- Frames from PC1 will cause the interface to shut down immediately, and a log entry will be made.
- Frames from PC1 will be forwarded to its destination, and a log entry will be created.

Answers Explanation & Hints:
Manual configuration of the single allowed MAC address has been entered for port fa0/12. PC1 has a different MAC address and when attached will cause the port to shut down (the default action), a log message to be automatically created, and the violation counter to increment. The default action of shutdown is recommended because the restrict option might fail if an attack is underway.
