Topic 1 Question 259
2 つ選択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?
Add a read replica
Modify the application to use Amazon ElastiCache for Memcached.
Migrate the database from RDS to Amazon DynamoDB.
Migrate the database to Amazon EC2 with enhanced networking enabled.
Upgrade the database to a Multi-AZ deployment.

- 正解だと思う選択肢: AB
A & B - Migrating to DynamoDB or to an EC2 are clearly irrelevant. Creating a Multi-AZ RDS instance will not improve performance either. A read replica and/or a caching layer in front of the DB will reduce the traffic on the server.

A. Adding a read replica can offload read traffic from the primary RDS instance to the replica, thus improving performance during times of peak traffic.
B. Amazon ElastiCache for Memcached is an in-memory data store that can be used to improve read performance.
