200-301: Cisco Certified Network AssociateDemo

Syslog severity 5 (Notice) flags routine but noteworthy state changes rather than a device-wide event. Cisco IOS logs a routing protocol adjacency dropping and re-establishing, a routing instance flapping, at this severity, for example via a %OSPF-5-ADJCHG message, which matches the notice classification being tested. Debug output is tied to severity 7, and an ARP inspection failure is logged as a warning/error condition rather than a notice.
