VCP-VVF Vmware Vsphere Foundation Fundamentals Practice Question
An administrator is configuring a Resource Pool hierarchy in a vSphere Foundation cluster. A child resource pool is set to 'Expandable Reservation'. When does this setting take effect during resource contention?
Answer choices
Why each option matters
Answer the question above first, then reveal the full breakdown to understand why each option is right or wrong.
Correct answer & explanation
✓
When the child resource pool exhausts its own reservation and the parent has unreserved resources available.
Expandable Reservation allows a child resource pool to borrow unreserved resources from its parent resource pool when its own reservation is exhausted.
Answer analysis
Option-by-option breakdown
For each option: why learners choose it and why it is or isn't the right answer here.
- ✗
When the parent resource pool runs out of physical memory and triggers vSphere HA.
Why it's wrong here
HA is triggered by host failures, not resource pool borrowing.
- ✓
When the child resource pool exhausts its own reservation and the parent has unreserved resources available.
Why this is correct
Child pools can borrow from parents when Expandable Reservation is enabled and contention occurs.
- ✗
When virtual machines inside the child pool are powered off.
Why it's wrong here
Powering off VMs releases resources rather than triggering expandable reservations.
- ✗
When Storage DRS initiates a datastore migration.
Why it's wrong here
Storage DRS operates on storage pools, not compute resource pools.
