The answer is a disk failure occurred and components are being rebuilt. This is the most likely cause of vSAN degraded objects in a vSphere cluster because degraded objects specifically indicate that vSAN has detected a component failure—such as from a failed disk or host—and is actively repairing the data through resyncing, where missing or stale components are rebuilt from surviving replicas. On the VMware Certified Professional Data Center Virtualization VCP-DCV exam, this scenario tests your understanding of vSAN health monitoring and the difference between degraded, absent, and rebalancing states; a common trap is confusing degraded objects with network partition issues, which instead produce connectivity alerts. Remember that degraded always means repair is in progress, not that data is lost. A useful memory tip is “Degraded = Disk down, rebuilding now” to distinguish it from absent objects, which indicate a permanent failure.
VCP-DCV Configure and Manage vSphere Storage Practice Question
This VCP-DCV practice question tests your understanding of configure and manage vsphere storage. Examine the command output carefully: the correct answer depends on what the output actually shows, not on general recall alone. 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.
Exhibit
vsan.check.health - Cluster Health
-----------------------------
- vSAN object health: Degraded
- vSAN object repair: In progress
- Resyncing objects: 2
- Resyncing data size: 120.00 GB
- Active rebalance tasks: 0
- Data efficiency: 1.2x (compression + dedup)
Refer to the exhibit. An administrator checks the vSAN cluster health and sees the above output. The cluster has been running for months. What is the most likely cause of the degraded objects?
Clue words in this question
Noticing these words before you look at the options changes how you read each choice.
Clue: "most likely"
Why it matters: Probability qualifier — the question wants the most probable cause or outcome, not a guaranteed one. Eliminate low-probability options.
Answer the question above first, then reveal the full breakdown to understand why each option is right or wrong.
Correct answer & explanation
✓
A disk failure occurred and components are being rebuilt
Degraded objects in vSAN indicate that component failures have occurred and repair is ongoing (resyncing). Option C is correct. Option A (network) would show connectivity issues. Option B (capacity) would show rebalance. Option D (policy change) would cause reconfiguration but not typically degrade.
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.
✓
A disk failure occurred and components are being rebuilt
Why this is correct
Degraded objects with resync indicate repair after failure.
Clue confirmation
The clue word "most likely" in the question point toward this answer.
Related concept
Read the scenario before looking for a memorised answer.
✗
A storage policy was changed to increase redundancy
Why it's wrong here
Policy change would cause reconfiguration but not necessarily degraded state; it would be 'Object reconfiguration'.
✗
A disk group is full and needs capacity expansion
Why it's wrong here
Full disk groups cause rebalance, not necessarily degraded objects.
✗
A network partition between hosts
Why it's wrong here
Network partition would show different symptoms like inaccessible objects.

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.

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.
