EMC IT-as-a-Service Expert Exam for Cloud Architects Sample Questions:
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.
Your first goal in this proof-of-concept is to demonstrate one quick and successful backup run to the CSP for two different customer applications.
Which two applications would you select, if your desired outcome is backup completion within the shortest possible time?
- A. HR and CRM
- B. Messaging and CRM
- C. Messaging and SCM
- D. CRM and SCM
Correct Answer: A 🗳️
A company is deploying a major new business application. The application development has been outsourced to several organizations.
The company has conducted several workshops with all suppliers and the testing team. The outcome of their efforts is a streamlined process that has dramatically reduced the cycle time from development to test, improved communications between all groups, and implemented common standards and objectives.
What have they achieved?
- A. Transition to a DevOps culture
- B. Use of common automation and orchestration processes
- C. Implementation of common collaboration tools
- D. Utilization of configuration management methodologies
Correct Answer: A 🗳️
A small company has been using a public cloud IaaS provider for several months. During this time the company has seen significant growth in revenue. This growth has triggered a surge in hiring, which has forced the company to repeatedly purchase additional services at premium cost from their CSP.
The company has leased a data center and started designing a cloud infrastructure to deploy a private cloud environment. The underlying hypervisor technology they chose is different than that of the CSP. Once the initial infrastructure has been implemented, they will transition to a hybrid cloud model. New services will only be deployed in the private cloud.
A new CIO has just been hired, but has little experience with cloud computing. You are a Cloud Architect who has been asked to consult on several areas of concern.
The first service must be deployed in the private cloud within the next month. The CIO does not want to rely solely on the existing single sign-on solution hosted in the public cloud, because network disruption between the clouds would impact user access.
What is the best option for an interim single sign-on solution that can be replaced once the private cloud is fully implemented?
- A. OAuth
- B. SAML
- C. Identity Provider
- D. Public Key Infrastructure
Correct Answer: C 🗳️
What is a key design consideration for a service provider to ensure that they can effectively process the termination of a service instance?
- A. Incorporate a retention period for private user data and user PCI data
- 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. Automate the de-provisioning process to release resources
Correct Answer: D 🗳️
An enterprise wants to deploy a single sign-on solution to utilize within their private cloud environment. Their developers are experienced with the REST protocol, and they have a large number of interns that are employed May through August every year.
Their primary goal is to build a solution that utilizes the REST protocol. Their secondary goal is to be able to bulk load credentials for the interns into the system each year.
They have asked you to review the offerings from two identity providers. The results of your analysis are shown below:
-Provider A supports OpenID and OAuth -Provider B supports OAuth and SCIM
Which provider would you recommend, and why?
- A. A, because it satisfies the primary goal
- B. A, because it satisfies both the primary and secondary goals
- C. B, because it satisfies the primary goal
- D. B, because it satisfies both the primary and secondary goals
Correct Answer: D 🗳️
