Troubleshooting and Maintaining Cisco IP Networks (TSHOOT, legacy) — Question 38

Refer to the shown below.
%LINK-3-UPDOWN: Interface Serial0/0, changed state to up
%LINEPROTO-5-UPDOWN: Line protocol on Interface Serial0/0, changed state to up
What statement is correct regarding the output shown in the graphic?

Answer options

• A. These two log messages will not have a severity level. They are not errors but are just informational messages.
• B. The first log message is categorized as a warning message.
• C. These messages regarding interface status are normal output and will always be displayed when you exit config mode.
• D. The first log message is an error message with a severity level of 3.

Correct answer: D

Explanation

The first log message, indicating a state change, is assigned a severity level of 3, which categorizes it as an error message, making option D correct. Options A and B are incorrect because they mischaracterize the nature of the log messages, and option C is misleading since these messages can appear independently of exiting config mode.
