Day 1 Quiz - Introduction to Networking

Objective 1.2/Day 1 -

You have been asked to install a network that will give the network users the greatest amount of fault tolerance. Which of the following network topologies would you choose?

• Star/Hub-and-Spoke

• Ring

• Mesh

• Bus

Answer explanation

A mesh network uses a point-to-point connection to every device on the network. This creates multiple points for the data to be transmitted around the network and therefore creates a high degree of redundancy. The star/hub-and-spoke, ring, and bus topologies do not offer the greatest amount of fault tolerance.

Which of the following topologies allows for network expansion with the least amount of disruption for the current network users?

• Bus

• Ring

• LAN

• Star/hub-and-spoke

Answer explanation

On a star/hub-and-spoke network, each network device uses a separate cable to make a point-to-point connection to a centralized device, such as a hub or a switch. With such a configuration, a new device can be added to the network by attaching the new device to the hub or switch with its own cable. This process does not disrupt the users who are currently on the network. Bus and Ring are incorrect because the addition of new network devices on a ring or bus network can cause a disruption in the network and cause network services to be unavailable during the installation of a new device.

Match each description to the appropriate topology:

• Ring Topology

• Combines two or more different network topologies.

• Hybrid Topology

• All nodes are connected to a single cable or backbone.

• Bus Topology

• Consists of a central node (hub) connected to multiple peripheral nodes (spokes).

• Mesh Topology

• Each node is connected to exactly two other nodes, forming a circular arrangement.

• Star/Hub-and-Spoke Topology

• Every node is connected to every other node in the network.

What is a large network spread across an entire city called?

(a)

What is a dedicated, high-speed network that delivers shared pools of storage device to multiple servers called?

(a)

An organization requires a robust network topology that ensures high availability and fault tolerance. They want to ensure that even if one link fails, the network remains operational without interruption. Which network topology best meets these requirements?

• Star

• Bus

• Ring

• Mesh

Answer explanation

In a mesh topology, each node is connected to every other node, providing multiple pathways for data. This ensures high availability and fault tolerance, as the network can still function if one link fails.

A small office wants to set up a simple and cost-effective network where all devices can share resources equally without the need for a central server. Which network type would be most appropriate for this scenario?

• Peer-to-peer

• Client-server

• Metropolitan area network (MAN)

• Wide area network (WAN)

Answer explanation

In a peer-to-peer network, each device can act as both a client and a server, allowing for resource sharing without the need for a centralized server, making it simple and cost-effective for small networks.

A telecommunications company provides high-speed internet access to its customers using an infrastructure that allows multiple signals to travel simultaneously over the same medium. Which provider link technology is being used?

• Satellite

• Digital subscriber line (DSL)

• Cable

• Leased line

Answer explanation

Cable technology allows for high-speed internet access by using coaxial cables to carry multiple signals simultaneously, making it a popular choice for broadband internet services.
