   A legacy manufacturing floor uses a single coaxial cable running through the facility, with each machine tapping into it. The network has been experiencing frequent outages, and the IT team suspects that a loose connection at one machine is bringing down the entire network. Which physical topology is in use, and what is the primary drawback?

   • AMesh topology; too many redundant links are required
   • BStar topology; the central hub is a single point of failure
   • CBus topology; a single break or fault can disable the entire segment
   • DRing topology; data must pass through each device in sequence

   A small office network is set up so that each computer is connected to exactly two other computers, forming a closed loop. Data travels in one direction, passing through each computer until it reaches the destination. The office manager wants to add a new computer without disrupting the network. What is the main challenge with this topology?

   • AThe network requires terminators at both ends of the cable
   • BAdding a device requires breaking the loop, which temporarily disconnects all devices
   • CEach device needs a direct link to every other device
   • DThe central switch becomes a bottleneck

   Which statement correctly contrasts logical and physical topologies?

   • APhysical topology determines how data is transmitted, while logical topology determines cable layout.
   • BLogical topology describes data flow, while physical topology describes the physical arrangement of devices and cables.
   • CLogical topology is always identical to physical topology.
   • DPhysical topology is only relevant for wireless networks.

   What is a significant drawback of a single-ring topology?

   • AIt is difficult to add new devices.
   • BIt requires a large amount of cabling.
   • CIt cannot support high-speed data transmission.
   • DA failure in any device or link can disrupt the entire ring.
