VCP-DCV vSphere Architecture, Products and Solutions Practice Question
An administrator is troubleshooting a performance issue where a VM is not receiving the expected CPU resources. The VM is a member of a resource pool with a CPU Shares value of 2000. The host has two other resource pools: one with 1000 shares and another with 500 shares. All resource pools are competing for CPU. The VM's reservation is set to 2 GHz, and the host has 8 GHz available. What is the minimum CPU allocation the VM is guaranteed?
⚠ Common exam trap
It's easy for candidates to confuse shares with reservations, assuming that a higher share value guarantees more CPU, when in fact only a reservation provides a hard guarantee, and shares only affect the distribution of unused capacity.
Answer choices
Why each option matters
Answer the question above first, then reveal the full breakdown to understand why each option is right or wrong.
Correct answer & explanation
✓
2 GHz
The VM's reservation of 2 GHz guarantees that the host will reserve at least that amount of CPU capacity for the VM, regardless of contention or share values. Shares only affect the distribution of excess resources beyond reservations, not the guaranteed minimum. Since the host has 8 GHz available, the reservation is fully satisfiable, so the VM is guaranteed 2 GHz.
Answer analysis
Option-by-option breakdown
For each option: why learners choose it and why it is or isn't the right answer here.
- ✗
4 GHz (based on share ratio)
Why it's wrong here
Shares determine relative entitlement only during contention, not an absolute guaranteed figure, so 4 GHz is not guaranteed. Deriving a value from the 2000:1000:500 ratio is tempting, but the reservation of 2 GHz is the actual guaranteed minimum.
- ✓
2 GHz
Why this is correct
A reservation is a guaranteed minimum, not a share-based entitlement. The VM's 2 GHz reservation is fully covered by the host's 8 GHz capacity, so regardless of the competing resource pools' shares, the VM is guaranteed at least 2 GHz.
- ✗
8 GHz (all host CPU)
Why it's wrong here
A reservation guarantees only the configured 2 GHz; shares govern contention beyond reservations, so the VM cannot be guaranteed the entire 8 GHz host capacity. Claiming all host CPU is tempting when the VM holds the largest share count, but shares never promise total host resources.
- ✗
0 GHz (no guarantee without reservation)
Why it's wrong here
The VM's explicit 2 GHz reservation guarantees that amount regardless of shares, so zero is wrong. Assuming no reservation exists is tempting because shares alone provide no minimum, but here a reservation is configured, making 2 GHz the guaranteed floor.
