In a vSAN stretched cluster, what is the role of the witness host?

To host virtual machines in the event of a site failure

To provide a tie-breaking vote in the event of a network partition between the two data sites

To store a full copy of all virtual machine data

To act as a backup for the primary site's storage

An administrator suspects a vSAN network issue because a host is showing as 'partitioned' from the cluster. What does a network partition in vSAN typically indicate?

The host is running an incompatible version of ESXi

The host's storage controller has failed

The host's vSAN performance service is not responding

The host cannot communicate with other hosts over the vSAN network

What is the role of the cache device in a vSAN disk group?

To store all data persistently for the disk group

To provide additional capacity for virtual machine storage

To provide read and write caching for the capacity devices in the disk group

To manage the disk group's metadata and configuration

What is the primary purpose of the vSAN Compatibility Guide?

To show the default storage policies for vSAN

To list all supported hardware and software versions for vSAN

To display the current health status of the vSAN cluster

To provide step-by-step instructions for upgrading vSAN

A vSAN cluster is using a single VMkernel adapter for vSAN traffic. The administrator notices that the vSAN network is experiencing high packet loss and latency. The physical switches are configured with Jumbo Frames (MTU 9000). The vSphere distributed switch is configured with MTU 9000, but the vSAN VMkernel adapter is configured with MTU 1500. What is the most likely cause of the network issue?

The VMkernel adapter is not configured with the correct MTU, causing fragmentation and performance issues.

The vSAN VMkernel adapter is not on the same subnet as the other hosts, causing routing issues.

The vSAN cluster is using multicast, which is not supported with Jumbo Frames.

The vSAN health service is not enabled, so the network checks are not running.
