The correct answer is to configure an Azure Monitor metric alert on a heartbeat or custom metric that detects primary unavailability for over 5 minutes, linked to an action group that triggers an Azure Automation runbook executing the failover PowerShell cmdlet. This solution automates failover for Azure SQL Database geo-replication by using Azure Monitor’s alerting to confirm sustained unreachability, then invoking a runbook to perform the planned or forced failover without manual steps, while the action group simultaneously sends an alert to the operations team. On the DP-300 exam, this scenario tests your understanding of integrating Azure Monitor alerts with Automation runbooks for disaster recovery workflows, often trapping candidates who select Azure Site Recovery (which is for VMs, not SQL DB geo-replication) or manual failover options. Remember: for automated geo-replication failover, pair a metric alert with a runbook—think “Alert + Runbook = Auto-Failover.”
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. 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 manage an Azure SQL Database that supports a critical financial application. The database is in the General Purpose tier and uses active geo-replication for disaster recovery. You need to automate the process of failing over to the secondary region in case of a regional outage, but only after confirming that the primary is unreachable for more than 5 minutes. Additionally, you need to send an alert to the operations team when the failover occurs. The solution should use Azure services and minimize manual steps. What should you implement?
Clue words in this question
Noticing these words before you look at the options changes how you read each choice.
Clue: "primary"
Why it matters: Asks for the main purpose or function, not a secondary benefit. Eliminate answers that describe side-effects or partial functions.
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.
Use Azure Logic Apps with a timer trigger to check the database status every minute and initiate failover if unreachable.
Why wrong: Less reliable and may incur higher costs.
B
Schedule a SQL Agent job on the secondary to run a script that checks connectivity and fails over.
Why wrong: SQL Agent not available in Azure SQL Database.
C
Configure Azure Site Recovery for the SQL database.
Why wrong: Site Recovery is for VMs, not Azure SQL Database.
D
Configure an Azure Monitor metric alert on the 'Deadlock count' metric (or custom metric) with a threshold of 0 for 5 minutes, then use an action group to trigger an Azure Automation runbook that runs the failover PowerShell cmdlet.
Monitor can detect unavailability and trigger automated failover via runbook.
Answer the question above first, then reveal the full breakdown to understand why each option is right or wrong.
Correct answer & explanation
✓
Configure an Azure Monitor metric alert on the 'Deadlock count' metric (or custom metric) with a threshold of 0 for 5 minutes, then use an action group to trigger an Azure Automation runbook that runs the failover PowerShell cmdlet.
Option A is correct because Azure Monitor can detect the primary database unavailability (e.g., through heartbeat metrics) and trigger an alert that invokes an Azure Automation runbook to perform the failover. Options B and C require manual intervention. Option D (Azure Site Recovery) is not designed for SQL Database geo-replication failover.
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 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.
