AWS Certified Advanced Networking – Specialty (ANS-C00) — Question 144

You have a website hosted on EC2 that is not serving web pages. You have ensured that the server is running and the site is configured properly. What could be the problem?

Answer options

• A. Your NACL does not allow port 80 outbound.
• B. Your NACL does not allow ports 1024 גˆ’ 65535 outbound.
• C. Your NACL does not allow ports 1024 גˆ’ 65535 inbound. D. Your security group does not allow outbound traffic.

Correct answer: B

Explanation

The correct answer is B because if the NACL restricts outbound traffic on ports 1024 - 65535, it would prevent the website from responding to requests. Options A and C are incorrect as they pertain to specific port ranges that do not affect general web traffic. Option D is also incorrect because the issue lies with NACL settings, not the security group.
