Question:
Which requirement should be checked before a network administrator performs an IOS image upgrade on a router?

  • The desired IOS image file has been downloaded to the router.
  • There is sufficient space in flash memory.
  • The old IOS image file has been deleted.
  • The FTP server is operational.

Explanation: Before an upgrade process starts, the user must make sure that there is sufficient space in the flash to host the new IOS image file. An old IOS file does not have to be deleted as long as there is sufficient space available for the new IOS file. FTP is not supported for the IOS upgrading process. Instead, a TFTP server is used. The new IOS image should be downloaded and loaded to the TFTP server.
