Alcatel-Lucent NRS I – Layer 2 Switching and Spanning Tree — Question 14

Which of the following best describes the relationship between locally configured policies and the direction of traffic?

Answer options

• A. Import policies affect the way the local AS receives traffic, while export policies affect the way it sends traffic.
• B. Import policies affect the way the local AS sends traffic, while export policies affect the way it receives traffic.
• C. Both import and export policies affect the way the local AS receives traffic, but not the way it sends traffic.
• D. Both import and export policies affect the way the local AS sends traffic, but not the way it receives traffic.

Correct answer: B

Explanation

The correct answer is B because import policies dictate how traffic is sent out from the local AS, while export policies control how incoming traffic is received. Option A incorrectly reverses the roles of import and export policies, while options C and D incorrectly suggest that one type of policy does not affect either sending or receiving traffic.
