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

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.

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.
