What are three reasons why a virtual machine might fail to power on? (Choose three.)

Question

Options

• AThe virtual machine is running on an ESXi host which has an expired license.
• BThe virtual machine is running on a datastore which has insufficient disk space for the .vswp file.
• CThe virtual machine is in a cluster with vSphere HA Admission control enabled.
• DThe virtual machine has a disconnected network adapter.
• EThe virtual machine does not have a Virtual Hard Disk assigned.

Explanation

Three valid reasons: (A) An expired ESXi host license restricts functionality including the ability to power on VMs - this is a hard enforcement by the hypervisor. (B) Insufficient datastore space to create the VM's swap file (.vswp) - vSphere creates a swap file equal to the VM's configured memory when it powers on; if the datastore is full, power-on fails. (C) vSphere HA Admission Control reserves cluster capacity to guarantee failover resources; if powering on a VM would violate those reserved resources, HA blocks the power-on operation. Option D (disconnected NIC) does not prevent power-on - the VM starts and the adapter simply has no connectivity. Option E (no virtual hard disk) does not prevent power-on either - the VM will start but fail to boot an OS, which is a different condition.
