The answer is to configure per-database min eDTU for the critical database. This setting guarantees a baseline level of resources by reserving a specific amount of eDTU for that database, even when the elastic pool is under high contention, ensuring it never starves for compute or IO. In contrast, per-database max eDTU only caps usage, and simply increasing the pool’s total DTU does not guarantee any single database gets those resources. On the DP-300 exam, this scenario tests your understanding of resource governance within elastic pools, where the common trap is confusing min (guarantee) with max (limit). A memory tip: think of “min” as a floor that holds up your critical database, while “max” is a ceiling that holds it back.
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 part of an elastic pool. You notice that the pool's eDTU consumption is consistently high, and some databases are experiencing resource contention. You need to ensure that a critical database always gets a minimum amount of resources. What should you configure?
Clue words in this question
Noticing these words before you look at the options changes how you read each choice.
Clue: "always"
Why it matters: Absolute qualifier. An answer using 'always' is only correct if there are genuinely no exceptions — absolute statements are often wrong in networking.
Clue: "minimum / minimize"
Why it matters: Asks for the least resource use — fewest addresses, smallest subnet, lowest overhead. Eliminate over-provisioned options even if they would technically work.
Answer the question above first, then reveal the full breakdown to understand why each option is right or wrong.
Correct answer & explanation
✓
Configure per-database min eDTU for the critical database
Option B is correct because per-database min eDTU guarantees resources for a database. Option A is wrong because per-database max eDTU limits resource usage, not guarantee. Option C is wrong because DTU increase for the pool may not guarantee resources for a specific database. Option D is wrong because moving to a different pool may not be efficient.
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.
✗
Configure per-database max eDTU for the critical database
Why it's wrong here
Max eDTU limits, does not guarantee resources.
✗
Increase the eDTU of the elastic pool
Why it's wrong here
Increases overall resources but does not guarantee for a specific database.
✗
Move the critical database to a dedicated service tier
Why it's wrong here
This may solve contention but is more costly than using min eDTU.
✓
Configure per-database min eDTU for the critical database
Why this is correct
Min eDTU guarantees a minimum amount of resources.

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.

Variation 1. Your organization uses Azure SQL Database with elastic pools. One of the databases in the pool, 'OrdersDB', consistently uses more eDTUs than other databases, causing performance degradation for other databases. You need to isolate the resource usage of 'OrdersDB' to prevent it from affecting others. The solution should minimize cost and administrative overhead. What should you do?
hard
A.Purchase reserved capacity for the pool to reduce costs.
B.Use Query Store to identify and kill the high-usage queries.
✓ C.Move 'OrdersDB' to a higher service tier, such as a standalone database with a higher DTU limit.
D.Increase the eDTU limit of the elastic pool to accommodate the high usage.
Why C: Option D is correct because moving the database to a higher service tier or a separate pool isolates its resource usage and prevents impact on others. Option A is wrong because scaling the pool affects all databases. Option B is wrong because query store does not limit resources. Option C is wrong because reserved capacity is a billing benefit, not a resource isolation mechanism.
