DP-300 Practice Question: Plan and configure a high availability and disaster recovery environment
You are designing a disaster recovery plan for an Azure SQL Managed Instance in the East US region. The plan must meet an RPO of 15 minutes and an RTO of 1 hour. You need to minimize costs while meeting these requirements. Which solution 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
✓
Configure a failover group between two General Purpose instances in different regions.
A failover group between two General Purpose instances in different regions provides geo-replication with an RPO of seconds to minutes and an RTO of about 1 hour, meeting the requirements at minimal cost. Option A is incorrect because zone-redundant redundancy only protects against zonal failures within the same region, not regional disasters. Option B is incorrect because deploying a second instance with zone redundancy in the same region does not provide cross-region DR. Option D is incorrect because using Business Critical instances is more expensive and not required for the specified RPO/RTO.
