PCNSA Decryption and Monitoring Practice Question

No GlobalProtect configured

Refer to the exhibit. A security analyst notices that URL filtering is blocking some requests, but decryption is working. What can be concluded about the traffic that is being decrypted?

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 URL filtering profile is applied to the same rule that enables decryption.

The URL filtering statistics show total requests and blocked counts, but decryption statistics show 1200 sessions decrypted. The exhibit does not provide a direct correlation between decrypted sessions and URL filtering. However, since URL filtering inspects HTTP/HTTPS traffic, decryption enables it to see encrypted payloads. The blocked URLs (malware, spyware) likely come from decrypted sessions.

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 URL filtering profile is applied to the same rule that enables decryption.

    Why this is correct

    Typically, URL filtering is applied via security policy rules. The fact that decryption and URL filtering are both active suggests they are configured in the same rule, allowing URL filtering to inspect decrypted traffic.

  • The firewall is decrypting traffic but not inspecting it for threats.

    Why it's wrong here

    The URL filtering statistics show blocked requests, indicating inspection is happening.

  • All decrypted traffic is inspected by URL filtering.

    Why it's wrong here

    While decryption enables URL filtering to inspect encrypted traffic, the exhibit does not confirm that all decrypted traffic is subject to URL filtering; there could be other profiles.

  • GlobalProtect is required for decryption to work.

    Why it's wrong here

    GlobalProtect is not related to decryption; the exhibit shows no GlobalProtect configured, yet decryption works.
