Answer: 192.168.200.31Explanation:User the " show ip interface
brief" command
User the " show interface fa0/1" command
-
From the output we learn that the ip address of the
FastEthernet0/1 interface ofRouter1 is 192.168.200.23 and the
subnet mask is /2 8.-> The broadcast address of this subnetwork
is 192. 168.200.31
Answer: 512 Kbit/secExplanation:Use the " show interfaces serial
0/0" command
-
Answer: FastEthernet0/0 and Serial 0/1Explanation:User the "
show ip interface brief" commandNotice that Router1 does not have
Ethernet 0 and Se rial 0 interfaces. FastEthernet 0/1and Serial 0/0
were configured with their IP addres ses therefore only
FastEthernet 0/0and Serial0/1 have not had any configurations appli
ed.
-
Answer: 14Explanation:The mask address of interface Fa0/1 of
Router1 is / 28, which has four 0 bits (11111111.1111 1111.1111
1111.11110000). Therefore there are 24– 2 = 14 assignable
IPaddresses for hosts on the LAN.

Answer:Router1(conf)# interface s0/0Router1(conf-if)# no
shutdown
Explanation:User the " show ip interface brief" command
From the output, we learn that the status of Serial 0/0
interface which connects to ISProuter is currently
"administratively down". This s tatus indicates this interface
isshutting down so we need to turn it on.

(5) Configure Ethernet interface (on the right) of router
Orlando:The subnet mask of the Ethernet network 209.165.201.0 is

1111.1111 1111.1110 0000. Pay moreattention to the last bit 1
because it tells us the increment, using the formula:Increment =
2place of the last bit 1 (starts counting from 0,from right to
left), in this case increment = 25= 32.Therefore:Increment:
32Network address: 209.165.201.0Broadcast address: 209.165.201.31
(because 209.165.201.32 is the second subnetwork, so the previous

subnet).-> The second assignable host address of this subnetwork

(because 8 * 16 = 128 so 192.0.2.128 is also the network address of
