SNCF — Securing Networks with Firepower — Question 317

An engineer configures a network discovery policy on Cisco FMC. Upon configuration, it is noticed that excessive and misleading events are filling the database and overloading the Cisco FMC. A monitored NAT device is executing multiple updates of its operating system in a short period of time. What configuration change must be made to alleviate this issue?

Answer options

• A. Exclude load balancers and NAT devices.
• B. Leave default networks.
• C. Increase the number of entries on the NAT device.
• D. Change the method to TCP/SYN.

Correct answer: A

Explanation

The correct answer is A because excluding load balancers and NAT devices helps reduce unnecessary events from being logged, which can overwhelm the system. Options B and C do not address the specific issue of misleading events, and D does not resolve the problem regarding the excessive updates from the NAT device.
