A database specialist has a fleet of Amazon RDS DB instances that use the default DB parameter group.The database specialist needs to associate a custom parameter group with some of the DB instances.
After the database specialist makes this change, when will the instances be assigned to this new parameter group?
Instantaneously after the change is made to the parameter group
In the next scheduled maintenance window of the DB instances
After the DB instances are manually rebooted
Within 24 hours after the change is made to the parameter group
Explanations:
Changes to the DB parameter group are not applied instantaneously. They take effect after a reboot of the DB instance.
The change will not wait until the next scheduled maintenance window. It will be applied after a manual reboot.
The custom parameter group takes effect after the DB instance is manually rebooted.
The change is applied after a reboot, not after 24 hours, making this option incorrect.
I think the answer is:
After the DB instances are manually rebooted
I assess that the answer is:
After the DB instances are manually rebooted
