SNCF — Securing Networks with Firepower — Question 35

An administrator is attempting to remotely log into a switch in the data center using SSH and is unable to connect. How does the administrator confirm that traffic is reaching the firewall?

Answer options

• A. by performing a packet capture on the firewall
• B. by attempting to access it from a different workstation
• C. by running Wireshark on the administrator's PC
• D. by running a packet tracer on the firewall

Correct answer: A

Explanation

The correct answer is A, as performing a packet capture on the firewall directly allows the administrator to see if the SSH traffic is reaching the firewall. Option B may not provide conclusive evidence about the traffic reaching the firewall, while option C only monitors local traffic and does not confirm if the packets are hitting the firewall. Option D, running a packet tracer, is useful for simulating traffic but does not actually capture live traffic, making it less effective for this situation.
