Exam AWS Certified Advanced Networking - Specialty ANS-C01 topic 1 question 2 discussion

A - correct. Here's why: An Application Load Balancer (ALB) can be used to route traffic to multiple target groups based on the URL in the request. The ALB can be configured with an HTTPS listener to ensure all traffic uses HTTPS. TLS processing can be offloaded to the ALB, which reduces the load on the web server. Path-based routing rules can be used to route traffic to the correct target group based on the URL in the request. The X-Forwarded-For request header can be included with traffic to the targets, which will allow the web server to know the user's IP address and keep accurate logs for security purposes.

Answer is A

NLB is working on L4 instead of L7 (HTTPS).

A is the correct answer. ALB with HTTPS listener, and X-Forwarded-For is added by default.

I think that It's correct answer is A according to the SPOTO products.

I think that it's correcty answer is A.

ALB: TLS termination, path based listener configuration and X-Forwarded-For request header

Target group based rule

The correct answer is A. Deploy an Application Load Balancer with an HTTPS listener. Use path-based routing rules to forward the traffic to the correct target group. Include the X-Forwarded-For request header with traffic to the targets.

A & C both can be correct but the company wants highly available design so C should be correct as it provides zonal isolation. ALB does not support Zonal Isolation for HA.

ALB does not preserve client IP address therefore I believer the answer to be D.

A should be correct. For B, host routing is based on domain name, it's also could route based on URL. But we don't need listener for each domain.

A - correct.

ALB & Path based routing is the correct answer

An Application Load Balancer (ALB) can be used to meet the requirement of routing requests to multiple target groups based on the URL in the request. Path-based routing rules can be used to forward traffic to the correct target group. The ALB also supports HTTPS listener and offloads TLS processing, which meets the requirement of using HTTPS for all traffic. The X-Forwarded-For request header can be included with traffic to the targets to preserve the user's IP address for logging purposes.
