You have an on-premises Microsoft SQL Server 2022 instance that hosts a database named DB1. You have an Azure subscription that contains an Azure SQL database named SQLDB1. You need to replicate DB1 to SQLDB1. Which type of replication should you use?
Correct Answer: B
Basic Concept: This question tests plan and configure a high availability and disaster recovery (ha/dr) environment in the DP-300 exam context. The correct choice is determined by the exact service boundary and operational requirement stated in the scenario.
Why B is Correct: peer-to-peer is part of the availability or recovery design space, but the correct choice must satisfy the specified failover, restore, quorum, RPO, or RTO requirement. In this scenario, the important constraint is: You need to replicate DB1 to SQLDB1. peer-to-peer satisfies that constraint without adding an unrelated service or manual process.
Why A is Wrong: snapshot is part of the availability or recovery design space, but the correct choice must satisfy the specified failover, restore, quorum, RPO, or RTO requirement. It handles a different resilience pattern and would not deliver the failover or recovery behavior required here.
Why C is Wrong: merge is part of the availability or recovery design space, but the correct choice must satisfy the specified failover, restore, quorum, RPO, or RTO requirement. It does not meet the failover, restore, quorum, or cross-region continuity target stated in the question, even if it is valid in a different availability design.
Why D is Wrong: transactional is part of the availability or recovery design space, but the correct choice must satisfy the specified failover, restore, quorum, RPO, or RTO requirement. It handles a different resilience pattern and would not deliver the failover or recovery behavior required here.
