AWS Certified CloudOps Engineer Associate SOA-C03 Practice Question

An ecommerce company runs a MySQL 8.0 DB instance in one AZ. During flash sales, Amazon CloudWatch shows the DatabaseConnections metric spikes close to the instance limit and FreeableMemory falls sharply. Hundreds of short-lived Lambda invocations open new database sessions. The team wants to relieve memory pressure without changing application logic and would like to use IAM database authentication. Which solution meets these requirements with the least effort?

  • Add a read replica and configure the Lambda functions to spread writes and reads using Amazon Route 53 weighted records.

  • Deploy an Amazon ElastiCache for Memcached cluster and cache connection objects for reuse across function invocations.

  • Launch a larger DB instance class and increase the max_connections parameter in a custom parameter group.

  • Create an Amazon RDS Proxy for the DB instance, enable IAM authentication, and update the Lambda functions to connect to the proxy endpoint.
