A company requires that mobile devices used for work must have encrypted storage, screen locks, and remote wipe capability. Which solution enforces these policies?

Correct answer: Mobile Device Management (MDM)

Option C is correct because Mobile Device Management (MDM) is a purpose-built solution that allows organizations to enforce security policies on mobile devices, including mandatory storage encryption, screen lock requirements, and remote wipe capability, all from a centralized management console. Option A (VPN client) provides encrypted network tunnels for secure remote access but has no ability to enforce device-level security policies such as encryption or screen locks. Option B (Firewall rules) control network traffic at a perimeter or host level but cannot enforce security configurations on the mobile device itself. Option D (Antivirus software) protects against malware but does not provide policy enforcement for encryption, screen locks, or remote wipe functionality.
