For a SOHO (Small Office/Home Office) router setup where the goal is to only allow specific computers on the network, MAC filtering is the appropriate solution:

Configure MAC filtering: This security measure involves creating a list of allowed device MAC (Media Access Control) addresses in the router's settings. Only devices with MAC addresses on this list will be able to connect to the network, effectively restricting access to authorized computers only.

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.

To safely upgrade the Microsoft Windows 10 OS, it is essential to backup critical data (C) and ensure that you have the necessary device drivers (D). Backing up critical data protects against potential data loss during the upgrade process. Having the correct device drivers ensures that the hardware components function properly with the new OS version, preventing issues like loss of functionality or compatibility problems​​.

Configuring a static IP address for a network printer in a SOHO (Small Office/Home Office) environment ensures that the printer maintains the same IP address over time. This consistency is crucial for networked devices like printers, as computers and other devices rely on this specific address to connect to the printer. If the printer's IP address were to change (as it might with DHCP), devices would no longer be able to communicate with it without reconfiguration.

Static IP: Assigning a static IP address to the printer ensures it always uses the same IP, making it reliably accessible to all computers in the house regardless of network changes or router reboots.

DNS settings (A) are generally not necessary to configure directly on most network printers unless you're dealing with advanced network configurations or using the printer for scanning to email functions. WWAN (C) stands for Wireless Wide Area Network, which is not typically relevant for a standard network printer setup in a home or small office. Metered connection (D) is a Windows feature that helps reduce data usage on a connection, it's not relevant to configuring a printer's network settings.
