  A. automated scaling listener

  B. pay-for-use monitor

  C. multi-device broker

  D. resource replicator

  Correct Answer: B

• Question 73:

  A virtual server is being attacked by a malicious cloud service consumer that is generating increased usage loads upon the underlying physical server. As a result, other virtual servers being hosted by the physical server are becoming unavailable to other cloud service consumers. This kind of attack is known as: . Select the correct answer.

  A. denial of service

  B. overlapping trust boundary

  C. insufficient authorization

  D. buffer overrun

  Correct Answer: A

• Question 74:

  The attack occurs when access is granted to an attacker erroneously or too broadly, resulting in the attacker gaining access to IT resources that are normally protected. Select the correct answer.

  A. denial of service

  B. malicious intermediary

  C. insufficient authorization

  D. virtualization

  Correct Answer: C

• Question 75:

  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.

  Correct Answer: C

• Question 76:

  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.

  Correct Answer: B

• Question 77:

  Correct Answer: AC

• Question 79:

  Which of the following statements are true about the state management database mechanism? SELECT ALL THAT APPLY

  A. Software programs can off-load state data to a state management database in order to reduce the amount of runtime memory they consume.

  B. The use of a state management database can improve scalability.

  C. State management databases rely on the use of virtualization software.

  D. The use of state management databases requires a ready-made environment.

  Correct Answer: AB
