Network Topologies and Protocols Quiz

Which network topology requires a dedicated point-to-point link between every device, resulting in the highest cable cost?

• Star

• Bus

• Ring

• Mesh

In which topology is network failure most likely to occur if the central connecting device fails?

• Bus

• Star

• Ring

• Mesh

Which topology uses a single backbone cable to which all nodes are directly connected?

• Star

• Mesh

• Ring

• Bus

Which of the following is a disadvantage of a Star topology?

• Easy to install and manage.

• Failure of one device does not affect the rest of the network.

• Easy to detect and isolate faults.

• Requires a large amount of cable compared to a Bus topology.

A network that combines the characteristics of two or more simple topologies (e.g., two Star networks connected by a Bus backbone) is classified as a:

• Simple Topology

• Point-to-Point link

• Complex Structure

• Hybrid Topology

Which guided transmission media offers the highest data transmission rate and is immune to electromagnetic interference?

• Coaxial Cable

• Unshielded Twisted Pair (UTP)

• Fiber Optic Cable

• Shielded Twisted Pair (STP)

Which cable type is most commonly used for modern 100 Mbps and 1 Gbps Ethernet networks within an office building?

• Coaxial

• Fiber Optic

• Unshielded Twisted Pair (UTP)

• Single-mode Fiber

A key characteristic of guided (wired) transmission media is:

• Communication is often limited to line-of-sight.

• It has a dedicated physical path for signal transmission.

• Signal propagation is subject to atmospheric interference.

• It is only suitable for local area networks.

Communication that uses radio waves and does not require a physical conductor between the sender and receiver is referred to as:

• Guided Media

• Baseband Signaling

• Broadband Signaling

• Unguided Media

Which category of cables suffers the most from attenuation (signal loss) over short distances?

• Fiber Optic Cable

• Coaxial Cable

• Twisted Pair Cable

• Single-mode Fiber
