Question

1. Place a check mark beside the statements that are correct regarding an Ethernet MAC address.

_ The left-most 24 bits in an Ethernet Mac address are the vendor's code number.

_ A vendor can have only one vendor code.

_ An Ethernet MAC address is 48 bits long.

_ The right-most 28 bits identify which host is on the Ethernet network and these bits must be unique on the Ethernet network segment.

2. Explain how IP and ICMP work together?

3. Provide your own well written and brief definition for each of the following terms:

- Soft state

- Next hop forwarding

4.Explain in specific step-by-step detail (not more than 1000 words), the process that Jack’s computer will use to obtain the MAC address of Jill’s computer. The computers are using TCP/IP networking and are on the same local Ethernet network. Jack’s computer already knows the IP address of Jill’s computer.

Explanation / Answer

Solution:

1 and 2 is done, please repost others.

1)

All the statements are true

Explanation:

Divide the packet into one 1220 octet fragment (1200 data octets and 20 octets of header) and one 200 octet fragment (180 octets of data and 20 octets of header).

2)

When you send data from one device to another remote device, the IPv4 Datagram often travels through one or morerouters. There can be errors at routers while they try to forward the IPv4 Datagram to its final destination. The Internet Control Message Protocol (ICMP) protocol is used to report problems with delivery of IPv4 Datagrams within an IPv4network. ICMP is also used for other diagnosis and troubleshooting functions.

An Internet Control Message Protocol (ICMP) packet header is 8 Bytes long. The first four bytes always have the same meaning, and the contents of the remaining four depend on the ICMP packet type. An ICMP header follows the IP header in an IP datagram packet and Internet Control Message Protocol (ICMP) is considered to be an integral part ofIPv4.
