Expert take: what VCAP-DCV Design really tests
The VMware Certified Advanced Professional – Data Center Virtualization Design (VCAP-DCV Design), from VMware by Broadcom, validates architecting a vSphere 8.x design from customer requirements across conceptual, logical and physical design. The current exam (3V0-21.23) has 60 scenario-based questions in a 145-minute appointment, scored on a 100–500 scale with a passing score of 300, delivered via Pearson VUE. Holding the VCP-DCV is recommended, and the certification is valid for 3 years.
Preparation tips
- Practise turning requirements into conceptual/logical/physical designs.
- Hold the VCP-DCV before attempting the design exam.
- Justify design decisions against availability and performance.
Common mistakes to avoid
- Studying operations instead of design methodology.
- Reading 300 as a percentage — it is a scaled score on 100–500.

Sample VCAP-DCV Design practice questions
5 questions taken from the VCAP-DCV Design mock tests on Wrexa Edge. Try each one, then reveal the answer.
-
Q1. Before remediating a cluster with vLCM, which action shows whether hosts comply with the image without making changes?
- Stage the patches
- Export the image
- Remediate one host
- Run a compliance check
Show answer
Answer: D — Run a compliance check
A compliance check compares each host to the desired image; a remediation pre-check further validates readiness (e.g., maintenance mode, HA).
-
Q2. The architect writes: "Sufficient network bandwidth exists between the two sites for replication," without having validated it. What is this?
- Assumption
- Constraint
- Requirement
- Design decision
Show answer
Answer: A — Assumption
An assumption is something taken as true without proof; each assumption should be validated because it can become a risk.
-
Q3. Which statement about NFS 4.1 datastores compared with NFS 3 in vSphere is correct?
- NFS 4.1 supports Storage I/O Control and Storage DRS while NFS 3 does not at all
- NFS 4.1 supports session trunking (multipathing) and Kerberos authentication
- NFS 4.1 datastores can be formatted with VMFS for block-level access
- NFS 4.1 allows the same share to be mounted as NFS 3 by other hosts safely
Show answer
Answer: B — NFS 4.1 supports session trunking (multipathing) and Kerberos authentication
NFS 4.1 adds multipathing and Kerberos; mounting one share with both NFS versions is unsupported because the locking mechanisms differ.
-
Q4. Two sibling resource pools, A with High shares and B with Normal shares, are under contention. How does CPU get divided between them?
- Equally between pools A and B
- In a 4:1 ratio between pools A and B
- In a 2:1 ratio between pools A and B
- In proportion to the number of VMs in each pool
Show answer
Answer: C — In a 2:1 ratio between pools A and B
High/Normal/Low shares are in a 4:2:1 ratio, so High vs Normal = 2:1; shares are distributed per pool, not per VM.
-
Q5. Why can the HA slot policy become overly conservative?
- Slot size uses the average configured vCPU and configured memory of all VMs in the cluster
- Slot size is fixed at 32 MHz and 100 MB regardless of the VMs running
- Slot size counts powered-off VMs as well as powered-on VMs
- Slot size uses the largest CPU and memory reservations of any powered-on VM
Show answer
Answer: D — Slot size uses the largest CPU and memory reservations of any powered-on VM
One VM with a large reservation inflates the slot size for the whole cluster, reducing available slots; fixed slot size can be set to mitigate.
