Time Machine (Option A) is macOS's built-in backup application. It allows users to automatically back up their entire system, including apps, music, photos, emails, and system files. Time Machine provides an easy way to restore files from a previous state or recover from a system failure.
* FileVault (Option B) is used for encrypting data, not for backups.
* Keychain (Option C) is a password management tool.
* Mission Control (Option D) manages open windows and desktops but has no backup functionality.

B) Startup Folder1: The Startup folder is a special folder that contains shortcuts to programs or scripts that will run automatically when a user logs on. The technician can create a shortcut to the script and place it in the Startup folder for the conference room computer or for all users.
E) Task Scheduler23: The Task Scheduler is a tool that allows you to create tasks that run at specified times or events. The technician can create a task that runs the script at logon for the conference room computer or for all users.

The file type that the technician will MOST likely use when installing new software on a macOS computer is
.app. This is because .app is the file extension for applications on macOS1.

IoT (Internet of Things) devices are often considered a security concern due to their typically weak security protocols and the fact that many IoT manufacturers do not prioritize security when designing these devices.
These devices often lack the capability to be regularly patched or updated, which leaves them vulnerable to exploitation by attackers. The multitude of IoT devices, such as smart thermostats, cameras, and even light bulbs, when connected to a network, can serve as entry points for cyberattacks if not secured properly. In contrast, NICs (Network Interface Cards), PoE (Power over Ethernet), and LC (a type of fiber optic connector) do not inherently pose the same level of security risk as IoT devices because they are more established technologies and typically have better security practices in place.

Navigate to the Windows 10 Settings menu, select the Accounts submenu, select Sign in options, select Windows Hello Fingerprint, and have the user place a fingerprint on the fingerprint reader repeatedly until Windows indicates setup is complete. Windows Hello Fingerprint can be set up by navigating to the Windows
10 Settings menu, selecting the Accounts submenu, selecting Sign in options, and then selecting Windows Hello Fingerprint. The user will then be asked to place a fingerprint on the fingerprint reader repeatedly until Windows indicates that setup is complete. Windows Hello Fingerprint allows the user to log into the laptop using just their fingerprint, providing an additional layer of security.
