Exam AWS Certified Solutions Architect - Associate SAA-C03 topic 1 question 813 discussion

Exam question from Amazon's AWS Certified Solutions Architect - Associate SAA-C03
Question #: 813
Topic #: 1
[All AWS Certified Solutions Architect - Associate SAA-C03 Questions]

A solutions architect runs a web application on multiple Amazon EC2 instances that are in individual target groups behind an Application Load Balancer (ALB). Users can reach the application through a public website.

The solutions architect wants to allow engineers to use a development version of the website to access one specific development EC2 instance to test new features for the application. The solutions architect wants to use an Amazon Route 53 hosted zone to give the engineers access to the development instance. The solution must automatically route to the development instance even if the development instance is replaced.

Which solution will meet these requirements?

  • A. Create an A Record for the development website that has the value set to the ALB. Create a listener rule on the ALB that forwards requests for the development website to the target group that contains the development instance.
  • B. Recreate the development instance with a public IP address. Create an A Record for the development website that has the value set to the public IP address of the development instance.
  • C. Create an A Record for the development website that has the value set to the ALB. Create a listener rule on the ALB to redirect requests for the development website to the public IP address of the development instance.
  • D. Place all the instances in the same target group. Create an A Record for the development website. Set the value to the ALB. Create a listener rule on the ALB that forwards requests for the development website to the target group.

Both A and C look correct but with the C you pass through the ALB to be redirected to a public IP (so go outside) to come back again through this public IP which is not ideal. The answer A is much cleaner and simplier with a dedicated target group and a listener rule pointing it.

B: Directly using a public IP address ties the A Record to a specific instance, which is not ideal since replacing the instance would require manually updating the Route 53 record. C: Redirecting to a public IP address of the development instance is similar to option B, and would also require manual updates if the instance changes.

Public IP is not permanent, so definitely not B and C
