• C. Auto Scaling will execute the policy but it will not launch the instances until the process is resumed
• D. It is not possible to suspend the AlarmNotification process

Suspending the AlarmNotification process prevents Auto Scaling from executing scaling policies triggered by CloudWatch alarms. CloudWatch itself continues to function and generate alarms, meaning AWS receives them, but Auto Scaling will not act on them until the AlarmNotification process is resumed.
