Question 6: Which two statements regarding Distributed Resource Scheduler (DRS) affinity rules are true?(Choose two.)
A. When two VM-VM affinity rules conflict, the older one takes precedence and the newer rule is
disabled.
B. Using Specify Failover Hosts admission control policy, VM-VM affinity rules are not supported.
C. DRS gives higher precedence to preventing violations of anti-affinity rules than violations of affinity
rules.
D. It is not possible to create an affinity rule that conflicts with the other rules being used.
Correct Answer: A,C
Explanation:
When you create a VM-Host affinity rule, its ability to function in relation to other rules is not
checked. So, it is possible for you to create a rule that conflicts with the other rules you are using.
When two VM-Host affinity rules conflict, the older one takes precedence and the newer rule is
disabled. DRS only tries to satisfy enabled rules and disabled rules are ignored. DRS, vSphere HA, and
vSphere DPM never take any action that results in the violation of required affinity rules (those
where the virtual machine DRS group 'must run on' or 'must not run on' the host DRS group).
Accordingly, you should exercise caution when using this type of rule because of its potential to
adversely affect the functioning of the cluster. If improperly used, required VM-Host affinity rules can
fragment the cluster and inhibit the proper functioning of DRS, vSphere HA, and vSphere DPM.
