2V0-620 · Question #83

Which two configurable options apply to both virtual machine CPU and memory allocation? (Choose two.)

The correct answer is A. Reservation B. Shares. Reservation and Shares are the two resource allocation controls that exist for both CPU (measured in MHz) and memory (measured in MB/GB) in vSphere.

Why each option

Reservation and Shares are the two resource allocation controls that exist for both CPU (measured in MHz) and memory (measured in MB/GB) in vSphere.

AReservationCorrect

Reservation is configurable for both CPU (in MHz) and memory (in MB/GB), providing a guaranteed minimum amount of each resource that the hypervisor must satisfy before scheduling or running the VM.

BSharesCorrect

Shares set the relative priority of a VM when resource contention occurs and apply to both CPU and memory, determining how leftover resources above reservations are distributed among competing VMs.

CResource Pool

Resource Pool is a vSphere organizational and allocation container for grouping VMs, not a per-VM CPU or memory allocation setting alongside Reservation and Shares.

DReserve All

Reserve All Guest Memory is a memory-only option that pins all VM memory into physical RAM, and has no equivalent counterpart for CPU allocation.
