It allows more VMs to run on a host than the physical RAM would normally support (Correct answer)
It accelerates VM performance by transparently compressing memory pages

Correct answer: It allows more VMs to run on a host than the physical RAM would normally support

Memory overcommit increases VM density by allowing the hypervisor to schedule physical RAM among more VMs than could fit if each VM's maximum allocation were fully reserved.

Question 5: Which Nutanix feature enables VMs to be live-migrated away from a node automatically when the node is placed into maintenance mode?

Acropolis Dynamic Scheduling (Correct answer)
VM-Host Affinity
Host Affinity
vMotion

Correct answer: Acropolis Dynamic Scheduling

Acropolis Dynamic Scheduling (ADS) automatically redistributes VMs across available hosts when a node enters maintenance mode or becomes overloaded.

Question 6: What does 'CPU overcommit' mean in the context of AHV virtualization?

Assigning more vCPUs across all VMs than there are physical CPU threads on the host (Correct answer)
Setting hard CPU limits on individual virtual machines
Enabling hyperthreading on the physical host CPU
Pinning specific vCPUs to dedicated physical cores

Correct answer: Assigning more vCPUs across all VMs than there are physical CPU threads on the host

CPU overcommit assigns more total vCPUs across VMs than physical thread count, relying on the hypervisor scheduler to time-share physical cores among competing VMs.

Question 7: How should Nutanix Exam professionals handle difficult conversations?
