DP-300 Practice Question: Plan and configure a high availability and disaster recovery environment
Network Topology
Refer to the exhibit. You run the Azure CLI command to check the configuration of an Azure SQL Database named db1. The output shows zoneRedundant is true and replicationRole is Primary. Which statement is true about this database?
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
✓
The database is zone-redundant and is the primary database in its replication relationship.
The output shows zoneRedundant is true and replicationRole is Primary. Zone redundancy means the database has replicas in different availability zones within the same region, and replicationRole being Primary indicates this database is the primary in its replication relationship. Therefore, option B is correct. Option A is incorrect because active geo-replication involves a secondary in a different region, not just zone redundancy. Option C is incorrect because Hyperscale databases have a different architecture; zoneRedundant may be supported but the output does not specify Hyperscale. Option D is incorrect because a readable secondary replica is not indicated; zone redundancy does not necessarily imply a readable secondary.
Answer analysis
Option-by-option breakdown
For each option: why learners choose it and why it is or isn't the right answer here.
- ✗
The database is configured with active geo-replication to a secondary region.
Why it's wrong here
The replicationRole is Primary, not Secondary, so no geo-replication is active.
- ✓
The database is zone-redundant and is the primary database in its replication relationship.
Why this is correct
ZoneRedundant true and replicationRole Primary indicate a zone-redundant primary.
- ✗
The database is a Hyperscale database with zone redundancy enabled.
Why it's wrong here
Hyperscale databases have a different property for zone redundancy.
- ✗
The database has a readable secondary replica in a different Azure availability zone.
Why it's wrong here
Zone redundancy implies replicas in different zones, but the output does not confirm readability.
