Question #: 33
Topic #: 1

[All AWS Certified SysOps Administrator - Associate Questions]

A company has an application that customers use to search for records on a website. The application's data is stored in an Amazon Aurora DB cluster. The application's usage varies by season and by day of the week.
The website's popularity is increasing, and the website is experiencing slower performance because of increased load on the DB cluster during periods of peak activity. The application logs show that the performance issues occur when users are searching for information. The same search is rarely performed multiple times.
A SysOps administrator must improve the performance of the platform by using a solution that maximizes resource efficiency.
Which solution will meet these requirements?

A. Deploy an Amazon ElastiCache for Redis cluster in front of the DB cluster. Modify the application to check the cache before the application issues new queries to the database. Add the results of any queries to the cache.
B. Deploy an Aurora Replica for the DB cluster. Modify the application to use the reader endpoint for search operations. Use Aurora Auto Scaling to scale the number of replicas based on load.
C. Use Provisioned IOPS on the storage volumes that support the DB cluster to improve performance sufficiently to support the peak load on the application.
D. Increase the instance size in the DB cluster to a size that is sufficient to support the peak load on the application. Use Aurora Auto Scaling to scale the instance size based on load.

B. Caching will not solve the performance issue in this scenario, as the same search is rarely performed multiple times. Thus read replicas will be better.

Selected Answer: A

implementing a caching layer with Amazon ElastiCache for Redis provides a scalable, cost-effective way to improve application performance by reducing database load, especially for read-heavy operations like searches. This approach addresses the core challenge of managing variable load efficiently.

A is wrong because there is no need for caching as the same search is rarely performed multiple times.

wrong: here is why: "While adding Aurora Replicas and using the reader endpoint for search operations can distribute the read load and improve performance, this solution primarily increases database capacity rather than reducing unnecessary loads. It's more cost-intensive and may still face bottlenecks during unprecedented spikes in demand, as the underlying issue of inefficient query processing during peak times isn't directly addressed."

BBBBB is the right answer in this case because caching with Elasticache for Redis will not help resolve the issue since the same search is rarely performed multiple times.
