2V0-622D Question #252: Real Exam Question with Answer & Explanation
The correct answer is A: DRS will avoid placing virtual machines on hosts that are considered network saturated.. vSphere 6.5 DRS includes network-aware load balancing, so when evacuating a host it will avoid placing VMs on hosts already experiencing high network bandwidth saturation.
Section 7 – Administer and Analyze vSphere 6.5 Performance
Question
In a vSphere 6.5 cluster of 6 nodes, memory usage is very high on host1 and host2, and network bandwidth usage is very high on host3 and host4. The administrator needs to place host1 into maintenance mode. How will DRS relocate virtual machines?
Options
- ADRS will avoid placing virtual machines on hosts that are considered network saturated.
- BIf DRS "VM Distribution" has been applied, virtual machines will be evenly distributed across the
- CIf "Memory metric for load balancing" has been disabled, virtual machines will be moved solely
- DVirtual machines will be moved only if host affinity rules have been configured.
Explanation
vSphere 6.5 DRS includes network-aware load balancing, so when evacuating a host it will avoid placing VMs on hosts already experiencing high network bandwidth saturation.
Common mistakes.
- B. The VM Distribution setting spreads VMs evenly by count across hosts but does not factor in the specific resource saturation states of host3 and host4 when choosing migration targets.
- C. Disabling the memory metric causes DRS to rely primarily on CPU utilization for balancing decisions, which would ignore both memory and network conditions and could still place VMs on the saturated hosts.
- D. Host affinity rules constrain where specific VMs may run but do not by themselves drive or prevent DRS from relocating VMs during a maintenance mode evacuation.
