An IT consultant is working for a large financial company. The role of the consultant is to help the development team build a highly available web application using stateless web servers.

In this scenario, which AWS services are suitable for storing session state data? (Select TWO.)
A . ElastiCache
B . Redshift Spectrum
C . RDS
D . Glacier
E . DynamoDB

View Answer

Answer: A,E

Explanation:

DynamoDB and ElastiCache are the correct answers. You can store session state data on both DynamoDB and ElastiCache. These AWS services provide high-performance storage of key-value pairs which can be used to build a highly available web application.

Redshift Spectrum is incorrect since this is a data warehousing solution where you can directly query data from your data warehouse. Redshift is not suitable for storing session state, but more on analytics and OLAP processes.

RDS is incorrect as well since this is a relational database solution of AWS. This relational storage type might not be the best fit for session states, and it might not provide the performance you need compared to DynamoDB for the same cost.

S3 Glacier is incorrect since this is a low-cost cloud storage service for data archiving and long-term

backup. The archival and retrieval speeds of Glacier is too slow for handling session states.
