AWS Certified SysOps Administrator – Associate — Question 184

A SysOps administrator is tasked with analyzing database performance. The database runs on a single Amazon RDS DB instance. The SysOps administrator finds that, during times of peak traffic, resources on the database are overutilized due to the amount of read traffic.

Which actions should the SysOps administrator take to improve RDS performance? (Choose two.)

Answer options

• A. Add a read replica
• B. Modify the application to use Amazon ElastiCache for Memcached.
• C. Migrate the database from RDS to Amazon DynamoDB.
• D. Migrate the database to Amazon EC2 with enhanced networking enabled.
• E. Upgrade the database to a Multi-AZ deployment.

Correct answer: A, B

Explanation

Adding a read replica (option A) distributes the read traffic, effectively reducing the load on the primary database instance. Modifying the application to use Amazon ElastiCache for Memcached (option B) also helps by caching frequent queries, thus alleviating read pressure on the database. The other options either involve significant changes that may not directly resolve the read traffic issue or are not optimal for the current scenario.
