Question 240
An enterprise network designer recommends: Apply the correct policy to the intended BGP group or neighbor export statement. Which situation most clearly calls for this action?
Explanation
Correct Answer
This case requires the BGP policy placement action. The BGP advertisement decision begins using the configured routing policy.
Incorrect Answers
This other case would be better matched to Configure an export policy that explicitly accepts the approved aggregate and rejects all other routes. BGP advertisements to the ISP are constrained to the permitted external prefix.
This other case would be better matched to Add an explicit export reject for the prohibited internal prefix range before a broad allow rule. The external peer does not receive the prohibited internal networks from that policy.
This other case would be better matched to Place the critical reject policy before the permissive acceptance rule or refactor matching. Evaluation reaches the security restriction before a terminating accept action.
