TFTP Protocol

A.

TFTP (Trivial File Transfer Protocol) is a simple protocol used to transfer files over a network. It is a lightweight protocol and is widely used in network devices such as routers, switches, and firewalls for software upgrades and backups.

Now, let's look at the statements one by one:

A. The client is unable to get a directory listing from the server. This statement is true. TFTP does not support directory browsing. The client needs to know the exact file name and path to access a file on the server. There is no provision for listing the contents of a directory.

B. The client is unable to create a new file on a server. This statement is also true. TFTP does not provide any mechanism for creating new files on the server. The client can only read or write existing files.

C. The client needs to log in with a username and password. This statement is false. TFTP does not have any authentication mechanism. Any client can connect to a TFTP server and access files without providing any username or password.

D. The client needs to log in using "anonymous" as a username and specifying an email address as a password. This statement is partially true. Some TFTP servers allow anonymous access, where the client can use "anonymous" as the username and provide an email address as the password. However, this is not a standard requirement for TFTP clients.

In summary, options A and B are true statements about TFTP, while options C and D are false or partially true.
