Difficulty: EasyNetwork Topologies and Types

An IT technician is deploying a local network for a small office using a physical star topology where all workstation nodes connect to a central Ethernet switch. Which of the following statements correctly describe the fundamental characteristics of this topology? (Select TWO.)

  1. A failure of the central switch breaks network communication for all connected devices on that segment.Answer
  2. Adding or disconnecting an individual host cable does not disrupt traffic between the other active hosts.Answer
  3. C
    Every host on the network connects directly to every other host using dedicated point-to-point physical links.
  4. D
    All hosts share a single continuous coaxial cable trunk terminated at both physical ends.

Answer

A physical star topology is characterized by a central device acting as a single point of failure for the segment, and individual point-to-point cable runs that allow adding or removing nodes without disrupting remaining network traffic.
A star topology connects each host directly to a central node (such as a switch). Consequently, failure of that central node halts all traffic on the segment, while individual cable connections can be connected or disconnected without disrupting other hosts.

Step-by-Step Solution

1
Identify the core structural component of a star topology.
All host devices connect independently to a central device such as a network switch.
This establishes point-to-point connections between endpoints and the central node.
2
Evaluate the impact of central device failure versus individual link failure.
Failure of the central node impacts the whole segment, but single link disconnects only affect the corresponding endpoint.
Each endpoint uses an isolated physical link to the central device.
