Question 1
As a CCNA candidate, you should master the functions of various commands. Look at the following items, some commands are listed on the left. The related roles are listed on the right in a wrong sequence. Please match them together. (Not all options are used)
Answer:
1) Router#copy tftp flash: replace the IOS image
2) Router#copy flash tftp: backup the current IOS image
3) Router#copy running-config tftp: make a backup copy of configuration in RAM
4) Router#copy running-config startup-config: make the configuration in RAM the configuration the router will use on startup
5) Router#copy tftp running-config: merge a backup configuration with the configuration in RAM
Explanation
First please notice that by saying “replace” we often mean changes to NVRAM and TFTP while saying “merge” or “add” we mean changes to RAM. Next we should review the syntax of “copy” command:
Syntax: copy
1) By default, the flash memory in a router is used to store the Cisco IOS image so the requirement “replace the IOS image” means that moving file somewhere to the flash memory. In the left columns we only have one choice which has the flash as the destination ->copy tftp flash.
2) Same explanation as above, when saying “backup the current IOS image” the flash takes the role as the source ->copy flash tftp. And “backup” means we should copy it to somewhere like tftp server, CDROM…
3) The running-config is stored in the RAM so “make a backup copy of configuration in RAM” means copy running configuration from RAM so backup server (tftp) -> copy running-config tftp
4) “copy running-config startup-config” is a very common command so no more explanation needed.
5) After solving 4 boxes above, we only have two choices left: “copy tftp running-config” & “copy flash running-config”. The bottom-right box says “merge a backup configuration” so it should be the tftp server and the command here is copy tftp running-config.
