An analyst is reviewing this configuration. What is the most significant security concern?

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

The access-list does not specify source IPs, allowing any source.

Allowing any source IP is a security risk; source restriction is missing. Option A is the purpose. Option B is present (deny any). Option C is a design choice. Option E is not recommended.

Answer analysis

Option-by-option breakdown

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

  • The access-list permits all traffic to 192.168.1.100 on ports 80 and 443.

    Why it's wrong here

    Intended functionality.

  • The access-list is missing a rule to deny all other traffic.

    Why it's wrong here

    Deny any any is present.

  • The access-list only permits traffic to a single host.

    Why it's wrong here

    Design choice, not a security flaw.

  • The access-list does not specify source IPs, allowing any source.

    Why this is correct

    Best practice is to restrict source addresses.

  • The access-list should permit traffic to the entire subnet.

    Why it's wrong here

    Would widen exposure.
