Nokia Certified Network Associate (NCNA) — Question 17

Which of the following statements about IP filters on a Nokia 7750 SR is TRUE?

Answer options

• A. Multiple ingress IP filters can be used on a single interface.
• B. An IP filter can be applied to the management port.
• C. The same IP filter can be used on multiple interfaces.
• D. Only one IP filter can be defined per router.

Correct answer: C

Explanation

The correct answer is C because an IP filter can indeed be applied to multiple interfaces, allowing for consistent traffic management across them. Option A is incorrect as it suggests multiple filters can be used on a single interface, which is not accurate. Option B is wrong because IP filters cannot be applied to the management port, and option D is false since multiple filters can exist on a router, but they can be reused across different interfaces.
