AWS Certified Database – Specialty — Question 100

A company is migrating its on-premises database workloads to the AWS Cloud. A database specialist performing the move has chosen AWS DMS to migrate an
Oracle database with a large table to Amazon RDS. The database specialist notices that AWS DMS is taking significant time to migrate the data.
Which actions would improve the data migration speed? (Choose three.)

Answer options

• A. Create multiple AWS DMS tasks to migrate the large table.
• B. Configure the AWS DMS replication instance with Multi-AZ.
• C. Increase the capacity of the AWS DMS replication server.
• D. Establish an AWS Direct Connect connection between the on-premises data center and AWS.
• E. Enable an Amazon RDS Multi-AZ configuration.
• F. Enable full large binary object (LOB) mode to migrate all LOB data for all large tables.

Correct answer: A, C, D

Explanation

Creating multiple AWS DMS tasks can parallelize the migration process, thus improving speed. Increasing the capacity of the AWS DMS replication server allows it to handle more data efficiently. Establishing an AWS Direct Connect connection can provide a faster and more reliable network connection, optimizing data transfer rates. The other options do not directly enhance migration speed as they either focus on redundancy or settings that do not affect performance significantly.
