Someone hacked into an employees computer and erased all of their data. All data for the past three weeks was lost as that was when the employee last performed a backup. Which type of network is the company more than likely using?

A. centralized

B. client server

C. GUI

D. peer to peer

The correct answer is letter "D": peer to peer.

Explanation:

Peer to Peer (P2P) networks are constituted by computers connected through the internet. Anybody with a computer internet access can connect to another computer within the same network and share files with no need for a central server granting access. The biggest disadvantage of this type of network is that as there is no central server, file sharing and back up are not controlled.

B. client server

Explanation:

Someone hacked into an employees computer and erased all of their data. The employee had last performed a backup three weeks back. This means that there is a backup server in the company. In other words, the network architecture is of the form client-server where data from the employee computers is backed up to a centralized repository from where content could be restored. Hence option B represents the most likely choice.
