On a Mac, Activity Monitor is the primary tool for monitoring system resource usage, including the amount of memory (RAM) consumed by individual apps. Found in Applications > Utilities, it provides a real-time view under the " Memory " tab, showing memory usage in megabytes or gigabytes per app, along with system-wide statistics.

Option A (Console) logs system events and errors but doesn’t display memory usage.

Option B (Apple Diagnostics) tests hardware integrity, not runtime memory stats.

Option C (System Information) offers hardware and software details (e.g., total RAM) but not per-app memory usage.

Option D (Activity Monitor) is correct and widely used for this purpose. This functionality remains consistent in macOS up to 2025. Refer to Apple’s " Use Activity Monitor on your Mac " (support.apple.com/HT201464) for details.

For Apple silicon Macs, hold the power button until startup options appear, then press Command-D to start Apple Diagnostics.

Option A: Shift is for Safe Mode.

Option C: Option-D isn’t valid here.

Option D: D alone works on Intel, not always silicon.

Option-clicking the Wi-Fi menu bar icon shows detailed connection info (e.g., IP, channel).

Option B: System Settings doesn’t respond this way.

Option C: Control-click offers basic options.

Option D: Control-click in Settings doesn’t detail this.

In Settings > Wi-Fi , tapping a network’s info (i) shows the Auto-Join toggle. Disabling it prevents the iPhone from automatically connecting to that network, even if previously joined.

Option A: Ask to Join Networks prompts for new networks, not known ones.

Option B: Auto-Link isn’t an iOS setting.

Option C: Preferred Networks isn’t a toggleable option.

Managed apps, deployed via an MDM solution, are tied to the device’s enrollment. Unenrolling from MDM (e.g., removing the profile in Settings > General > VPN & Device Management ) deletes these apps, as they’re organization-controlled.

Option A: Resetting network settings affects connectivity, not apps.

Option C: Releasing from Apple Business Manager requires admin action, not user action.

Option D: Signing out of a personal account doesn’t remove managed apps.

Configuration profiles (e.g., MDM settings) are reviewed in Settings > General > VPN & Device Management on iOS. This section lists installed profiles, allowing users to view or remove them (if permitted).

Option A: Privacy & Security handles app permissions, not profiles.

Option B: No “Profiles > Remote Management” exists.

Option D: Profiles aren’t under Privacy & Security.

Organizations create Managed Apple Accounts in Apple Business Manager/School Manager for controlled, work-specific use.

Option A: Personal is user-created.

Option B: Not a term.

Option D: Not a distinct type.

A system crash triggering a restart sends analytics to Apple (if enabled in System Settings > Privacy & Security > Analytics & Improvements ) to improve macOS.

Option A: Diagnostics doesn’t send data automatically.

Option B: App failures don’t trigger this.

Option C: Privacy blocks don’t report.

Safari profile syncing requires:

C: Safari enabled in iCloud ( Settings > [user name] > iCloud ).

E: Same Apple Account across devices for iCloud continuity.

Option A: Two-factor authentication enhances security but isn’t a sync requirement.

Option B: Contact Key Verification is for iMessage, not Safari.

On Apple silicon Macs (e.g., recent MacBook Pros), hold the power button until “Loading startup options” appears, then select “Options” > “Continue” to enter macOS Recovery.

Option A: Command-Option-R is for Internet Recovery, not standard.

Option C: Power-Shift-Control-Option isn’t valid.

Option D: Command-R works on Intel Macs, not always silicon.
