When a vSphere administrator attempts to remediate a host with Update Manager, the host is unable to enter maintenance mode.
Which condition is likely preventing the host from entering maintenance mode?
A. A virtual machine on the host has a removable device connected.
B. A virtual machine on the host is configured to use Fault Tolerance.
C. A virtual machine is powered off and cannot be migrated to another host.
D. A virtual machine is configured with a local .vswp file.
Correct Answer: A
Explanation/Reference:
Explanation:
When a host in a cluster is entering maintenance mode, all VMs on that host are vMotioned to another host in the cluster. If the host is not in a cluster, you can configure Update Manager to power off or suspend the VMs or leave them as they are.
ESX/ESXi host updates might require that the host enters maintenance mode before they can be applied. Update Manager puts the ESX/ESXi hosts in maintenance mode before applying these updates.
Update Manager does not remediate hosts on which virtual machines have connected CD/DVD or floppy drives. All removable media drives that are connected to the virtual machines on a host might prevent the host from entering maintenance mode and interrupt remediation. Therefore, you should temporarily disable any removable media devices that might prevent a host from entering maintenance mode.
Incorrect Answers:
B: A VM configured to use Fault Tolerance would not prevent a host going into maintenance mode. Therefore, this answer is incorrect.
C: A powered off VM would not prevent a host going into maintenance mode. Therefore, this answer is incorrect.
D: A VM configured with a local .vswp file would not prevent a host going into maintenance mode. Therefore, this answer is incorrect.
