Computer Network Quiz MCQ: Exam!

The New Connection Wizard is the correct answer because it is a Windows feature that allows users to create a dial-up connection in Windows XP. It provides a step-by-step guide for setting up the connection and configuring the necessary settings, such as the phone number and authentication details. The Device Manager is not relevant to creating a dial-up connection, as it is used for managing hardware devices. The Control Panel and Accessories may contain some networking settings, but they do not specifically provide a wizard for creating dial-up connections.

IPCP stands for Internet Protocol Control Protocol. It is the network control protocol used in PPP (Point-to-Point Protocol) to facilitate the transport of TCP/IP (Transmission Control Protocol/Internet Protocol). IPCP is responsible for negotiating and configuring the IP addresses and other IP-related parameters between the PPP client and server, allowing the transmission of TCP/IP packets over the PPP connection. IPNP and IPXCP are not valid network control protocols used in PPP.

The Serial Line Internet can use TCP/IP protocol during a dial-up session. TCP/IP is a widely used network protocol suite that enables communication between devices on the internet. It provides reliable and efficient transmission of data packets over the network. TCP/IP is the foundation of the internet and supports various applications and services. Therefore, it is a suitable choice for the Serial Line Internet during a dial-up session.

A typical ISDN PRI (Primary Rate Interface) has 23 B-channels available. B-channels are used for carrying voice or data traffic, and in ISDN PRI, there are 23 B-channels available for this purpose. The other channels in an ISDN PRI are the D-channel, which is used for signaling and control purposes, and the framing and synchronization channels. Therefore, the correct answer is 23.

The Point-to-Point Protocol (PPP) consists of several components, one of which is the Network Control Protocol (NCP). NCP is responsible for establishing and configuring network-layer protocols, such as IP or IPX, over the PPP link. It handles the negotiation and management of network-layer parameters between the two endpoints of the PPP connection. Therefore, NCP is an essential part of the Point-to-Point Protocol.

PPTP (Point-to-Point Tunneling Protocol) is a protocol used for VPN solutions. It is a widely supported protocol that allows users to establish a secure and encrypted connection to a remote network over the internet. PPTP is known for its simplicity and compatibility with various operating systems and devices. It provides authentication, encryption, and compression, making it a popular choice for VPN implementations.

The correct answer is 3389. Remote Desktop and Terminal Services use port number 3389 for communication. This port allows users to remotely access and control a computer over a network. By using this port, users can establish a remote desktop session and interact with the remote computer as if they were physically present at the machine.

PPP can use CHAP (Challenge Handshake Authentication Protocol) to authenticate a remote server. CHAP is a secure authentication method that involves a three-way handshake process. During this process, the server sends a challenge to the remote server, which responds with a hashed value of the challenge and a secret password. The server then compares the received hashed value with its own calculation to verify the authenticity of the remote server. CHAP provides a higher level of security compared to other authentication methods like PAP (Password Authentication Protocol) or KPA (Keyed-Hashing for Message Authentication).

The correct answer is PPTP control connection. PPTP (Point-to-Point Tunneling Protocol) is a protocol used to create virtual private networks (VPNs). It involves the use of a control connection to set up and manage the tunnel for PPTP. This control connection is responsible for establishing and maintaining the secure connection between the client and the server. It handles authentication, encryption, and other security-related tasks. The control connection is separate from the data tunneling, which is used for transmitting the actual data between the client and the server.

PPP (Point-to-Point Protocol) is the correct answer because it is a remote protocol that supports running many different types of network protocols over a serial link. PPP provides a standardized method for encapsulating multiple network layer protocols such as IP, IPX, and NetBEUI, allowing them to be transmitted over a serial connection. This flexibility and versatility make PPP an ideal choice for connecting remote networks and devices.

Tunneling is the correct answer because virtual private networks (VPNs) use this technology to create a secure communications channel by encapsulating and encrypting data packets within another protocol. This allows the data to be transmitted securely over the internet, protecting it from unauthorized access or interception. IP header compression and multiple network protocol support are not directly related to the security aspect of VPNs.

Using Terminal Services allows organizations to extend the life of their older workstation PCs by enabling them to connect to a more powerful server. This means that even if the individual workstations are outdated and cannot handle the latest software or applications, they can still access them through the server. This not only saves costs on purchasing new hardware but also ensures that employees can continue to work efficiently without any major disruptions.

When modem logging is enabled, the logging information for a connection is appended to a file named "modemlog_modemname.txt". This file is specific to the modem being used, as indicated by the "modemname" in the file name. Therefore, each modem will have its own separate log file to store the logging information for its connections.

Terminal Services use the RDP (Remote Desktop Protocol) to send screenshots to the client. RDP is a proprietary protocol developed by Microsoft that allows users to connect to and control a remote computer over a network. It provides a secure and efficient way to transmit graphical user interface (GUI) data, including screenshots, from the remote server to the client device. RDP is widely used for remote desktop access and virtualization solutions. NetBEUI, ICA, and TCP/IP are not specifically designed for sending screenshots in Terminal Services.

NI-1 was the first Integrated Services Digital Network (ISDN) standard to be published by the ITU. This standard was developed to provide a digital network for both voice and data communication, allowing for the integration of different services over a single network. NI-1 defined the signaling and protocol specifications for ISDN, enabling interoperability between different network equipment and facilitating the widespread adoption of ISDN technology.

TAPI stands for Telephony Application Programming Interface. It is used to include features such as call monitoring and multiple localities in application programming. TAPI provides a standard interface for applications to interact with telephony services on a computer system. It allows developers to create applications that can control and manage telephony devices, such as modems and telephones, and perform various telephony functions. Therefore, TAPI is the correct answer for this question.
