Question 6 of 21

7. Your IT manager asks how to change the subnet representation on your routers to the slash value such as /24 instead of 255.255.255.0. Which command will achieve this?

Question 7 of 21

8. Which subnet is host 10.1.1.54/30 in?

Question 8 of 21

9. What is the other host address in the same subnet as 10.1.1.66/30?

Question 9 of 21

10. Which subnet is host 172.16.1.117/20 in?

Question 10 of 21

11. Your IT manager gives you the broadcast address of 172.16.47.255/20 and asks you to work out the first host for this subnet. What do you tell him?
