The answer is network connectivity between hosts for management traffic and a shared storage solution, as these are the foundational prerequisites for any vSphere cluster running both vSphere HA and DRS. vSphere HA relies on management network connectivity to enable heartbeat exchanges between hosts and to elect a master node, while DRS requires shared storage to allow live migration of virtual machines via vMotion. On the VMware Certified Professional Data Center Virtualization VCP-DCV exam, this concept tests your understanding that a single vCenter Server is sufficient to manage both services, and that clock synchronization is critical for HA master election and DRS recommendations—though it is not a strict prerequisite. A common trap is assuming multiple vCenter Servers are needed, but the exam emphasizes that one vCenter can handle the cluster. Remember the memory tip: “HA needs a heartbeat, DRS needs a shared cart”—management network for heartbeats, shared storage for vMotion.
VCP-DCV vSphere Architecture, Products and Solutions Practice Question
This VCP-DCV practice question tests your understanding of vsphere architecture, products and solutions. Read the scenario carefully and evaluate each option against the stated constraints before committing to an answer. After answering, compare your reasoning against the explanation and wrong-answer breakdown below. Once you have made your selection, read the full explanation to reinforce the concept and understand why each distractor is designed to mislead on exam day.
Which two of the following are required to deploy a vSphere cluster with vSphere HA and DRS? (Choose two.)
Answer the question above first, then reveal the full breakdown to understand why each option is right or wrong.
Correct answer & explanation
✓
Clock synchronization across all hosts (NTP)
Options B and E are correct. Multiple vCenter Servers are not required; one vCenter can manage HA/DRS. Options D is optional. Clock synchronization is critical for HA master election and DRS recommendations.
Key principle: Answer the scenario, not the keyword: identify the specific constraint before choosing the most familiar-sounding option.
Answer analysis
Option-by-option breakdown
For each option: why learners choose it and why it is or isn't the right answer here.
✓
Clock synchronization across all hosts (NTP)
Why this is correct
HA and DRS require synchronized time for proper operation.
Related concept
Read the scenario before looking for a memorised answer.
✗
A minimum of two vCenter Server instances
Why it's wrong here
Only one vCenter Server is required for a cluster.
✓
Network connectivity between hosts for management traffic
Why this is correct
HA and DRS need management network communication.

Shared storage accessible by all hosts in the cluster
Why it's wrong here
HA/DRS can work without shared storage (e.g., vSAN is shared, but not required).
Common exam traps
Common exam trap: answer the scenario, not the keyword
Many certification questions include familiar terms but test a specific constraint. Read the exact wording before choosing an answer that is generally true but wrong for this case.
Detailed technical explanation
How to think about this question
This question should be treated as a scenario, not a definition check. Identify the problem, the constraint and the best action. Then compare each option against those facts.
KKey Concepts to Remember
Read the scenario before looking for a memorised answer.
Find the constraint that changes the correct option.
Eliminate answers that are true in general but not in this case.
Use explanations to understand the rule behind the answer.
TExam Day Tips
→Underline the problem statement mentally.
→Watch for words such as best, first, most likely and least administrative effort.
→Review why wrong options are wrong, not only why the correct option is correct.
Key takeaway
Answer the scenario, not the keyword: identify the specific constraint before choosing the most familiar-sounding option.
Real-world example
How this comes up in practice
A practitioner preparing for the VCP-DCV exam encounters this exact type of scenario on the job. The correct answer here is not the most general option — it is the best answer for the specific constraint described. Answer the scenario, not the keyword: identify the specific constraint before choosing the most familiar-sounding option. Real exam questions reward reading the full scenario before eliminating options, because the constraint defines which answer fits.
