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. Legal
• C. Email
• D. Development

Refer to Scenario 1 below.
An IT department is offering 50 Service Offerings in their service catalog to meet all the application developers' needs. Many of the variants have a very small number of associated instantiations. A "big data" platform is offered and being actively utilized by a team of data scientists.
All services are sourced from within the private cloud. The developers are able to customize the platform's compute, storage, protection and network configuration upon instantiation. They can also provision additional resources after the initial instantiation through an upgrade service within the catalog. Because of the culture of the organization, no chargeback mechanism is implemented.
What can the IT department do to resolve problems (b) and (d)?

• A. Provide separate resource pools for the application developers and the data scientists and manage the pools separately
• B. Decrease the number of IaaS offering variations and customization options
• C. Standardize on a subset of offerings to meet the needs of most developers and minimize the number of customization options
• D. Meter usage patterns and implement a showback mechanism to influence consumer behavior when choosing specific resources

The first phase of new ITaaS service introduces the offering to 10% of the engineering organization. The IT organization leverages the management tools used in their traditional data center processes to provide visibility into silos and control of the infrastructure. They also have adapted some ITSM concepts as a framework for their management practices.
During the initial phase of the service deployment, a problem was encountered in one of the VMs.
The IT organization is concerned about the extensive amount of time and resources spent determining the cause of the issue.
What is the most likely reason it takes more time than expected to resolve the problem?

• A. The legacy management tools do not have the capability to provide a holistic view of the service instance
• B. The complex nature of orchestration and automation makes problem identification and root cause analysis unlikely.
• C. The expertise of the service desk personnel is inadequate to properly handle service related issues
• D. The cultural hurdles that span organizational silos have not been addressed and resolved.

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. B, because it satisfies both the primary and secondary goals
• C. B, because it satisfies the primary goal
• D. A, because it satisfies both the primary and secondary goals

Refer to the exhibit.

You have been hired to assist with a migration to an ITaaS environment. The company has offices
in Atlanta, Dubai, and London, with 5000, 2000, and 3000 employees, respectively. A data center exists in each location, and most services have been virtualized. Messaging services are provided locally to the user.
You have just performed an assessment of the environment. The results are shown in the exhibit.
The CIO is interested in closing one of the data centers and migrating some or all of the services to a public cloud service provider (CSP). Any services that do not get migrated to the CSP will be hosted at one of the other two data centers. Network latency averages 8 milliseconds between the Atlanta and London offices, and 10 milliseconds between the London and Dubai offices. Traffic between Atlanta and Dubai is routed through London.
The eCommerce application is external facing and is hosted at all three data centers. Atlanta services 50% of the users in North and South America. London services 40% of the users in Europe and Asia. Dubai services 10% of the users in Africa and Australia.
You have tentatively chosen a CSP that is housed in Frankfurt, and would have access to 3 Gb/s of network bandwidth to the facility. The CSP's service levels are as follows:
-RPO: 4 hours -RTO: 1 hour -Availability: 99.995%
Your recommendation is to close the Dubai data center over a one-year time horizon.
What migration strategy would you recommend for the services that are currently hosted in the Dubai data center, and why?

• A. Messaging and eCommerce to the public cloud; CSP can support availability and bandwidth requirements for both applications
• B. eCommerce to the public cloud; Messaging to London; CSP cannot support the bandwidth requirements for Messaging, and latency will be less from London
• C. eCommerce to the public cloud; Messaging to Atlanta; CSP cannot support the bandwidth requirements for Messaging, and latency will be less from Atlanta
• D. Messaging to the public cloud; split eCommerce between London and Atlanta; CSP cannot support the availability for eCommerce
