1. What is the purpose of the address resolution protocol (ARP)? The purpose of ARP is to convert IP addresses to Ethernet addresses 2. What is the purpose of the dynamic host control protocol (DHCP)? DHCP is a method for assigning IP addresses to individual machines in an organization. The IP addresses can be assigned permanently or temporary. 3. What was the DHCP allocated source IP host address for the “Student” VM and Target VM? 172.30.0.4 – Student VM (Ubuntu)
172.30.0.8 – Target VM (Windows)
4. When you pinged the targeted IP host, what was the source IP address and destination IP address of the ICMP echo-request packet? Source: 172.30.0.2
5. Did the targeted IP host respond to the ICMP echo-request packet with an ICMP echo-reply packet? If yes, how many ICMP echo-request packets were sent back to the IP source? Yes, 8 packets.
6. Find a TCP three-way handshake for a Telnet, FTP, or SSH session. What is the significance of the TCP three-way handshake? The three way handshake is needed to establish a reliable connection between computers. The handshake allows client to server communications to agree on security protocols for security and reliability. 7. What was the SEQ# of the initial SYN TCP packet and ACK# of the SYN ACK TCP packet? `The SEQ# is 0 for the initial SYN TCP and the SYN ACK is ACK# 1 8. During the instructor’s Telnet session to LAN Switch 1 and LAN Switch 2, what was the captured terminal password for LAN Switch 1 and LAN Switch 2? There captured password was “cisco” for both LAN switches. 9. When the instructor used SSH to remotely access a Cisco router, were you able to see the terminal password? Why or why not? No, the communication was encrypted along with the password. 10. What other IP packets are on the VLAN and Ethernet LAN segment? How can these other IP packets provide additional clues or information about the logical IP routing and IP addressing schema? Packets provide information...
