Which two statements regarding Distributed Resource Scheduler (DRS) affinity rules are true? (Choose two.)

The correct answer is A. When two VM-VM affinity rules conflict, the older one takes precedence and the newer rule is C. DRS gives higher precedence to preventing violations of anti-affinity rules than violations of. DRS affinity rule conflicts are resolved by keeping the older rule active and disabling the newer one, while anti-affinity rules carry higher enforcement priority than affinity rules.

Why each option

DRS affinity rule conflicts are resolved by keeping the older rule active and disabling the newer one, while anti-affinity rules carry higher enforcement priority than affinity rules.

AWhen two VM-VM affinity rules conflict, the older one takes precedence and the newer rule isCorrect

When two VM-VM affinity rules conflict, vSphere DRS automatically disables the newer rule and keeps the older one active, logging an event so the administrator can investigate and resolve the conflict. This behavior ensures a deterministic outcome rather than leaving placement ambiguous.

BUsing Specify Failover Hosts admission control policy, VM-VM affinity rules are not supported.

VM-VM affinity rules are supported when using the 'Specify Failover Hosts' admission control policy; it is VM-Host affinity rules that can cause complications with certain admission control configurations, not VM-VM rules.

CDRS gives higher precedence to preventing violations of anti-affinity rules than violations ofCorrect

vSphere DRS assigns higher weight to preventing anti-affinity rule violations than affinity rule violations, because separating specified VMs is treated as a stronger constraint for fault tolerance and workload isolation. This means DRS will sacrifice an affinity placement preference before it will place two anti-affinity VMs on the same host.

DIt is not possible to create an affinity rule that conflicts with the other rules being used.

vSphere DRS allows administrators to create affinity rules that conflict with existing ones; it detects the conflict after creation and disables the newer rule automatically rather than blocking rule creation entirely.
