- A
Enable Service Broker in Azure SQL Database by setting ENABLE_BROKER.
Why wrong: Service Broker is not supported in Azure SQL Database.
- B
Scale up the database to a higher service tier to improve Service Broker performance.
Why wrong: Scaling up does not enable a disabled feature.
- C
Replace Service Broker with Azure Queue Storage or Event Grid.
Azure SQL Database does not support Service Broker; use PaaS messaging services.
- D
Configure Service Broker to use external activation via Azure Functions.
Why wrong: External activation is not supported because Service Broker itself is not available.

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 migrating an on-premises SQL Server database to Azure SQL Database. The database uses Service Broker for asynchronous messaging. After migration, you notice that performance is degraded. What should you do to optimize?
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
✓
Replace Service Broker with Azure Queue Storage or Event Grid.
Service Broker is not fully supported in Azure SQL Database; it has performance and reliability limitations. The recommended approach for asynchronous messaging is to use Azure-native services like Queue Storage or Event Grid. Therefore, the correct action is to replace Service Broker (Option C). Option A is incorrect because while ENABLE_BROKER can be used, it is not recommended for production due to poor performance. Option B is incorrect because scaling up does not resolve the fundamental feature incompatibility. Option D is incorrect because external activation via Azure Functions does not address the root cause and adds complexity.
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.
