An image backup captures a complete snapshot of the entire system at a specific point in time, including the operating system, installed applications, user profiles, and system settings. This method is most suitable for backing up the components listed in the question because it ensures that every aspect of the workstation, from the core OS to individual user settings, is preserved and can be restored in its entirety. This is crucial for quickly recovering a system to a fully operational state after a failure or when migrating to new hardware. Other methods like differential, synthetic, and archive backups do not provide the comprehensive one-step restoration capability that an image backup offers for the complete system recovery.

Given that the smartphone's screen was recently repaired and now experiences issues with Wi-Fi connectivity, despite showing that it is connected to a network, the problem could be related to the internal antenna connections that might have been disturbed or disconnected during the repair process.

Internal Antenna Connections: Smartphones use internal antennas for Wi-Fi and cellular connections. If these antennas are not properly connected, the device may show as connected to a Wi-Fi network but fail to transmit data effectively, resulting in no internet access.

Checking static IP settings (B) would be relevant if the device were not obtaining an IP address at all, but the device does have an IP address. Airplane mode (C) would prevent the device from connecting to Wi-Fi networks entirely. Digitizer calibration (D) is related to the touchscreen functionality and would not affect Wi-Fi connectivity.
