Questions on Scenario

1 If this is all the information that you have, what IOS do you expect will be loaded when the user reloads Nova?

2 Examine the following command output in Example 2-10, taken immediately before the user is going to type the reload command. What IOS do you expect will be loaded?

Example 2-10 show ip route on Nova

Nova#show

3 Now examine the following show flash command in Example 2-11, which was issued immediately after the show ip route command in Example 2-10, but before the user issued the reload command. What IOS do you think would be loaded in this case? Example 2-11 show flash on Router Nova Nova#show flash

4096K bytes of flash memory sized on embedded flash. File name/status 0 c2500-j-l.111-3.bin [682680/4194304 bytes free/total]

4 Now examine the configuration in Example 2-12. Assume that there is now a route to 134.141.88.0 and that the file c2500-j-l.111-9.bin is an IOS image in Flash memory. What IOS do you expect will be loaded now?

Example 2-12 show running-config on Router Nova hostname Nova banner # This is the router in Nova Sibiersk; Dress warmly before entering! #

boot system tftp c2500-js-113.bin 134.141.88.3

boot system flash c2500-j-l.111-9.bin

enable password cisco

interface Serial0 ip address 134.141.12.2 255.255.255.0

interface Serial1 ip address 134.141.23.2 255.255.255.0

interface Ethernet0 ip address 134.141.2.2 255.255.255.0
