Apple-Device-Support Apple Device Support Exam (SUP-2024) Questions and Answers

This is the correct answer because Activity Monitor is a built-in macOS utility that allows you to see how much CPU, memory, disk, and network resources are being used by each app and process on your Mac. You can use Activity Monitor to identify and quit apps that are consuming a large percentage of your CPU or memory, or that are not responding. This can help you improve the performance and responsiveness of your Mac. To launch Activity Monitor, you can use Spotlight (Command+Spacebar) and search for it, or find it under Applications > Utilities. You can sort the apps and processes by clicking on the column headers, such as “% CPU” or “Memory”. You can also use the search field to filter the list by name. To quit an app or process, select it and click on the “X” button at the top of the window. You can also use the View menu to see more information about the app or process, such as its open files and ports, its memory usage, or its energy impact. References: How to See Which Program Is Using All Your CPU on Mac, If your Mac runs slowly - Apple Support, How to Fix Crashing Apps on a Mac - How-To Geek

Emergency SOS is a feature on your iPhone that lets you quickly and easily call for help and alert your emergency contacts. To access Emergency SOS on your iPhone, you need to press and hold the side button and one of the volume buttons until the Emergency SOS slider appears on the screen. You can then drag the slider to call emergency services, or continue holding the buttons to start a countdown and an alert sound. If you release the buttons after the countdown, your iPhone automatically calls emergency services. Emergency SOS works differently depending on your iPhone model and region. For example, in India, you need to press the side button three times rapidly to call emergency services. You can also customize the settings for Emergency SOS, such as adding emergency contacts, enabling auto call, and turning off the countdown sound. References: Use Emergency SOS on your iPhone - Apple Support, How to trigger Emergency SOS on your iPhone (and shut it off)

According to the Apple Device Support Reference Materials, the steps to put an iPhone in recovery mode are:

• Plug your iPhone in to your computer using your USB to Lightning cable1.
• On a Mac with macOS Catalina or later, open the Finder. On a Mac with macOS Mojave or earlier, or on a PC, open iTunes1.
• Quickly press and release the Volume Up button, then quickly press and release the Volume Down button, and then press and hold the Side (or Power) button until the recovery mode screen pops up12. It won’t happen instantly, so hang on for at least 15 seconds or so before you try it again2.
• Locate your device on your computer and choose the option to Update or Restore1.

These steps apply to all iPhones manufactured since 2017, including iPhone 8 or later, iPhone SE (2nd and 3rd generations), and iPhone 12 or later2. For older models, such as iPhone 7 or earlier, the steps may vary slightly1. References: 1: If you can’t update or restore your iPhone or iPod touch - Apple Support 2: How to put your iPhone or iPad into recovery mode | iMore

These are the correct answers because these are the two authentication methods that users can use to lock a note in the Notes app on their iPad devices. Users can choose to use their device passcode or a custom password for each Notes account. If they use their device passcode, they can also use Face ID or Touch ID to access their locked notes. If they use a custom password, they have to enter it on all devices where they are signed in with the same Apple ID. Users can also switch between the two methods in the Settings app. To lock or unlock a note, users have to tap the three-dotted More button and choose the Lock option, or tap the Lock icon in the top toolbar. References: Lock your notes on iPhone - Apple Support (CA), How to lock individual Apple Notes using your iPhone’s passcode - Inverse

According to the Apple Device Support Reference Materials, you need your passcode to enable Face ID when:

• You have just turned on or restarted your device by force restart or automatically after an OTA software update1.
• Your device has failed to match a face for 5 times1.
• You haven’t unlocked your device for more than 48 hours1.

The other two options, C and D, are not correct because they are based on incorrect or incomplete information. The correct condition for option C is that the passcode hasn’t been used to unlock the device in the last six and a half days and Face ID hasn’t unlocked the device in the last 4 hours1. The correct condition for option D is that your device has received a remote lock command1. References: 1: Use Face ID on your iPhone or iPad Pro - Apple Support, Section "Require a passcode".

