       network layer
       data link layer

 

Question 2. 2. (TCO 3) A physical network connection is also referred to as a _____. (Points : 4)
       logical network
       network segment
       sublayer
       media network layer

 

Question 3. 3. (TCO 3) This organization defines the open standards and protocols that apply to the data link layer. (Points : 4)
       International Organization for Standardization (ISO)
       Institute of Electrical and Electronics Engineers (IEEE)
       International Telecommunication Union (ITU)
       All of the above

 

Question 4. 4. (TCO 3) The 802.11 frame contains the _____ field. (Points : 4)
       less fragments
       protocol version
       discard
       resend

 

Question 5. 5. (TCO 3) When is a wired connection preferred to a wireless connection by an end-user device? (Points : 4)
       When the end-user device is within range of a wireless signal
       When the end-user device will run an application that requires a dedicated connection to the network
       When the end-user device only has a WLAN NIC
       When the end-user device will run an application that is delay tolerant

 

Question 6. 6. (TCO 3) Which action is taken by a Layer 2 switch when it receives a Layer 2 broadcast frame? (Points : 4)
       It drops the frame.
       It sends the frame to all ports except the port on which it received the frame.
       It sends the frame to all ports.
       It sends the frame to all ports that are registered to forward broadcasts.

       The packet will be sent directly to the destination host.
       The packet will be sent to the default gateway first, and then, depending on the response from the gateway, it may be sent to the destination host.
       The packet will first be sent to the default gateway, and then from the default gateway, it will be sent directly to the destination host.
       The packet will be sent only to the default gateway.

 

Question 8. 8. (TCO 3) Why is NAT not needed in IPv6? (Points : 4)
       The end-to-end connectivity problems that are caused by NAT are solved, because the number of routes increases with the number of nodes that are connected to the Internet.
       Any host or user can get a public IPv6 network address, because the number of available IPv6 addresses is extremely large.
       Because IPv6 has integrated security, there is no need to hide the IPv6 addresses of internal networks.
       The problems that are induced by NAT applications are solved, because the IPv6 header improves packet handling by intermediate routers.

 

Question 9. 9. (TCO 3) Compared to UDP, what factor causes additional network overhead for TCP communication? (Points : 4)
       Network traffic that is caused by retransmissions
       The identification of applications based on destination port numbers
       The encapsulation into IP packets
       The checksum error detection

 

Question 10. 10. (TCO 3) A PC is downloading a large file from a server. The TCP window is 1000 bytes. The server is sending the file using 100-byte segments. How many segments will the server send before it requires an acknowledgment from the PC? (Points : 4)
       1 segment
       10 segments
       100 segments
       1000 segments

 

Question 11. 11. (TCO 3) Which of these statements regarding UTP network cabling are true?

2 : Segment
3 : Frame
4 : Data
    Answer
     : Ethernet
     : HTTP
     : IP
     : TCP

 

Question 13. 13. (TCO 3) Describe the importance of the trailer in the Data Link layer and its implications for use on Ethernet, a "nonreliable" media. (Points : 10)
