QUESTION 1
What are two supported ESXi boot options? (Choose two.)

A. NFS
B. iSCSI
C. vSAN
D. SAN
E. vSphere Virtual Volumes

Correct Answer: AB

QUESTION 2
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.

Correct Answer: A

QUESTION 3
Which two storage technologies can an administrator use to deploy the Virtual Machine File System (VMFS)?
(Choose two.)

A. Fibre Channel storage
B. vSAN storage
C. Virtual Volumes storage
D. NFS storage
