Cisco help...
1 Which item is a commonly used metric?
Hop Count
2 What is a solution to the problem of routing loops resulting from incorrect updates?
Count to infinity
3 Which IOS command turns off the translation of domain names to IP addresses?
no ip domain-name lookup
4 What is the correct sequence of initialization for a router that has a configuration file?

5 Which statement is true of the count to infinity problem in routing loops?
It is caused by the split horizon problem.

Didn't have a floppy disk at school to use, so this was the first place I thought to put it.
If anyone wants to help answer some of them, feel free. It'll help in my studying.
