The correct answer is to migrate to a provisioned IOPS SSD volume. Standard HDD volumes rely on a burst bucket model, where sustained write operations quickly exhaust the burst credits, causing periodic write latency spikes as performance drops to baseline levels. Provisioned IOPS SSD eliminates this bottleneck by guaranteeing consistent, predictable write throughput regardless of workload duration. On the CompTIA Cloud+ CV0-004 exam, this scenario tests your understanding of volume performance characteristics and the critical difference between burst-based and provisioned IOPS models. A common trap is assuming that simply increasing HDD size will fix the issue—while it raises the baseline IOPS, it still operates on a burst model and cannot match the steady performance of provisioned IOPS. Remember the memory tip: “Burst burns out, provisioned persists.” This directly aligns with the search intent of troubleshooting high write latency on HDD by migrating to provisioned IOPS SSD.
CV0-004 Troubleshooting Practice Question
This CV0-004 practice question tests your understanding of troubleshooting. 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 cloud administrator deploys a new application that writes logs to a block storage volume attached to a virtual machine. The application's performance degrades after a few hours. Monitoring shows that the volume's read latency is low, but write latency spikes periodically. The administrator discovers that the volume type is standard HDD. What should the administrator do to improve write performance without changing the application?
Answer the question above first, then reveal the full breakdown to understand why each option is right or wrong.
Correct answer & explanation
✓
Migrate to a volume type with provisioned IOPS (SSD).
Option B is correct because standard HDD has limited burst IOPS, and sustained writes will degrade; provisioned IOPS SSD provides consistent performance. Option A is wrong because increasing HDD size increases baseline IOPS but still limited and burst-based. Option C is wrong because write caching on a data volume is not recommended and may cause data loss. Option D is wrong because object storage is not block-level and may require application changes.
Key principle: Answer the scenario, not the keyword: identify the specific constraint before choosing the most familiar-sounding option.

Why this is correct
Provisioned IOPS SSD provides consistent high IOPS, eliminating write spikes.
Related concept
Read the scenario before looking for a memorised answer.
✗
Increase the volume size to gain higher baseline IOPS.
Why it's wrong here
Increasing size increases baseline IOPS but still uses burst credits which can deplete.
✗
Move the logs to an object storage service.
Why it's wrong here
Object storage is not block-level and may require application changes.
✗
Enable write caching on the volume.
Why it's wrong here
Write caching can cause data loss and is not recommended for data volumes.

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 CV0-004 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.
