Implementing Cisco Secure Access Solutions (SISAS, legacy) — Question 23

The NAC Agent v4.9.x uses which ports and protocols to communicate with an ISE Policy Service Node?

Answer options

• A. tcp/8905, http/80, ftp/21
• B. tcp/8905, http/80, https/443
• C. udp/8905, telnet/23, https/443
• D. udp/8906, http/80, https/443

Correct answer: B

Explanation

The correct answer is B, as the NAC Agent v4.9.x specifically uses tcp/8905 for communication, along with http/80 and https/443 for secure and non-secure web traffic. Options A and C include incorrect ports or protocols that do not align with the NAC Agent's requirements, while option D incorrectly specifies udp/8906, which is not used by the NAC Agent.
