Which two statements are true for Predictive DRS? (Choose two.)
A.
It balances resource utilization for virtual machines with unpredictable utilization patterns.
B.
It integrates DRS with vRealize Operations Manager to balance workloads for virtual machines before
resource utilization spikes occur.
C.
It balances resource utilization based on a threshold’s algorithm that runs each night.
D.
It determines the best placement and balance of virtual machines based on a threshold’s algorithm that
runs each night in vCenter Server 6.5 Database.

BC is corect.
vRealize Operations Manager runs its dynamic thresholds algorithm nightly against the VMs on which it collects data. These dynamic thresholds create forecasted metrics for the future utilization of the VMs.
The metrics are then passed to vSphere DRS to determine the best placement and balance of VMs before resource utilization spikes occur.
Predictive DRS helps prevent resource contention on hosts that run VMs with predictable utilization patterns.

By the way, part of new 140Q VMWare 2V0-622D dumps are available here:

Why C & not D? They are very similar, kind of tricky. Placement & balance on D seems right to me. I don’t know if it actually runs “in the database” though?

Algorithm runs on vRealize Operations Manager, not vCenter DB. So D is wrong.

According to this document:
https://blogs.vmware.com/management/2016/11/predictive-drs.html
The actual threshold that is used is the Dynamic Threshold that ‘lives’ on vRealize Operations Manager. vROPS data is not stored in the vCenter Server Database (it uses an Apache Cassandra database). So D would then be incorrect, leaving C.
