Least privilege is the principle that is used to ensure users have the appropriate level of access to perform their job functions. Least privilege means granting users only the minimum amount of access rights and permissions they need to perform their tasks, and nothing more. Least privilege reduces the risk of unauthorized access, data leakage, malware infection, or accidental damage by limiting what users can do on the system or network. Access control list, multifactor authentication, and mobile device management are not principles, but rather mechanisms or methods that can implement least privilege. Access control list is a list that specifies the users or groups that are allowed or denied access to a resource, such as a file, folder, or printer. Multifactor authentication is a method that requires users to provide two or more pieces of evidence to prove their identity, such as a password, a token, or a biometric factor. Mobile device management is a tool that allows managing and securing mobile devices, such as smartphones or tablets, that are used by employees to access corporate data or applications. References:

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.

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.

Apologizing to the customer and escalating the issue to a manager is the best course of action for the support center representative to take. This shows empathy and professionalism and allows the manager to handle the situation and provide the appropriate service or resolution for the customer.

For rendering video, the most critical component a customer should prioritize in a desktop is:
* GPU (Graphics Processing Unit): The GPU is specifically designed to handle complex graphics and video rendering tasks. A powerful GPU will significantly improve performance in video rendering applications.
* NIC (Network Interface Card): Important for network connectivity but irrelevant for video rendering.
* USB: Useful for peripherals but does not impact video rendering capabilities.
* HDMI: An important output interface for connecting monitors but not crucial for the rendering process itself.
