This PCNSE practice question tests your understanding of manage, monitor and operate. 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.
A firewall is experiencing performance issues. The administrator wants to collect diagnostic data for TAC analysis. Which command generates a comprehensive support file?
Clue words in this question
Noticing these words before you look at the options changes how you read each choice.
Clue: "which command"
Why it matters: Tests specific CLI syntax. Recall the exact command and its required context — near-synonyms and partial matches are common distractors.
debug system dump
Why wrong: This is used for debugging specific issues, not for general support.
show system resources
Why wrong: This shows real-time resource usage but does not generate a file.
show log system
Why wrong: This displays system logs but does not generate a file for TAC.
generate tech-support file
This creates a support file in the opt directory.
Answer choices
Answer the question above first, then reveal the full breakdown to understand why each option is right or wrong.
Correct answer & explanation
generate tech-support file
The 'generate tech-support file' command collects a comprehensive archive of system logs, configuration, resource utilization, and diagnostic data into a single file, which is the standard method for providing TAC with the necessary information to analyze performance issues. This command is specifically designed for troubleshooting and support scenarios, unlike other commands that only capture partial or real-time data.
Key principle: Answer the scenario, not the keyword: identify the specific constraint before choosing the most familiar-sounding option.
Answer analysis
For each option: why learners choose it and why it is or isn't the right answer here.
debug system dump
Why it's wrong here
This is used for debugging specific issues, not for general support.
show system resources
Why it's wrong here
This shows real-time resource usage but does not generate a file.
show log system
Why it's wrong here
This displays system logs but does not generate a file for TAC.
generate tech-support file
Why this is correct
This creates a support file in the opt directory.
Clue confirmation
The clue word "which command" in the question point toward this answer.

Common exam traps
Palo Alto Networks often tests the distinction between commands that provide real-time snapshots (like 'show system resources') versus commands that generate a comprehensive diagnostic archive (like 'generate tech-support file'), leading candidates to mistakenly choose a command that only shows current state rather than the full dataset needed for TAC analysis.
Trap categories for this question
Command / output trap
This shows real-time resource usage but does not generate a file.
Detailed technical explanation
The 'generate tech-support file' command creates a tarball (.tgz) containing outputs from multiple CLI commands (e.g., 'show system info', 'show running config', 'show log system', 'show session all'), along with system logs, crash dumps, and packet captures if available. This file is typically uploaded to the management interface or exported via SCP/HTTP, and TAC uses it to correlate performance issues with specific configurations or events, such as session table exhaustion or high CPU from policy lookups.
Key takeaway
Answer the scenario, not the keyword: identify the specific constraint before choosing the most familiar-sounding option.
Real-world example
A practitioner preparing for the PCNSE exam encounters this exact type of scenario on the job. The correct answer here is not the most general option — it is the best answer for the specific constraint described. Answer the scenario, not the keyword: identify the specific constraint before choosing the most familiar-sounding option. Real exam questions reward reading the full scenario before eliminating options, because the constraint defines which answer fits.
