Which two actions should an administrator perform with Case escalation rules?

Case escalation rules are used to escalate cases that have not been resolved within a certain time frame by changing the case owner, sending email notifications, or triggering workflow actions. You can use these actions to alert the appropriate users or groups when a case needs urgent attention or escalation.
