High memory swapping indicates severe memory contention; adding host RAM or migrating the VM to a less-loaded host resolves the root cause.

Question 8: A vSphere administrator needs to ensure that two specific VMs never run on the same ESXi host. Which DRS rule type should be configured?

VM Anti-Affinity rule (Correct answer)
VM Affinity rule
Host Affinity rule
Host Anti-Affinity rule

Correct answer: VM Anti-Affinity rule

A VM Anti-Affinity rule instructs DRS to keep specified VMs on separate ESXi hosts, ensuring they do not run on the same physical server simultaneously.

Question 9: Which ESXi resource management construct sets a guaranteed minimum amount of CPU or memory that a virtual machine will always receive?

Entitlement
Reservation (Correct answer)
Limit
Share

Correct answer: Reservation

A reservation guarantees that a specified amount of CPU (MHz) or memory (MB) is always available to a virtual machine, regardless of host contention.

Question 10: In vSphere 7 vSAN, what is the 'Failures to Tolerate' (FTT) policy setting of 1 with RAID-1 mirroring?

Data is written to 1 host only
Data is compressed and deduplicated before writing
Data is mirrored across 2 hosts, tolerating 1 host failure (Correct answer)
Data is striped across 3 hosts with parity

Correct answer: Data is mirrored across 2 hosts, tolerating 1 host failure

FTT=1 with RAID-1 mirrors VM data across 2 hosts, so the cluster can tolerate the failure of 1 host without data loss.

Question 11: What is the primary function of the vSphere Distributed Resource Scheduler (DRS) imbalance metric?

Measure network bandwidth utilization across hosts
Monitor VM-to-host ratio in the cluster
Track storage latency across datastores
Quantify CPU and memory load imbalance across cluster hosts (Correct answer)

Correct answer: Quantify CPU and memory load imbalance across cluster hosts

Start-to-Finish (SF)
Start-to-Start (SS)
Finish-to-Finish (FF)

Correct answer: Finish-to-Start (FS)

A Finish-to-Start dependency means the predecessor (LUN assignments) must finish before the successor (firewall config) can start.

Question 25: A VM experiences high memory balloon driver activity. What does this indicate about the ESXi host?

The VM has too much memory allocated
The host is experiencing memory contention (Correct answer)
The host has excess free memory
The host's memory hardware is failing

Correct answer: The host is experiencing memory contention

High balloon driver activity indicates the ESXi host is reclaiming memory from VMs due to memory contention on the host.

Question 26: What is the hierarchy of controls in VCP risk management?

PPE first, then administrative, then engineering controls
Elimination, substitution, engineering controls, administrative controls, then PPE (Correct answer)
Insurance, training, documentation, inspection
Assessment, planning, implementation, review

Correct answer: Elimination, substitution, engineering controls, administrative controls, then PPE

The hierarchy prioritizes the most effective controls first: eliminate the hazard entirely, substitute with something safer, use engineering controls, implement administrative measures, and use PPE as the last resort.

Question 27: How do regulations differ from industry standards in VCP practice?

Standards are always stricter than regulations
Regulations apply only to individuals, not organizations
Regulations are legally binding; standards are typically voluntary guidelines (Correct answer)
They are exactly the same thing in all contexts
