ANS-C01 Network Security, Compliance and Governance Practice Question

A company uses an AWS Network Firewall to inspect traffic between VPCs and the internet. They want to allow outbound HTTPS traffic only to specific domains. Which rule configuration should be used?

Answer choices

Why each option matters

Answer the question above first, then reveal the full breakdown to understand why each option is right or wrong.

Correct answer & explanation

✓

Create a stateful rule group with a 'pass' action for the allowed domains using domain list rule group.

Domain list rule group in AWS Network Firewall can match FQDNs. Stateful rule groups inspect traffic states. Suricata compatible rules allow custom domain matching. IP set would match by IP, not domain.

Answer analysis

Option-by-option breakdown

For each option: why learners choose it and why it is or isn't the right answer here.

  • ✗

    Create a stateless rule group with a 'forward' action for the allowed IP addresses.

    Why it's wrong here

    Stateless rules do not inspect domain names; they work on IP/port.

  • ✓

    Create a stateful rule group with a 'pass' action for the allowed domains using domain list rule group.

    Why this is correct

    Domain list rule group allows matching by domain name in stateful rules.

  • ✗

    Create a stateful rule group with a 'drop' action for all traffic and then 'pass' for the allowed domains using Suricata compatible rules.

    Why it's wrong here

    Correct approach is to use domain list rule group, not Suricata rules for simple domain filtering.

  • ✗

    Create an IP set rule group with the allowed domain IP addresses.

    Why it's wrong here

    IP set would match by IP, not domain; domains can resolve to multiple IPs.
