AWS Certified Solutions Architect – Associate (SAA-C02) — Question 74

A company is hosting multiple websites for several lines of business under its registered parent domain. Users accessing these websites will be routed to appropriate backend Amazon EC2 instances based on the subdomain. The websites host static webpages, images, and server-side scripts like PHP and
JavaScript.
Some of the websites experience peak access during the first two hours of business with constant usage throughout the rest of the day. A solutions architect needs to design a solution that will automatically adjust capacity to these traffic patterns while keeping costs low.
Which combination of AWS services or features will meet these requirements? (Choose two.)

Answer options

Correct answer: C, D

Explanation

The correct options are C and D. The Application Load Balancer (C) is ideal for routing traffic based on subdomains and can handle the dynamic nature of web traffic. Amazon EC2 Auto Scaling (D) automatically adjusts the number of EC2 instances based on traffic patterns, ensuring cost efficiency by scaling down during off-peak hours. The other options do not provide the necessary features for automatic scaling and traffic routing required for this scenario.
