Quick Answer
The answer is the Premium or Business Critical service tier combined with an auto-failover group. These two actions are required because the Premium or Business Critical tier uses locally redundant storage with synchronous replication, ensuring that every transaction is committed on both the primary and secondary replicas before acknowledgment, which eliminates data loss during a failover. The auto-failover group then orchestrates the automatic, coordinated switch to a secondary region, maintaining the zero-data-loss guarantee. On the DP-300 exam, this tests your understanding of how service tier replication modes directly impact recovery point objectives; a common trap is assuming the General Purpose tier’s asynchronous replication can achieve zero data loss, but it cannot. Remember the mnemonic “Sync for Zero” — synchronous replication in Premium or Business Critical is the only path to zero data loss, while auto-failover groups provide the automatic orchestration.
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.
Which TWO actions are required to implement Azure SQL Database automatic failover with zero data loss?
Create an auto-failover group.
Auto-failover groups manage failover orchestration.
Configure active geo-replication.
Why wrong: Geo-replication is asynchronous.
Enable read scale-out.
Why wrong: Read scale-out does not affect failover.
Use Premium or Business Critical service tier.
These tiers support synchronous replication.
Configure multiple readable secondaries.
Why wrong: Auto-failover groups support one secondary.
Answer choices
Answer the question above first, then reveal the full breakdown to understand why each option is right or wrong.
Correct answer & explanation
Create an auto-failover group.
An auto-failover group is required because it provides automatic failover capability across Azure SQL Database instances, which is essential for achieving zero data loss during a regional outage. The Premium or Business Critical service tier is required because these tiers use locally redundant storage with synchronous replication to ensure that transactions are committed without data loss, unlike the Standard or General Purpose tiers that use asynchronous replication.
Key principle: Answer the scenario, not the keyword: identify the specific constraint before choosing the most familiar-sounding option.

Common exam traps
The trap here is that candidates often confuse active geo-replication (which is asynchronous and can lose data) with auto-failover groups (which can achieve zero data loss only when used with Premium or Business Critical tiers), leading them to select active geo-replication as a correct answer.
Detailed technical explanation
Azure SQL Database auto-failover groups rely on the Premium or Business Tier's synchronous replication within a region to ensure all committed transactions are replicated to the secondary before acknowledging the commit. During a failover, the secondary becomes the primary with no data loss because the replication is synchronous, and the auto-failover group handles DNS updates and connection string redirection automatically. In a real-world scenario, if a regional outage occurs, the auto-failover group triggers a failover within minutes, but the synchronous replication ensures that no transactions are lost, even if the primary becomes unavailable.
Key takeaway
Answer the scenario, not the keyword: identify the specific constraint before choosing the most familiar-sounding option.
Real-world example
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.
