The answer is to enable Accelerated Database Recovery, increase the log rate limit, and use smaller log writes. These three actions directly target the bottlenecks in Hyperscale’s distributed architecture: Accelerated Database Recovery reduces log amplification by minimizing version store overhead, a higher log rate limit allows more transactions per second to be committed, and smaller log writes decrease I/O latency per transaction. On the DP-300 exam, this question tests your understanding that Hyperscale separates compute from storage, so traditional fixes like scaling to Business Critical are invalid, and read scale-out only helps queries, not writes. A common trap is confusing log rate limits with storage size—remember, Hyperscale’s log throughput is capped by the service objective, not disk space. For a memory tip, think “LAR” for Log rate, Accelerated recovery, and Reduced write size.
DP-300 Practice Question: Monitor, configure, and optimize database resources
This DP-300 practice question tests your understanding of monitor, configure, and optimize database resources. 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.
You are optimizing an Azure SQL Database that uses the Hyperscale service tier. You need to identify which three actions can improve write performance. Which THREE should you select?
Answer the question above first, then reveal the full breakdown to understand why each option is right or wrong.
Correct answer & explanation
✓
Use smaller log writes
Option B is correct: Increasing log rate limit improves log throughput. Option C is correct: Using smaller log writes reduces latency. Option D is correct: Enabling Accelerated Database Recovery reduces log amplification. Option A is incorrect: Increasing service tier to Business Critical does not apply to Hyperscale. Option E is incorrect: Read scale-out does not improve write performance.
Key principle: Answer the scenario, not the keyword: identify the specific constraint before choosing the most familiar-sounding option.

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 media company stores terabytes of video archives that are accessed once a year for audit purposes. Moving these objects to a cold storage tier (Azure Archive, S3 Glacier, or Google Nearline) costs a fraction of hot storage. Questions like this test whether you understand storage tiers, access frequency tradeoffs, and retrieval latency requirements.
