A cluster's storage remains healthy after a node failure, but some VMs cannot restart because surviving nodes lack RAM. What design issue is indicated?

Choose the single best answer.

A.Live migration can recover memory from the failed host after the event
B.A checkpoint automatically supplies missing physical RAM
C.The quorum witness should contain a copy of each VM's RAM
D.Failover capacity was not sized for the lost node's VM demand

Show the answer and explanation

✓ Correct answer

Failover capacity was not sized for the lost node's VM demand

Surviving-node RAM and compute capacity must accommodate the selected failure tolerance. A witness supplies quorum votes rather than VM memory. Live migration needs a functioning source, and checkpoint storage cannot supply required physical startup RAM.
