A VM is configured with CPU hot-add enabled. What is required for this feature to work?

The VM must be powered off to add CPUs.

The guest OS must support CPU hot-add.

The VM must be on an NFS datastore.

The VM must have at least 4 vCPUs.

A VM is experiencing severe performance degradation. In esxtop, the CPU ready time (%RDY) for the VM's vCPUs averages 25%. The host has 32 logical CPUs, and the VM is configured with 8 vCPUs. The VM's CPU entitlement is 4 GHz, and the host's CPU speed is 2.5 GHz. What is the most likely cause of the high ready time?

The VM's CPU limit is set too low, throttling its CPU usage.

The VM's memory is ballooned, forcing CPU overhead for memory reclamation.

The VM's CPU shares are set too low relative to other VMs on the host.

The VM is over-provisioned with vCPUs, causing scheduling contention on the host.

A VM's guest OS is unresponsive, and the administrator suspects a kernel panic. Which log file should be examined first to confirm the guest OS issue?

The VM's vmware.log file on the datastore.

The vCenter Server's vpxd.log file.

The guest OS's system log (e.g., /var/log/messages on Linux).

A VM with an RDM disk is failing to power on with the error: 'Cannot open the disk or one of the snapshot disks it depends on.' The RDM's LUN is visible on the host. What is the most likely cause?

The LUN is not formatted with a supported file system.

The VM's SCSI controller is not configured for RDM support.

The RDM's mapping file (VMDK) is missing or corrupted.

The VM's VMware Tools is not installed, preventing RDM access.

A VM is missing a virtual disk that was previously present. Which location should you check first to verify the disk is still attached?
