VCP-VVF IT Architectures Technologies Standards Practice Question
An administrator is designing a vSphere Foundation 9.0 cluster and wants to optimize memory resource utilization across virtual machines. Which memory management technique reclaims idle memory from running VMs by temporarily reallocating it to VMs experiencing memory pressure?
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
✓
Memory ballooning via the VMware Tools balloon driver (vmmemctl).
Transparent Page Sharing (TPS) and memory ballooning are classic hypervisor memory reclamation techniques; ballooning actively reclaims allocated guest memory.
Answer analysis
Option-by-option breakdown
For each option: why learners choose it and why it is or isn't the right answer here.
- ✓
Memory ballooning via the VMware Tools balloon driver (vmmemctl).
Why this is correct
Correct. The balloon driver reclaims guest memory under pressure and gives it to the hypervisor pool.
- ✗
Enabling Fibre Channel multipathing round-robin policies.
Why it's wrong here
Multipathing manages storage I/O, not host memory reclamation.
- ✗
Upgrading physical RAM modules without rebooting the ESXi host.
Why it's wrong here
RAM upgrades require physical hardware installation.
- ✗
Forcibly killing guest operating system background services using remote SSH commands.
Why it's wrong here
Killing guest services is a manual, disruptive process not performed by the hypervisor memory manager.
