2. Which layer of the TCP/IP model processes requests from hosts to make sure a connection is made to the appropriate port? i. Application Layer
3. What are well known ports? i. Also known as “reserve ports”, which are ports 1 – 1023 that are reserved by ICANN
4. Identify the port numbers for the following applications. a. Telnet – 23 b. HTTP – 80 (Hypertext Transfer Protocol) c. FTP – 20, 21 (File Transfer Protocol) d. DNS – 53 (Domain Name Server) e. DHCP – 67, 68 (Dynamic Host Control Protocol)
5. Define the purpose of a connection oriented protocol. Give an example. i. Establishes the network connection, manages the data transfer, and terminates the connection. I. Connection Oriented Protocol – Establishes a network connection, manages the delivery of data, and terminates the connection. ii. The TCP (Transport Control Protocol) protocol within the TCP/IP transport layer. I. TCP protocol establishes a set of rules or guidelines for establishing the connection. 6. What three packets are exchanged between two hosts when establishing a TCP connection? i. SYN – (Synchronizing Packet) ii. SYN ACK – (Synchronizing Acknowledgement Packet) iii. ACK– (Acknowledgement Packet)
10. What is a connectionless protocol? Give an example. i. UDP (User Datagram Protocol) Protocol is a connectionless protocol. ii. UDP packets are transported over the network without a connection being established and without any acknowledgment that the data packets arrived at the destination.
14. What important networking –troubleshooting tool is part of ICMP, and how does it test a network connection? i. Ping – Packet Internet Groper I. The ping command uses a series of echo requests, and the networking device receiving the echo requests responds with a series of echo replies to test a network connection.
