Palo Alto Networks Certified Network Security Engineer (PCNSE) — Question 320

An administrator connected a new fiber cable and transceiver to interface Ethernet1/1 on a Palo Alto Networks firewall. However, the link does not seem to be coming up.

If an administrator were to troubleshoot, how would they confirm the transceiver type, tx-power, rx-power, vendor name, and part number via the CLI?

Answer options

• A. show system state filter sw.dev.interface.config
• B. show chassis status slot s1
• C. show system state filter-pretty sys.s1.*
• D. show system state filter ethernet1/1

Correct answer: C

Explanation

The correct command is 'show system state filter-pretty sys.s1.*' because it provides detailed information about the system's state, including the transceiver attributes. The other options either do not provide the necessary details or focus on different aspects of the system that are not relevant to confirming transceiver specifications.
