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?
⚠ Common exam trap
DP-300 often tests the confusion between zone redundancy (intra-region HA) and geo-replication (cross-region DR), so candidates incorrectly assume zoneRedundant=true implies a secondary region or readable replica.
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, meaning the database is deployed across multiple availability zones within its region for high availability, and replicationRole is Primary, meaning it is the primary in a replication relationship (such as a failover group or active geo-replication). Option B correctly combines both facts. The zoneRedundant flag has nothing to do with cross-region replication, so options A and D are incorrect, and Hyperscale is a separate service tier not indicated by these properties.
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
Active geo-replication creates a readable secondary in a separate region, which the output does not show; zoneRedundant concerns zones within one region. Geo-replication would be correct if replicationRole were Secondary or a partner server were listed.
- ✓
The database is zone-redundant and is the primary database in its replication relationship.
Why this is correct
The CLI output directly reports zoneRedundant true, meaning replicas span availability zones, and replicationRole Primary, meaning this database accepts writes in its geo-replication relationship. Both properties are read straight from the returned configuration, so the statement matches the observed values.
- ✗
The database is a Hyperscale database with zone redundancy enabled.
Why it's wrong here
The output shows zoneRedundant and replicationRole only; neither property identifies the service tier. Hyperscale databases can be zone redundant, but so can Business Critical, so the exhibit cannot confirm Hyperscale. Hyperscale would be the answer only if the tier were explicitly shown.
- ✗
The database has a readable secondary replica in a different Azure availability zone.
Why it's wrong here
Zone redundancy places replicas across availability zones within one region; it does not create a readable secondary. A readable secondary requires active geo-replication or an auto-failover group, which the zoneRedundant and replicationRole Primary output does not evidence.
