How to Resolve Manually
This rule checks whether replication is enabled for Amazon Aurora and Hermes clusters. If a cluster is found with only one cluster instance deployed, it will be marked as non-compliant.
To resolve this, go to Amazon RDS console and then to Databases from the left-side menu.
Look for the non-compliant cluster and select it from the radio button. Click on the Actions menu and then click on Add reader.
From there you can add a replica to another AZ in order to make the rule compliant. Check the following screenshot as reference:
