Practice Test 1 | AWS Certified Solutions Architect Associate | SAA-C03 | Dumps | Mock Test
A database, hosted using the AWS RDS service, is getting a lot of database queries and has now become a bottleneck for the associating application. Which action would ensure that the database is not a performance bottleneck?
A. Setup a CloudFront distribution in front of the database.
B. Setup an ELB in front of the database.
C. Setup ElastiCache in front of the database.
D. Setup SNS in front of the database.
Explanation:
Correct Answer – C
ElastiCache is an in-memory solution which can be used in front of a database to cache the common queries issued against the database. This can reduce the overall load on the database.
- Option A is incorrect because this is normally used for content distribution.
- Option B is partially correct, but you need to have one more database as an internal load balancing solution.
- Option D is incorrect because SNS is a simple notification service.
