The answer is to configure an Auto-Failover Group with a secondary instance in West US. This is correct because Auto-Failover Groups for Azure SQL Managed Instance use synchronous replication at the commit level when the secondary is set as readable, achieving a replication lag target of less than 5 seconds and thus meeting the strict RPO requirement. On the Microsoft Azure Database Administrator Associate DP-300 exam, this scenario tests your understanding of high-availability and disaster recovery options, specifically the difference between failover groups and geo-replication; a common trap is choosing geo-replication, which offers asynchronous replication with higher potential data loss. Remember the key distinction: for automatic failover and sub-5-second data loss on a managed instance, you must pair an Auto-Failover Group with a readable secondary. A useful memory tip is “Failover Group for automatic, readable secondary for low RPO.”
DP-300 Practice Question: Plan and configure high availability and disaster recovery
This DP-300 practice question tests your understanding of plan and configure high availability and disaster recovery. 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 has an Azure SQL Managed Instance in the East US region. They need to implement disaster recovery with automatic failover to a paired region. The solution must minimize data loss to less than 5 seconds. Which feature should they use?
Clue words in this question
Noticing these words before you look at the options changes how you read each choice.
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.
Answer the question above first, then reveal the full breakdown to understand why each option is right or wrong.
Correct answer & explanation
✓
Configure an Auto-Failover Group with a secondary instance in West US
Option C is correct because Auto-Failover Groups for Azure SQL Managed Instance provide automatic failover to a paired region (West US) with a replication lag target of less than 5 seconds when using the Readable Secondary option. This feature uses synchronous replication at the commit level to minimize data loss, meeting the RPO requirement of <5 seconds.
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.
✗
Active Geo-Replication with a secondary in East US 2
Why it's wrong here
Active Geo-Replication is not supported for SQL Managed Instance.
✗
Enable geo-redundant backup storage and restore to West US
Why it's wrong here
Geo-restore has RPO of hours, not seconds.
✓
Configure an Auto-Failover Group with a secondary instance in West US
Why this is correct
Auto-failover groups for managed instance provide automatic failover and RPO of 5 seconds.
Clue confirmation
The clue word "minimum / minimize" in the question point toward this answer.

✗
Set up a Failover Group with manual failover to a secondary in West US
Why it's wrong here
Manual failover is not automatic.
Common exam traps
Common exam trap: answer the scenario, not the keyword
The trap here is confusing Active Geo-Replication (which is for Azure SQL Database, not Managed Instance) with Auto-Failover Groups, leading candidates to select Option A even though it is unsupported for Managed Instance.
Detailed technical explanation
How to think about this question
Auto-Failover Groups for SQL Managed Instance use a distributed availability group under the hood, leveraging Always On Availability Groups technology with synchronous commit between the primary and secondary instances. The replication lag is typically under 1 second in most configurations, but the SLA guarantees an RPO of 5 seconds. In a real-world scenario, network latency between paired regions (e.g., East US to West US) can occasionally cause brief replication delays, but the automatic failover policy ensures that data loss remains within the defined threshold.

TExam Day Tips
→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.
