The answer is to use an Azure Automation runbook with PowerShell to check metrics and scale. This is correct because Azure SQL Database does not natively support autoscale for elastic pool DTU; scaling must be implemented programmatically by querying CPU metrics via Azure Monitor and triggering a PowerShell script that adjusts the pool’s DTU settings. On the Microsoft Azure Database Administrator Associate DP-300 exam, this scenario tests your understanding of Azure SQL Database’s limitations and the need for custom automation solutions—a common trap is assuming built-in autoscale exists or confusing SQL Agent jobs (unavailable in Azure SQL Database) with runbook capabilities. Remember, elastic pools require external orchestration: think “no native autoscale, so automate with runbooks.”
DP-300 Configure and manage automation of tasks Practice Question
This DP-300 practice question tests your understanding of configure and manage automation of tasks. 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.
A company uses Azure SQL Database with elastic pools. They need to automatically scale up the pool DTU when CPU usage exceeds 80% for 5 minutes and scale down when below 20% for 10 minutes. Which solution should they implement?
Answer the question above first, then reveal the full breakdown to understand why each option is right or wrong.
Correct answer & explanation
✓
Use Azure Automation runbook with PowerShell to check metrics and scale
Azure SQL Database autoscale is not natively supported; scaling must be done programmatically. Azure Automation with PowerShell runbooks can query metrics and trigger scaling. SQL Agent jobs are not available in Azure SQL Database. Elastic Database Transactions are for distributed transactions, not scaling. Azure Logic Apps can also be used but are more complex for this scenario.
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.
✗
Use Elastic Database Transactions to handle scaling
Why it's wrong here
Elastic Database Transactions are for distributed transactions, not scaling.
✗
Configure autoscale settings on the elastic pool in the Azure portal
Why it's wrong here
Azure SQL Database elastic pools do not have built-in autoscale.
✓
Use Azure Automation runbook with PowerShell to check metrics and scale
Why this is correct
Azure Automation runbooks can use Get-AzMetric and Set-AzSqlElasticPool to implement custom autoscaling.
Related concept
Static NAT maps one inside address to one outside address.
✗
Create a SQL Agent job to monitor and alter the pool
Why it's wrong here
SQL Agent is not available in Azure SQL Database.
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
An e-commerce site experiences heavy traffic on Black Friday and near-zero traffic during off-peak weeks. Rather than provisioning permanent large VMs, the team uses auto-scaling groups that add capacity automatically under load and reduce it overnight. Questions like this test whether you understand elasticity, availability zones, and cloud compute scaling patterns.
