   A network administrator needs to implement a critical security patch on a firewall. The patch addresses a vulnerability that is actively being exploited. The company's change management policy requires a 72-hour notice for standard changes, but it also has a provision for emergency changes. The administrator has verified the patch is stable and has a rollback plan. What is the MOST appropriate action?

   • AClassify the change as an emergency, obtain expedited approval, and implement the patch immediately.
   • BApply the patch to a test firewall first and wait for the next scheduled maintenance window.
   • CWait the full 72 hours for standard approval to follow the policy exactly.
   • DImplement the patch without any change request, since it is a security fix.
