Question

Quizplus · Accepted Answer

A VPN encrypts data packets prior to transmission, which provides an additional layer of security. This means that even if a hacker intercepts the data, they will not be able to read it without the decryption key. Other types of networks may not encrypt data, leaving it vulnerable to interception and theft. Implementing usernames and passwords and challenging questions can provide additional security measures, but none of these options are as secure as encryption through a VPN. The option listed in D is not applicable as it describes a high level of physical security rather than network security.
