PCNSE Troubleshoot Practice Question
A network administrator wants to verify if a specific internal IP address (10.1.1.100) is being translated to a public IP when accessing the internet. Which CLI command should be used?
⚠ Common exam trap
Many exam-takers confuse viewing NAT policy configuration (which shows rules) with viewing active NAT translations (which requires session table inspection), leading them to pick 'show running nat-policy' instead of the session-based command.
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
✓
show session all filter source 10.1.1.100
The 'show session all filter source 10.1.1.100' command displays active sessions in the firewall's session table, including the source IP, destination IP, and the translated (NAT) IP addresses. This allows the administrator to verify whether the internal IP 10.1.1.100 is being NATed to a public IP when accessing the internet, as the session table shows both the pre-NAT and post-NAT source addresses.
Answer analysis
Option-by-option breakdown
For each option: why learners choose it and why it is or isn't the right answer here.
- ✗
show running nat-policy
Why it's wrong here
This shows the NAT policy configuration, not current translations.
- ✓
show session all filter source 10.1.1.100
Why this is correct
This command displays all active sessions from the specified source, including NAT source and destination translations.
- ✗
show nat rule
Why it's wrong here
This command shows NAT policy rules, not active sessions or translations.
- ✗
show address 10.1.1.100
Why it's wrong here
This is not a valid command; showing an address is not a standard CLI command on Palo Alto firewalls.
