Intro to Module 7

What is the purpose of Ethernet Encapsulation?

• a) To convert TCP/IP messages to serial data
• b) To provide communication with serial devices
• c) To connect terminal servers to the Ethernet network
• d) All of the above

What is the function of a terminal server?

• a) To encapsulate Ethernet messages
• b) To convert serial data to TCP/IP messages
• c) to remotely access desktop apps installed on that server
• d) To establish communication with Ethernet devices

What is the role of the Logical Link Control (LLC) sublayer in the data link layer?

• a) It manages communications between devices over a single link of a network.
• b) It controls access to the network media.
• c) It encapsulates data into frames for transmission.
• d) It provides error detection and correction mechanisms.

Which organization has subdivided the data link layer into Logical Link Control (LLC) and Media Access Control (MAC) sublayers?

• a) IEEE (Institute of Electrical and Electronics Engineers)
• b) IETF (Internet Engineering Task Force)
• c) ISO (International Organization for Standardization)
• d) ITU (International Telecommunication Union)

What is the function of the Media Access Control (MAC) sublayer in the data link layer?

• a) It manages communications between devices over a single link of a network.
• b) It controls access to the network media.
• c) It encapsulates data into frames for transmission.
• d) It provides error detection and correction mechanisms.

What is the responsibility of the MAC sublayer in the data link layer?

• a) Data encapsulation and accessing the media.
• b) Error detection and correction.
• c) Logical communications between devices over a single link.
• d) Controlling access to the network media.

What information is included in the Ethernet frame for data delivery?

• a) Source and destination IP address.
• b) Source and destination MAC address.
• c) Source and destination port number.
• d) Source and destination network address.

In Ethernet LANs with full-duplex communications, what is the role of the MAC sublayer?

• a) Error detection and correction using CSMA/CD.
• b) Logical communications between devices over a single link.
• c) Controlling access to the network media.
• d) No access control required for full-duplex communications.
