A database specialist is creating a new parameter group for an Amazon RDS database instance. What property do parameters of type “static” have?

Answer options:

A.They cannot be modified.
B.They can be modified.
C.Database instances will require a manual reboot before the parameter is applied.
D.Database instances will not require a manual reboot before the parameter is applied. The parameter is applied immediately.

Answer: C
Static parameters require a manual reboot of the Amazon RDS instance before they are applied. Dynamic parameters do not require a manual reboot and are applied immediately.
Therefore, Option C is CORRECT, and all other options are incorrect.
