NEW QUESTION 2
An administrator wants to leverage the processor-specific technology that uses a security extension for securing virtual machines (VMs). This will allow user-level code to define private regions of memory called enclaves that are protected from external access.

• D. Transparent Page Sharing (TPS)

Answer: B

NEW QUESTION 3

Which DRS automation level should the administrator select? (Choose the best answer.)

• A. Manual
• B. Partially automated
• C. Fully automated
• D. Disabled

Answer: B

NEW QUESTION 9
An administrator receives an escalation to investigate a low disk space alarm on a datastore. The administrator discovers that a snapshot has been accidentally taken on a production, write-intensive database server. The snapshot has grown to nearly 1 TB in size in less than an hour and continues growing every second. Which behavior should the administrator expect while deleting the snapshot? (Choose the best answer.)

• A. ESXi will create a virtual RAM disk to cache ongoing database write activity; performance impact will be limited.
• B. ESXi will commit the snapshot delta disk into the base disk; ongoing database write activity could result in long stun times.
• C. ESXi will merge the snapshot delta disk into the base disk; the virtual machine will be briefly stunned.
• D. ESXi will instantly switch from the base disk to the snapshot delta disk with no performance impact.

Answer: B
