DP-300 Practice Question: Plan and configure a high availability and disaster recovery environment
A small business uses Azure SQL Database single database in the General Purpose tier for its inventory management system. The database is located in the Brazil South region. The business wants a disaster recovery solution that can automatically fail over to a secondary region in case of an outage, with an RPO of less than 1 hour and an RTO of less than 2 hours. The budget is limited, so the solution must be cost-effective. What should you recommend?
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 secondary database in a different region using the General Purpose tier.
A failover group with a secondary in another region provides automatic failover with low RPO (<1 hour) and RTO (<2 hours), and using the General Purpose tier is cost-effective. Option B is wrong because zone redundancy provides high availability within a single region, not disaster recovery across regions. Option C is wrong because geo-restore from geo-redundant backups has an RTO of several hours (typically 7-12 hours), which exceeds the required 2 hours. Option D is wrong because upgrading to Business Critical tier is more expensive and not necessary for the RPO/RTO requirements; geo-replication is already available in General Purpose through failover groups.
