Question

Capture the communication and find TFTP port used for communication.

a) Port 21
b) Port 53
c) Port 69
d) Port 80

Answer 1

The port used for TFTP communication is Port 69, which is simpler and lacks authentication compared to FTP which uses Port 21.

Step-by-step explanation:

The TFTP (Trivial File Transfer Protocol) port used for communication is Port 69. Unlike FTP, which uses Port 21, TFTP is a simpler file transfer protocol with no authentication, used primarily for transferring configurations or boot files to network equipment. Network administrators and cybersecurity professionals need to know how to capture and analyze network traffic to identify the ports in use. Tools like Wireshark can be used to capture network traffic and filter down to the TFTP protocol to observe the port being utilized in real-time.
