VMware vSphere 6.5 Foundations (VCP6.5-DCV) — Question 86

An administrator has been tasked with enabling High Availability (HA) on a cluster in a vSphere 6.x environment with default settings. The cluster configures properly and there are no errors.
The next day when powering on a virtual machine, an error is presented:

Not Enough Failover Resources -
Which three scenarios are likely causes of this error message? (Choose three.)

Answer options

• A. The default VM Monitoring Sensitivity is set too high.
• B. There are not enough datastore heartbeat datastores configured by default.
• C. The default slot size in the cluster is set too high.
• D. There are virtual machines with large CPU reservations.
• E. A host is in maintenance mode for a replacement of a failed Hard Drive.

Correct answer: C, D, E

Explanation

The correct answer includes scenarios that limit the available resources for failover. An excessively high default slot size (C) can reduce the number of virtual machines that can failover, large CPU reservations (D) can also consume resources necessary for HA, and having a host in maintenance mode (E) means it's not contributing to the cluster's failover capacity. Options A and B do not directly affect the failover resource availability in this context.
