In maintenance mode, which features of KPIs still function?

In maintenance mode, which features of KPIs still function?
A . KPI searches will execute but will be buffered until the maintenance window is over.
B . KPI searches still run during maintenance mode, but results go to itsi_maintenance_summary index.
C . New KPIs can be created, but existing KPIs are locked.
D . KPI calculations and threshold settings can be modified.

Answer: A

Explanation:

It’s a best practice to schedule maintenance windows with a 15- to 30-minute time buffer before and after you start and stop your maintenance work. This gives the system an opportunity to catch up with the maintenance state and reduces the chances of ITSI generating false positives during maintenance operations.
