1V0-21.20 · Question #2

Which DRS score indicates that the virtual machine (VM) is experiencing severe resource contention?

The correct answer is D. 15%. In vSphere DRS, a lower score indicates higher resource contention, so a 15% score signifies that a virtual machine is experiencing severe resource issues. DRS aims for scores near 100%, reflecting optimal resource distribution and VM performance.

Why each option

In vSphere DRS, a lower score indicates higher resource contention, so a 15% score signifies that a virtual machine is experiencing severe resource issues. DRS aims for scores near 100%, reflecting optimal resource distribution and VM performance.

A50%

A 50% DRS score indicates moderate contention, not severe resource contention.

B95%

A 95% DRS score indicates near-optimal resource utilization and minimal contention, not severe resource contention.

C70%

A 70% DRS score indicates some contention but is not typically considered severe.

D15%Correct

In vSphere Distributed Resource Scheduler (DRS), a lower percentage score indicates a more severe resource contention or imbalance for a VM. A 15% score suggests that the VM is facing significant performance issues due to resource limitations or inefficient placement within the cluster. DRS strives for scores closer to 100%, which represents optimal resource distribution and minimal contention.
