1. Which communication network has a leader at the center and poor horizontal communication?

Correct Answer: Correct answer is: (C) Wheel network.

Exam Relevance: Computer Science exams, Network Engineering exams, IT certifications

Difficulty: Moderate

Concept notes: In network topologies, the wheel network is characterized by a central node (leader) connected to all other nodes, with poor horizontal communication between the peripheral nodes.

Common Mistakes: A common misunderstanding is that the wheel network allows for efficient horizontal communication, but in reality, communication between peripheral nodes typically goes through the central node.

Explanations: The wheel network has a central node (leader) that is connected to all other nodes, but there are no direct connections between the peripheral nodes. This structure leads to poor horizontal communication because information must pass through the central node to reach other peripheral nodes.

Option Analysis:

Option A: The chain network has a linear structure where each node is connected to two adjacent nodes, except for the end nodes. This does not have a central leader or poor horizontal communication.
Option B: The vertical network is not a standard network topology. It may refer to a hierarchical structure, but it does not specifically describe a network with a central leader and poor horizontal communication.
Option C: The wheel network has a central node connected to all other nodes, with no direct connections between peripheral nodes, leading to poor horizontal communication.
Option D: The circle network (ring topology) has each node connected to two adjacent nodes, forming a closed loop. This allows for direct horizontal communication between nodes.

Mnemonic: Wheel spins around the leader.

2. P2P is a ..... application architecture.

Correct Answer: Correct answer is: (C) Distributed.

Exam Relevance: CCNA, CISSP, CompTIA Network+

Difficulty: Moderate

Concept notes: P2P (Peer-to-Peer) is a network topology where each node (or peer) can act as both a client and a server, allowing direct communication and resource sharing without the need for a central server.

Common Mistakes: A common misunderstanding is that P2P is similar to a client/server architecture, where there is a central server managing all communication. However, in P2P, each node can communicate directly with other nodes, making it a distributed system.

Explanations: In a P2P network, each node can both request and provide resources, eliminating the need for a central server. This makes the architecture distributed, as the workload and resources are shared among all participating nodes. This distributed nature allows for greater scalability and resilience compared to client/server architectures.

Option Analysis:

Option A: Client/server architecture involves a central server managing all communication, which is not the case in P2P networks.
Option B: A 1-tier architecture typically refers to a single layer of components, which does not apply to the distributed nature of P2P networks.
Option C: P2P networks are distributed, as each node can communicate directly with other nodes without a central server.
Option D: While P2P can share some characteristics with other architectures, it is specifically classified as distributed.

3. Network in your house is from type .....

Correct Answer: Correct answer is: (A) A LAN or Local Area Network.

Exam Relevance: CCNA, CompTIA Network+, CIW Network Specialist

Difficulty: Easy

Concept notes: A Local Area Network (LAN) is a computer network that interconnects computers within a limited area such as a residence, school, or office building.

Common Mistakes: A common mistake is confusing LAN with WAN, which covers a larger geographical area.

Explanations: A network in a house is typically a Local Area Network (LAN) because it connects devices within a small, localized area. This type of network is designed for a limited number of users and devices, making it suitable for home use.

Option Analysis:

Option A: Correct. A LAN is appropriate for a home network.
Option B: Incorrect. A WAN covers a much larger geographical area, such as cities or countries.

Mnemonic: LAN: Local Area Network

4. Which topology is used in this picture?

Correct Answer: Correct answer is: (C) Ring.

Exam Relevance: CCNA, Network+ Certification, CompTIA A+

Difficulty: Moderate

Concept notes: In a ring topology, each device is connected to exactly two other devices, forming a closed loop.

Common Mistakes: A common mistake is confusing the ring topology with the bus topology, where devices are connected to a single backbone.

Explanations: In a ring topology, data travels in one direction around the loop, passing through each device. Each device acts as a repeater, forwarding the data to the next device. This ensures that data is transmitted in a circular manner, making it a ring topology.

Option Analysis:

Option A: Bus topology has all devices connected to a single backbone, not forming a loop.
Option B: Star topology has all devices connected to a central hub, not forming a loop.
Option C: Ring topology has devices connected in a closed loop, which matches the description.
Option D: Tree topology is a hierarchical structure, not a closed loop.

Mnemonic: Ring like a circle, no start, no end.

5. Which 2 are Disadvantages of a Bus Topology?

Correct Answer: Correct answer is: (D) Only (A) & (B).

Exam Relevance: CCNA, Network+ Certification, CompTIA A+

Difficulty: Moderate

Concept notes: In a bus topology, all devices are connected to a single central cable. This topology is simple and cost-effective but has specific disadvantages.

Common Mistakes: A common mistake is confusing the central device failure issue with a bus topology. This issue is more relevant to star topologies.

Explanations: A bus topology has two significant disadvantages: more collisions with many devices on the network and the potential for the entire network to fail if the main cable is damaged. The central device failure issue is not applicable to bus topologies, as there is no central device in this configuration.

Option Analysis:

Option A: True. In a bus topology, all devices share the same cable, leading to more collisions when many devices are active simultaneously.
Option B: True. The main cable is critical in a bus topology. If it fails, the entire network is affected.
Option C: False. This issue pertains to star topologies, where a central device (hub or switch) is crucial. In a bus topology, there is no central device.
Option D: True. Only options (A) and (B) are correct disadvantages of a bus topology.

Mnemonic: Bus Breaks, Collisions Multiply

6. The layout of how computers are connected is

Correct Answer: Correct answer is: (C) Topology.

Exam Relevance: CCNA, CompTIA Network+, CIW Network Specialist

Difficulty: Easy

Concept notes: Network topology refers to the layout or arrangement of how computers and other devices are connected in a network.

Common Mistakes: A common misunderstanding is confusing network topology with the type of network (e.g., LAN, WAN), which refers to the geographical scope and connectivity of the network rather than the layout.

Explanations: Topology describes the physical and logical layout of a network, including the arrangement of devices and the connections between them. This is distinct from the type of network or other network characteristics.

Option Analysis:

Option A: Network refers to the entire system of interconnected devices, not the layout of connections.
Option B: Type refers to the classification of the network (e.g., LAN, WAN), not the layout of connections.
Option C: Topology correctly describes the layout of how computers are connected in a network.
Option D: None of the above is incorrect because topology is the correct term for the layout of network connections.

7. A ..... network consists of a single central cable, to which all computers and other devices connect.

Correct Answer: Correct answer is: (D) Bus.

Exam Relevance: CCNA, CompTIA Network+, CIW Network Specialist

Difficulty: Easy

Concept notes: In a bus network topology, all devices are connected to a single central cable, known as the bus.

Common Mistakes: A common mistake is confusing the bus topology with the ring or star topologies, which have different connection patterns.

Explanations: A bus network consists of a single central cable, to which all computers and other devices connect. This central cable acts as a shared communication medium, allowing devices to send and receive data. This topology is simple and cost-effective but can suffer from performance issues and reliability concerns as the number of devices increases.

Option Analysis:

Option A: A ring network topology connects devices in a closed loop, where each device is connected to two others, forming a ring. This is not the correct answer as it does not describe a single central cable.
Option B: A star network topology connects all devices to a central hub or switch. This is not the correct answer as it does not describe a single central cable.
Option C: A token ring network topology is a type of ring network where a special frame called a token is passed around the ring to control access to the network. This is not the correct answer as it does not describe a single central cable.
Option D: A bus network topology consists of a single central cable to which all devices are connected. This is the correct answer as it matches the description given in the question.

Mnemonic: Bus = Big Unified System
