Quick Answer
The answer is to configure minimum and maximum eDTU per database in the elastic pool. This approach directly addresses the need to optimize elastic pool cost with different usage patterns by guaranteeing each database a baseline resource floor (min eDTU) while capping its burst potential (max eDTU), preventing any single workload from starving others during peak times. On the DP-300 exam, this scenario tests your understanding of elastic pool resource governance, often appearing as a trap where candidates mistakenly choose to scale the entire pool or move to standalone databases, which would increase costs rather than optimize them. The key insight is that min/max eDTU settings allow you to share the pool’s 200 eDTU efficiently across departments with non-overlapping peaks—marketing’s daytime CPU and sales’ nighttime IO—without over-provisioning. Memory tip: think “min for guarantee, max for cap” to avoid the common mistake of adding more databases or switching to vCore, which doesn’t inherently solve cost optimization for varied usage patterns.
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.
You are responsible for a set of Azure SQL Databases that are used by different departments in your organization. The databases are deployed in an elastic pool with Standard tier (eDTU 200). Usage patterns show that the marketing database uses high CPU during the day, while the sales database uses high IO at night. You want to optimize costs while ensuring each database gets the resources it needs. What should you do?
Configure minimum and maximum eDTU per database in the pool
Guarantees resources per database while sharing.
Migrate the pool to a vCore-based elastic pool
Why wrong: Does not address resource allocation per database.
Add more databases to the pool to spread the load
Why wrong: Increases contention.
Move each database to a standalone DTU tier
Why wrong: Increases cost; no sharing.
Answer choices
Answer the question above first, then reveal the full breakdown to understand why each option is right or wrong.
Correct answer & explanation
Configure minimum and maximum eDTU per database in the pool
Option B is correct because configuring minimum and maximum eDTU per database ensures that each database gets guaranteed resources when needed, while still sharing the pool. Option A is wrong because moving to separate standalone databases would increase cost. Option C is wrong because using a vCore pool instead of DTU does not solve the issue inherently. Option D is wrong because adding more databases to the pool increases contention.
Key principle: NAT direction and interface roles matter as much as the IP address mapping. Inside/outside designation controls which traffic is translated.
Answer analysis
For each option: why learners choose it and why it is or isn't the right answer here.
Configure minimum and maximum eDTU per database in the pool
Why this is correct
Guarantees resources per database while sharing.
Related concept
Static NAT maps one inside address to one outside address.
Migrate the pool to a vCore-based elastic pool
Why it's wrong here
Does not address resource allocation per database.
Add more databases to the pool to spread the load
Why it's wrong here
Increases contention.
Move each database to a standalone DTU tier
Why it's wrong here
Increases cost; no sharing.
Common exam traps
NAT is not only about the public address. The inside/outside interface roles and the ACL or rule that matches traffic are just as important.
Detailed technical explanation
NAT questions usually test address translation, overload/PAT behaviour, static mappings and whether the right traffic is being translated. Read the interface direction and address terms carefully.
Key takeaway
NAT direction and interface roles matter as much as the IP address mapping. Inside/outside designation controls which traffic is translated.
Real-world example
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.
