A network administrator configures a router with the command sequence:
R1(config)# boot system tftp://c1900-universalk9-mz.SPA.152-4.M3.bin R1(config)# boot system rom
What is the effect of the command sequence?
- On next reboot, the router will load the IOS image from ROM.
- The router will copy the IOS image from the TFTP server and then reboot the system.
- The router will load IOS from the TFTP server. If the image fails to load, it will load the IOS image from ROM.
- The router will search and load a valid IOS image in the sequence of flash, TFTP, and ROM.
Answers Explanation & Hints: The boot system command is a global configuration command that allows the user to specify the source for the Cisco IOS Software image to load. In this case, the router is configured to boot from the IOS image that is stored on the TFTP server and will use the ROMmon imagethat is located in the ROM if it fails to locate the TFTP server or fails to load a valid image from the TFTP server.
