Which two statements correctly describe VM-Host affinity rules? (Choose two.)
A . When there is more than one VM-Host affinity rule in a vSphere DRS cluster, the rules are applied equally.
B . After creating a VM-Host affinity rule, its ability to function in relation to other rules is predetermined.
C . When there is more than one VM-Host affinity rule in a vSphere DRS cluster, the rules will be ranked.
D . After creating a VM-Host affinity rule, its ability to function in relation to other rules is not checked.
Answer: AD
Explanation:
If you create more than one VM-Host affinity rule, the rules are not ranked, but are applied equally. Be aware that this has implications for how the rules interact. For example, a virtual machine that belongs to two DRS groups, each of which belongs to a different required rule, can run only on hosts that belong to both of the host DRS groups represented in the rules. 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 contacts 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.
