Final Answer:
D. copy tftp flash command loads a new version of the Cisco IOS into a router. You are indicating that you want to copy a file from a TFTP server to the flash memory of the router, thereby updating the Cisco IOS version by pressing this command.
Explanation:
The correct command to load a new version of the Cisco IOS (Internetwork Operating System) into a router is "copy tftp flash."
Here's the breakdown of the command and its purpose:
copy: This keyword is used to initiate the copying or transferring of files.
tftp: This specifies the source protocol, which is Trivial File Transfer Protocol. TFTP is often used to transfer files between devices on a network.
flash: This specifies the destination location on the router's flash memory, where the new version of the Cisco IOS will be stored.
So, when you use the command "copy tftp flash," you are indicating that you want to copy a file from a TFTP server to the flash memory of the router, thereby updating the Cisco IOS version.
The other options (A, B, and C) involve variations of the command or incorrect syntax for transferring files, and they are not suitable for updating the Cisco IOS on the router.
Therefore, the correct command for loading a new version of the Cisco IOS into a router is "copy tftp flash."
