CCNA: Cisco Certified Network Associate — Question 65

What event has occurred if a router sends a notice level message to a syslog server?

Answer options

• A. A certificate has expired
• B. An interface line has changed status
• C. A TCP connection has been torn down
• D. An ICMP connection has been built

Correct answer: B

Explanation

The correct answer is B because a notice level message typically indicates a change in the operational status of an interface. Options A, C, and D do not relate to interface status changes and are therefore not correct in this context.
