Discuss Amazon SAA-C03 Exam Topic 2 Question 11

A solutions architect is designing the architecture of a new application being deployed to the AWS Cloud. The application will run on Amazon EC2 On-Demand Instances and will automatically scale across multiple Availability Zones. The EC2 instances will scale up and down frequently throughout the day. An Application Load Balancer (ALB) will handle the load distribution. The architecture needs to support distributed session data management. The company is willing to make changes to code if needed.

What should the solutions architect do to ensure that the architecture supports distributed session data management?

AUse Amazon ElastiCache to manage and store session data.

BUse session affinity (sticky sessions) of the ALB to manage session data.

CUse Session Manager from AWS Systems Manager to manage the session.

DUse the GetSessionToken API operation in AWS Security Token Service (AWS STS) to manage the session

Suggested Answer: A

In order to address scalability and to provide a shared data storage for sessions that can be accessible from any individual web server, you can abstract the HTTP sessions from the web servers themselves. A common solution to for this is to leverage an In-Memory Key/Value store such as Redis and Memcached. ElastiCache offerings for In-Memory key/value stores include ElastiCache for Redis, which can support replication, and ElastiCache for Memcached which does not support replication.

Wait, are we seriously considering sticky sessions? That feels risky!

D? Really? That doesn’t sound like it fits the use case at all.

C seems a bit off for session management, right?

I think B could work too, but it might not be as reliable.

A is definitely the best choice for distributed session management!

I feel like Session Manager from AWS Systems Manager might not be the right fit for session data management, but I can't recall the details.

I practiced a similar question where we had to choose between different AWS services for session management, and ElastiCache seemed to be the most recommended.

I'm not entirely sure, but I think using sticky sessions with the ALB could work too, although it might not be the best for scaling.

I remember discussing how ElastiCache can be a great option for session management since it provides fast in-memory data storage.

This looks straightforward. I'll focus on clearly describing the process flow and evaluating the measurement system.

I'm a bit confused on this one. Is the NAIC Act the same as the Unfair Claims Settlement Practices Act? I'm not totally clear on the details of what qualifies as an improper practice under that law. I'll have to review my notes.

Okay, I think I've got this. The key is to identify which services have a direct connection to the site database versus using the Citrix Configuration Service (CCS) as an intermediary.

I remember we talked about how filters can be set up both through the CLI and the web interface, so I think options A and B might be correct.
