App preference files are files that store the rules or parameters that tell your apps how they should work. They usually have the .plist extension and are associated with a specific app’s bundle identifier. App preference files are typically stored in two locations on a Mac: the user library and the system library. The user library is located at -/Library/Preferences and contains the preference files for the current user. The system library is located at /Library/Preferences and contains the preference files for all users. These locations are different from the root library, which is located at /System/Library/Preferences and contains the preference files for the operating system and its components. You can access these locations by using the Finder, the Terminal, or the defaults command line utility. You can also edit, delete, or reset the preference files using various methods, but you should be careful not to damage or corrupt them, as they may affect the functionality of your apps. References:

 The Q key is the universal shortcut to quit or exit a manual page in the Terminal window. The manual page, or man page, is a document that provides information about a command or utility in the Unix-like operating systems. The man command is used to display the man page for a given command or topic. The man command uses a pager program, such as less or more, to display the man page in the Terminal window. A pager program allows the user to scroll through the text file one page, line, or half-page at a time. To exit the pager program and return to the shell prompt, the user needs to press the Q key. This is the same for any other program that invokes the pager program, such as git log or git diff. The Q key stands for quit, and it is easy to remember for Mac users who are familiar with the Command + Q shortcut to quit an application. References: = How to escape out of the MAN screen or page in UNIX?, How to Exit the MAN Command and Quit Man Pages Properly, How to Quit the MAN Command and Exit Man Pages Properly, How to jump to the end of a ‘man’ page

 Sysdiagnose log files are located on iPhone in Settings > Privacy & Security > Analytics & Improvements > Analytics Data. Sysdiagnose is a tool that collects information from the iPhone and saves it in a log file. You can use sysdiagnose to troubleshoot general iOS issues or report them to AppleCare. To generate a sysdiagnose log file, you need to press and hold both volume buttons and the side or top button for 1 to 1.5 seconds, then release them. You will see a screenshot and a message that says “Diagnostics are in flight”. Sysdiagnose can take up to 10 minutes to finish. After that, you can find the log file in the Analytics Data section of the Settings app. The log file name will start with “sysdiagnose_” and include the date and time of the generation, the device type, and the iOS version. For example, “sysdiagnose_2024.01.06_17-14-34+0500_iPhone_OS_iPhone_19A344.tar.gz”. References: Using Sysdiagnose to Troubleshoot iOS or iPadOS — Apple Device Support Tutorials | Apple Training, How to extract sysdiagnose logs for forensic purposes on iOS | Andrea Fortuna

On your Mac, choose Apple menu > System Settings, click Privacy & Security in the sidebar, then click FileVault on the right. (You may need to scroll down.) Click Turn On. You might be asked to enter your password.

Sidecar is a feature that lets you use your iPad as a display that extends or mirrors your Mac desktop. You can use Sidecar to work with different apps on the different screens, use the same app on both screens, or mirror the screens so that they show the same content. You can also use your Apple Pencil to draw, edit, or mark up documents on your iPad while seeing the updates live on your Mac. Sidecar requires macOS 10.15 or later and iPadOS 13 or later on supported models. You can use Sidecar wirelessly or with a USB cable. To use Sidecar, you need to select your iPad from the Display menu in Control Center or the menu bar on your Mac, or from the AirPlay menu on macOS Catalina. You can also use the sidebar and the Touch Bar on your iPad to access common Mac controls and app-specific commands. The other options are not the correct answer, as they have different functions or are not available on macOS and iPadOS.

Universal Control is a feature that lets you use a single keyboard, mouse, or trackpad to control your Mac and iPad, with the iPad showing its own Home Screen and apps rather than the desktop and apps of your Mac. You can also drag and drop content between your devices. Universal Control requires macOS Monterey or later and iPadOS 15 or later on supported models.

Screen Sharing is a feature that lets you remotely view or control another Mac or share your Mac screen with others over the internet. You can use Screen Sharing to help someone with a problem, collaborate on a project, or access your files and apps. Screen Sharing requires macOS 10.14 or later on both Macs, and an Apple ID or a local network connection.

Stage Manager is not a feature on macOS or iPadOS. It is a feature on watchOS 8 or later that lets you control the camera and microphone on your iPhone from your Apple Watch. You can use Stage Manager to take photos, record videos, zoom in and out, adjust the exposure, mute the sound, and switch between the front and back cameras on your iPhone. References:

APFS is a file system that supports encryption at the volume level. Each volume has its own encryption key, called the Volume Encryption Key (VEK), which is stored in the APFS container metadata and protected by another key, called the Key Encryption Key (KEK). The KEK is derived from the user’s password and wrapped by a secure token, which is a feature that ensures only authorized users can access the encrypted data. According to the Apple Device Support Reference Materials12, the following scenarios cause APFS volumes to generate encryption keys:

During user creation. When a new user is created on an APFS volume, a secure token is generated for that user and a KEK is derived from the user’s password. The KEK is used to encrypt the VEK and store it in the metadata.

During the first user’s password creation. When the first user on an APFS volume sets their password, a secure token is granted to that user and a KEK is derived from the password. The KEK is used to encrypt the VEK and store it in the metadata.

After erase content and setting. When a user erases all content and settings on an APFS volume, the VEK and the KEK are deleted and new ones are generated. The new VEK is encrypted with the new KEK and stored in the metadata.

Network settings is the macOS resource that displays the status of network interfaces in a dynamic list. You can access Network settings from System Preferences > Network, or by clicking the network icon in the menu bar and choosing Open Network Preferences. Network settings shows you the available network interfaces, such as Wi-Fi, Ethernet, Bluetooth, etc., and their connection status, IP address, DNS server, and other information. You can also use Network settings to configure, enable, disable, or troubleshoot your network connections. References: = Apple Device Support Exam Prep Guide, page 11; Apple - Support - Manuals, macOS User Guide, Network preferences.

 The Apple Pencil (2nd gen) is a stylus that allows you to draw, write, and interact with your iPad in a natural and precise way. The Apple Pencil (2nd gen) has a flat edge that attaches magnetically to the side of your iPad for pairing, charging, and storage. It also supports double-tap gestures to switch tools or modes in compatible apps. The Apple Pencil (2nd gen) is compatible with any iPad that has a USB-C port and a flat edge for magnetic attachment. According to the Apple Device Support Reference Materials1, these iPad models are:

iPad Pro 12.9-inch (3rd gen and later)

iPad Pro 11-inch (all generations)

iPad mini (6th gen)

iPad Air (4th gen and later)

Therefore, the correct answer is A, B, D, and E.

 Face ID is a biometric authentication feature that allows users to unlock their device with a facial scan. Face ID attempts to match the user’s face with the stored data every time the device is woken up. However, there are situations where Face ID is not permitted or fails to recognize the user. In those cases, the user must enter their passcode or password to unlock the device. One of those situations is when there are five unsuccessful attempts to match a face. After five failed scans, Face ID is disabled and the user is prompted to enter their passcode or password. This is a security measure to prevent unauthorized access to the device by someone who does not look like the user. References: Face ID, Touch ID, passcodes, and passwords - Apple Support, What Is Face ID? - How-To Geek
