Which of the following type of network models makes no differentiation between the devices that provide services and those that request services?

• Client-server

• Point-to-point

• Hub-and-spoke

• Peer-to-peer

A network administrator was told by the Chief Information Officer (CIO) to set up a new office with a network that has full redundancy. What topology would BEST meet the CIO's requirement?

• Hybrid

• Bus

• Mesh

• Star

Answer explanation

A mesh topology connects every endpoint to every other endpoint, creating a fully redundant network.

A network technician at a warehouse must implement a solution that will allow a company to track shipments as they enter and leave the facility. The warehouse workers must scan each package as it enters the warehouse using a sensor. Which of the following technologies should they utilize to meet these requirements?

• RFID

• Bluetooth

• NFC

Answer explanation

A network technician at a warehouse must implement a solution that will allow a company to track shipments as they enter and leave the facility.

Dion Worldwide has created a network architecture that relies on two main data centers, one in the United States and one in Japan. Each satellite office in the United States and Canada will connect back to the American data center, while each satellite office in Asia will connect back to the Japanese data center. Both the American and Japanese data centers are interconnected, as well. Therefore, if a client in the Philippines wants to send a file to the office in Miami, it will go first to the Japanese datacenter, then route across to the American datacenter, and then to the Miami satellite office. Which of the following network topologies best describes the Dion Worldwide network?

• Hub and spoke

• Star

• Bus

• Ring

Answer explanation

A hub and spoke topology is a network topology where a central device (the hub) is connected to multiple other devices (the spokes).

Hybrids network uses a combination of any _______ or more topologies.

• One

• Two

• None

• One and half

What topology uses token passing?

• Ring

• Square

• Hub

• Bus

Data on a star network passes through the hub, switch, or concentrator before continuing to its destination.

• True

• False

A hybrid topology is always produced when four different basic network topologies are connected.

• True

• False

A bus topology requires more cable length than a star topology.  

• True

• False
