Which protocol uses Token Passing in a Bus Topology?

  1. 802.1

  2. 802.2

  3. 802.3

  4. 802.4

  5. 802.5


Correct Option: D
Explanation:

To answer this question, the user needs to know the network topologies and the protocols that use them. Token Passing is a method of sharing a communication medium between network devices by passing a token among the devices. The device holding the token has the right to transmit data, and after transmission, the token is passed to the next device in the sequence. Token Passing is commonly used in Bus Topology, which is a network topology in which all devices are connected to a central cable.

Now let's go through each option and explain which protocol uses Token Passing in a Bus Topology:

A. 802.1: 802.1 is not a protocol, but rather a family of networking standards that deal with network architecture, management, and security.

B. 802.2: 802.2 is a protocol that defines the Logical Link Control (LLC) sublayer of the Data Link Layer in the OSI model. It does not use Token Passing in a Bus Topology.

C. 802.3: 802.3 is a protocol that defines the Ethernet standard, which is a common protocol used in Local Area Networks (LANs). It does not use Token Passing in a Bus Topology.

D. 802.4: 802.4 is a protocol that defines the Token Bus network, which uses Token Passing in a Bus Topology. However, it is not widely used today.

E. 802.5: 802.5 is a protocol that defines the Token Ring network, which uses Token Passing in a Ring Topology. It is used in some legacy systems but has largely been replaced by Ethernet.

Therefore, the answer is:

The Answer is: D. 802.4

What is the default port of a SMTP server?

  1. 8

  2. 21

  3. 80

  4. 25

  5. 110


Correct Option: D
  1. COM1

  2. COM2

  3. Keyboard

  4. Hard Drive Controller

  5. Display Card


Correct Option: B
Explanation:

To solve this question, the user needs to have knowledge of IRQ (Interrupt Request) and the devices that commonly use specific IRQ numbers.

IRQ is a mechanism used by devices to request the attention of the CPU. Each device in a computer system is assigned a unique IRQ number to prevent conflicts when multiple devices try to use the CPU simultaneously.

Now, let's go through each option and explain why it is right or wrong:

A. COM1: This option is incorrect. COM1 typically uses IRQ 4, not IRQ 3. Therefore, there would be no conflict between a network adapter on IRQ 3 and COM1.

B. COM2: This option is incorrect. COM2 typically uses IRQ 3, which means there could be a conflict between a network adapter on IRQ 3 and COM2. Both devices may try to use the same IRQ, leading to conflicts.

C. Keyboard: This option is incorrect. The keyboard typically uses IRQ 1 or IRQ 12, not IRQ 3. Therefore, there would be no conflict between a network adapter on IRQ 3 and the keyboard.

D. Hard Drive Controller: This option is incorrect. The hard drive controller typically uses IRQ 14 or IRQ 15, not IRQ 3. Therefore, there would be no conflict between a network adapter on IRQ 3 and the hard drive controller.

E. Display Card: This option is incorrect. The display card typically uses IRQ 9 or IRQ 11, not IRQ 3. Therefore, there would be no conflict between a network adapter on IRQ 3 and the display card.

Based on the explanations above, the correct answer is:

The Answer is: B. COM2

What is the directory service called in Netware?

  1. Active Directory

  2. Domain Name System

  3. NDS

  4. NWLink

  5. DNS


Correct Option: C

AI Explanation

To answer this question, you need to understand the different directory services used in networking.

Option A) Active Directory - This option is incorrect because Active Directory is a directory service provided by Microsoft for Windows-based networks. It is not specific to Netware.

Option B) Domain Name System (DNS) - This option is incorrect because DNS is a protocol used to translate domain names into IP addresses. It is not a directory service.

Option C) NDS - This option is correct. NDS stands for Novell Directory Services, which is the directory service used in Netware. It provides a centralized database for managing and accessing network resources.

Option D) NWLink - This option is incorrect because NWLink is a protocol used for network communication in Netware. It is not a directory service.

Option E) DNS - This option is incorrect for the same reason as Option B. DNS is not a directory service.

The correct answer is C) NDS. This option is correct because NDS is the directory service used in Netware.

What diagnostic tool helps you find a malfunctioning network interface card?

  1. Multimeter

  2. Protocol Analyzer

  3. Signal Detector

  4. Null Network Unit

  5. Port Sniffer


Correct Option: B

AI Explanation

To answer this question, you need to understand the different diagnostic tools used to troubleshoot network issues. Let's go through each option to understand why it is correct or incorrect:

Option A) Multimeter - This option is incorrect because a multimeter is a tool used to measure voltage, current, and resistance in electrical circuits. It is not specifically designed to diagnose network interface card (NIC) issues.

Option B) Protocol Analyzer - This option is correct because a protocol analyzer is a diagnostic tool that captures and analyzes network traffic. It can help identify issues with a malfunctioning network interface card by examining the packets being sent and received by the card.

Option C) Signal Detector - This option is incorrect because a signal detector is used to detect and locate wireless signals, such as Wi-Fi or cellular signals. It is not specifically designed to diagnose network interface card issues.

Option D) Null Network Unit - This option is incorrect because a null network unit is a device used to simulate network connections and test network equipment. It is not specifically designed to diagnose network interface card issues.

Option E) Port Sniffer - This option is incorrect because a port sniffer, also known as a packet sniffer, is a tool used to capture and analyze network traffic. While it can help identify network issues, it is not specifically designed to diagnose network interface card issues.

The correct answer is B) Protocol Analyzer. This option is correct because a protocol analyzer is a diagnostic tool that captures and analyzes network traffic, helping to identify issues with a malfunctioning network interface card.

Which of the following support speeds of 1.5 Mbps?

  1. ISDN

  2. DSL

  3. USR

  4. ATM

  5. T1


Correct Option: E

AI Explanation

To answer this question, you need to understand the different types of network technologies and their corresponding speeds.

Let's go through each option to understand why it is correct or incorrect:

Option A) ISDN - Integrated Services Digital Network (ISDN) is a set of communication standards that enables digital transmission of voice, video, and data over traditional telephone lines. The maximum speed supported by ISDN is 128 Kbps, which is lower than 1.5 Mbps. Therefore, Option A is incorrect.

Option B) DSL - Digital Subscriber Line (DSL) is a technology that provides high-speed internet access over traditional telephone lines. While DSL can support speeds higher than 1.5 Mbps, it can also support lower speeds depending on the specific DSL variant and the distance from the DSL provider's central office. Therefore, Option B may or may not support speeds of 1.5 Mbps, so it is not the correct answer.

Option C) USR - USR (U.S. Robotics) is a brand that produces modems and networking equipment. However, the specific technology or product associated with "USR" is not provided in the question. Without knowing the specific context, it is not possible to determine whether USR supports speeds of 1.5 Mbps. Therefore, Option C cannot be determined as the correct answer.

Option D) ATM - Asynchronous Transfer Mode (ATM) is a networking technology that transmits data in fixed-size cells. ATM can support various speeds, including 1.5 Mbps. Therefore, Option D is a possible correct answer.

Option E) T1 - T1 is a dedicated digital communication line that supports a data rate of 1.544 Mbps. This speed is higher than 1.5 Mbps. Therefore, Option E is the correct answer.

The correct answer is Option E) T1. This option is correct because T1 supports speeds higher than 1.5 Mbps.
