AWS Certified Database – Specialty — Question 283

A large financial services company is using AWS Database Migration Service (AWS DMS) to migrate databases from on-premises to the AWS Cloud. During the migration of one of the databases, the AWS DMS replication instance entered a storage-full status. A database administrator needs to troubleshoot and fix the issue.

Which options would help the database administrator resolve this issue? (Choose two.)

Answer options

• A. Change the size of the replication instance to a larger supported instance type.
• B. Use the AWS Management Console to modify the replication task settings to the limited large binary object (LOB) mode and set the value to 16.
• C. Use the AWS CLI to modify the replication task settings with ‘{“Logging”: {“DeleteTaskLogs”: true}}’.
• D. Use the AWS CLI to modify the replication task settings with ‘{“Logging”: {“CloudWatchLogGroup”: null}}’.
• E. Use the modify-replication-instance API to increase the amount of storage allocated to the replication instance.

Correct answer: A, E

Explanation

To resolve a storage-full status on an AWS DMS replication instance, you must increase the physical storage available to the instance. This can be accomplished by using the modify-replication-instance API to allocate more storage, or by changing the replication instance to a larger instance type that supports more storage. Modifying task logs or LOB settings will not immediately free up or scale the instance's storage capacity to resolve the error.
