- A
Enable automatic tuning on the secondary.
Can optimize query performance automatically.
- B
Configure the secondary as a readable secondary.
Why wrong: Already readable by default in geo-replication.
- C
Create nonclustered indexes on the secondary replica.
Improves query performance on the secondary.
- D
Force query plans on the primary replica to benefit the secondary.
Why wrong: Query plans are separate on each replica.
- E
Use read-only routing to direct reporting queries to the secondary.
Routes queries to the secondary, offloading the primary.

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. This is a configuration task: choose the command set that satisfies every stated requirement. Small differences — like 'secret' vs 'password' or 'transport input ssh' vs 'all' — change whether the answer is correct. 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 have an Azure SQL Database that is configured with geo-replication. You need to optimize read performance for reporting queries that run on the secondary replica. Which three actions should you take? (Choose three.)
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
✓
Enable automatic tuning on the secondary.
Option A is correct because enabling automatic tuning on the secondary replica allows the database to automatically create, drop, and force index recommendations based on the workload running on that replica. This is particularly beneficial for reporting queries, as the secondary can independently optimize its own index strategy without affecting the primary. Automatic tuning on a readable secondary helps maintain query performance by adapting to the read-heavy workload patterns typical of reporting scenarios.
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
The trap here is that candidates often assume that enabling automatic tuning on the primary automatically benefits the secondary, or that forcing query plans on the primary will propagate to the secondary, when in fact each replica maintains its own query store and plan cache.
Detailed technical explanation
How to think about this question
Under the hood, Azure SQL Database geo-replication uses asynchronous replication, meaning the secondary may have a slight lag. Automatic tuning on the secondary analyzes the query store and index usage patterns specific to the read workload, then applies index recommendations (create, drop, or force) that are independent of the primary. In real-world scenarios, a reporting workload on the secondary might benefit from covering indexes that are not needed on the primary, and automatic tuning can dynamically adjust these without manual intervention.
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.
TExam Day Tips
- 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 cloud solutions architect for a retail company is evaluating services for a new workload. The correct answer here reflects best practice for the specific scenario described — not a general cloud recommendation. Answer the scenario, not the keyword: identify the specific constraint before choosing the most familiar-sounding option. Cloud exam questions reward reading the constraint carefully: the same technology can be right or wrong depending on the use case.
