Refer to the Exhibit. An administrator receives the error message shown in the Exhibit. Which two actions can be taken to clear the warning? (Choose two.)

The correct answer is C. Set the advanced High Availability parameter Das.ignoreInsufficientHbDatastore to true. D. Add a shared datastore and reconfigure High Availability.. vSphere HA requires at least two heartbeat datastores per host; the warning can be suppressed via an advanced parameter or resolved by adding a qualifying shared datastore.

Why each option

vSphere HA requires at least two heartbeat datastores per host; the warning can be suppressed via an advanced parameter or resolved by adding a qualifying shared datastore.

AAdd a Virtual SAN datastore and configure it for High Availability heartbeating.

Virtual SAN datastores are not supported as HA heartbeat datastores because vSAN itself relies on the same network, creating a circular dependency that HA cannot use for out-of-band heartbeating.

BSet the advanced High Availability parameter Das.heartbeatdsperhost to 1.

Das.heartbeatdsperhost controls the desired number of heartbeat datastores per host; setting it to 1 lowers the requirement but is not a recognized resolution method and does not directly clear this specific warning the same way the correct parameters do.

CSet the advanced High Availability parameter Das.ignoreInsufficientHbDatastore to true.Correct

Setting Das.ignoreInsufficientHbDatastore to true instructs vSphere HA to suppress the warning about insufficient heartbeat datastores without actually changing the infrastructure, which is acceptable when adding datastores is not possible.

DAdd a shared datastore and reconfigure High Availability.Correct

Adding a shared (NFS or VMFS) datastore gives vSphere HA the additional heartbeat datastore it needs, and reconfiguring HA allows the cluster to detect and register the new datastore for heartbeating, resolving the root cause.
