The answer is to configure read-scale replicas, create nonclustered indexes on read-intensive tables, and enable accelerated database recovery. These three actions directly address hyperscale performance optimization by offloading reporting queries from the primary replica, reducing I/O contention through targeted indexing, and minimizing log I/O overhead with accelerated database recovery’s fast rollback and log truncation. On the Microsoft Azure Database Administrator Associate DP-300 exam, this question tests your understanding that Hyperscale’s architecture relies on distributed replicas and efficient indexing rather than traditional resource governance—a common trap is assuming Resource Governor works here, but it is unsupported. Remember that increasing the service tier is a scaling action, not an optimization action, so focus on workload distribution and index design. A useful memory tip is “RIA”: Read-scale replicas, Indexes, Accelerated recovery—the three pillars of Hyperscale tuning.
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 configuring performance optimization for an Azure SQL Database that uses the Hyperscale service tier. The database has heavy read-write workloads. Which THREE actions should you take to optimize performance?
Answer the question above first, then reveal the full breakdown to understand why each option is right or wrong.
Correct answer & explanation
✓
Create nonclustered columnstore indexes on large fact tables.
Options A, C, and D are correct. Hyperscale benefits from nonclustered indexes on read-intensive tables, accelerated database recovery reduces log IO, and read-scale replicas distribute read load. Option B is wrong because Hyperscale does not support resource governor. Option E is wrong because increasing service tier is not an optimization action.
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 nonclustered columnstore indexes on large fact tables.
Why this is correct
Columnstore indexes improve performance for large analytical queries.
Related concept
Read the scenario before looking for a memorised answer.
✗
Configure resource governor to limit CPU usage.
Why it's wrong here
Resource governor is not supported in Hyperscale.
✓
Enable accelerated database recovery (ADR) to reduce transaction log IO.
Why this is correct
ADR reduces log IO, which is beneficial in Hyperscale.
Related concept
Read the scenario before looking for a memorised answer.
✓
Configure read-scale replicas to offload reporting queries.
Why this is correct
Read-scale replicas in Hyperscale can serve read-only workloads.
Related concept
Read the scenario before looking for a memorised answer.
✗
Increase the service tier to Business Critical.
Why it's wrong here
Hyperscale is already the highest tier for scalability; changing is not an optimization.
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.
