Question #1

With cloud storage, consumers only pay for the actual storage they use. Select the correct
answer.

A. True

B. False

Question #2

Which of the following security mechanisms enables one cloud service consumer to be
authenticated by a security broker, so that its security context is persisted when accessing
other cloud services? Select the correct answer.

A. digital certificates

B. certificate authority

C. single sign-on

D. None of the above.

Question #3

REST services share a uniform contract and therefore cannot be deployed in cloud
environments without a multi-device broker mechanism. Select the correct answer.

A. True

B. False

Question #4

In a cloud bursting environment, cloud-based IT resources typically remain idle until an
actual cloud burst occurs. Select the correct answer.

A. True

B. False

Question #5

Which cloud computing mechanism is used to maintain synchronicity between on-premise
and cloud-based IT resources? Select the correct answer.

A. automated scaling listener

B. failover system

C. pay-for-use monitor

D. None of the above.

Question #6

Cloud services can be built as components because Web-based communication is not an
essential requirement for an IT resource to be considered cloud-based. Select the correct
answer.

A. True

B. False

Question #7

The resource replication mechanism can encompass a hypervisor that can support the
multitenancy cloud characteristic. Select the correct answer.

A. True

B. False

Question #8

White box testing is commonly used with which of the following cloud delivery models?
SELECT ALL THAT APPLY

A. Infrastructure-as-a-Service (IaaS)

B. Platform-as-a-Service (PaaS)

C. Software-as-a-Service (SaaS)

D. Replicated Software-as-a-Service (SaaS)

Question #9

We exported data from our on-premise relational database to a cloud-based non-relational
database. After the export, we noticed that the size of the cloud-based database was
significantly larger than our on-premise database. What is the likely reason that the
database size increased? Select the correct answer.

A. The transmission of the data over a wide area network resulted inthe accumulation of additionalmeta data from HTTP headers that was stored in the non-relational database, resulting in the increase in data received by the cloud.

B. The data in the relational database was normalized and became denormalized after being exported into a non-relational database.

C. In order to support higher levels of scalability, the cloud-based database is required to add state data to the non-relational data it stores. This state data is used to synchronize instances of the database tables during runtime usage, but also increases the size of the overall database.

D. All of the above.

Question #10
