DP-300 Practice Question: Plan and configure a high availability and disaster recovery environment
You manage an Azure SQL Database that uses active geo-replication with a secondary in a paired region. During a planned maintenance, you need to fail over to the secondary with zero data loss. What should you do?
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
✓
Execute a planned failover (graceful failover) using Transact-SQL or PowerShell
A planned failover (graceful failover) synchronizes all transactions between the primary and secondary before switching, ensuring zero data loss. Option A uses a standard failover that may allow data loss if the secondary is not fully synchronized. Option B causes data loss by taking the primary offline abruptly. Option D explicitly allows data loss, which is not acceptable for this requirement.
Answer analysis
Option-by-option breakdown
For each option: why learners choose it and why it is or isn't the right answer here.
- ✗
Use Azure portal to 'Failover' without specifying data loss tolerance
Why it's wrong here
The portal option defaults to forced failover with data loss.
- ✗
Take the primary offline, then promote the secondary
Why it's wrong here
Taking the primary offline without synchronization can cause data loss.
- ✓
Execute a planned failover (graceful failover) using Transact-SQL or PowerShell
Why this is correct
Planned failover synchronizes the secondary before promoting it, ensuring zero data loss.
- ✗
Execute a forced failover allowing data loss
Why it's wrong here
Forced failover may cause data loss if transactions are not replicated.
