2V0-620 · Question #187
An administrator is attempting to power on a virtual machine, but the task is hanging at 95%. What three scenarios best explain why this problem is happening? (Choose three.)
The correct answer is A. A virtual machine question is currently being posed to the administrator. B. Another task for the virtual machine or other component is already in progress. C. The VMware High Availability cluster has insufficient resources to guarantee failover.. A VM power-on task hanging at 95% is most commonly caused by a pending VM question awaiting administrator input, a conflicting in-progress task, or HA admission control blocking the operation due to insufficient failover resources.

Options
- AA virtual machine question is currently being posed to the administrator.
- BAnother task for the virtual machine or other component is already in progress.
- CThe VMware High Availability cluster has insufficient resources to guarantee failover.
- DThe host has lost access to the storage device containing the virtual machine files.
- EThe host is under resource contention and unable to power on the virtual machine.

Why each option
A VM power-on task hanging at 95% is most commonly caused by a pending VM question awaiting administrator input, a conflicting in-progress task, or HA admission control blocking the operation due to insufficient failover resources.
vSphere will pause the power-on sequence at 95% if it needs to ask the administrator a question (for example, whether a VM was moved or copied) and will not proceed until an answer is provided via the vSphere Client.
If another task is already running against the same VM or a component it depends on (such as a snapshot operation or a reconfigure task), the power-on task will be queued or blocked, causing it to appear stuck.
When HA admission control is enabled, vSphere enforces a policy that sufficient cluster resources must be reserved to guarantee failover; if powering on the VM would violate this policy, the task will be blocked at nearly complete.
Loss of storage access would cause the power-on task to fail outright with a storage-related error rather than hanging at 95%, because the VM files would be inaccessible from the start.
Resource contention causes scheduling delays or performance degradation but does not produce a task hang at a specific percentage; the task would either queue, fail with an insufficient resources error, or eventually complete.
