DP-300 Practice Question: Monitor, configure, and optimize database resources
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 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
✓
Use smaller log writes
Using smaller log writes reduces log write latency, which improves write performance in Hyperscale. Option B is correct: Increasing the log rate limit allows higher log throughput, directly enhancing write performance. Option E is correct: Enabling Accelerated Database Recovery reduces log amplification and improves log write efficiency, benefiting write performance. Option C is incorrect: The Hyperscale service tier is distinct from Business Critical; moving to Business Critical does not apply to Hyperscale. Option D is incorrect: Read scale-out improves read performance, not write performance.
