Correct Answer:

Scaling out is correct.

Scaling out increases the number of VMs to support a workload.

Incorrect Answers:

Scaling in is incorrect. Scaling in reduces the number of virtual machines.

Scaling up is incorrect. Scaling up increases compute power.

Scaling down is incorrect. Scaling down reduces compute power.

Correct Answer:

Application containers are lightweight, portable environments that contain software and its dependencies, but not an operating system. The container uses the underlying OS kernel.

Incorrect Answers:

Application compression is incorrect. There is no such thing as application compression.

Scaling out is incorrect. Scaling out adds virtual machines to support an application.

Dynamic memory is incorrect. Dynamic memory increases and decreases virtual machine memory as needed.

Correct Answer:

Correct Answers:

Power efficiency and space efficiency are correct.

Because virtualized servers could be running on the same physical host, patch deployment is efficient. Virtualized servers often use shared disk storage, thus centralizing data and making backups quicker and easier.

Incorrect Answers:

Faster networking is incorrect. Virtualized servers are not faster than physical servers.

Cheaper software licensing is incorrect. Licensing for virtualized servers is normally not cheaper than with physical servers.

Correct Answer:

A cloud database server deployment is an example of Platform as a Service (PaaS).

Incorrect Answers:

A cloud office suite is an example of PaaS is incorrect. A cloud office suite is an example of Software as a Service (SaaS).

A cloud telecommunications suite is an example of PaaS is incorrect. A cloud telecommunication suite is an example of Communications as a Service (CaaS).

A cloud virtual machine deployment is an example of PaaS is incorrect. A cloud virtual machine deployment is an example of Infrastructure as a Service (IaaS).

Correct Answer:

Data integrity is correct.

Hashing uses a one-way function that results in a hash. If anything changes in the data, recomputing the hash results in a different hash value, which implies the data has been modified.

Incorrect Answers:

Confidentiality is incorrect. Encryption provides confidentiality; this scrambles data so that only authorized users can decrypt the ciphertext.

Availability is incorrect. Availability is achieved with solutions such as data backups and failover clustering.

Encryption is incorrect. Encryption provides confidentiality; this scrambles data so that only authorized users can decrypt the ciphertext.

Correct Answer:

Blue-green deployment is correct.

Blue-green testing uses two environments for a given application: one for testing, the other for production.

Incorrect Answers:

The other listed descriptions are incorrect.

Correct Answer:

Run the PowerShell cmdlet Restart-Computer is correct.

The Restart-Computer PowerShell cmdlet will reboot a system.

Incorrect Answers:

Restart the server from the Start menu is incorrect. Server Core does not have a GUI; therefore there is no Start menu.

Restart the server from Server Manager over RDP is incorrect. Server Core is installed without a GUI; therefore Server Manager is not available.
