VCP VMware Certified Professional 4 — Questions and Answers
Question 1: Which VMware technology enables live migration of running VMs across vCenter Server instances in different SSO domains?
- vSphere vMotion
- vSphere Cross vCenter vMotion (Correct answer)
- VMware HCX
- vSphere Replication
Correct answer: vSphere Cross vCenter vMotion
Cross vCenter vMotion allows live migration of running VMs between vCenter Server instances, even across different SSO domains.
Question 2: In vSAN, what is the 'Failures to Tolerate' (FTT) storage policy setting used for?
- Defining maximum VM snapshot count
- Specifying how many host or disk failures a VM's storage can withstand (Correct answer)
- Setting the maximum IOPS for a VM
- Controlling datastore deduplication ratio
Correct answer: Specifying how many host or disk failures a VM's storage can withstand
FTT defines the number of host or disk failures that vSAN can tolerate while keeping a VM's data accessible, controlling how many data copies are maintained.
Question 3: Which ESXi command-line tool is used to manage ESXi configuration and perform troubleshooting tasks from the ESXi Shell?
- vmrun
- esxcfg-nics
- esxcli (Correct answer)
- vmkfstools
Correct answer: esxcli
esxcli is the primary command-line interface for configuring and troubleshooting ESXi hosts directly from the ESXi Shell or remotely.
Question 4: What does the vSphere 'Proactive HA' feature do when a hardware health sensor on a host degrades?
- Immediately powers off the host
- Evacuates VMs from the degraded host before it fails completely (Correct answer)
- Triggers a full cluster rebalance via DRS
- Sends an alert but takes no automated action
Correct answer: Evacuates VMs from the degraded host before it fails completely
Proactive HA integrates with hardware health monitoring to evacuate VMs from a host showing degraded hardware signals before a full failure occurs.
Question 5: Which network security policy setting on a vSphere Standard Switch prevents a VM from capturing traffic intended for other VMs on the same switch?
- Forged Transmits
- MAC Address Changes
- Promiscuous Mode (Correct answer)
- VLAN Trunking
Correct answer: Promiscuous Mode
Setting Promiscuous Mode to Reject prevents a VM's network adapter from receiving traffic not addressed to its own MAC address, blocking passive network sniffing.
Question 6: When using vSphere Fault Tolerance (FT), which vMotion type continuously synchronizes the state of the primary VM to its secondary?
- Storage vMotion
- vSphere Replication
- Fast Checkpointing
- vLockstep / Continuous vMotion (Correct answer)
Correct answer: vLockstep / Continuous vMotion
vSphere FT uses a continuous synchronization mechanism (based on vLockstep/Continuous vMotion) to keep the secondary VM in lockstep with the primary at all times.
Question 7: What is the purpose of the VMware vSphere API for Storage Awareness (VASA)?
- To enable VMware Tools installation on storage appliances
- To allow storage arrays to expose capabilities to vCenter for policy-based management (Correct answer)
- To compress VMDK files on NFS datastores
- To replicate VMs to secondary storage locations
Correct answer: To allow storage arrays to expose capabilities to vCenter for policy-based management
VASA allows storage vendors to surface array capabilities (like thin provisioning and replication support) to vCenter, enabling VM Storage Policies to leverage those features.
