PCNSE Practice Question: Securing Users and Applications with Authentication

An organization uses captive portal authentication. Users report that after closing the browser, they are still authenticated and can access resources without re-authenticating. How can the administrator enforce re-authentication after browser closure?

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

✓

Clear the 'allow session cookie' option in the captive portal profile.

Captive portal uses a session cookie to maintain authentication. Clearing the 'allow session cookie' option forces the user to authenticate for each new browser session. Option A is correct.

Answer analysis

Option-by-option breakdown

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

  • ✓

    Clear the 'allow session cookie' option in the captive portal profile.

    Why this is correct

    This disables the session cookie, so when the browser is closed, the session ends and re-authentication is required.

  • ✗

    Configure the authentication enforcement to require authentication for each session.

    Why it's wrong here

    Authentication enforcement is a separate setting in security policies, not directly controlling captive portal behavior.

  • ✗

    Set the session timeout to 0 in the captive portal profile.

    Why it's wrong here

    Setting timeout to 0 disables session timeout entirely, making the session last forever.

  • ✗

    Disable the 'session cookie' setting in the captive portal profile and change the authentication profile to use RADIUS.

    Why it's wrong here

    Disabling session cookie is correct, but changing the authentication profile is unnecessary.
