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 -
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. Use of thin provisioning for volumes
• B. Source-based deduplication
• C. Target-based deduplication
• D. Low capacity growth rate for volumes

Refer to the exhibit.

You are discussing a network design that a cloud service provider has proposed for a tenant. The tenant states that one more firewall is required, and you agree.
Where should the firewall be placed?

• A. Between VM2 and the tenant network
• B. Between VM2 and VM4
• C. Between the tenant network and the external network
• D. Between the Service A and Service B

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. Memory resource contention
• B. Multi-tenancy
• C. CPU resource contention
• D. Unbalanced resource utilization

The marketing line of business of an enterprise has deployed web services within a private cloud. They wish to provide additional web services elastically and distribute them around the globe using a public cloud provider.
The web services have a loosely coupled design and have no content dependencies on any resources in the private cloud. They are created from a standard PaaS template, which includes an intrusion prevention system that periodically polls a central management server for security updates. The IPS management server is located within the private cloud. No layer 2 connectivity exists between the private and public clouds. The consumers of these web services are distributed across the globe.
Which solution would you recommend to best support the web service elasticity and to minimize service network latency for the consumer?

• A. Deploy a central database server to consolidate web service content.
• B. Implement a global load balancing service as a front-end for the web services.
• C. Increase bandwidth between the private cloud and the Internet.
• D. Implement an encrypted VPN tunnel between the private and public clouds.
