The answer is to use active geo-replication and plan a manual failover. This configuration meets the strict RPO of less than 5 seconds because active geo-replication continuously streams transaction log data to a readable secondary database in a different Azure region, keeping it nearly synchronized with the primary. The manual failover process, when initiated promptly, can achieve an RTO of less than 1 hour by quickly redirecting connections to the secondary. On the DP-300 exam, this scenario tests your understanding of how active geo-replication differs from failover groups, which add automatic failover but can introduce slightly higher RTO due to DNS propagation. A common trap is assuming auto-failover groups always provide faster RTO, but manual failover actually gives you tighter control for sub-hour recovery. Memory tip: think “Active sync, manual switch” — the replication is automatic, but the failover action is your call to hit that strict RTO window.
DP-300 Plan and implement data platform resources Practice Question
This DP-300 practice question tests your understanding of plan and implement data platform resources. 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.
You are designing a disaster recovery strategy for an Azure SQL Database that requires a Recovery Point Objective (RPO) of less than 5 seconds and a Recovery Time Objective (RTO) of less than 1 hour. Which option should you choose?
Use auto-failover groups with read-write failover policy.
Why wrong: Auto-failover groups provide RPO less than 5 seconds but RTO may be up to 1 hour with automatic failover; however, the RTO requirement is less than 1 hour, but manual failover with active geo-replication is more predictable.
B
Use geo-restore from geo-redundant backups.
Why wrong: Geo-restore has RPO of 1 hour and RTO of several hours, not meeting requirements.
C
Use active geo-replication and plan manual failover.
Active geo-replication provides RPO less than 5 seconds and manual failover can achieve RTO of less than 1 hour.
D
Use long-term retention (LTR) backups with daily frequency.
Why wrong: LTR backups have RPO of 1 day, not meeting the requirement.
Answer the question above first, then reveal the full breakdown to understand why each option is right or wrong.
Correct answer & explanation
✓
Use active geo-replication and plan manual failover.
Active geo-replication provides a continuous replication stream with an RPO of less than 5 seconds and supports manual failover, which can achieve an RTO of less than 1 hour when the failover is initiated promptly. This option meets the strict RPO and RTO requirements by maintaining a readable secondary in a different Azure region that is kept nearly synchronized with the primary.
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
The trap here is that candidates confuse auto-failover groups (Option A) with active geo-replication, assuming automatic failover always provides a better RTO, but the question's strict RPO of less than 5 seconds and the need for manual control make active geo-replication the correct choice, as auto-failover groups introduce additional latency and automatic detection delays that can push RTO beyond 1 hour.
Detailed technical explanation
How to think about this question
Active geo-replication uses asynchronous replication based on the database transaction log, with a typical replication lag of under 5 seconds under normal conditions. During a manual failover, the secondary database is promoted to primary in seconds, and the application must update its connection string to point to the new primary; the RTO is dominated by this reconnection time and any application-level retry logic, not by data movement. In a real-world scenario, if the primary region experiences a catastrophic failure, the manual failover can be executed within minutes, keeping the RTO well under 1 hour.

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.
