Layer 3 the network layer.

sorry to double post but i have tons of questions.... like 40 or so...

3.) Which type of address is 192.168.170.112/28?

a host address
b subnetwork address
c broadcast address
d multicast address

4.) A computer technician is asked to make a network cable. One end of the cable is pinned as a 568A and the other as a 568B. For what purposes can this cable be used? (Choose two.)

a to connect a router to a switch
b to connect a switch to a switch
c to connect a host to a switch
d to connect a hub to a switch
e to connect a router to a hub
f to connect a host to a hub

192.168.170.112 you can write it as above(in order to understand the whole thing):

192.168.170.0111000 ok?

now count 28 bits to see where the mask ends:

192.168.170.0111|0000 (please observe the line after the ases) ok ?

now because all the host portion is zeros (0000) this is a network address.
You can't asign it in any host.

For exampe 192.168.170.113/28 is a valid ip of the network 192.168.170.112/28

4)''as a 568A and the other as a 568B'' means that the cable is crosscable and you use it to connect same devices such as B and D.

you may not understand option D.

there is a big possibility all the above to be crap ( i have not my ccna yet!)

good luck

Read a book! I cant believe your studying routing and you cant find out what layer it uses.....
