Difficulty: EasyNetwork Topologies and Types

A network administrator is planning a local network deployment using a physical star topology for a newly opened branch office. Which of the following represent key operational characteristics of a physical star topology? (Select TWO.)

  1. All host endpoints connect directly to a central networking device such as a switch.Answer
  2. A failure in an individual host cable run does not cause an outage for other connected devices.Answer
  3. C
    Every individual node must maintain a dedicated physical cable link to every other node on the network.
  4. D
    All devices share a single continuous coaxial backbone terminated at both endpoints.

Answer

The correct characteristics are that all host endpoints connect directly to a central networking device such as a switch, and a failure in an individual host cable run does not cause an outage for other connected devices.
In a physical star topology, all network endpoints are connected directly to a central connecting device (such as a Layer 2 switch). This architecture provides host fault isolation, ensuring that a severed cable connected to one host does not affect the connectivity of other hosts on the switch.

Step-by-Step Solution

1
Analyze the physical structure of a star topology.
Identify that devices connect individually to a central distribution point (e.g., a switch).
Centralization is the defining physical property of star architecture.
2
Evaluate fault isolation behavior for star topologies.
Confirm that an open circuit or cable failure on a single endpoint cable only impacts that single endpoint.
Independent point-to-point cable runs prevent single endpoint failures from propagating across the network.
