Comprehensive and Detailed In-Depth Explanation:
Passwords provide the highest level of security because they cannot be bypassed using biometric spoofing techniques.

* B. Swipe - Very weak security.
* D. Fingerprint - More secure than face/swipe but can still be faked.

The best ways to limit the bank's risk are to enable multifactor authentication for each support account and enforce account lockouts after five bad password attempts. Multifactor authentication adds an extra layer of security to the login process, making it more difficult for attackers to gain access to systems. Account lockouts after five bad password attempts can help to prevent brute force attacks by locking out accounts after a certain number of failed login attempts.

The best filesystem format to ensure read and write compatibility of USB flash drives across several generations of Microsoft operating systems is FAT32. FAT32 stands for File Allocation Table 32-bit and is a filesystem format that organizes and manages files and folders on storage devices using 32-bit clusters.
FAT32 is compatible with most Microsoft operating systems since Windows 95 OSR2, as well as other operating systems such as Linux and Mac OS X. FAT32 can support storage devices up to 2TB in size and files up to 4GB in size. APFS stands for Apple File System and is a filesystem format that organizes and manages files and folders on storage devices using encryption, snapshots and cloning features. APFS is compatible with Mac OS X 10.13 High Sierra and later versions but not with Microsoft operating systems natively. Ext4 stands for Fourth Extended File System and is a filesystem format that organizes and manages files and folders on storage devices using journaling, extents and delayed allocation features. Ext4 is compatible with Linux operating systems but not with Microsoft operating systems natively.

Open-source software is software that has its source code available for anyone to inspect, modify, and distribute. Open-source software is usually free of charge and does not require a license to use. Some examples of open-source antivirus software are ClamAV, Comodo, and Immunet12. The other license types are either not free or not suitable for a SOHO PC. Corporate and enterprise licenses are designed for large- scale organizations and networks, and they usually require a subscription fee. Personal licenses are for individual users and may have limited features or support.

Resetting the network adapter is the best way to apply the changes made to the hosts file on a few PCs. The hosts file is a text file that maps hostnames to IP addresses and can be used to block certain domains by redirecting them to invalid or local addresses. Resetting the network adapter will clear the DNS cache and force the PC to use the new entries in the hosts file.
