• Question 81:

  How do you reset the printing system from Printers and Scanners settings on a Mac?

  A. Control-click the printer, then choose Reset Printing System from the shortcut menu.

  B. Choose Printer Setup Utility > Reset printing system.

  C. Select all items, move them to the Trash, and refresh the screen.

  D. Select all the printers in the Printers list, then click Delete (-).

  Correct Answer: A

  Explanation: Resetting the printing system on a Mac can resolve problems such as print jobs stuck in the queue, connection issues, and incomplete driver setups. This process deletes all printers from your list of printers, deletes information about all completed print jobs, and deletes all printer presets. All printers and scanners must be set up again after completing the reset. To reset the printing system, you need to control-click the printer in the Printers list on the right, then choose Reset Printing System from the shortcut menu. You will be prompted to confirm that you want to reset your entire printing system.

  What should you do if you forgot your passcode and your iPhone is disabled?

  A. Put your iPhone in recovery mode, then connect it to your Mac or PC to restore it.

  B. Force shutdown your iPhone and wait 10 seconds, then turn it back on.

  C. Wait until the Forgot Passcode? message appears, then follow the instructions.

  D. Connect your iPhone to your Mac, then use Apple Configurator to revive the device.

  Correct Answer: A

  Explanation: If you forgot your passcode and your iPhone is disabled, you need to erase your iPhone and set it up again. The only way to do this is to put your iPhone in recovery mode and connect it to a computer with iTunes or Finder. This

  will erase all your data and settings, including the passcode, and install the latest version of iOS or iPadOS on your iPhone. You can then restore your data and settings from a backup, if you have one, or set up your iPhone as a new device.

  To put your iPhone in recovery mode, you need to follow these steps:

  Make sure that your iPhone is not connected to your computer, then turn it off completely.

  Press and hold the correct button for your iPhone model while connecting it to your computer. For iPhone 8 and later, use the side button. For iPhone 7 and 7 Plus, use the volume down button. For iPhone 6s and earlier, use the home button.

  Keep holding the button until you see the recovery mode screen on your iPhone, then release the button. The recovery mode screen shows a cable and a computer icon.

  On your computer, open iTunes or Finder and locate your iPhone. You should see a message that says there is a problem with your iPhone that requires it to be updated or restored.

  Choose Restore to erase your iPhone and install the latest software. This may take some time, so do not disconnect your iPhone until the process is complete. After your iPhone is restored, you can set it up again using the onscreen

  instructions. You can choose to restore from a backup or set up as a new device. References: = If you forgot your iPhone passcode; Apple Device Support Exam Prep Guide, page 8.

• Question 83:

  Select three responses.

  Which three conditions might require you to enter your passcode instead of using Face ID?

  A. The passcode has been entered incorrectly 5 times.

  B. The device was in sleep for more than 8 hours.

  C. The device has just been turned on or restarted.

  D. 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 hours.

  E. The device hasn't been unlocked for more than 48 hours.

  Correct Answer: CDE

  Explanation: Face ID is a biometric authentication method that allows you to securely unlock your iPhone or iPad, authenticate purchases, sign in to apps, and more, all with just a glance. However, there are situations where Face ID is not

  permitted and you need to enter your passcode instead. According to the Apple Device Support Reference Materials1, these situations include:

  The device has just been turned on or restarted.

  The user hasn't used their passcode or password to unlock their device for 156 hours (six and a half days), and the user hasn't used a biometric to unlock their device in 4 hours.

  The device hasn't been unlocked for more than 48 hours.

  Therefore, the correct answer is C, D, and E.

• Question 84:

  Select three responses.

  Which three scenarios cause Apple File System (APFS) volumes to generate encryption keys?

  A. During user creation

  B. At first user login on the Mac

  C. During the first macOS boot sequence

  D. During the first user's password creation

  E. After erase content and setting

  Correct Answer: ADE

  Explanation: 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.

• Question 85:

  You've forgotten your login password or it's locked from too many failed attempts to log in.

  What's the alternative method to unlock FileVault and reset your password?

  A. Create a new local recovery key.

  B. Use iCIoud Account Recovery.

  C. Call AppleCare to create a new account recovery key.

  Correct Answer: B

  Explanation: iCloud Account Recovery is an alternative method to unlock FileVault and reset your password if you've forgotten your login password or it's locked from too many failed attempts to log in. iCloud Account Recovery allows you to use your Apple ID and password to unlock your Mac and reset your user account password, if you stored your FileVault recovery key in iCloud when you turned on FileVault. To use iCloud Account Recovery, you need to restart your Mac and enter the Password Reset Assistant from the FileVault login screen or from Recovery Mode. Then, you need to select "I forgot my password" and sign in with your Apple ID and password. Follow the onscreen instructions to unlock your Mac and reset your password.

