FileVault is a feature that encrypts the entire APFS volume on a Mac using the AES-XTS data encryption algorithm. FileVault encryption keys are generated at different times depending on the scenario. According to the Apple Support documents12, FileVault encryption keys are generated in the following situations:
* During the first login by a user on the Mac: This happens when FileVault is turned on during the initial Setup Assistant process. The user's password and the hardware UID are used to protect the class key, which wraps the volume encryption key. The user's password is also used to generate a personal recovery key, which can be used to unlock the volume if the user forgets their password or their account is deleted.
* When a user turns on FileVault: This happens when FileVault is turned on later from the System Settings. The user's password and the hardware UID are used to protect the class key, which wraps the volume encryption key. The user's password is also used to generate a personal recovery key, which can be used to unlock the volume if the user forgets their password or their account is deleted. An anti-replay mechanism prevents the old key (based on hardware UID only) from being used to decrypt the volume.
* During user creation: This happens when a new user is added to the Mac after FileVault is turned on.
The new user's password and the hardware UID are used to protect the class key, which wraps the volume encryption key. The new user's password is also used to generate a personal recovery key, which can be used to unlock the volume if the user forgets their password or their account is deleted.
The other options are not correct because FileVault encryption keys are not generated in those situations.
When a user is deleted, their FileVault encryption key is removed from the Mac, but the volume encryption key remains the same. Setting the first user's password does not generate FileVault encryption keys unless FileVault is turned on during the Setup Assistant process or later from the System Settings.

The Q key is the universal shortcut to quit or exit a manual page in the Terminal window. The manual page, or man page, is a document that provides information about a command or utility in the Unix-like operating systems. The man command is used to display the man page for a given command or topic. The man command uses a pager program, such as less or more, to display the man page in the Terminal window. A pager program allows the user to scroll through the text file one page, line, or half-page at a time. To exit the pager program and return to the shell prompt, the user needs to press the Q key. This is the same for any other program that invokes the pager program, such as git log or git diff. The Q key stands for quit, and it is easy to remember for Mac users who are familiar with the Command + Q shortcut to quit an application.

To access files stored in iCloud Drive on your Windows PC, you need to download iCloud for Windows and set it up with your Apple ID1. This will allow you to view, add, or remove iCloud Drive files and folders directly on your Windows computer in File Explorer or Windows Explorer2. You can also choose a different location for your iCloud Drive files and folders on your PC2. Downloading iCloud Drive from the Windows App Store or copying the content of iCloud Drive from your Mac to an external drive are not valid options, as they will not sync your files across your devices or let you access them online345.
