                                                                                            The correct choice is determined by the exact service boundary and operational requirement stated in the scenario.
                                                                                            Why the selected answer is Correct: The selected values fit this scenario because they apply the required Azure SQL configuration at the correct scope and sequence: You have an Azure SQL logical server.
                                                                                            Why the alternate choices are Wrong: The alternate selections apply to different administrative stages or different scopes. In a hotspot or drag-drop task, order and scope are part of the answer, so a technically valid Azure feature can still be wrong if it is placed in the wrong step.