  How to put an iPhone in recovery mode?

  A. -Quickly press and release the Volume Up button.

  B. -Quickly press and release the Volume Down button.

  C. -Press and hold the Side (or Power) button until the Recovery Mode screen appears. Keep holding the button even when the Apple logo appears; release it only when the Recovery Mode screen is visible.

  Correct Answer: ABC

  Explanation: 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

• Question 87:

  ACME, Inc. wants all users to see mounted servers in the Finder by default.

  Which terminal command should you use to modify the Finder preferences to display mounted servers?

  A. defaults read com.apple.finder ShowMountedServersOnDesktop true

  B. defaults cat com.apple.finder ShowMountedServersOnDesktop true

  C. defaults write com.apple.finder ShowMountedServersOnDesktop true

  D. defaults append ShowMountedServersOnDesktop com.apple.finder true

  Correct Answer: C

  Explanation: The terminal command defaults write com.apple.finder ShowMountedServersOnDesktop true sets the Finder preference to show mounted servers on the desktop. This is equivalent to checking the box for "Connected Servers" in the Finder settings under the General tab. The other commands are either invalid or do not change the preference value. defaults read com.apple.finder ShowMountedServersOnDesktop true reads the current value of the preference, but does not modify it. defaults cat com.apple.finder ShowMountedServersOnDesktop true is not a valid command, as cat is not a valid subcommand for defaults. defaults append ShowMountedServersOnDesktop com.apple.finder true appends the value true to the preference key ShowMountedServersOnDesktop, which is not a valid operation, as the preference value should be a boolean, not a list.

• Question 88:

  Use this image to answer the question.

  

  Why is the screen sharing service disabled with the message "This service is currently unavailable"?

  A. TCP and UDP ports 5900 are currently blocked on this network.

  B. An internet connection is currently unavailable.

  C. Screen sharing is being controlled by the remote management service.

  D. Screen sharing is being controlled by the remote login service.

  Correct Answer: C

  Explanation: According to the image you sent, the screen sharing service is disabled because the remote management service is turned on. You can't have both screen sharing and remote management on at the same time. Remote management allows you to perform more advanced tasks on another Mac, such as installing and configuring apps, helping remote users, and creating detailed reports. Screen sharing allows you to view and control another Mac's screen. To enable screen sharing, you need to turn off remote management first. You can do this by going to System Settings > General > Sharing and deselecting Remote Management. Then you can check the box next to Screen Sharing to turn it on. Alternatively, you can use Apple Remote Desktop, a commercial app that combines the features of screen sharing and remote management, and works with both Intel-based and Apple silicon Macs.

• Question 89:

  How do you start up a Mac with Apple silicon in macOS Recovery?

  A. Turn on or restart the Mac, then immediately press and hold the Shift key as it starts up.

  B. Turn on or restart the Mac, then immediately press and hold Command-R until the Apple logo appears.

  C. With the Mac shut down, press and hold the power button until "Loading startup options" appears.

  Correct Answer: C

  Explanation: To start up a Mac with Apple silicon in macOS Recovery, you need to access the startup options screen first. This screen lets you choose different startup disks or modes, including macOS Recovery. To get to the startup options screen, you need to shut down your Mac completely, then press and hold the power button until you see "Loading startup options" on the screen. Then, you can click Options and click Continue to enter macOS Recovery1. The other options, pressing and holding the Shift key or Command-R, are not valid ways to start up a Mac with Apple silicon in macOS Recovery. These methods work on Intel-based Macs, but not on Macs with Apple silicon2. References: 1 Use macOS Recovery on a Mac with Apple silicon - Apple Support 2 Intro to macOS Recovery - Apple Support

• Question 90:

  Scenario

  Guillermo wants to annotate the Keynote presentation he created on his Mac on iPad.

  Select three responses.

  What does he need to do for Handoff to work on both devices?

  A. Turn on Wr-Fi.

  B. Turn on Bluetooth.

  C. Turn on iCIoud Drive.

  D. Sign in with the same Apple ID.

  E. Turn on AirPlay.

  Correct Answer: ABD

  Explanation: For Handoff to work on both devices, Guillermo needs to turn on Wi-Fi, Bluetooth, and sign in with the same Apple ID on his Mac and iPad. Handoff is a feature that allows users to start something on one device and then complete it on another. For example, Guillermo can start working on a Keynote presentation on his Mac and then continue annotating it on his iPad. To use Handoff, both devices must be on the same Wi- Fi network, have Bluetooth turned on, and be signed in with the same iCloud account. These are the prerequisites for Handoff to work. Turning on iCloud Drive or AirPlay is not necessary for Handoff. iCloud Drive is a cloud storage service that syncs files across devices, but it is not required for Handoff. AirPlay is a feature that streams audio and video from one device to another, but it is not related to Handoff.
