Windows Hello is a biometric-based technology that enables Windows 10 users to authenticate secure access to their devices, apps, online services, and networks with just a look or a touch. If users have difficulty using the facial recognition feature, Windows Hello also supports a Personal Identification Number (PIN) as a secondary feature for logging in. The PIN is tied to the specific device on which it is set up, adding a layer of security even if the PIN is obtained by someone else.

Personal identification number: The PIN serves as an alternative to the facial recognition feature, allowing users to quickly and securely access their devices without relying solely on biometric authentication.

Username/password (B) is the traditional method of authentication but is not specifically a secondary feature of Windows Hello. One-time-use token (C) and cryptographic device (D) could be part of an MFA setup but are not directly related to Windows Hello's alternate authentication options.

A system image is a complete snapshot of everything on a device's storage at a given point in time, including the operating system, installed programs, system settings, and all user files. This method is the best way to back up the OS and data comprehensively because it allows for the restoration of a system to its exact state at the time the image was taken. This is particularly useful in disaster recovery scenarios where it's crucial to restore a system quickly and efficiently to minimize downtime.

To secure a SOHO wireless network, enabling WPA3 is the recommended option. WPA3 (Wi-Fi Protected Access 3) is the latest security certification program developed by the Wi-Fi Alliance to secure wireless computer networks. It provides cutting-edge security protocols and cryptographic methods to enhance and replace its predecessors, WPA2 and WPA, offering improved protection against brute-force attacks and ensuring better privacy on public networks​​.

A rollback plan describes the process of reverting a system to its previous state after a failed upgrade or change. This ensures system stability and functionality by restoring known good configurations and is a crucial part of change management to minimize disruptions in case of unsuccessful updates.
