Basic Concept: This question tests high availability and disaster recovery design for Azure SQL, SQL Server on Azure VMs, and regional failure scenarios.
Why A is Correct: Create a proximity group and an availability set. Deploy each virtual machine to the availability set Add both virtual machines to the proximitygroup. is correct because it is the feature whose normal purpose matches the stated requirement. Create a proximity group and an availability set. Deploy each virtual machine to the availability set Add both virtual machines to the proximitygroup. is part of the availability or recovery design space, but the correct choice must satisfy the specified failover, restore, quorum, RPO, or RTO requirement. The scenario wording points to that specific behavior: You need to recommend a deployment solution that meets the following requirements: • Provides a Service Level Agreement (SLA) of at least 99.95% • Replicates databases in the same group synchronously • Minimizes the latency of database writes What should you r
Why B is Wrong: Create two proximity groups and a single availability set. Deploy both virtual machines to the availability set. Add one virtual machine to each proximity group. 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 is not wrong technology in general, but it is the wrong HA/DR control for this scenario ' s failure model.
Why C is Wrong: Create two proximity groups and two availability sets. Deploy each virtual machine to a unique availability set. Add one virtual machine to each proximity group. 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: Create a proximity group and two availability sets. Deploy each virtual machine to a unique availability set. Add both virtual machines to the proximity group. 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.
