Question 23. Which of the following is NOT a valid vMotion network requirement? A) Identical MTU on source and destination VMkernel adapters B) A dedicated VMkernel port for vMotion traffic (recommended) C) Shared storage between hosts is mandatory D) Sufficient bandwidth to handle live migration traffic Answer: C Explanation: vMotion does not require shared storage; it can work with Storage vMotion or local disks. Question 24. In a vSphere environment, the “Admission Control” policy of HA primarily ensures that: A) There are enough resources to restart all VMs in case of a host failure B) Only one VM can be powered on per host at a time C) vMotion migrations are throttled during peak load D) Snapshots are automatically taken before a failover Answer: A Explanation: Admission control reserves capacity so that, after a failure, VMs can be restarted on remaining hosts. Question 25. Which storage protocol uses the Fibre Channel transport and requires a dedicated HBA in the host?
