The answer is to enable serverless with auto-pause enabled. This configuration directly addresses the cost optimization need because auto-pause automatically suspends the database when no connections or transactions occur, which for SalesDB means it will pause from 6 PM to 8 AM daily, eliminating compute charges during off-hours. On the Microsoft Azure Database Administrator Associate DP-300 exam, this scenario tests your understanding of serverless compute tier behavior versus provisioned tiers, and a common trap is to overthink scaling options like reducing vCores or changing service tiers—but auto-pause is the most effective lever for intermittent usage patterns. Remember the memory tip: “If it sleeps, it saves”—auto-pause is your go-to for databases that don’t need 24/7 compute, making it a direct and efficient cost optimization strategy for business-hours-only workloads.
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. Read the scenario carefully and evaluate each option against the stated constraints before committing to an answer. 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?
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
}
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 D is correct because enabling auto-pause will pause the database during off-hours, reducing costs. Option A is wrong because reducing vCores might help but auto-pause is more effective. Option B is wrong because changing to Hyperscale may not reduce costs for this pattern. Option C is wrong because storage reduction is not as impactful.
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
Option-by-option breakdown
For each option: why learners choose it and why it is or isn't the right answer here.
✗
Reduce storage to 512 GB.
Why it's wrong here
Storage cost is low; main cost is compute.
✗
Change tier to Hyperscale.
Why it's wrong here
Hyperscale is more expensive for small workloads.
✓
Enable serverless with auto-pause enabled.
Why this is correct
Serverless auto-pause stops compute billing when idle.
Related concept
Static NAT maps one inside address to one outside address.
✗
Reduce capacity to 2 vCores.
Why it's wrong here
Reducing vCores saves some cost but doesn't eliminate idle costs.
Common exam traps
Common exam trap: NAT rules depend on direction and matching traffic
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
How to think about this question
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.
KKey Concepts to Remember
Static NAT maps one inside address to one outside address.
PAT allows many inside hosts to share one public address using ports.
Inside local and inside global describe the private and translated addresses.
NAT ACLs identify traffic for translation, not always security filtering.
TExam Day Tips
→Identify inside and outside interfaces first.
→Check whether the scenario needs static NAT, dynamic NAT or PAT.
→Do not confuse NAT matching ACLs with normal packet-filtering intent.
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
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.

Variation 1. What effect does the command in the exhibit have on the database?
easy
A.Enables auto-pause with a delay of 1 minute.
B.Configures the database to pause after 1 second of inactivity.
✓ C.Disables auto-pause for the database.
D.Sets auto-pause delay to 1 hour.
Why C: Option C is correct because setting AutoPauseDelay to -1 disables auto-pause for serverless databases. Option A is wrong because it's not enabling auto-pause. Option B is wrong because it's not setting a specific delay. Option D is wrong because it's not changing service tier.