If you forget your iPhone passcode, you can use a Mac to erase your iPhone and remove the passcode. This will delete all your data and settings, but you can restore them from a backup if you have one. To erase your iPhone using a Mac, you need to put your iPhone in recovery mode and connect it to the Mac with a cable. Then, you need to open Finder and locate your iPhone. You will see an option to Restore or Update your iPhone. Choose Restore and wait for the process to complete. After your iPhone is erased, you can set it up again and restore your data from a backup or iCloud. References: If you forgot your iPhone passcode - Apple Support, Erase your iPhone - Apple Support

 Activation Lock is a feature that prevents unauthorized use of an Apple device after it has been erased. It is enabled automatically when a user turns on Find My on their device. However, for devices that are owned or managed by an organization, there are two types of Activation Lock available: device-linked and user-linked. Device-linked Activation Lock requires Apple School Manager, Apple Business Manager, or Apple Business Essentials and an MDM solution. It allows the MDM solution to control turning Activation Lock on and off through server-side interactions, without depending on the user’s Apple ID or Find My settings. The MDM solution creates and sends a bypass code to Apple servers when it needs to lock or unlock the device. User-linked Activation Lock requires the user to have a personal Apple ID (not a Managed Apple ID) and to turn on Find My on their device. This method allows the user to lock an organization-linked device to their personal Apple ID if the MDM solution has allowed Activation Lock. The MDM solution should request and store a bypass code from the device before allowing the user to turn on Activation Lock. This bypass code can be used to turn off Activation Lock remotely with MDM, or directly on the device, if the user is unable to authenticate with their Apple ID. References:

 A warning icon might appear in the Security Recommendation window for a password in Passwords settings if the password meets any of the following criteria:

• The password is reused on another website. This means that the same password is used for more than one saved password across different domains. This can make the accounts vulnerable to credential-stuffing attacks, where attackers try the same credentials on other services to compromise additional accounts1.
• The password appeared in a data leak. This means that the password has been compromised by a data breach and exposed online. This can allow attackers to access the accounts that use the leaked password or try to guess other passwords based on the leaked one1.
• It’s a commonly used password or it’s easily guessed. This means that the password is weak and may be easily cracked by an attacker. This can happen if the password uses words found in a dictionary, common character substitutions, patterns found on a keyboard, or repeated sequences. These patterns are often used to create passwords that satisfy minimum password requirements for services, but are also commonly used by attackers attempting to obtain a password using brute force1. References: 1: Password security recommendations - Apple Support

 You can enter your iPhone passcode wrong up to ten times before your account is disabled. After six failed attempts, your iPhone will be disabled for one minute. After seven attempts, it will be disabled for five minutes. After eight attempts, it will be disabled for 15 minutes. After nine attempts, it will be disabled for 60 minutes. After ten attempts, it will be disabled until you connect it to a computer and restore it using iTunes or Finder12. References: = If you forgot your iPhone passcode - Apple Support; What to do when your iPhone is disabled | Tom’s Guide.

Activity Monitor is an app that shows information about the processes running on your Mac, including how much CPU, memory, disk, network, and energy they use.

Activity Monitor is a useful tool for troubleshooting performance issues on your Mac and optimizing its efficiency. References: Use Activity Monitor on your Mac, How to see all the running programs on your Mac, How to See Which Program Is Using All Your CPU on Mac, How to track and kill processes on your Mac

Disk Utility on Mac supports several file system formats for formatting, partitioning, and erasing disks. According to the Apple Device Support Reference Materials1, these formats are:

• Apple File System (APFS): The file system used by macOS 10.13 or later, which features strong encryption, space sharing, snapshots, fast directory sizing, and improved file system fundamentals. APFS is optimized for the Flash/SSD storage used in recent Mac computers, but it can also be used with older systems with traditional hard disk drives (HDD) and external, direct-attached storage. APFS supports four variants: APFS, APFS (Encrypted), APFS (Case-sensitive), and APFS (Case-sensitive, Encrypted).
• Mac OS Extended: The file system used by macOS 10.12 or earlier, which is also known as HFS Plus or HFS+. Mac OS Extended supports journaling, which helps protect the integrity of the file system in case of power outages or hardware failures. Mac OS Extended also supports four variants: Mac OS Extended (Journaled), Mac OS Extended (Journaled, Encrypted), Mac OS Extended (Case-sensitive, Journaled), and Mac OS Extended (Case-sensitive, Journaled, Encrypted).
• ExFAT: A file system that is compatible with both Mac and Windows computers, and can be used for transferring files between them. ExFAT supports larger file sizes than FAT32, up to 16 EB, and larger volumes, up to 128 PB. ExFAT does not support journaling, encryption, or case sensitivity.
• MS-DOS (FAT): A file system that is compatible with both Mac and Windows computers, and can be used for transferring files between them. MS-DOS (FAT) supports two variants: FAT16 and FAT32. FAT16 is limited to 2 GB volumes and 4 GB files, while FAT32 can support up to 2 TB volumes and 4 GB files. MS-DOS (FAT) does not support journaling, encryption, or case sensitivity.

