DEA-C01 Data Store Management Practice Question

Network Topology
aws rds describe-db-instancesdb-instance-identifier mydbquery 'DBInstances[0].[Engineoutput textRefer to the exhibit.Output:mysql available False None

Refer to the exhibit. A data engineer ran the CLI command to check the configuration of an RDS instance named 'mydb'. Which statement accurately describes the current configuration?

⚠ Common exam trap

AWS often tests the misconception that a database with 'available' status must be a read replica or Multi-AZ, but the absence of the 'ReadReplicaSourceDBInstanceIdentifier' and 'MultiAZ: False' clearly identify it as a standalone Single-AZ instance.

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 a Single-AZ deployment and is not a read replica

The CLI command output shows 'DBInstanceStatus: available' and 'MultiAZ: False', indicating the database is running as a Single-AZ deployment. Additionally, the absence of a 'SourceDBInstanceIdentifier' field confirms it is not a read replica. The 'ReadReplicaSourceDBInstanceIdentifier' is not present, which would be required if it were a read replica.
