Microsoft 365 Certified Endpoint Administrator (MD-102) Practice Test

Which authentication method ensures that all enrolled devices use a secure method for device enrollment?

1. Usernames and passwords

2. Biometric authentication

3. PIN authentication

4. Certificate-based authentication

The correct answer is: Certificate-based authentication

Certificate-based authentication is the most secure method for device enrollment because it relies on the use of digital certificates, which are much harder to forge or compromise than traditional credentials. When a device is enrolled using certificate-based authentication, a unique certificate is issued to the device that confirms its identity and establishes a trusted relationship between the device and the network. This ensures that only authorized devices can access the resources within the organization, thereby maintaining the integrity and security of the network. On the other hand, usernames and passwords can be susceptible to various attacks such as phishing or brute force, making them less secure for device enrollment. Similarly, biometric authentication, while more secure than passwords, can still be vulnerable to spoofing attacks and may not be universally supported across all devices. PIN authentication adds a layer of security over usernames and passwords, but it still falls short of the robust protections offered by certificate-based methods. Overall, utilizing certificate-based authentication for device enrollment not only enhances security but also streamlines the process, ensuring that only trusted and enrolled devices are allowed access to the network.
