Which of the following is the best way to limit the loss of confidential data...

Configuring remote wipe allows the device owner or administrator to erase all the data on the device remotely, in case it is lost or stolen. This prevents unauthorized access to confidential data and reduces the risk of data breaches. Installing a VPN, implementing location tracking, and enabling backups are useful features, but they do not directly limit the loss of data if the device is compromised. References: CompTIA A+ Certification Exam Core 2 Objectives, Domain 2.0: Security, Objective 2.5: Given a scenario, use methods to secure mobile devices.
