Functions (sometimes abbreviated to just Functions) when you want to focus on writing code to meet business needs.
The serverless and elastic architecture of Oracle Functions means there's no infrastructure administration or software administration for you to perform. You don't provision or maintain compute instances, and operating system software patches and upgrades are applied automatically. Oracle Functions simply ensures your app is highly-available, scalable, secure, and monitored. With Oracle Functions, you can write code in Java, Python, Node, Go, and Ruby (and for advanced use cases, bring your own Dockerfile, and Graal VM). You can then deploy your code, call it directly or trigger it in response to events, and get billed only for the resources consumed during the execution.

Which Oracle Cloud Infrastructure service leverages Terraform to configure infrastructure as code?
- A. Events
- B. Oracle Functions
- C. Compartment Explorer
- D. Resource Manager
Answer: D
Explanation:
Explanation
Resource Manager is an Oracle Cloud Infrastructure service that allows you to automate the process of provisioning your Oracle Cloud Infrastructure resources. Using Terraform, Resource Manager helps you install, configure, and manage resources through the "infrastructure-as-code" model.
A Terraform configuration codifies your infrastructure in declarative configuration files. Resource Manager allows you to share and manage infrastructure configurations and state files across multiple teams and platforms. This infrastructure management can't be done with local Terraform installations and Oracle Terraform modules alone. For more information about the Oracle Cloud Infrastructure Terraform provider, see Terraform Provider. For a general introduction to Terraform and the "infrastructure-as-code" model, see https://www.terraform.io.

Which service is the most effective for moving large amounts of data from your on-premises to Oracle Cloud Infrastructure (OCI)?
- A. Dynamic Routing Gateway
- B. Data Transfer appliance
- C. Data Safe
- D. Internet Gateway
Answer: B
Explanation:
Explanation
APPLIANCE-BASED DATA TRANSFER
You send your data as files on secure, high-capacity, Oracle-supplied storage appliances to an Oracle transfer site. Operators at the Oracle transfer site upload the data into your designated Object Storage bucket in your tenancy.
This solution supports data transfer when you are migrating a large volume of data and when using disks is not a practical alternative. You do not need to write any code or purchase any hardware. Oracle supplies the transfer appliance and software required to manage the transfer.
https://docs.cloud.oracle.com/en-us/iaas/Content/DataTransfer/Concepts/overview.htm Oracle Cloud Infrastructure Data Transfer Appliance securely moves terabytes or petabytes data between on-premise data centers and the cloud. The service reduces data migration times from weeks or months to just hours and is available for data import to the cloud and data export from the cloud.
NEW QUESTION 21
What purpose does an Oracle Cloud Infrastructure (OCI) Dynamic Routing Gateway Serve?
- A. Enables OCI Compute instance to connect to on-promises environments
- B. Enables OCI Compute instances to be reached from internet
- C. Enable OCI Compute instances to connect to the internal
- D. Enables OCI Compute Instance to privately connect to OCI Object Storage
Answer: A
Explanation:
Explanation
You can think of a Dynamic Routing Gateway (DRG) as a virtual router that provides a path for private traffic (that is, traffic that uses private IPv4 addresses) between your VCN and networks outside the VCN's region.
For example, if you use an IPSec VPN or Oracle Cloud Infrastructure FastConnect (or both) to connect your on-premises network to your VCN, that private IPv4 address traffic goes through a DRG that you create and attach to your VCN. For scenarios for using a DRG to connect a VCN to your on-premises network, see Networking Scenarios. For important details about routing to your on-premises network, see Routing Details for Connections to Your On-Premises Network.
Also, if you decide to peer your VCN with a VCN in another region, your VCN's DRG routes traffic to the other VCN over a private backbone that connects the regions (without traffic traversing the internet). For information about connecting VCNs in different regions, see Remote VCN Peering (Across Regions).

Which statement is correct regarding the oracle cloud infrastructure Compute services?
- A. You can attach a maximum of one public to each compute instance
- B. When you stop a compute instance, all data on the boot volume is lost
- C. You can launch either virtual machines or bare metal instances
- D. You cannot attach a block volume to a compute instance
Answer: C
Explanation:
Explanation
Oracle Cloud Infrastructure Compute lets you provision and manage compute hosts, known as instances You can launch instances as needed to meet your compute and application requirements. After you launch an instance, you can access it securely from your computer, restart it, attach and detach volumes, and terminate it when you're done with it. Any changes made to the instance's local drives are lost when you terminate it. Any saved changes to volumes attached to the instance are retained.
Oracle Cloud Infrastructure offers both bare metal and virtual machine instances:
1) Bare Metal: A bare metal compute instance gives you dedicated physical server access for highest performance and strong isolation.
2) Virtual Machine: A virtual machine (VM) is an independent computing environment that runs on top of physical bare metal hardware. The virtualization makes it possible to run multiple VMs that are isolated from each other. VMs are ideal for running applications that do not require the performance and resources (CPU, memory, network bandwidth, storage) of an entire physical machine.
An Oracle Cloud Infrastructure VM compute instance runs on the same hardware as a bare metal instance, leveraging the same cloud-optimized hardware, firmware, software stack, and networking infrastructure.
