AWS Certified Solutions Architect - Associate SAA-C03 — Topic 1 Question 999

Question

A company is creating a prototype of an ecommerce website on AWS. The website consists of an Application Load Balancer, an Auto Scaling group of Amazon EC2 instances for web servers, and an Amazon RDS for MySQL DB instance that runs with the Single-AZ configuration. The website is slow to respond during searches of the product catalog. The product catalog is a group of tables in the MySQL database that the company does not update frequently. A solutions architect has determined that the CPU utilization on the DB instance is high when product catalog searches occur. What should the solutions architect recommend to improve the performance of the website during searches of the product catalog?

Accepted Answer

Correct answer: B. The correct answer is B. Option B: Implement an Amazon ElastiCache for Redis cluster to cache the product catalog. Use lazy loading to populate the cache. Amazon ElastiCache provides in-memory caching (Redis/Memcached) to reduce latency and offload the database.
