- 11.Why do network devices need two layers of addressing, Data Link Layer Address (i.e. Ethernet) and a Network Layer Address (i.e. IP Address)?
- A.
A Network Layer Address is used to forward the packet from one network segment to another network segment. The Data Link Address is used to forward the frame from one device to another within the network segment.
- B.
The IP Address can be used to forward packets to the final destination but historically Ethernet was developed first so it continues to be used for Data Link Addressing
- C.
A Data Link Layer Address is used to forward the packet from one network segment to another network segment. The Network Layer Address is used to forward the frame from one device to another within the network segment
- D.
Since MAC addresses are unique, a Data Link Layer Addresses can be used to forward frames to any destination. A Network Layer Address is logical a can only be used to send data to a destination on the same network segment
- 12.What is a LAN?
- A.
Local Area Networks are typically within a building and connect office workers to servers.

Local Area Networks are used to connect an organization's network segments which are located in different cities.
- D.
Local Area networks cover a geographic area roughly the size of a city.
- E.
None of these answers are correct.
- 13.What is Encapsulation?
- A.
It is the process of adding a protocol header and sometimes a trailer to a block of application data.
- B.
It is the process of removing the data portion of the PDU and passing it up to the next higher layer.
- C.
It is the process of obtaining a MAC addresses which corresponds to a given IP address.
- D.
It is the process of obtaining an IP addresses which corresponds to a given MAC address
- 14.What is Message Segmentation?
- A.
Segmentation is the process of breaking the application data stream into pieces or blocks of data
- B.
Segmentation is the process where devices communicate in both directions at the same time.
- C.
Segmentation is the process which allows data to be delivered to a destination on a different network.
- D.
Segmentation allows a server to determine which service the data should be directed to.
- 15.
This picture is an example of ________ Duplex communication.
- 16.How many bits and Hex digits does the MAC Address have?

48 bits (12 Hex digits)
- B.
48 bits (18 Hex digits)
- C.
MAC Addresses don't use Hex digits
- D.
24 bits (6 Hex digits)
- E.
32 bits (18 Hex digits)
- 17.What is the basic operation of an Ethernet Switch?
- A.
After a frame arrives at a switch port, the Switch looks up the destination MAC address in the MAC Address Table to determine on which port to send the frame and then sends the frame.
- B.
After a frame arrives at a switch port, the Switch looks up the destination MAC address in the Routing Table to determine on which port to send the frame and then sends the frame
- C.
After a packet arrives at a switch port, the Switch looks up the source MAC address in the MAC Address Table to determine on which port to send the frame and then sends the frame
- D.
After a frame arrives at a switch port, the Switch looks up the destination MAC address in the arp table to determine on which port to send the frame and then sends the frame
- E.
All the above are variations of the correct basic operation
- 18.What happens to an incoming frame if the Switch doesn't have an entry for the Destination Address in its MAC Address Table?
- A.
The frame is sent out all ports except the ingress port (original incoming port)
- B.
The frame is dropped until it learns the correct port from the source address of an incoming frame.
- C.
The frame is sent out all ports in an attempt to reach the destination device
- D.
The switch sends an ARP request and the device with the destination MAC address responds
- E.
Switches populate the MAC Address Table by observing the Source MAC Address of all incoming frames
- 19.How does the Switch learn on which port a device is connected?
- A.
When a device sends a frame via a Switch, the Switch reads the Source MAC Address of the frame and enters it into the MAC Address Table together with the physical port number on which the frame arrived
- B.
This is usually done by the network administrator by statically adding the information to the MAC Address Table
- C.
When a device sends a frame via a Switch, the Switch reads the Destination MAC Address of the frame and enters it into the MAC Address Table together with the physical port number on which the frame arrived.
- D.
When a device sends a frame via a Switch, the Switch reads the Source IP Address of the frame and enters it into the MAC Address Table together with the port number on which the frame arrived.

- D.
Layer 3 of the TCP/IP Model is the Transport layer whereas layer 2 of the OSI Model is the Transport layer
