- A
Create a VM storage policy that requires flash-based storage and apply it to the VM.
A storage policy with rule set for flash ensures placement on low-latency storage.
- B
Configure the VM to use multiple paths with Round Robin policy.
Why wrong: Path policy affects throughput, not latency.
- C
Assign a separate VMDK for each critical VM on a dedicated datastore.
Why wrong: This is not a standard practice and does not guarantee low latency.
- D
Enable Storage I/O Control (SIOC) on the datastore.
Why wrong: SIOC manages congestion but does not improve underlying latency.
Question 376 of 521
VCP-DCV vSphere Performance and Scaling Practice Question
This VCP-DCV practice question tests your understanding of vsphere performance and scaling. 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.
An administrator wants to ensure that a critical database VM has consistent low-latency access to its virtual disks. The VM currently resides on a datastore backed by a hybrid array. Which configuration change best meets this requirement?
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
✓
Create a VM storage policy that requires flash-based storage and apply it to the VM.
Option A is correct because creating a VM storage policy that requires flash-based storage and applying it to the VM ensures that the virtual disks are placed on an all-flash datastore, which provides consistent low-latency access. This leverages vSphere Storage Policy-Based Management (SPBM) to enforce placement on flash media, eliminating the variable latency introduced by the HDD tier in a hybrid array.
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.
- ✓
Create a VM storage policy that requires flash-based storage and apply it to the VM.
Why this is correct
A storage policy with rule set for flash ensures placement on low-latency storage.
Related concept
Read the scenario before looking for a memorised answer.
- ✗
Configure the VM to use multiple paths with Round Robin policy.
Why it's wrong here
Path policy affects throughput, not latency.
- ✗
Assign a separate VMDK for each critical VM on a dedicated datastore.
Why it's wrong here
This is not a standard practice and does not guarantee low latency.
- ✗
Enable Storage I/O Control (SIOC) on the datastore.
Why it's wrong here
SIOC manages congestion but does not improve underlying latency.
Common exam traps
Common exam trap: answer the scenario, not the keyword
The trap here is that candidates often confuse I/O management features (SIOC, multipathing) with storage media performance, thinking they can compensate for the inherent latency of HDDs in a hybrid array, but only a flash-based storage policy directly addresses the requirement for consistent low-latency access.
Detailed technical explanation
How to think about this question
Under the hood, SPBM uses storage provider capabilities (e.g., VASA) to advertise flash as a property; the policy enforces placement on datastores where all extents are flash-based. In a hybrid array, even with caching, HDD seeks introduce latency spikes that can exceed 10 ms, whereas all-flash arrays deliver sub-millisecond latency consistently. Real-world scenarios like OLTP databases or real-time transaction systems require this deterministic low latency to avoid timeouts and performance degradation.
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.
TExam Day Tips
- 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.
