The correct answer is to create a failover group with an automatic failover policy and add the databases. This configuration is essential because a failover group provides a single listener endpoint that remains unchanged after a forced failover, and the automatic failover policy ensures that during a regional outage, the secondary Azure SQL Managed Instance becomes the primary without any manual intervention. On the Microsoft Azure Database Administrator Associate DP-300 exam, this scenario tests your understanding of how failover groups differ from active geo-replication, which lacks a unified listener and requires manual failover. A common trap is confusing automatic failover with a separate setting or thinking Azure Traffic Manager is needed, but the failover group listener itself handles endpoint continuity. Remember the memory tip: "Auto group, single listener, no manual needed" — if you see a question about automatic regional failover with a stable endpoint, think failover group with automatic policy.
DP-300 Practice Question: Plan and configure a high availability and disaster recovery environment
This DP-300 practice question tests your understanding of plan and configure a high availability and disaster recovery environment. 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 are configuring a failover group for a pair of Azure SQL Managed Instances in different regions for disaster recovery. The primary instance experiences a regional outage. You need to ensure that after a forced failover, the secondary instance automatically becomes the primary without any manual intervention and that applications can connect using the same listener endpoint. What should you configure?

Correct answer & explanation
✓
Create a failover group with automatic failover policy and add the databases.
Option C is correct because a failover group with automatic failover policy ensures that during a regional outage, the secondary database becomes the primary automatically and the listener endpoint remains unchanged. Option A is wrong because active geo-replication does not provide a single listener endpoint and requires manual failover. Option B is wrong because auto-failover groups are the correct feature, not a separate setting. Option D is wrong because Azure Traffic Manager is not needed; the failover group listener provides the endpoint.
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.
✗
Use Azure Traffic Manager with priority routing to the secondary instance.
Why it's wrong here
Traffic Manager is not required; the failover group listener handles the endpoint.
✗
Enable auto-failover groups on the primary instance.
Why it's wrong here
Auto-failover groups are the correct mechanism, but the answer is incomplete without specifying the failover policy.
✗
Configure active geo-replication between the instances.
Why it's wrong here
Active geo-replication requires manual failover and does not provide a single listener endpoint.
✓
Create a failover group with automatic failover policy and add the databases.
Why this is correct
A failover group with automatic failover provides a listener endpoint and automatic failover during an outage.

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 cloud solutions architect for a retail company is evaluating services for a new workload. The correct answer here reflects best practice for the specific scenario described — not a general cloud recommendation. Answer the scenario, not the keyword: identify the specific constraint before choosing the most familiar-sounding option. Cloud exam questions reward reading the constraint carefully: the same technology can be right or wrong depending on the use case.
