CCNA: Cisco Certified Network Associate — Question 188

What is a function of TFTP in network operations?

Answer options

• A. transfers IOS images from a server to a router for firmware upgrades
• B. transfers a backup configuration file from a server to a switch using a username and password
• C. transfers configuration files from a server to a router on a congested link
• D. transfers files between file systems on a router

Correct answer: A

Explanation

The correct answer is A because TFTP is primarily used to transfer IOS images for firmware updates. Option B is incorrect as TFTP does not utilize authentication methods like usernames and passwords. Option C is misleading since TFTP is not specifically designed for congested links, and option D is incorrect as TFTP is used for transferring files, not managing file systems on routers.
