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

What is considered the most secure authentication method for device enrollment in Microsoft Endpoint Manager?

1. Certificate-based authentication

2. User-based authentication

3. Password-based authentication

4. Token-based authentication

The correct answer is: Certificate-based authentication

Certificate-based authentication is considered the most secure authentication method for device enrollment in Microsoft Endpoint Manager due to several key factors. First, certificate-based authentication employs digital certificates that are inherently more difficult to duplicate or forge compared to passwords or tokens, which might be intercepted or stolen. Each device can have a unique certificate, ensuring that only authorized devices can enroll and connect to the network. This eliminates the risk associated with password-based methods, where users may choose weak passwords or reuse them across multiple accounts. Furthermore, certificates are tied to a specific device and user identity, creating a strong link that enhances security. This linkage makes it significantly more challenging for unauthorized users or devices to gain access. Additionally, certificates can be revoked if a device is compromised or if the user no longer needs access, providing a straightforward way to manage security while maintaining control over the enrollment process. In contrast, user-based authentication still relies on individual user credentials, which can be less secure due to human errors, such as password reuse or poor management of credentials. Password-based authentication, while commonly used, is often vulnerable to a variety of attacks, such as phishing and brute force attacks. Token-based authentication can offer a balance of security but is typically subject to expiration and may require additional management, which
