Tricky question
Hello, did you know why answer is C? Why in not B? Thanks.
My thought process is that SSH (Secure Shell) is more for remote access, whereas TFTP (Trivial File Transfer Protocol) is for transferring files, which is what you need to transfer firmware files from the FTP server to the Switch.
Source: have CCNA and had similar questions regarding upgrading firmware on switches and routers that involved using FTP.
“Most commonly used by computers (with-out user intervention) as they are booting up to request configuration files from another computer on the local network. TFTP uses UDP, whereas normal FTP uses TCP.” From ‘Network+ Guide to Networks, Eighth Edition’.
