VCP Data Center Virtualization 3 — Questions and Answers
Question 1: What is the minimum number of ESXi hosts required to form a vSAN cluster?
- 2
- 3 (Correct answer)
- 4
- 6
Correct answer: 3
A standard vSAN cluster requires a minimum of 3 ESXi hosts to maintain quorum and data availability with FTT=1.
Question 2: Which vSphere DRS automation level requires administrator approval before migrating virtual machines?
- Fully Automated
- Manual (Correct answer)
- Partially Automated
- Disabled
Correct answer: Manual
In Manual mode, DRS generates migration recommendations but requires an administrator to review and apply each one.
Question 3: What technology does VMware use to allow a VM's memory pages to be shared across multiple VMs running identical content?
- Ballooning
- Transparent Page Sharing (TPS) (Correct answer)
- Memory Compression
- Swap to Host Cache
Correct answer: Transparent Page Sharing (TPS)
Transparent Page Sharing identifies identical memory pages across VMs and maps them to a single physical page, reducing overall memory consumption.
Question 4: In vSphere, what is an OVF template used for?
- Configuring network distributed switches
- Packaging and deploying virtual machines or vApps in a portable format (Correct answer)
- Backing up VMFS datastores
- Encrypting virtual machine disk files
Correct answer: Packaging and deploying virtual machines or vApps in a portable format
OVF (Open Virtualization Format) is an open standard for packaging and distributing virtual machines and vApps in a vendor-neutral format.
Question 5: Which ESXi storage adapter type is used for iSCSI connectivity?
- FC HBA
- Software iSCSI adapter or hardware iSCSI HBA (Correct answer)
- NVMe-oF adapter
- SCSI parallel adapter
Correct answer: Software iSCSI adapter or hardware iSCSI HBA
ESXi supports both software iSCSI (using standard NICs) and hardware iSCSI HBAs for connecting to iSCSI storage arrays.
Question 6: What is the purpose of a vmkernel port (VMkernel adapter) in ESXi?
- To provide network access for virtual machines
- To handle ESXi management, vMotion, storage, and other host-level traffic (Correct answer)
- To bridge physical and virtual networks
- To connect to external physical switches
Correct answer: To handle ESXi management, vMotion, storage, and other host-level traffic
VMkernel adapters handle host-level traffic such as management, vMotion, vSAN, fault tolerance, and NFS storage connections.
Question 7: Which vSphere feature enables a VM to have its state continuously replicated to a secondary VM on another host, providing zero-RPO protection?
- vSphere Replication
- vSphere Fault Tolerance (FT) (Correct answer)
- vSphere High Availability
- Site Recovery Manager
Correct answer: vSphere Fault Tolerance (FT)
vSphere Fault Tolerance maintains a live shadow VM on a secondary host that mirrors every CPU instruction, providing zero data loss on host failure.
