DP-300 Practice Question: Plan and configure a high availability and disaster recovery environment
You are a database administrator for a healthcare company that uses Azure SQL Database for its electronic health records (EHR) system. The database is in the West Europe region using the General Purpose service tier. The company is expanding to the United States and wants to set up disaster recovery with the secondary in East US. The requirements are: RPO of 5 minutes and RTO of 1 hour. The application should automatically failover without manual intervention. Additionally, you must ensure that the secondary database is not used for read traffic to avoid any performance impact on the primary. What should you configure?
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
✓
Create a failover group with a non-readable secondary in East US and enable auto-failover.
A failover group with auto-failover and a non-readable secondary meets all requirements: RPO of 5 minutes can be achieved with async replication, RTO of 1 hour with automatic failover, and no read traffic. Option A is wrong because active geo-replication alone does not provide automatic failover. Option B is wrong because a readable secondary would be used for read traffic. Option D is wrong because zone-redundancy doesn't protect regionally.
Answer analysis
Option-by-option breakdown
For each option: why learners choose it and why it is or isn't the right answer here.
- ✗
Configure active geo-replication to a secondary database in East US and set up a custom monitoring script to trigger failover.
Why it's wrong here
Active geo-replication does not have automatic failover; custom scripting adds complexity and may not meet RTO.
- ✗
Create a failover group with a readable secondary in East US and enable auto-failover.
Why it's wrong here
A readable secondary could be used for read traffic, which is not desired.
- ✓
Create a failover group with a non-readable secondary in East US and enable auto-failover.
Why this is correct
Auto-failover group meets the RPO/RTO, and non-readable secondary prevents read traffic.
- ✗
Deploy a zone-redundant General Purpose database in West Europe and use geo-restore to East US.
Why it's wrong here
Zone-redundancy does not protect regionally, and geo-restore cannot meet the RTO.
