A) Change ip address on Serial0/0 B) Enable the interface Serial0/0
C) Check the physical connection in Serial 0/0 D) The interface looks fine in status up, problem must be somewhere else
 
Answer & Explanation Answer: C) Check the physical connection in Serial 0/0

Explanation:

In order for an interface to work properly and respond to ping requests, both Status and Protocol must be up.

Q:

The network with ip address 192.168.100.0/27 is to be used on a router. If ip subnet-zero is configured, which statement describe the resulting number of available subnets and hosts?

A) 7 usable subnets, each with 32 host addresses B) 8 usable subnets, each with 30 host addresses
C) 8 usable subnets, each with 27 host addresses D) 7 usable subnets, each with 24 host addresses
 
Answer & Explanation Answer: B) 8 usable subnets, each with 30 host addresses

Explanation:

Because subnet zero is configured and we have a class C address (192.168.100.0) then the network portion will have 3 bits so 8 subnets will be available. The rest of the bits, 5, represent the available hosts, so 2^5=32, but only 30 are available, 0 ad 31 are network and broadcast respectively.

Q:

You are the network administrator and are given the tasks to plan for the future expansion of the network. You decide to subnet the current network of 172.15.0.0. What will be the subnet mask be if every subnet has to allocate 500 hosts.

A) 255.255.0.0 B) 255.0.0.0
C) 255.255.240.0 D) 255.255.254.0
 
Answer & Explanation Answer: D) 255.255.254.0

Explanation:

Explanation: The requirement of having to allocate 500 hosts on each subnet can be achieved by the following: 2^9 = 512. So deducting the broadcast and network address we have 510 possible hosts on each subnet. We used 9 bits to allocate the hosts, this leaves us 7 bits for possible subnets. Those 7 bits in binary is 1111 1110 or 254 in decimal.

Q:

Explain the difference between the forwarding of a unicast IP packet and the forwarding of a multicast IP packet.

Answer

Unicast IP packets are forwarded based on the destination IP address. Multicast packets are forward based on the source IP address. If a multicast packet is received on the interface used to send a unicast packet back to the source, the multicast packet is forwarded to multicast neighbors. If the multicast packet is received on an interface that would not be used to send a unicast IP packet back to the source, the packet is discarded.
