Question #2
What are two supported ESXi boot options? (Choose two.)
- ANFS
- BiSCSIMost Voted
- CvSAN
- DSANMost Voted
- EvSphere Virtual Volumes
Correct Answer:
BD
BD

The correct boot options for ESXi, as noted in VMware's documentation, are iSCSI and SAN. These allow for the deployment of ESXi on network storage devices, ensuring that even in environments where local storage is minimal or non-existent, ESXi can still be efficiently loaded and operated. Importantly, ESXi capitalizes on the redundancy and speed offered by SAN and iSCSI solutions to manage and maintain optimal performance and reliability, which are critical for production environments relying on virtualized infrastructure.

Question #3
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?
Which behavior should the administrator expect while deleting the snapshot?
- AESXi will create a virtual RAM disk to cache ongoing database write activity; performance impact will be limited.
- BESXi will commit the snapshot delta disk into the base disk; ongoing database write activity could result in long stun times.Most Voted
- CESXi will merge the snapshot delta disk into the base disk; the virtual machine will be briefly stunned.
- DESXi will instantly switch from the base disk to the snapshot delta disk with no performance impact.
Correct Answer:
B
B

When an administrator deletes a large snapshot like the 1TB in the scenario described, the deletion process involves committing the snapshot’s delta disk back into the base disk. This process, especially with a high-write intensity environment such as a database server, can considerably impact the performance of the virtual machine. The longer duration and large size of the snapshot often result in extended VM stun times, during which no other operations can proceed on the VM, potentially affecting performance and availability. Therefore, careful planning and timing are crucial when managing snapshots on production VMs to minimize disruption.

Question #5
An administrator runs a two-node vSphere cluster, which contains two domain controller virtual machines (VMs). The administrator wants to ensure that VMs run on separate hosts without interfering with normal maintenance operations.
How should the administrator configure Distributed Resource Scheduler (DRS)?
