EMC E20-918 Exam Syllabus Topics:

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

1. You are a cloud consultant recently assigned to help an international pharmaceutical manufacturer implement ITaaS. The company has a well-staffed, highly technical IT organization.
There are concerns that implementing ITaaS will be met with resistance, because the IT group may feel that their job security is threatened.
You are seeking an individual within the organization to fill the role of Executive Sponsor for the ITaaS transformation project. Which individual would be the best candidate to fill this role?

A) The Vice President of Operations, who is a good communicator and understands ITaaS as it relates to the business
B) A senior Finance executive with a familiarity of ITaaS, who is focused on cost savings possible with ITaaS
C) The CIO, who has close ties to the IT organization and is focused on emerging technologies for ITaaS
D) A member of the Board of Directors, who holds a high enough position in the organization to drive change

2. A company has deployed a fully operational, private PaaS service. The service catalog links to an orchestration engine that builds servers automatically.
What is the primary reason the IT security risk team is proposing the use of strong authentication for all service catalog users?

A) Because the catalog is responsible for the authentication of users who manage the CMDB, they must be strongly authenticated.
B) Because the catalog is used to define service contracts, an unauthorized user could adjust service level agreements.
C) Because the catalog triggers orchestration actions, an unauthorized user can trigger a denial of service attack.
D) Because the catalog is used to define resource pools, an unauthorized user could impact the production systems.

3. What is a key design consideration for a service provider to ensure that they can effectively process the termination of a service instance?

A) Provide a chargeback bill or showback report
B) Archive the associated service data regardless of the user requirements
C) Incorporate a service grace period to prevent the actual deletion of the instance
D) Incorporate a retention period for private user data and user PCI data

4. Refer to Scenario 5.
Refer to the exhibit.

An innovative high-end graphics and multimedia 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.
-- Exhibit -
Your second goal is to demonstrate that the CSP solution will be suitable for even the most time consuming backups.
Which application would you select for this test?

A) Accounting
B) Development
C) Legal
D) Email

5. Refer to Scenario 7.
-- Exhibit -
Scenario 7.
A web hosting company has been growing steadily over the past year. Their single data center is at maximum capacity for power, space and cooling, and their physical infrastructure is also running at capacity. They are evaluating the feasibility of obtaining another data center in a remote location to enable further growth.
One of the web hosting company's eCommerce customers notifies them that they are launching an enormous holiday sale, beginning in a few weeks. They expect utilization of their virtual server farm to double or triple for the next three to six months. The web hosting company cannot deploy the needed resources in a new data center in time for the sale. They opt to purchase services from a cloud service provider using a pay-as-you-go model.
Over the next two weeks, Layer 2 connectivity is established between the two sites. The web hosting company's IT staff works with the CSP to configure the necessary physical and virtual infrastructure. All traffic to the public cloud is routed through the private data center, across the Layer 2 connection. A local load balancer is deployed in the private data center. Orchestration tools are configured to burst the service into the public cloud automatically when utilization reaches 80%.
-- Exhibit -
To test the functionality of the new infrastructure, a load simulator is used to increase utilization on the servers. At 80% utilization, the orchestration tools provision the required resources in the public cloud. However, the utilization on the private cloud resources continues to increase, while the utilization on the public cloud resources remains at 0%.
What is the most likely cause of this problem?

A) The wrong VLANs are configured across the network link
B) The wrong subnets are configured across the network link
C) The local load balancer is not being updated with the new service information
D) The global load balancer is not being updated with the new service information
