Amazon Exam SAA-C03 Topic 4 Question 59 Discussion

Actual exam question for Amazon's SAA-C03 exam

Question #: 59
Topic #: 4

[Design High-Performing Architectures]

The customers of a finance company request appointments with financial advisors by sending text messages. A web application that runs on Amazon EC2 instances accepts the appointmentrequests. The text messages are published to an Amazon Simple Queue Service (Amazon SQS) queue through the web application. Another application that runs on EC2 instances then sends meeting invitations and meeting confirmation email messages to the customers. After successful scheduling, this application stores the meeting information in an Amazon DynamoDB database.

As the company expands, customers report that their meeting invitations are taking longer to arrive.

What should a solutions architect recommend to resolve this issue?

AAdd a DynamoDB Accelerator (DAX) cluster in front of the DynamoDB database.

BAdd an Amazon API Gateway API in front of the web application that accepts the appointment requests.

CAdd an Amazon CloudFront distribution. Set the origin as the web application that accepts the appointment requests.

DAdd an Auto Scaling group for the application that sends meeting invitations. Configure the Auto Scaling group to scale based on the depth of the SQS queue.

Show Suggested Answer

Suggested Answer: D

To resolve the issue of longer delivery times for meeting invitations, the solutions architect can recommend adding an Auto Scaling group for the application that sends meetinginvitations and configuring the Auto Scaling group to scale based on the depth of the SQS queue. This will allow the application to scale up as the number of appointment requests increases, improving the performance and delivery times of the meeting invitations.

Hmm, CloudFront might help with caching, but I'm not convinced it's the right solution here. The bottleneck seems to be with the application sending the invitations, not the web app accepting the requests.

I think we should add a DynamoDB Accelerator (DAX) cluster.

I'm not sure if adding an API Gateway will actually resolve the issue with the meeting invitations. Seems like a bit of an overkill for this use case.

Option D sounds like the most efficient solution. Scaling the application based on the SQS queue depth will ensure the meeting invitations are sent out in a timely manner as the business grows.
