This PCNSE practice question tests your understanding of troubleshoot. The scenario asks you to isolate a root cause — eliminate options that address a different problem before choosing. After answering, compare your reasoning against the explanation and wrong-answer breakdown below. Once you have made your selection, read the full explanation to reinforce the concept and understand why each distractor is designed to mislead on exam day.
After upgrading Panorama to a newer version, a configuration push to a managed firewall fails with the error 'Commit failed: template validation error.' Which of the following should be checked first?
Clue words in this question
Noticing these words before you look at the options changes how you read each choice.
Clue: "first"
Why it matters: Order matters here. You are being tested on which action comes before the others — not which action is generally useful.
Answer the question above first, then reveal the full breakdown to understand why each option is right or wrong.
Correct answer & explanation
✓
Verify that the firewall's PAN-OS version is supported by the Panorama version.
Option A is correct because template validation errors often indicate that the version of the template or device group configuration is incompatible with the firewall's PAN-OS version. Options B, C, and D are less likely to be the root cause of a template validation error.
Key principle: Authentication proves identity; authorization controls what that identity can do after login. Both must work for full privileged access.
Answer analysis
Option-by-option breakdown
For each option: why learners choose it and why it is or isn't the right answer here.
✗
Ensure that the administrator account has superuser privileges.
Why it's wrong here
Administrator privileges affect what changes can be made, but template validation errors are not privilege-related.
✓
Verify that the firewall's PAN-OS version is supported by the Panorama version.
Why this is correct
Incompatible versions between Panorama and firewalls can cause template validation failures during push.
Clue confirmation
The clue word "first" in the question point toward this answer.
Related concept
Authentication checks who the user is.
✗
Check that the firewall is connected to the internet for cloud services.
Why it's wrong here
Internet connectivity is not required for template validation; it is needed for cloud services but not for commit/push.
✗
Review the system logs on the firewall for disk space errors.
Why it's wrong here
Disk space errors would typically appear as commit failures, not template validation errors.
Common exam traps
Common exam trap: authentication is not authorization
Logging in proves the user can authenticate. It does not automatically mean the user is allowed to enter privileged or configuration mode. Watch for AAA authorization, privilege level and command authorization details.
Detailed technical explanation
How to think about this question
This kind of question is testing the difference between identity and permission. A user may successfully log in to a router because authentication is working, but still fail to enter configuration mode because authorization is missing, misconfigured or mapped to a lower privilege level.
KKey Concepts to Remember
Authentication checks who the user is.
Authorization controls what the user is allowed to do after login.
Privilege levels affect access to EXEC and configuration commands.
AAA, TACACS+ and RADIUS can separate login success from command access.
TExam Day Tips
→Do not assume successful login means full administrative access.
→Look for words such as cannot enter configuration mode, privilege level, authorization or command access.
→Separate login problems from permission problems before choosing the answer.
Key takeaway
Authentication proves identity; authorization controls what that identity can do after login. Both must work for full privileged access.
Real-world example
How this comes up in practice
A small business has 20 workstations on the 192.168.1.0/24 network and one public IP from its ISP. The router uses PAT (NAT overload) so all 20 devices share one public address using different source ports. NAT questions test whether you understand the four address terms and which direction each translation applies.
What to study next
Got this wrong? Here's your next step.
Review Cisco AAA concepts — authentication, authorization, and accounting. Study privilege levels (0–15), command authorization under TACACS+, and how RADIUS differs. Then practise related PCNSE questions on access control and AAA configuration.

What is the correct answer to this question?
The correct answer is: Verify that the firewall's PAN-OS version is supported by the Panorama version. — Option A is correct because template validation errors often indicate that the version of the template or device group configuration is incompatible with the firewall's PAN-OS version. Options B, C, and D are less likely to be the root cause of a template validation error.
What should I do if I get this PCNSE question wrong?
Review Cisco AAA concepts — authentication, authorization, and accounting. Study privilege levels (0–15), command authorization under TACACS+, and how RADIUS differs. Then practise related PCNSE questions on access control and AAA configuration.
Are there clue words in this question I should notice?
Yes — watch for: "first". Order matters here. You are being tested on which action comes before the others — not which action is generally useful.
What is the key concept behind this question?
Authentication checks who the user is.
