VMware VCP-DCV (2V0-21.23) - Exam Strategy

Format reminder

  • 70 questions, 135 minutes
  • Pass mark: 300 / 500 (scaled)
  • Multiple choice + multiple response
  • Tests vSphere 8.x administration

Top traps

  1. vSphere HA vs FT vs DRS:
  2. HA: restart on host failure (downtime = boot time)
  3. FT: zero-downtime per-VM mirror (limited to 8 vCPU per FT VM)

  4. DRS: load balance across hosts (uses vMotion) Don't confuse.

  5. vSAN policies: per-VM, define FTT (1, 2, 3) + FTM (mirror RAID-1 vs erasure coding RAID-⅚) + IOPS + performance reservations. Erasure coding requires more hosts (RAID-5 needs 4+, RAID-6 needs 6+).

  6. vSS vs vDS: vSS is per-host, vDS is cluster-wide. vDS provides advanced features (Network I/O Control, port mirroring, LACP, NetFlow). VCP-DCV expects vDS in modern designs.

  7. Storage protocols: VMFS (block, on iSCSI/FC), NFS (v3 vs v4.1), vSAN (HCI), vVols. Each has tradeoffs.

  8. vMotion variants:

  9. vMotion: compute, same datastore, same vCenter
  10. Storage vMotion: change datastore, same host
  11. Cross-vCenter vMotion: across vCenter
  12. Cross-cloud vMotion: with VMware Cloud

  13. Long Distance vMotion: RTT up to 150ms

  14. DRS automation levels: Manual, Partially Automated, Fully Automated. Affinity vs anti-affinity rules.

  15. Resource pools: hierarchical, shares + reservations + limits. Don't over-nest.

  16. Permissions model: roles (predefined or custom) + inventory hierarchy. Permissions inherit; can be overridden per object.

  17. vCenter HA: 3-node cluster (active + passive + witness), distinct from vSphere HA.

  18. Lifecycle Manager (vLCM): declarative image-based, replaces VUM. Cluster-level desired-state images.

High-yield topics easy to miss

  • vSphere Lifecycle Manager image vs baseline
  • Content Library (templates + ISOs across vCenters)
  • vSphere with Tanzu (Kubernetes integrated into vSphere)
  • vSphere Trust Authority (key management for encrypted VMs)
  • VM encryption with key management server
  • Distributed Resource Scheduler (DRS) Affinity Rules + DRS Cluster Cost-based selection
  • Predictive DRS (uses vRealize Operations)
  • vSphere Replication for DR
  • vCenter REST API + PowerCLI for automation

Time management

135 / 70 = ~2 min/question.

When stuck

  1. Match the use case to the right vSphere feature (HA / FT / DRS / vMotion).
  2. Default to the modern recommendation - vDS over vSS, vLCM over VUM, vSAN over traditional SAN where appropriate.
  3. Eliminate "manual workaround" when a vSphere feature handles it natively.

Day-of logistics

135 min, 70 questions. Pearson VUE.

After

Pass: Cert valid 2 years (recertification path). VCAP and VCDX as advanced steps.

Fail: Most failures are on Storage (vSAN policies) or Networking (vDS / port groups). Build a home lab if you don't have access to vSphere through work.

VCP-DCV patterns

  • "Restart VMs on host failure" = vSphere HA + restart priority
  • "Zero-downtime per-VM" = Fault Tolerance (max 8 vCPU)
  • "Load balance across hosts" = DRS
  • "Move VM compute + storage" = Combined vMotion + Storage vMotion
  • "Cluster-level networking" = vDS
  • "Per-VM storage policy" = vSAN storage policy with FTT + FTM
  • "vCenter availability" = vCenter HA (active+passive+witness)
  • "Cluster lifecycle" = vSphere Lifecycle Manager images
  • "Encrypted VMs" = VM Encryption + KMS / vSphere Trust Authority
  • "K8s on vSphere" = vSphere with Tanzu
