EMC E20-918 Exam Syllabus Topics:

EMC IT-as-a-Service Expert Exam for Cloud Architects Sample Questions:

1. A company is actively moving business applications to an ITaaS model. The IT department increasingly acts as an adviser, proposing the best fit from either private cloud capability or public cloud suppliers.
The company's finance department is considering their financial applications for cloud as they increasingly need more capacity and better performance at the end of the month, which the current infrastructure cannot deliver. The financial application architecture is three tier (presentation, middleware, and database).
The IT security team has suggested that with appropriate controls the presentation layer could be deployed in a public cloud but the middleware and database layers cannot.
What would be the best approach to enabling service elasticity in this scenario?

A) IaaS deployment in the private cloud
B) IaaS deployment in the public cloud
C) IaaS deployment in the hybrid cloud
D) IaaS deployment in the community cloud

2. Refer to the exhibit.

A company is evaluating an ITaaS architecture to provision applications for their various business units. The IT architects consult you for help on the illustrated design.
What is a potential risk in the design?

A) Unbalanced resource utilization
B) Multi-tenancy
C) CPU resource contention
D) Memory resource contention

3. A public cloud service provider has stated they intend to improve their IT capabilities in the following areas:
1 - Monitor storage usage patterns and identify bottlenecks
2 - More comprehensive element management
3 - Holistic visibility across their storage services
4 - VMware provisioning
5 - Identifying opportunities to move data to more cost effective storage
Which three areas is ProSphere best suited to address?

A) 3, 4, and 5
B) 1, 3, and 5
C) 1, 2, and 3
D) 2, 3, and 4

4. Refer to the exhibit.

A small insurance company wants to extend their website to the public cloud for elasticity and high availability. After reviewing the exhibit, what suggestion would you make to ensure expectations will be met?

A) Add a web server to the public cloud to ensure proper balance
B) Modify the application using DevOps to be cloud compliant
C) Upgrade the firewall to a newer version to support load balancing and QoS
D) Add a secondary DNS server to the enterprise data center

5. Refer to Scenario 4.
A construction firm with a substantially virtualized IT infrastructure wishes to consider cloud
enablement next, as part of its logical progression to ITaaS.
As a first step, the firm plans to transition one relatively low-risk service -- daily backup -- to a public CSP. The existing backup strategy involves array-based cloning, followed by backup of the clones with dedicated servers. The system is functional; however, since the backup target device is due for a technology refresh, the firm is open to alternatives.
In evaluating alternatives, the key consideration is the ability to meet backup windows for daily incremental backups during the work week.
As advisor to this firm, you have conducted a quick assessment of the candidate applications and storage involved in daily backups. Relevant details are presented in the exhibit.
Another evaluation point is the completion time for weekly full backups to the cloud service provider. Which would have the most favorable impact on full backup speed?

A) Low growth rate for volumes
B) Target-based deduplication
C) Low IOPS per GB for volumes
D) Source-based deduplication
