- A
The PSP should be changed to VMW_PSP_MRU to use both paths.
Why wrong: MRU uses only one path; it would not help utilize standby paths.
- B
The array is not properly configured to present both paths as active/optimized.
For RR to use multiple paths, the array must set both paths as active/optimized. One standby path will not receive I/O.
- C
The claim rule should have used VMW_SATP_DEFAULT_AA instead.
Why wrong: VMW_SATP_DEFAULT_AA is for non-ALUA arrays; using it would ignore ALUA states and might mark both paths active, but it's not correct for an ALUA array.
- D
The TPGS option should be disabled to force both paths active.
Why wrong: Disabling TPGS would cause the SATP to treat paths as active/active, which could cause errors if the array enforces asymmetric access.
ALUA Path Issue with Round Robin — Only One Active Path
This VCP-DCV practice question tests your understanding of configure and manage vsphere storage. This is a configuration task: choose the command set that satisfies every stated requirement. Small differences — like 'secret' vs 'password' or 'transport input ssh' vs 'all' — change whether the answer is correct. 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.
Refer to the exhibit. An administrator configures a claim rule to use VMW_SATP_ALUA with VMW_PSP_RR and TPGS enabled. After applying the rule, the device shows one active and one standby path. However, the administrator notices that I/O is only sent to the active path. What is the most likely reason?

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 array is not properly configured to present both paths as active/optimized.
With ALUA, paths have asymmetric access states. The PSP RR distributes I/O across all active paths. If only one path is active and the other is standby, RR will only use the active path. The standby path is not used for I/O. To utilize both paths, the array must present both paths as active/optimized. This is expected behavior for ALUA with one standby path.
Key principle: Answer the scenario, not the keyword: identify the specific constraint before choosing the most familiar-sounding option.

For each option: why learners choose it and why it is or isn't the right answer here.
- ✗
The PSP should be changed to VMW_PSP_MRU to use both paths.
Why it's wrong here
MRU uses only one path; it would not help utilize standby paths.
- ✓
The array is not properly configured to present both paths as active/optimized.
Why this is correct
For RR to use multiple paths, the array must set both paths as active/optimized. One standby path will not receive I/O.

The claim rule should have used VMW_SATP_DEFAULT_AA instead.
Why it's wrong here
VMW_SATP_DEFAULT_AA is for non-ALUA arrays; using it would ignore ALUA states and might mark both paths active, but it's not correct for an ALUA array.
- ✗
The TPGS option should be disabled to force both paths active.
Why it's wrong here
Disabling TPGS would cause the SATP to treat paths as active/active, which could cause errors if the array enforces asymmetric access.
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.
