Network Topologies

What is the most common wired topology used in networks?

• Ring

• Bus

• Star

• Mesh

Answer explanation

The most common wired topology used in networks is the Star topology. This topology is characterized by a central hub that connects all devices in the network. Each device is connected to the hub, allowing for easy communication between devices. The Star topology offers several advantages, including simplicity of installation, scalability, and ease of troubleshooting. It is widely used in both small and large networks due to its reliability and flexibility.

What is the major benefit of the star topology?

• High redundancy level

• Easy installation and troubleshooting

• Handles failure well

• No single point of failure

Answer explanation

The major benefit of the star topology is that it eliminates the single point of failure. This means that even if one device fails, the rest of the network can still function. The star topology also offers easy installation and troubleshooting. It provides high redundancy level and handles failure well. However, the correct choice is 'No single point of failure' as it best describes the major benefit of the star topology. The star topology ensures that the failure of any single device does not bring down the entire network, making it a reliable option for network connectivity.

Which topology requires terminators at both ends of the cable?

• Ring

• Bus

• Star

• Mesh

Answer explanation

A bus topology requires terminators at both ends of the cable. In this topology, all devices are connected to a single cable, forming a linear structure. The terminators prevent signal reflections and ensure smooth communication. The correct choice is 'Bus'.

Which topology is rarely used today?

• Ring

• Bus

• Star

• Mesh

Answer explanation

The question asks about a topology that is rarely used today. Among the given options, the correct choice is 'Ring.' The Ring topology forms a closed loop where each device is connected to the previous and next device. This topology is not commonly used due to its limitation of transmitting data in one direction only. Therefore, the Ring topology is the correct answer.

What is the advantage of a mesh topology?

• Easy installation and troubleshooting

• Handles failure well

• High redundancy level

• No single point of failure

Answer explanation

A mesh topology has the advantage of high redundancy level, which means that there are multiple paths for data to travel in the network. This ensures that if one path fails, the data can still be transmitted through alternative routes. This leads to improved reliability and fault tolerance. Unlike other topologies, such as a star topology, a mesh network does not have a single point of failure. It offers easy troubleshooting and installation, and handles failure well. However, the high redundancy level is the standout advantage of a mesh topology.

Which topology is mainly used on wide area networks like the internet?

• Ring

• Bus

• Star

• Mesh

Answer explanation

The question asked is about the topology mainly used on wide area networks like the internet. The correct choice is 'Mesh'. Mesh topology is commonly used in wide area networks as it provides high reliability and fault tolerance. In this topology, every device is connected to every other device, forming a network of interconnected nodes. This allows for efficient data transmission and easy fault detection. Mesh topology is ideal for networks that require high performance and reliability, such as the internet.

What is the purpose of a wireless access point in an infrastructure wireless topology?

• To connect wired devices to the network

• To create a peer-to-peer network

• To connect wireless devices to the network

• To act as a bridge between wired and wireless networks

Answer explanation

The purpose of a wireless access point in an infrastructure wireless topology is to act as a bridge between wired and wireless networks. It allows wireless devices to connect to the network and enables communication between wired and wireless devices. This setup ensures seamless connectivity and enables access to network resources for both wired and wireless devices. The wireless access point provides a centralized connection point for wireless devices, improving network coverage and facilitating efficient data transmission. It enhances network flexibility and enables convenient access to the network without the need for physical wired connections.

What is the advantage of a wireless mesh topology?

• Easy installation and troubleshooting

• Handles failure well

• High redundancy level

• No single point of failure

Answer explanation

The advantage of a wireless mesh topology is its high redundancy level. This means that even if one node fails or loses connection, the network can still operate as other nodes can take over the communication. This ensures reliable and uninterrupted connectivity. The wireless mesh topology also offers easy installation and troubleshooting, handles failure well, and eliminates the risk of a single point of failure. However, its key advantage lies in the high redundancy level, which enhances network resilience and reliability.

What is the purpose of multiple wireless access points in a wireless mesh topology?

• To create a peer-to-peer network

• To connect wired devices to the network

• To connect wireless devices to the network

• To provide seamless internet connection throughout a building

Answer explanation

The purpose of having multiple wireless access points in a wireless mesh topology is to provide seamless internet connection throughout a building. It allows for the creation of a network that ensures uninterrupted coverage and connectivity. By strategically placing access points, wireless devices can stay connected without any interruptions or dead zones. This setup is particularly useful in larger spaces or buildings where a single access point may not be sufficient to cover the entire area.

A router can

• Forward data packets

• Absorb signals

• Repeat signals

• absorb data packets

Answer explanation

A router is a networking device that forwards data packets between computer networks. It is designed to connect multiple networks together and determine the best path for data transmission. In this case, the router can forward data packets, which means it can send data from one network to another. This functionality allows for efficient communication and connectivity between different networks. The other options mentioned, such as absorbing signals or repeating signals, are not the primary functions of a router. Therefore, the correct answer is that a router can forward data packets.
