Explanation

In the Juniper Mist AI for Wired dashboard, administrators can select one or more switch ports (as shown in the exhibit, e.g., port ge-0/0/25 on an EX4100-48MP). Once configuration changes are made -- such as VLAN assignment, port profiles, PoE settings, or administrative state -- the Save button must be clicked to confirm and apply those changes to the device. "When making configuration changes in the Mist switch interface, the Save button must be used to confirm the modifications. Clicking Save applies the selected port settings to the switch through Mist Cloud." Option A is incorrect: saving does not create a backup. Backups and snapshots are handled through Mist's configuration archive, not via the Save button. Option B is incorrect: Save does not reset configuration; instead, it commits changes. Option C is incorrect: there is no preview function tied to Save. Option D is correct: the Save button is explicitly for applying configuration changes to the selected switch or port(s).
