- A
The network latency between sites must be less than 5 ms round-trip.
Latency must be under 5 ms round-trip to ensure acceptable performance for vSAN synchronization traffic.
- B
The witness host must be placed at the primary site.
Why wrong: The witness host must be placed at a third, independent site to avoid a single point of failure and maintain quorum.
- C
Each site must have a minimum of two hosts.
Each site requires at least two hosts to provide redundancy and support the stretched cluster configuration.
- D
All hosts must be configured with a single network adapter for vSAN traffic.
Why wrong: Hosts can use multiple network adapters for vSAN traffic for redundancy and performance; a single adapter is not required.
- E
A vSAN stretched cluster requires a minimum of four fault domains.
Why wrong: A vSAN stretched cluster uses two fault domains (one per site) and a separate witness host, not four fault domains.
Quick Answer
The correct answer is that each site must have a minimum of two hosts, and network latency between sites must be less than 5 ms round-trip. A vSAN stretched cluster creates two fault domains, one per site, and each fault domain requires at least two hosts to maintain quorum and provide redundancy if a single host fails; the witness host resides at a third site to break ties. On the VCP-DCV exam, this question tests your understanding of the architectural constraints for disaster avoidance, often appearing as a multiple-select item where common traps include assuming the witness can be at the primary site or that four fault domains are needed. Remember the key thresholds: two hosts per site and sub-5 ms latency—think of it as “two sites, two hosts, five milliseconds” to avoid confusing the witness placement or fault domain count.
VCP-DCV Configure and Manage vSphere Storage Practice Question
This VCP-DCV practice question tests your understanding of configure and manage vsphere storage. 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.
A storage administrator is planning a vSAN stretched cluster for a remote office. The cluster must support stretching across two sites for disaster avoidance. Which two prerequisites must be met? (Choose two.)
Answer choices
Why each option matters
Answer the question above first, then reveal the full breakdown to understand why each option is right or wrong.
Correct answer & explanation
The network latency between sites must be less than 5 ms round-trip.
Correct options A and D: Each site must have a minimum of two hosts (A) and network latency between sites must be less than 5 ms round-trip (D). Option B is incorrect because the witness host must be placed at a third site, not the primary. Option C is incorrect because a vSAN stretched cluster uses two fault domains (one per site) plus a witness, not four. Option E is incorrect because hosts can use multiple network adapters for vSAN traffic.
Key principle: Answer the scenario, not the keyword: identify the specific constraint before choosing the most familiar-sounding option.

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.
