D. It will be cheaper than hosting the application in-house.

A. Cloud elasticity means the application can grow or shrink

relative to business needs.
B, C, and D are incorrect. Data encryption and high availability are
available without migrating an application to the cloud. Even though
CAPEX gets shifted to OPEX, when viewed over time, cloud solutions
are not always cheaper than in-house solutions.

41. Which of the following items would show up in an SLA? (Choose all

that apply.)
A. Type of virtual server operating systems available

B. PKI certificate for identity federation
C. Degree of service elasticity

D. Guaranteed level of service

C and D. Service elasticity, that is, the ability to increase or
decrease a cloud service such as the number of user mailboxes, should

be stated in the SLA. All SLAs state the expected level of service
cloud customers can expect and the repercussions if those service
levels are not met.
A and B are incorrect. The type of operating system used in virtual
machines, along with PKI certificate details, are not relevant to the
SLA, even though they might be of technical relevance.

42. Cloud adoption can increase the workload for cloud customer internal

IT staff members in which way?
A. Applying software patches

B. Acquiring server hardware
C. Monitoring cloud service performance

D. Performing data backups

C. With cloud adoption, IT staff members will find themselves
focusing more on the delivery, monitoring, and maintenance of IT

services.
A, B, and D are incorrect. Applying software patches, acquiring
server hardware, and performing backups are tasks performed by the
cloud provider.
