1. R2 is now set to be the DHCP server to provide IP address for all PC1 to PC6. The first 15 usable IP
addresses of the four networks are reserved for static IP addresses. Use the pool name LAN_A for the
network 10.0.0.0, LAN_B for the network 11.0.0.0 and LAN_C for the network 12.0.0.0. Also include
default gateway and DNS server in the DHCP assignment.
a. Besides the first 15 usable IP addresses of each network, there is one more IP address should be
excluded from DHCP pool based on the information given. What is it?
b. Write the commands on R2 to set up the DHCP server based on the requirement. Also consider
part (i) answer.
c. Assume your command typed on R2 is correct, it is found that not all PCs can get the IP
addresses from DHCP.
i. Which PCs cannot get the IP address?
ii. What is the reason with this issue from the lab experience?
iii. Write down commands to solve the problem.
2. Assume all PC can get the IP address from DHCP server already. On PC2, you ping PC4’s IP
address and the ping is successful. The following shows the mac address table of S2.
Mac Address Table
-----------------------------------------------------------------
Vlan Mac Address Type Ports
------ ------------------- -------------- --------
1 0090.0c24.5902 DYNAMIC Fa0/1
1 0060.4713.a305 DYNAMIC Fa0/3
a. Which command on the switch is able to show the above table?
b. Which PC or router interface would have the MAC address of “0090.0c24.5902”?
c. Which PC or router interface would have the MAC address of “0060.4713.a305”?
d. Assume ARP table of PC6 is empty. After pinging from PC6 to PC2, what entry should be
added to PC6’s ARP table? (You may just refer to which PC or which router interface)
e. What is the command to show ARP table in R1?
f. What is the maximum number of entries that PC5’s ARP table can have if all PC
communicate with each other?

3. A student is using PCA to ping PCB and see whether PCB is reachable or not. Wireshark is used to
capture the traffic in the process. The following diagram shows the result from Wireshark. Please
answer the sub questions based on the diagram.
a. What are the IP addresses for PCA and PCB?
b. Which devices should have the MAC addresses 00:06:25:da:af:73 ?
c. What should be done to show ICMP traffic only in the live capture window?
d. Assume all ICMP records are generated from one command. What is the command issued on
PCA command prompt?
