Quick Answer
The answer is NFS v4.1 for the best VMware datastore performance. This version delivers superior throughput and lower latency because it introduces pNFS (parallel NFS), which allows multiple clients to access storage directly in parallel, bypassing the single-server bottleneck inherent in NFS v3. Additionally, NFS v4.1 supports sessions for better error recovery and compound operations that reduce network round trips. On the VCP-DCV exam, this question tests your understanding of storage protocol optimization for high-performance workloads; a common trap is assuming NFS v3 is sufficient due to its simplicity, but it lacks these modern performance enhancements. Remember the memory tip: “4.1 is the one for parallel fun”—pNFS is the key differentiator that makes NFS v4.1 the clear choice over v3 or v4.0 for latency-sensitive VMs.
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.
An administrator needs to provision an NFS datastore for VMs that require high performance and low latency. The storage array supports multiple NFS versions. Which NFS version should be selected for the best performance?
Clue words in this question
Noticing these words before you look at the options changes how you read each choice.
Clue: "best"
Why it matters: Signals that multiple options may be partially correct. Choose the option that most directly solves the exact problem described, not the one that sounds most complete.
NFS v4.1
Correct: NFS v4.1 offers improved performance, compound operations, and pNFS support.
NFS v2
Why wrong: Incorrect: NFS v2 is obsolete and unsupported in modern vSphere.
NFS v4.0
Why wrong: Incorrect: NFS v4.0 does not include pNFS; v4.1 is preferred.
NFS v3
Why wrong: Incorrect: NFS v3 is less efficient and lacks features like parallel NFS.
Answer choices
Answer the question above first, then reveal the full breakdown to understand why each option is right or wrong.
Correct answer & explanation
NFS v4.1
NFS version 4.1 provides better performance and security compared to earlier versions, including support for pNFS and sessions. Option B is wrong because NFS v3 is older and has limitations. Option C is wrong because NFS v4.0 lacks some optimizations. Option D is wrong because there is no common NFS v2 in modern environments.
Key principle: Answer the scenario, not the keyword: identify the specific constraint before choosing the most familiar-sounding option.
Answer analysis
For each option: why learners choose it and why it is or isn't the right answer here.
NFS v4.1
Why this is correct
Correct: NFS v4.1 offers improved performance, compound operations, and pNFS support.
Clue confirmation
The clue word "best" in the question point toward this answer.

NFS v2
Why it's wrong here
Incorrect: NFS v2 is obsolete and unsupported in modern vSphere.
NFS v4.0
Why it's wrong here

NFS v3
Why it's wrong here
Incorrect: NFS v3 is less efficient and lacks features like parallel NFS.
Common exam traps
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
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.
Key takeaway
Answer the scenario, not the keyword: identify the specific constraint before choosing the most familiar-sounding option.
Real-world example
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.
