Correct answer & explanation
✓
Deploy the instance in Business Critical tier with zone-redundant configuration.
For zone redundancy in Azure SQL Managed Instance, the Business Critical tier is required. Option D is correct because it specifies deploying in Business Critical tier with zone-redundant configuration, which provides resilience within a single region across availability zones. Option A is incorrect because a failover group to another region addresses regional disasters, not zonal failures. Option B is incorrect because the General Purpose tier does not support zone redundancy. Option C is incorrect because Hyperscale is a service tier for Azure SQL Database, not for Managed Instance.
