A technician enables two-factor authentication (2FA) for a company's MDM enrollment portal after several unauthorized enrollment attempts. Which security benefit does this change MOST directly provide?
- AIt prevents devices from losing signal during Bluetooth pairing
- BIt requires a second verification factor beyond just a password to enroll a device
- CIt increases the mobile hotspot's maximum data throughput
- DIt automatically encrypts data synced between devices and the cloud
Show answer & explanationAnswer & explanation
Correct answer: B. It requires a second verification factor beyond just a password to enroll a device
Two-factor authentication requires users to provide a second verification method, such as a code sent to a registered device, in addition to a password, significantly reducing the risk of unauthorized MDM enrollment even if credentials are compromised.
Why the other options are wrong
- A. 2FA has no relationship to Bluetooth pairing signal stability.
- C. 2FA does not affect hotspot data throughput.
- D. 2FA is about authentication, not automatically encrypting synced data.
Two-Factor Authentication (2FA) for MDM
A security method requiring a second verification factor beyond a password to authenticate device enrollment in an MDM system.
- Reduces risk from stolen or guessed passwords
- Common second factors include SMS codes or authenticator apps
- Widely recommended for securing administrative and enrollment portals
Memory trick: 2FA = two locks on the enrollment door, not just one key.
