NEWT 208 WEEK 2 QUIZ

Overview

This quiz assesses knowledge on network encapsulation methods, PPP (Point-to-Point Protocol), and cable types used in network connections. The quiz includes questions on the default encapsulation for point-to-point connections, PPP session phases, and the type of cable used for connecting similar devices at serial ports.

Question 1: Default Encapsulation on Point-to-Point Connections

The default encapsulation used on point-to-point connections is HDLC.

• Explanation: High-Level Data Link Control (HDLC) is the default protocol used for encapsulating data on point-to-point serial links. HDLC is responsible for framing data before it is transmitted over the link, ensuring that the receiving device can correctly interpret the data.

Question 2: Optional Phase in PPP Session Establishment

There are three phases to establishing a PPP session, and the one that is optional is link quality determination.

• Explanation: PPP sessions go through three phases: link establishment, authentication (optional), and network layer protocol configuration. Link quality determination is used to assess the quality of the link before establishing a session, but it is not mandatory in all cases.

Question 3: Enabling an Authentication Protocol for PPP

The command to enable an authentication protocol for PPP is PPP PAP or CHAP.

• Explanation: PPP supports two main authentication protocols: PAP (Password Authentication Protocol) and CHAP (Challenge Handshake Authentication Protocol). These protocols are used to verify the identity of the devices attempting to establish a PPP connection.

Question 4: Cable Type for Connecting Similar Devices at Serial Ports

The type of cable that allows two similar devices to attach at their serial ports is known as a null modem cable.

• Explanation: A null modem cable is used to connect two similar devices, such as two computers, directly without the need for a modem. This type of cable is often used in serial communication, where it cross-connects the transmit and receive lines between the devices.
