  2. 802.2

  3. 802.3

  4. 802.4

  5. 802.5

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 It is used in some legacy systems but has largely been replaced by Ethernet.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

networking

  1. 50 Ohm Terminator

  2. Crimp Connector

  3. Null Connector

  4. Loop Connection

  5. No Termination Needed

Show answer
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.

You install a network adapter on IRQ 3, which of the following might it conflict with?

networking

  1. COM1

  2. COM2

  3. Keyboard

  4. Hard Drive Controller

  5. Display Card

Show answer
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?

networking

  1. Active Directory

  2. Domain Name System

  3. NDS

  4. NWLink

  5. DNS

Show answer
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.
