PCNSE Troubleshoot Practice Question

Exhibit

admin@PA-5000> show session id 12345
Session ID: 12345
Source IP: 10.1.1.100
Destination IP: 203.0.113.50
Application: web-browsing
State: ESTABLISHED
From Zone: trust
To Zone: untrust
Rule: allow-web

Refer to the exhibit. A user at 10.1.1.100 is browsing the internet. The session is established. However, the user reports that the page is not loading completely. What could be the issue?

⚠ Common exam trap

Palo Alto Networks often tests the nuance that a session being 'established' does not guarantee full application functionality; candidates mistakenly assume that if the session is up, all traffic is passing, but App-ID misclassification can cause partial content delivery.

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 firewall might be incorrectly identifying the application as web-browsing when it is something else

When a firewall incorrectly identifies an application, it may apply the wrong App-ID-based policy, potentially blocking or failing to allow all required subcomponents of the traffic (e.g., embedded objects, scripts, or secondary connections). In this scenario, the session is established but the page does not load completely, which is a classic symptom of the firewall misclassifying the application as 'web-browsing' (HTTP/HTTPS) when it is actually a more complex application (e.g., a web application using non-standard ports or dynamic content). The firewall then enforces the policy for 'web-browsing', which may not permit the necessary additional flows or decryption, causing partial loading.

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 traffic is being blocked because the 'From Zone' is trust

    Why it's wrong here

    The session is allowed; zone is correct.

  • The session is being denied by a different rule

    Why it's wrong here

    The session shows rule allow-web, so it is allowed.

  • The firewall might be incorrectly identifying the application as web-browsing when it is something else

    Why this is correct

    Application misidentification can cause partial loading if the firewall blocks embedded objects.

  • The session is not being logged correctly

    Why it's wrong here

    Logging is not relevant to page loading.
