VCP VMware Certified Professional 2V0-21.20 Certification 4 — Questions and Answers
Question 1: In vSphere 7, which DRS mode allows administrators to receive migration recommendations without automatic execution?
- Fully Automated
- Partially Automated
- Manual (Correct answer)
- Conservative
Correct answer: Manual
Manual DRS mode generates migration recommendations that administrators must approve and execute manually.
Question 2: Which vSphere 7 feature allows live migration of VMs between vCenter Server instances without shared storage?
- Cross-vCenter vMotion (Correct answer)
- Storage vMotion
- Enhanced vMotion Compatibility (EVC)
- vSphere Replication
Correct answer: Cross-vCenter vMotion
Cross-vCenter vMotion in vSphere 7 supports live migration of VMs across different vCenter Server instances, including without shared storage.
Question 3: What is the purpose of Enhanced vMotion Compatibility (EVC) in a vSphere cluster?
- Accelerate vMotion by compressing memory transfer
- Mask advanced CPU features to ensure vMotion compatibility across different CPU generations (Correct answer)
- Enable vMotion over long-distance WAN links
- Allow vMotion between AMD and Intel hosts in the same cluster
Correct answer: Mask advanced CPU features to ensure vMotion compatibility across different CPU generations
EVC masks host CPU features to a common baseline so VMs can be vMotioned between hosts with different CPU generations.
Question 4: 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 mirrored across 2 hosts, tolerating 1 host failure (Correct answer)
- Data is striped across 3 hosts with parity
- Data is compressed and deduplicated before writing
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 5: Which vSphere 7 tool is used to assess host compliance against a desired configuration baseline?
- vSphere Auto Deploy
- vSphere Update Manager (VUM) / Lifecycle Manager
- vSphere Host Profiles (Correct answer)
- vRealize Configuration Manager
Correct answer: vSphere Host Profiles
vSphere Host Profiles capture and enforce a reference host configuration, allowing compliance checks against all cluster hosts.
Question 6: What is a vSphere 7 resource pool used for?
- Grouping datastores for storage load balancing
- Partitioning CPU and memory resources among VMs in a hierarchy (Correct answer)
- Creating network segments for VM traffic isolation
- Defining backup schedules for groups of VMs
Correct answer: Partitioning CPU and memory resources among VMs in a hierarchy
Resource pools allow hierarchical partitioning of CPU and memory resources with shares, reservations, and limits among groups of VMs.
Question 7: In vSphere 7, which technology enables persistent memory (PMem) to be used as a high-performance storage tier for VMs?
- vSphere Persistent Memory (vPMem) (Correct answer)
- vSAN Direct Configuration
- NVMe over Fabrics (NVMe-oF)
- vFlash Read Cache
Correct answer: vSphere Persistent Memory (vPMem)
vSphere Persistent Memory (vPMem) exposes host NVDIMM/PMem hardware to VMs as either a vPMem disk or a vPMem datastore.
