Exam AWS Certified Solutions Architect - Associate SAA-C02 topic 1 question 819 discussion

Exam question from Amazon's AWS Certified Solutions Architect - Associate SAA-C02
Question #: 819
Topic #: 1
[All AWS Certified Solutions Architect - Associate SAA-C02 Questions]

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 appointment requests. 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?

  • A. Add a DynamoDB Accelerator (DAX) cluster in front of the DynamoDB database.
  • B. Add an Amazon API Gateway API in front of the web application that accepts the appointment requests.
  • C. Add an Amazon CloudFront distribution. Set the origin as the web application that accepts the appointment requests.
  • D. Add 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.

In the following example, I dont see any auto scaling group. But I do see the CloudFront distribution. https://aws.amazon.com/blogs/machine-learning/build-an-appointment-scheduler-interface-integrated-with-meta-using-amazon-lex-and-amazon-connect/

Selected Answer: C
Could be C. Upon confirmation by advisors on web server, appointment should be disseminated to customers at this point. No need for further escalation to SQS and app server just to send out the confirmation to customer?
