Apple Updated Apple-Device-Support Exam Questions and Answers by teodor

Restoring an iPhone through Finder on a Mac performs a computer-based factory restore. Apple states that this process erases the device and installs the latest available iOS software, so option D is correct. This differs from Erase All Content and Settings performed directly on the iPhone, which removes user content and settings but is not the method identified here for reinstalling the latest operating-system software. Recovery Assistant is intended to resolve certain startup problems and is not the standard full factory-restore method described in the question. Erasing a device through Find My remotely removes content but does not represent the Finder-based operating-system reinstall process. In Finder, selecting the iPhone and choosing Restore iPhone causes the computer to erase the device and install the latest compatible iOS release.

When Private Wi-Fi Address is set to Rotating, the device periodically changes the private MAC address it presents to that Wi-Fi network. Apple documents that the Rotating setting changes to a different private address every two weeks, so option D is correct. The address is not the hardware MAC address defined by the device, an administrator, or a configuration profile. Instead, it is a randomized private address designed to reduce long-term tracking of the device across network activity. Apple devices generally use Fixed private addressing by default on networks using WPA2 or stronger security, while Rotating can be selected or used for networks with weak or no security. The rotation interval is specifically two weeks, not one week, which makes option C incorrect.

Starting with iOS 18, iPadOS 18, macOS Sequoia 15, watchOS 11, and visionOS 2, Apple provides Off, Fixed, and Rotating options for Private Wi-Fi Address. Apple documents that when a device joins a new network using WPA2 or stronger security, the Private Wi-Fi Address setting defaults to Fixed. A Fixed private address remains unique to that network but does not periodically rotate. By contrast, when joining a new network that uses weak security or no security, the device defaults to Rotating, which changes the private address every two weeks. MAC address filtering and IP address filtering are network access-control techniques and do not determine the default Private Wi-Fi Address mode. WEP is considered weak security and therefore does not trigger the Fixed default. Thus, WPA2 or WPA3 security is correct.

A recovery diagnostics file is generated while the Mac is running in macOS Recovery and can be requested when submitting diagnostic information, such as through Feedback Assistant. Apple’s macOS Recovery documentation instructs the user to connect an external storage device before generating the recovery diagnostics file. After the diagnostic process completes and the screen flashes, a dialog appears that allows the file to be saved to a location on that external storage device. Therefore, option C is correct. Locations such as `/Users/Shared` and `/var/root/Documents` are not the documented destinations for this Recovery workflow, and “Macintosh Data” is not the prescribed storage target. External storage provides a practical way to preserve and transfer diagnostic information when the normal macOS startup environment may not be available.
