SNCF — Securing Networks with Firepower — Question 309

A network administrator notices that inspection has been interrupted on all non-managed interfaces of a device. What is the cause of this?

Answer options

• A. The value of the highest MTU assigned to any non-management interface was changed
• B. The value of the highest MSS assigned to any non-management interface was changed
• C. A passive interface was associated with a security zone
• D. Multiple inline interface pairs were added to the same inline interface

Correct answer: A

Explanation

The correct answer is A because changing the highest MTU value can disrupt packet flow and inspection on non-managed interfaces. Options B, C, and D do not directly affect the ability to inspect traffic on all non-managed interfaces in the same way that an MTU change does.
