TFTP (Trivial File Transfer Protocol) is a simple file transfer protocol used in computer networking. It is often used to transfer firmware images and configuration files to network devices, such as routers and switches.
Let's examine each statement and determine which one is not true:
A. Communication is initiated over UDP port 69. This statement is true. TFTP uses UDP (User Datagram Protocol) as the transport protocol, and communication is initiated over UDP port 69.
B. Files are transferred using a secondary data channel. This statement is not true. Unlike FTP (File Transfer Protocol), TFTP does not use a secondary data channel for file transfer. All data is transferred over the same UDP connection used for communication.
C. Data is transferred using fixed-size blocks. This statement is true. TFTP transfers data in fixed-size blocks of 512 bytes.
D. TFTP authentication information is sent in clear text. This statement is true. TFTP does not provide any form of encryption or authentication. Authentication information, such as usernames and passwords, are sent in clear text, making it a security risk.
E. TFTP is often utilized by operating system boot loader procedures. This statement is true. TFTP is often used in boot loader procedures to transfer firmware images or configuration files to network devices during the boot process.
F. The TFTP protocol is implemented by a wide variety of operating systems and network devices. This statement is true. TFTP is a simple protocol and is implemented by a wide variety of operating systems and network devices.
Therefore, the statement that is not true is B. Files are not transferred using a secondary data channel in TFTP.
