Pass Using Apple-Device-Support Exam Dumps

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

Two-factor authentication is an extra layer of security for your Apple ID, designed to make sure that you’re the only one who can access your account—even if someone else knows your password1. When you sign in with your Apple ID for the first time on a new device or on the web, you need both your password and the six-digit verification code that’s automatically displayed on your trusted devices1. A trusted device is a device that you’ve already signed in to with your Apple ID and that can receive verification codes1. You can also add or remove trusted devices and phone numbers from your Apple ID account page1. Two features of two-factor authentication for a personal Apple ID are:

• It ensures that only the account’s owner can access the account. This is because you need to verify your identity with both your password and a verification code that is sent to a device or phone number that only you have access to1. This prevents unauthorized access to your account even if your password is compromised or stolen1.
• It can be accessed on trusted devices. This means that you can sign in to your Apple ID account on devices that you’ve already verified with two-factor authentication without needing to enter a verification code again1. This makes it easier and faster to access your account on devices that you use frequently and trust1.

 According to the Apple Device Support Reference Materials, one of the basic troubleshooting steps for peripheral devices is to unplug and reconnect the device1. This can force the Mac to reinitialize the connection and reload any device-specific drivers. Other options, such as connecting the peripheral to a USB hub, unplugging other devices on the same bus, or connecting the peripheral to another Mac, may not necessarily reinitialize the connection or reload the drivers, and may introduce other issues or complications. References: 1: Apple Device Support Reference Materials, Section 2.3.1, "Basic Troubleshooting Steps".

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
