A network architect is evaluating an existing industrial facility deployment that uses a hybrid physical star, logical bus network topology. Which of the following statements accurately describe the structural and operational characteristics of this hybrid network layout? (Select TWO.)
- A disruption or cable break between an individual workstation and its local switch node impacts only that specific host.Answer
- A failure along the central bus backbone segment disrupts inter-group communications across all attached star clusters.Answer
- CTraffic sent between distinct virtual local area networks (VLANs) across the bus automatically bypasses the need for Layer 3 inter-VLAN routing.
- DFraming units sent across the logical bus architecture are formatted as Layer 3 packets directly processed by end-station network interfaces.
Answer
The correct characteristics are that a single cable break between a workstation and its local hub/switch impacts only that workstation, and a failure on the main bus backbone severs communication between connected star clusters.
A hybrid physical star, logical bus topology uses star wired drops to local switch/hub clusters connected via a shared bus backbone. The physical star element ensures that a drop cable failure only disconnects the affected endpoint. Conversely, because the shared bus serves as the common interconnect for all clusters, a break in the central bus segment disables inter-segment transmission across the entire network.
