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.

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.
