The value of event_scheduler that enables checking status but not changing it at runtime is . . . . . . . .

Solution (By Examveda Team)

This question is about the event_scheduler in MySQL, which is a feature that allows you to schedule tasks (like running queries) at specific times or intervals.
The event_scheduler can be in two states: ON or OFF.
ON means the event scheduler is active and running. It will check the status of scheduled events and execute them when the time comes.
OFF means the event scheduler is inactive. It won't check for or run any scheduled events.
So, the question asks for the value that lets you check the status of the event scheduler without actually changing it.
The correct answer is Option B: OFF.
When event_scheduler is OFF, you can still view the status of the scheduler and the scheduled events. However, it won't actually execute any of them.
Think of it like this: Imagine you set a timer but didn't turn it on. You can still check the time set on the timer, but it won't start counting down until you turn it on.
