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 -B. ESXi will commit the snapshot delta disk into the base disk; ongoing database
write activity could result in long stun times.

,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
E. iSCSI storage - ✅✅✅CORRECT -A. Fibre Channel storage
E. iSCSI storage
VMFS can be deployed on three kinds of SCSI-based storage devices:
• Direct-attached storage
• Fibre Channel storage
• iSCSI storage
In order for a filesystem to be made, the underlying storage must be block-based. VSAN and virtual
volumes are object-based and NFS is file-based.
What should be done to apply a guest OS patch to an existing template?
A. upload patch to VUM
B. revert to snapshot
C. use template wizard
D. convert the template to VM - ✅✅✅CORRECT -D. convert the template to VM
A vSphere administrator requires to be alerted whenever a host power state changes. How can this be
done with alarms?
A. Set condition to Show as Critical.
, B. Enable Power Alarm in DCUI.
C. Enable Send Email notifications.
D. Enable DPM on the cluster. - ✅✅✅CORRECT -C. Enable Send Email notifications.
The storage administrator has decided to use NAS in a deployment. Which hardware acceleration API
should be used to change the virtual disk file?
A. reserve space
B. full file clone
C. native snapshot support
D. write the same - ✅✅✅CORRECT -A. reserve space
Which TCP/IP stack can support management traffic, vSphere vMotion, IP storage and vSphere Fault
Tolerance?
A. vSphere vMotion TCP/IP stack
B. Default TCP/IP stack
C. VXLAN TCP/IP stack
D. Provisioning TCP/IP stack - ✅✅✅CORRECT -B. Default TCP/IP stack

A recently deployed set of test virtual machines are impacting the performance of a company
development team project datastore. The shared cache server appears to be suffering from storage
congestion.Storage I/O Control is already enabled on all company datastores.Which two steps should the
administrator take to improve the performance of the cache server? (Choose two.)
A. Update the storage provider for the existing array.
B. Configure storage shares per virtual machine.
C. Create a claim rule to control the storage path.
