Quick Answer
The answer is to scale up the database to a higher service tier, such as S2 or S3. This is correct because the S1 tier provides a fixed number of Database Transaction Units (DTUs), and when a reporting application experiences slow performance, the bottleneck is often insufficient compute or I/O resources. Scaling up increases the DTU allocation, directly improving throughput for report queries without requiring any changes to application code. On the Microsoft Azure Database Administrator Associate DP-300 exam, this scenario tests your understanding of Azure SQL Database service tiers and resource governance—a common trap is to immediately suggest indexing or partitioning, but those address query optimization, not resource starvation. Remember that read scale-out is only available on Premium or Business Critical tiers, so for a Standard tier like S1, scaling up is the only direct path to more DTUs. Memory tip: “S1 is too slow—scale up the DTU flow.”
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 have an Azure SQL Database that is used by a reporting application. Reports run slowly during the day. You notice that the database is at the S1 tier. You need to improve report performance without changing application code. What should you do?
Rebuild fragmented indexes.
Why wrong: Index maintenance can help but may not resolve resource shortage.
Scale up the database to a higher service tier.
Higher DTU allocation directly improves throughput.
Implement table partitioning.
Why wrong: Partitioning may improve manageability, not necessarily performance.
Enable read scale-out to offload reports.
Why wrong: Read scale-out is not available at standard tier.
Answer choices
Answer the question above first, then reveal the full breakdown to understand why each option is right or wrong.
Correct answer & explanation
Scale up the database to a higher service tier.
Option B is correct because scaling up to a higher service tier (e.g., S2 or S3) provides more DTUs, improving report performance. Option A is wrong because index maintenance helps but may not be sufficient if resource is the bottleneck. Option C is wrong because read scale-out is only available on Premium/Business Critical. Option D is wrong because partitioning adds complexity and is not a guaranteed fix.
Key principle: Answer the scenario, not the keyword: identify the specific constraint before choosing the most familiar-sounding option.
Answer analysis
For each option: why learners choose it and why it is or isn't the right answer here.

Common exam traps
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
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.
Key takeaway
Answer the scenario, not the keyword: identify the specific constraint before choosing the most familiar-sounding option.
Real-world example
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.
