DP-300 Practice Question: Plan and configure a high availability and disaster recovery environment
Your company uses Azure SQL Database with active geo-replication for disaster recovery. During a drill, you need to verify that the secondary database is ready for failover and that data synchronization is current. Which query should you run on the secondary database?
Answer choices
Why each option matters
Answer the question above first, then reveal the full breakdown to understand why each option is right or wrong.
Correct answer & explanation
✓
SELECT * FROM sys.dm_geo_replication_link_status;
Sys.dm_geo_replication_link_status provides replication lag and the last replicated transaction for geo-replicated databases. Option A is wrong because sys.dm_continuous_copy_status is deprecated and no longer used for geo-replication monitoring. Option C is wrong because sys.dm_database_copies is for copy-only operations, not ongoing replication. Option D is wrong because sys.dm_replication_status is for transactional replication, not geo-replication.

Same concept, more angles
1 more way this is tested on DP-300
These questions test the same concept from different angles. Work through them to make sure you can recognise it however the exam phrases it.
Variation 1. You have an Azure SQL Database with active geo-replication. You need to monitor the replication lag to ensure the RPO is met. Which metric should you monitor?
medium- A.DTU consumption
- ✓ B.Replication lag
- C.Data IO percentage
- D.Deadlocks
Why B: 'Replication lag' metric directly measures the delay in seconds between primary and secondary. Option A (Data IO percentage) is a performance metric. Option C (DTU consumption) is related to resource usage. Option D (Deadlocks) is unrelated.
