2V0-620 Question #12: Real Exam Question with Answer & Explanation
The correct answer is C: The CPU reservation should be set to 2 GHz, and the memory reservation should be set to 0MB. vSphere HA slot size is determined by the largest CPU and memory reservations among all powered-on VMs; VM2's 2GHz CPU reservation is the largest, and no VM has a memory reservation, yielding a slot of 2GHz CPU and 0MB memory.

Question
A High Availability (HA) cluster is configured to respond to a given number of host failures. The cluster contains virtual machines configured with these settings: - VM1 has a 1GHz CPU reservation and no Memory reservation - VM2 has a 2GHz CPU reservation and no Memory reservation - VM3 has no CPU reservation and no Memory reservation Given this information, what is the correct slot size for the cluster?
Options
- AThe CPU Reservation should be set to 32MHz and the memory reservation should be set to
- BThe CPU reservation should be set to 1 GHz and the memory reservation should be set to 0MB
- CThe CPU reservation should be set to 2 GHz, and the memory reservation should be set to 0MB
- DThe CPU reservation should be set to 2 GHz, and the memory reservation should be set to
Explanation
vSphere HA slot size is determined by the largest CPU and memory reservations among all powered-on VMs; VM2's 2GHz CPU reservation is the largest, and no VM has a memory reservation, yielding a slot of 2GHz CPU and 0MB memory.
Common mistakes.
- A. 32MHz is the default HA CPU slot size applied only when no virtual machines have CPU reservations; since VM1 (1GHz) and VM2 (2GHz) have explicit reservations, the default is overridden and the largest reservation value must be used instead.
- B. 1GHz corresponds to VM1's CPU reservation, but HA slot sizing always uses the maximum CPU reservation across all powered-on VMs, which is VM2's 2GHz - not the smallest non-zero value.
- D. While this option correctly sets the CPU component to 2GHz, the truncated memory field implies a non-zero memory value, which is not consistent with the given configuration where no VM has any memory reservation.
