11. (5 points) From the below output answer the questions below.

ROUTER#show interface

Ethernet 0 is up, line protocol is up

Hardware is MCI Ethernet, address is 0000.0c00.750c (bia 0000.0c00.750c)

12. (4 Points) Why is it important to put on a Banner when configuring a Cisco device?

13. (4 Points) What is the difference between “show interface” and “show ip interface brief” commands?

14. (4 Points) What is the pinout positions of a CAT5 straight through cable and a CAT5 crossover cable.

15. (20 Points) Use the below mentioned parameters to setup the networks that will be needed. Please list the (i) networks used in each floor of each building that has an equal amount of hosts on each floor; (ii) the subnet mask that will be used;

(HINT: There are a ton of IP addresses available and setting it up for documentation will work well.)