Therefore, the correct answer is A, C, D, and F.

To create a bootable macOS installer that includes macOS Recovery on an external storage device, you need to use the Mac OS Extended format, also known as HFS+. This is because the createinstallmedia command, which is used to create the bootable installer, requires the volume to be formatted as Mac OS Extended. APFS (Apple File System) is not supported by createinstallmedia, and neither are the encrypted versions of APFS or Mac OS Extended. Therefore, the correct answer is D. Mac OS Extended. References: Create a bootable installer for macOS, How to create a bootable USB macOS installer, How to format the startup drive for a Mac

 FileVault is a feature that encrypts the data on your Mac’s startup disk, making it more secure. To unlock your Mac, you need to enter your account password or a recovery key. A recovery key is a 28-character code that is generated when you turn on FileVault. You can choose to store it in iCloud or write it down and keep it in a safe place. An iCloud account and password can also be used to reset your FileVault password, if you enabled this option when you turned on FileVault. The other options, authenticator app, using a trusted device, and SMS verification code, are not valid ways to reset a FileVault password on a Mac. References: 1 Use FileVault to encrypt the startup disk on your Mac - Apple Support 2 Reset a macOS User Password - Kandji 3 How to unlock your Mac with its Recovery Key and FileVault active - Macworld

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.

To start up in safe mode on a Mac with Apple silicon, you need to follow these steps1:

• Shut down your Mac, then press and hold the power button for three seconds.
• When the startup options window appears, select your startup disk.
• Click the Continue in Safe Mode button.
• Log in to your Mac.

Safe mode can help you identify whether issues you’re experiencing are caused by software that loads as your Mac starts up. It prevents your Mac from loading certain items, performs a First Aid check on your startup disk, and deletes some caches1. You can verify that your Mac started up in safe mode by using the System Information app1.

The other options are incorrect because they either do not show the Continue in Safe Mode button, or they do not use the correct key combination or timing to enter safe mode.

If a revive is unsuccessful, you can use Apple Configurator to restore the Mac. A restore updates the firmware, updates recoveryOS to the latest version, and erases and installs the latest version of macOS on your internal storage. When this process is complete, any data on any internal volumes is unrecoverable. You must restore the firmware and erase the internal flash storage if reviving the firmware is unsuccessful or if you can’t start the Mac from the startup volume or the recoveryOS. References: Revive or restore a Mac with Apple silicon using Apple Configurator - Apple Support

Quick Start is a feature that allows you to set up your new iOS device automatically using your current iOS device.

 The next step in troubleshooting the app’s issue is to upgrade to the latest version of the app. This can help resolve any compatibility issues, bugs, or performance problems that the app may have with your version of macOS1. You can check for updates to your software by opening the App Store and looking at the Updates section for apps that you got from the App Store, or by visiting the app developer’s website for apps that you got from another source1. Upgrading to the latest version of the app may also provide new features or enhancements that can improve your user experience2.

Creating a new file, removing the preference file, reinstalling or upgrading macOS, or troubleshooting application preferences are not the best options for this scenario, as they may not address the root cause of the app’s issue, or they may be too drastic or time-consuming. Creating a new file may not help if the app quits regardless of the file type or content3. Removing the preference file may delete your custom settings or preferences for the app, and it may not fix the issue if the app has a problem with its code or resources4. Reinstalling or upgrading macOS may erase your data or settings, and it may not be necessary if the issue is specific to the app and not the operating system5. Troubleshooting application preferences may be useful if the app has a problem with its configuration or options, but it may not work if the app has a problem with its compatibility or functionality.
