2V0-622 Question #180: Real Exam Question with Answer & Explanation

The correct answer is B: Affinity rules are preventing virtual machines from being moved.. A DRS cluster remains unbalanced when VM placement rules or attached local devices block vMotion, preventing DRS from migrating VMs to equalize load.

Question

What are two likely causes for a DRS cluster to become unbalanced? (Choose two.)

Options

  • AMigration threshold is too low.
  • BAffinity rules are preventing virtual machines from being moved.
  • CA device is mounted to a virtual machine preventing vMotion.
  • DMigration cost is too low.

Explanation

A DRS cluster remains unbalanced when VM placement rules or attached local devices block vMotion, preventing DRS from migrating VMs to equalize load.

Common mistakes.

  • A. A lower migration threshold makes DRS more conservative and requires a larger imbalance before recommending migrations, but DRS will still act once that threshold is exceeded - it does not permanently prevent rebalancing.
  • D. Migration cost is not an administrator-configurable DRS parameter; DRS calculates migration cost internally as part of its algorithm and no setting labeled 'migration cost' can be set too low to cause imbalance.
