1. What would happen if a node in a star-wired Ethernet network failed?

Explanation

If a node in a star-wired Ethernet network fails, only that specific node would be unable to transmit or receive data. The rest of the network would continue to function normally. This is because in a star-wired network, each node is connected directly to a central hub or switch, and the failure of one node does not affect the connectivity of the other nodes.

2. In a network using the star topology, five workstations and a hub would be connected via how many physical cables?

Explanation

In a network using the star topology, each workstation is directly connected to the hub using a separate cable. Since there are five workstations, they would be connected to the hub via five physical cables. Therefore, the correct answer is five.

Submit
3. What type of terminator is used on a star-wired network?

Explanation

Star-wired networks do not require terminators. In a star-wired network, each device is connected directly to a central hub or switch, creating a point-to-point connection. This eliminates the need for terminators, which are typically used in bus or daisy-chain networks to absorb signals and prevent reflections. In a star-wired network, the central hub or switch handles the signal distribution, making terminators unnecessary.

Submit
4. What is the function of a hub in a star-wired network?

Explanation

A hub in a star-wired network functions by repeating signals to all nodes on the segment. This means that when a signal is received by the hub, it is then broadcasted to all connected devices, ensuring that each node receives the signal. This allows for easy communication between devices on the network.

Submit
5. What would happen to a star network if one of its workgroup hubs failed?

Explanation

If one of the workgroup hubs in a star network fails, all nodes connected to that hub would be unable to communicate with nodes on other segments as well as nodes on their own segment. This is because the failed hub acts as a central point for communication between different segments, and without it, the nodes cannot transmit data to other segments or within their own segment.

Submit
6. Which of the following is an advantage to using star topology networks over using bus or ring topology networks?

Explanation

Star topology networks are more scalable because they allow for easy addition or removal of devices without affecting the rest of the network. In a star topology, each device is connected directly to a central hub, which makes it simple to expand the network by connecting new devices to the hub. This flexibility allows for easy growth and adaptability as the network requirements change over time. In contrast, bus or ring topology networks may require more complex reconfiguration or disruption of the entire network when adding or removing devices.

Submit
7. In which of the following networks would it make the most sense to implement a star topology? (Choose all that apply)

Explanation

A star topology is most suitable for a home network that connects two computers because it is simple to set up and provides a centralized control point, making it easy to manage and troubleshoot. Similarly, a LAN that connects a dozen computers in an insurance company would benefit from a star topology as it allows for efficient communication and easy expansion. In both cases, the star topology provides a reliable and scalable network solution.
