A) The local computer has been scanned for viruses.
B) The local computer has the latest operating system and updates.
C) The local computer connects to the network using VPN.
D) All files on the local computer have been backed up.
E) The network password meets all security criteria.

Answer 1

To transmit confidential data securely on a public wireless network, the most effective method is employing a VPN, as it encrypts the data in transit.

Step-by-step explanation:

Under the given options, a public wireless network can be used to transmit confidential data most securely when C) The local computer connects to the network using VPN. A VPN, or Virtual Private Network, encrypts data transmitted between the local computer and the internet, safeguarding the information against potential interceptors. Though having an updated operating system, a virus-free computer, backed up files, and a strong network password contribute to security, they do not directly protect data in transit over a public network in the same way a VPN does.
