220-1102 macOS Features and Tools — Timed 10 Questions

Question 1

A security incident has occurred: a user's Mac running macOS Ventura was infected with malware that modified system files. The technician needs to boot the Mac into a mode that loads only essential Apple-signed kernel extensions and prevents third-party software from loading, in order to safely remove the malware. Which startup mode should they use?

Accepted Answer

Safe Mode (Shift key during startup).. Safe Mode (holding Shift during startup) loads only essential kernel extensions and disables all third-party startup items and login items. It also performs a directory check of the startup volume. This environment is ideal for troubleshooting and removing malware without interference. Single-user mode (Command+S) boots to a command-line interface but is deprecated on Apple Silicon Macs and does not inherently prevent malware from loading.

Answer

Single-user mode (Command + S).

Answer

Verbose mode (Command + V).

Answer

Target Disk Mode (T key).

Question 2

A user reports that their MacBook Pro running macOS Big Sur will not boot past the Apple logo. You suspect a corrupted system file. You need to boot into a special mode to run Disk Utility's First Aid on the startup volume. Which key combination should you hold during startup?

Accepted Answer

Hold Command (⌘) + R.. Holding Command (⌘) and R during startup boots the Mac into macOS Recovery, which provides access to Disk Utility, Terminal, and the ability to reinstall macOS. From there, you can run First Aid on the startup disk. Option (⌥) boots into Startup Manager, and Shift boots into Safe Mode.

Answer

Hold the Option (⌥) key.

Answer

Hold the Shift key.

Answer

Hold Command (⌘) + Option (⌥) + P + R.

Question 3

A user complains that their MacBook Air running macOS Monterey frequently runs out of memory and slows down when they have multiple browser tabs and apps open. They want to see which processes are consuming the most memory without installing third-party software. Which macOS tool should you instruct them to use?

Accepted Answer

Activity Monitor from the Utilities folder.. Activity Monitor is the built-in macOS utility that displays real-time system resource usage, including memory, CPU, energy, disk, and network. The Memory tab shows memory pressure and per-process memory consumption, helping identify memory hogs. Force Quit is only for terminating applications, not for monitoring.

Answer

Force Quit Applications window (Cmd+Option+Esc).

Answer

System Preferences > Memory.

Answer

Terminal with the 'top' command.

Question 4

A technician is troubleshooting a Mac that fails to connect to a Wi-Fi network. The network is visible, but entering the correct password results in an 'unable to join the network' error. The technician wants to delete the saved network configuration to start fresh. Which macOS tool or location should they use?

Accepted Answer

System Settings > Network > Wi-Fi > Details > Remove this network.. The Network pane in System Settings allows you to manage network interfaces, including Wi-Fi. By selecting the Wi-Fi interface and clicking 'Advanced' or 'Details', you can see a list of preferred networks and remove the problematic one. This clears the saved password and settings. Keychain Access stores passwords but not network configurations, and Terminal is not the standard method.

Answer

Keychain Access and delete the Wi-Fi password entry.

Answer

Terminal with the 'networksetup -setairportnetwork' command.

Answer

System Information > Network > Wi-Fi.

Question 5

A graphic designer needs to create a bootable macOS installer on an external SSD to deploy macOS Sonoma to multiple iMacs in the office. They have the 'Install macOS Sonoma.app' file. Which built-in macOS tool should they use to create the bootable drive?

Accepted Answer

Terminal with the 'createinstallmedia' command.. The 'createinstallmedia' command in Terminal is the official Apple tool for creating a bootable macOS installer from an application bundle. It writes the installer to the target volume and makes it bootable. Disk Utility can erase the drive but cannot create the installer media, and System Information does not have this capability.

Answer

Disk Utility to restore the .app file to the SSD.

Answer

System Information to verify the SSD is bootable.

Answer

Migration Assistant to copy the app to the SSD.

Question 6

A user has accidentally deleted several important files from their Documents folder on their Mac running macOS Ventura. They need to recover them immediately. Which built-in macOS tool should you guide them to use first?

Accepted Answer

The Trash folder in the Dock.. The Trash folder on macOS stores deleted files until it is emptied. If the user has not emptied the Trash, they can simply open the Trash icon in the Dock, locate the files, and drag them back to the Documents folder. Time Machine requires a backup to exist, and Terminal commands are unnecessary here.

Answer

Time Machine from the menu bar.

Answer

Terminal with the 'cd' and 'ls' commands.

Answer

System Settings > General > Storage.

Question 7

A small business owner wants to ensure that only authorized users can access their iMac. They need to set up separate accounts for three employees, each with a username and password, and restrict one employee from installing software. Which macOS feature should they use to create and manage these user accounts?

Accepted Answer

System Settings > Users & Groups.. System Settings (formerly System Preferences) contains the Users & Groups pane, which is the central location for creating, deleting, and managing user accounts on macOS. It allows setting account types (Administrator, Standard, Managed with Parental Controls) to control permissions and software installation. Terminal commands exist but are not the recommended primary tool for this task.

Answer

Terminal with the 'dscl' command.

Answer

System Information > Software > Installations.

Answer

Keychain Access to create user passwords.

Question 8

A user reports that their MacBook Air running macOS Monterey is running slowly and they suspect a startup item is consuming resources. They want to see which applications launch automatically at login and disable unnecessary ones. Which macOS tool should they use?

Accepted Answer

System Settings > General > Login Items.. System Settings > General > Login Items (or System Preferences > Users & Groups > Login Items on older macOS) lists all applications and services that start automatically when the user logs in. From there, the user can select an item and click the minus button to disable it. Activity Monitor shows running processes but does not manage startup items.

Answer

Activity Monitor and sort by CPU usage.

Answer

Terminal with the 'launchctl list' command.

Answer

Force Quit Applications window.

Question 9

A user on a Mac running macOS Big Sur needs to share a folder on their local network with a Windows colleague. The user wants the folder to appear as a network drive on the Windows machine without installing additional software. Which macOS feature should they enable and configure?

Accepted Answer

File Sharing in System Settings > Sharing, and ensure SMB is enabled.. File Sharing in System Settings uses SMB (Server Message Block) protocol, which is natively supported by Windows. By enabling File Sharing and adding the folder to the Shared Folders list, the Mac acts as an SMB server. The Windows user can then connect to it using the Mac's IP address or hostname. Screen Sharing is for remote desktop, not file sharing.

Answer

Screen Sharing in System Settings > Sharing.

Answer

Internet Sharing in System Settings > Sharing.

Answer

Remote Login in System Settings > Sharing.

Question 10

A user reports that their MacBook Pro running macOS Ventura suddenly lost all desktop icons and the menu bar is missing. They can still move the cursor and click on open applications. Which macOS feature or tool should you use to restore the desktop and menu bar?

Accepted Answer

Use Force Quit (Cmd+Option+Esc) and select Finder, then click Relaunch.. The scenario describes a Finder crash, which often causes the desktop, menu bar, and icons to disappear. Relaunching Finder via the Force Quit Applications window restores these elements without rebooting the entire system. This is a common troubleshooting step for macOS GUI issues.

Answer

Restart the MacBook by holding the power button.

Answer

Open Activity Monitor and force quit the WindowServer process.

Answer

Run the command 'sudo killall Dock' in Terminal.
