350-501 Security and Services Practice Question

An SP is implementing CGNAT to conserve IPv4 addresses. For legal compliance, they must log all NAT translations with timestamps and source/destination information. Which CGNAT feature should be enabled?

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

NAT logging

CGNAT logging is required for compliance; it logs translation events including port allocation. ALG support handles application protocols but not logging. Port allocation is part of NAT, but logging is the specific feature for compliance.

Answer analysis

Option-by-option breakdown

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

  • Destination NAT

    Why it's wrong here

    Destination NAT is a type of NAT, not a logging feature.

  • Port block allocation

    Why it's wrong here

    Port block allocation is a method of assigning ports, not logging.

  • ALG support

    Why it's wrong here

    ALG support helps with protocols like FTP, but does not provide logging.

  • NAT logging

    Why this is correct

    NAT logging records translations for compliance purposes.
