Network Topologies and Layer 2 Switches

In an office, Isabella is setting up a network where all computers are connected to a single main cable. She notices that the network requires terminators at both ends of the cable and that all devices share the same communication channel. What are the characteristics of the network topology Isabella is using?

• Uses unshielded twisted pair (UTP) cables and has multiple collision domains.

• Uses coaxial cable, requires terminators, and has a single collision domain.

• Connects devices in a circular fashion, passing data in one direction.

• Employs a central device to which all other devices are connected.

Lily is setting up two small office networks. In one office, she uses a hub to connect all the computers, and in the other, she uses a bus topology. How do these two networks compare in terms of collision and broadcast domains?

• Both have one collision domain and one broadcast domain.

• A hub creates multiple collision domains, while a bus has one.

• A hub creates multiple broadcast domains, while a bus has one.

• A hub has one collision domain and multiple broadcast domains, while a bus has one of each.

Sophia is setting up a small office network and wants to ensure that each device connected to the network has its own dedicated collision domain. Which device should she use that learns Layer 2 addresses and creates a dedicated collision domain for each connected port?

• It operates at Layer 1 and functions as a multi-port repeater.

• It learns Layer 2 addresses and creates a dedicated collision domain for each connected port.

• It forwards all incoming traffic to all connected devices, regardless of destination.

• It is primarily used for routing traffic between different networks.

Priya is setting up a small office network and is deciding between using a Layer 2 switch or a hub to connect the computers. What is the primary advantage of using a Layer 2 switch over a hub in her network?

• Switches are less expensive and easier to configure than hubs.

• Switches reduce the number of broadcast domains, while hubs do not.

• Switches create multiple collision domains, improving network performance by reducing collisions.

• Switches use coaxial cables, which are more reliable than UTP cables used by hubs.

Sophie is setting up a Token Ring network in her office. She notices that the cables are arranged in one way, but the way data travels is different. In a Token Ring network, how is the physical topology typically configured compared to its logical operation?

• Physically a ring, logically a bus.

• Physically a star, logically a ring.

• Physically a bus, logically a star.

• Physically a ring, logically a star.

Oscar works for a company that has offices in different countries. The company needs a network that can connect all these offices, even though they are far apart and not in the same city. What type of network should Oscar consider for this purpose?

• It connects devices within a single building or campus.

• It uses only wireless connections for data transmission.

• It connects geographically dispersed sites that are not physically close.

• It is exclusively used for connecting local servers to workstations.

Mia is setting up a network for her company, where the main office serves as a central site and all branch offices connect directly to it, but not to each other. Which WAN topology is Mia using?

• Full Mesh

• Partial Mesh

• Hub and Spoke

• Point-to-Point

In a company with offices in multiple cities, the IT manager, Isla, is considering different network topologies for their Wide Area Network (WAN). Which topology is characterized by each office having a direct connection to every other office?

• All sites connect to a single central hub.

• Each site has a direct connection to every other site.

• Only critical sites have redundant connections.

• Connections are established only when data needs to be transmitted.
