What is the action required to enable 'Do Not Disturb' mode on an iPhone?

Enabling 'Do Not Disturb' mode on an iPhone is accomplished by selecting the 'Do Not Disturb' option in the control center. This feature allows users to silence incoming calls, alerts, and notifications while the screen is locked, providing a way for individuals to focus or avoid distractions.

When accessed through the control center, users can easily turn this feature on or off, as well as adjust settings such as allowing calls from specific contacts or silencing notifications while the device is locked. This makes the process straightforward and accessible, especially when you want to quickly enable or disable it without going into the settings menu.

Other options do not achieve the purpose of activating 'Do Not Disturb'. The silent switch is meant to mute sounds but does not prevent notifications from lighting up the screen. Turning off Wi-Fi or enabling Airplane mode alters connectivity settings and would not specifically address the need to silence notifications or calls while still allowing the user to use the phone for other functions.
