A. StarExplanation
The correct answer is Star. In a star topology, cable segments are connected to a centralized component called a hub or a switch. All devices in the network are connected to this central hub, which acts as a communication point. This allows for easy management and troubleshooting as any issues with one device or cable segment do not affect the rest of the network.Rate this question:

- A.
Star
- B.
Bus
- C.
Linear
- D.
Mesh
Correct Answer
A. StarExplanation
The most common physical topology in Ethernet LANs is the star topology. In a star topology, all devices are connected to a central hub or switch, forming a star-like structure. This allows for easy scalability and troubleshooting, as each device can be individually connected or disconnected without affecting the rest of the network. Additionally, the central hub or switch acts as a central point of control, making it easier to manage and monitor the network.Rate this question:

208. What topology imitates an extended star topology and inherits properties of a bus topology?
- A.
Tree
- B.
Linear
- C.
Mesh
- D.
Ring
Correct Answer
A. TreeExplanation
A tree topology imitates an extended star topology because it has a central node (root) that connects to multiple nodes (branches), similar to how a star topology has a central hub connecting to multiple devices. Additionally, a tree topology inherits properties of a bus topology because the nodes in a tree are connected in a linear manner, similar to how devices are connected in a linear fashion in a bus topology.Rate this question:
