An organization runs a consumer-facing website on AWS. The Amazon EC2-based web fleet is load balanced using the AWS Application Load Balancer; Amazon
Route 53 is used to provide the public DNS services.
The following URLs need to server content to end users:
test.example.com
web.example.com
example.com
Based on this information, what combination of services must be used to meet the requirement? (Choose two.)

Answer options

• A. Path condition in ALB listener to route example.com to appropriate target groups.
• B. Host condition in ALB listener to route *.example.com to appropriate target groups.
• C. Host condition in ALB listener to route example.com to appropriate target groups.
• D. Path condition in ALB listener to route *.example.com to appropriate target groups.
• E. Host condition in ALB listener to route $$.example.com to appropriate target groups.

Correct answer: A, C

Explanation

The correct answers are A and C because a path condition routing example.com is necessary to direct traffic accurately for that specific domain, while a host condition for example.com ensures requests to that domain are sent to the right target groups. Options B, D, and E are not suitable as they either misconfigure the domain routing or use incorrect wildcard patterns that don't apply to the specified requirements.
