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.

Which TCP/IP stack can support management traffic, vSphere vMotion, IP storage and vSphere Fault Tolerance? (Choose the best answer.)

A. VXLAN TCP/IP stack

B. Provisioning TCP/IP stack

C. Default TCP/IP stack

D. vSphere vMotion TCP/IP stack

An administrator wants to ensure that when virtual machines (VMs) are powered on, Distributed Resource Scheduler (DRS) places them on the best-suited host. When the cluster becomes imbalanced, the administrator wants DRS to display recommendations for manual VM migration.

A. Manual

B. Partially automated

C. Fully automated

D. Disabled

A. Cross vCenter Migration

B. vSphere High Availability

C. vSphere vMotion

D. vSphere Replication
