• B. preserves the confidentiality of traffic encrypted by IPsec
• C. maintains routing protocol adjacencies with local neighbors 46
• D. maintains remote management access to the router

Correct answer: C, D

Explanation

Securing the control plane ensures that routing protocol adjacencies with local neighbors are maintained, which is crucial for proper network communication.
