VCP-DCV Configure and Manage vSphere Storage Practice Question
This VCP-DCV practice question tests your understanding of configure and manage vsphere storage. Match the stated requirement to the specific cloud service, access model, or configuration option — many options are valid in isolation but not for this scenario. 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 company has a vSphere cluster consisting of 8 ESXi hosts connected to a single Fibre Channel SAN array. They use VMFS6 datastores to store virtual machine files. The storage administrator has scheduled a firmware upgrade for the SAN array that requires a controller reboot. This will cause a temporary loss of connectivity to one LUN (datastore) for approximately 5 minutes. The datastore hosts 15 production VMs, including critical database servers. The cluster has sufficient spare capacity on other datastores, but the VMs are large (each about 200 GB). The vSphere administrator must ensure that these VMs remain available during the upgrade. The cluster has vSphere HA enabled with default settings. What should the administrator do to meet the requirement?
Answer the question above first, then reveal the full breakdown to understand why each option is right or wrong.
Correct answer & explanation
✓
Use Storage vMotion to migrate all VMs on the affected datastores to a healthy datastore before the upgrade.
Using Storage vMotion to live-migrate VMs to a healthy datastore (B) ensures zero downtime during the upgrade. Option A puts hosts into maintenance mode, disrupting VMs. Option C does not protect against storage loss. Option D is for host failure scenarios, not storage disruption.
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.
✓
Use Storage vMotion to migrate all VMs on the affected datastores to a healthy datastore before the upgrade.
Why this is correct
Storage vMotion allows live migration of VM files without downtime, keeping VMs available during the storage upgrade.
Related concept
Read the scenario before looking for a memorised answer.
✗
Configure a vSphere HA admission control policy to reserve resources in case of host failure.
Why it's wrong here
HA admission control is for host failures, not for planned storage maintenance.
✗
Place all ESXi hosts into maintenance mode.
Why it's wrong here
Host maintenance mode will power off VMs, causing downtime, which is not acceptable.
✗
Enable Storage I/O Control on the affected datastore to manage I/O during the upgrade.
Why it's wrong here
SIOC manages I/O shares but does not provide availability during a storage path loss.
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.
