Questions Related to networking

  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 It is used in some legacy systems but has largely been replaced by Ethernet.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

How do you terminate a 10BaseT cable?

  1. 50 Ohm Terminator

  2. Crimp Connector

  3. Null Connector

  4. Loop Connection

  5. No Termination Needed


Correct Option: E

AI Explanation

To answer this question, you need to understand the termination requirements for a 10BaseT cable.

A 10BaseT cable is an Ethernet cable that operates at a speed of 10 megabits per second (Mbps) and uses the twisted pair cable technology. In this type of cable, termination is not required.

Termination is typically used in certain types of cables, such as coaxial cables, to prevent signal reflections at the end of the cable. However, in the case of 10BaseT cables, termination is not needed because the twisted pair cable technology used in these cables already provides sufficient signal integrity.

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

A) 50 Ohm Terminator - This option is incorrect because a 50 Ohm terminator is typically used for terminating coaxial cables, not twisted pair cables like 10BaseT.

B) Crimp Connector - This option is incorrect because a crimp connector is used to attach a connector to the end of a cable, but it does not provide termination.

C) Null Connector - This option is incorrect because a null connector is used to connect two devices without actually transmitting any data. It is not used for terminating a cable.

D) Loop Connection - This option is incorrect because a loop connection refers to connecting the two ends of a cable together to form a loop, but it is not used for termination.

E) No Termination Needed - This option is correct because termination is not required for a 10BaseT cable. The twisted pair cable technology used in 10BaseT already provides sufficient signal integrity.

The correct answer is E) No Termination Needed. This option is correct because termination is not needed for a 10BaseT cable.

  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

  1. Active Directory

  2. Domain Name System

  3. NDS

  4. NWLink

  5. DNS


Correct Option: C
  1. Multimeter

  2. Protocol Analyzer

  3. Signal Detector

  4. Null Network Unit

  5. Port Sniffer


Correct Option: B

Which type of backup copies files created or changed since the last full backup?

  1. Application

  2. Physical

  3. Network

  4. Transfer

  5. Session


Correct Option: C

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.

Which cable supports a speed of 100 Mbps?

  1. Category 1

  2. Category 2

  3. Category 3

  4. Category 4

  5. Category 5


Correct Option: E

AI Explanation

To answer this question, we need to understand the different categories of network cables.

Category 1 (Cat 1) cables are the oldest and do not support data transmission. They were primarily used for telephone communications.

Category 2 (Cat 2) cables were an improvement over Cat 1 cables, but they still do not support high-speed data transmission. They were also used for telephone communications.

Category 3 (Cat 3) cables can support data transmission at up to 10 Mbps. They were commonly used for Ethernet networks in the past.

Category 4 (Cat 4) cables can support data transmission at up to 16 Mbps. They were also used for Ethernet networks but are less common today.

Category 5 (Cat 5) cables can support data transmission at up to 100 Mbps. They became widely used for Ethernet networks and are still commonly used today.

Based on this information, we can see that the correct answer is E) Category 5. This cable can support a speed of 100 Mbps.
