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. The scenario asks you to isolate a root cause — eliminate options that address a different problem before choosing. 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.
Exhibit
Refer to the exhibit. The following Azure CLI output shows the configuration of an Azure SQL Database:
{
"name": "SalesDB",
"tier": "GeneralPurpose",
"capacity": 4,
"family": "Gen5",
"storage": 1024,
"auto_pause_delay": 60
}
You need to optimize costs for SalesDB, which is used only during business hours (8 AM to 6 PM). The database currently runs 24/7. Which two changes should you make?
Exhibit

{

"tier": "GeneralPurpose",
"capacity": 4,
"family": "Gen5",
"storage": 1024,
"auto_pause_delay": 60
}
A
Reduce storage to 512 GB.
Why wrong: Storage cost is low; main cost is compute.
B
Change tier to Hyperscale.
Why wrong: Hyperscale is more expensive for small workloads.
C
Enable serverless with auto-pause enabled.
Serverless auto-pause stops compute billing when idle.
D
Reduce capacity to 2 vCores.
Why wrong: Reducing vCores saves some cost but doesn't eliminate idle costs.
Answer the question above first, then reveal the full breakdown to understand why each option is right or wrong.
Correct answer & explanation
✓
Enable serverless with auto-pause enabled.
Option C is correct because enabling serverless with auto-pause allows SalesDB to automatically pause during off-hours (6 PM to 8 AM) when not in use, significantly reducing compute costs for a database used only during business hours. Option D is incorrect because reducing vCores alone does not stop charges during idle time, while auto-pause eliminates compute costs entirely when paused. Option A is incorrect because storage reduction does not address the core issue of paying for idle compute. Option B is incorrect because Hyperscale is designed for high-performance, large-scale workloads and is not cost-optimized for a schedule-based usage pattern.
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 startup's cloud architect reviews their monthly bill and notices costs are higher than expected for a long-running batch job. Switching from on-demand instances to Reserved Instances — or using Spot/Preemptible VMs — can reduce compute costs by up to 72 %. Questions like this test whether you understand the tradeoffs between commitment, flexibility, and cost across cloud pricing models.
