Question 3. Which virtual machine component defines the amount of CPU processing power allocated to a VM? A) vRAM B) vCPU C) Virtual NIC D) Virtual Disk Answer: B Explanation: The vCPU (virtual CPU) represents a logical processor that the hypervisor schedules onto physical CPU cores. Question 4.

Answer: C Explanation: NFS datastores use the NFS protocol to provide file‑level storage for VMs. Question 21. What does the “Ready” metric for a VM’s CPU indicate? A) Time the VM spent executing instructions on the physical CPU. B) Time the VM was waiting for CPU resources to be scheduled. C) Time spent in the guest OS idle loop. D) Time the VM was paused by the administrator. Answer: B Explanation: “Ready” time measures how long a VM’s vCPU was ready to run but could not be scheduled onto a physical CPU. Question 22. Which of the following is a benefit of using VM templates over cloning from a powered‑on VM? A) Templates automatically include guest OS patches. B) Templates guarantee 100 % storage deduplication. C) Templates provide a consistent baseline and can be deployed faster because they are pre‑configured. D) Templates prevent any future changes to the VM configuration. Answer: C
Exam
Explanation: Templates are pre‑configured images that ensure consistency and speed up provisioning. Question 23. In a vSphere Distributed Resource Scheduler (DRS) cluster, what does the “Automation” mode do? A) It disables all DRS actions. B) It allows DRS to automatically migrate VMs based on load without user approval. C) It only recommends migrations but requires manual confirmation.

Which of the following is a key difference between “snapshot” and “clone” in virtualization? A) Snapshots are read‑only; clones are read‑write. B) Snapshots capture the VM’s state at a point in time, while clones create a full, independent copy of the VM. C) Clones can only be created from powered‑off VMs. D) Snapshots automatically delete after 24 hours. Answer: B Explanation: Snapshots preserve a VM’s current state (including memory) and rely on delta disks, whereas clones generate a new, standalone VM. Question 37.
