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.
C is not correct, there is really no priority between any affinity rules.
B it is, https://pubs.vmware.com/vsphere-50/index.jsp?topic=%2Fcom.vmware.vsphere.avail.doc_50%2FGUID-C4F5F9EE-4235-4151-BEBE-FCB2A752407B.html
If you use the Specify Failover Hosts admission control policy and designate multiple failover hosts, DRS does not load balance failover hosts and VM-VM affinity rules are not supported
A,C are correct. See https://docs.vmware.com/en/VMware-vSphere/5.5/com.vmware.vsphere.resmgmt.doc/GUID-69C738B6-5FC8-4189-9CB5-DD90A5A05979.html
If two VM-VM affinity rules are in conflict, you cannot enable both. For example, if one rule keeps two
virtual machines together and another rule keeps the same two virtual machines apart, you cannot enable
both rules. Select one of the rules to apply and disable or remove the conflicting rule.
When two VM-VM 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 gives higher precedence to
preventing violations of anti-affinity rules than violations of affinity rules.
