Answer choices
Why each option matters
Answer the question above first, then reveal the full breakdown to understand why each option is right or wrong.
Correct answer & explanation
✓
MDM
Mobile Device Management (MDM) allows organizations to enforce policies, manage apps, and secure data on mobile devices.
Answer analysis
Option-by-option breakdown
For each option: why learners choose it and why it is or isn't the right answer here.
- ✗
DNS
Why it's wrong here
DNS resolves names to IP addresses and provides no device enrolment, policy enforcement or remote wipe capability. It is tempting because DNS filtering can block malicious domains on phones, but that is content filtering, not fleet management.
- ✗
NAC
Why it's wrong here
NAC controls network admission for devices connecting to the corporate network; it does not enrol, configure or wipe smartphones. It would be correct for enforcing endpoint compliance on wired or wireless LAN access, not for fleet device management.
- ✗
VPN
Why it's wrong here
A VPN encrypts traffic between a device and a network but cannot enforce passcodes, deploy apps or remotely wipe a lost phone. It would be the right choice for securing data in transit over untrusted networks, not for managing the device fleet itself.
- ✓
MDM
Why this is correct
MDM provides centralised enrolment, policy enforcement, remote wipe and configuration for employee smartphones, directly meeting the requirement to manage and secure the device fleet. It targets device-level control rather than application wrapping or identity alone.
