PCNSE Securing Traffic and App-ID Practice Question

An engineer wants to block all peer-to-peer file sharing traffic using App-ID. What security policy action 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

Deny.

The standard action to block traffic in a security policy rule is 'deny'. 'Drop' also blocks but does not send a TCP reset, while 'deny' sends a reset. 'Allow' would permit the traffic, and 'reset-both' is a type of deny, but 'deny' is the typical best practice.

Answer analysis

Option-by-option breakdown

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

  • Drop.

    Why it's wrong here

    Drop also blocks, but is less preferred because it does not send a reset, potentially causing timeouts.

  • Reset-both.

    Why it's wrong here

    Reset-both is a specific type of deny that resets both sides; while it works, 'deny' is the standard recommended action.

  • Allow with antivirus profile.

    Why it's wrong here

    Allowing the traffic would permit it, not block it.

  • Deny.

    Why this is correct

    Correct: Deny blocks the traffic and sends a TCP reset.
