A DRS cluster with two ESXi hosts is set to fully automated mode. One host in the cluster is running at 98 percent CPU utilization. The other host is running at 52 percent utilization. Upon analysis, it appears that none of the virtual machines are being migrated from the CPU- constrained host, and no recommendations are being generated.
What are the two most likely causes of the problem? (Choose two.)
A.
The DRS migration threshold setting is too conservative.
B.
The vMotion licenses for the cluster have expired.
C.
Insufficient resources are available to perform vMotion migration operations.
D.
The constrained ESXi host has CPU features that are incompatible with other hosts in the cluster.
The correct answer is A and C.
A – with most conservative migration threshold, DRS will only apply recommendations that must be taken to satisfy cluster constraints like affinity rules and host maintenance.
A is wrong. The problem statement says “no recommendations are being generated”. So the problem is not with the threshold.
A is correct. If the migration threshold is too conservative no recommendations will be generated.
B is nonsense.
C & D are incorrect. If there is CPU incompatibilty, recommendations would still be generated. Same for C.
