Implementing and Operating Cisco Enterprise Network Core Technologies (ENCOR) — Question 25

Which two mechanisms are available to secure NTP? (Choose two.)

Answer options

• A. IPsec
• B. IP prefix list-based
• C. encrypted authentication
• D. TACACS-based authentication
• E. IP access list-based

Correct answer: C, E

Explanation

The correct answers are C and E because encrypted authentication provides a secure way to verify NTP messages, ensuring their integrity and authenticity. IP access list-based methods control which devices can interact with the NTP server, adding an additional layer of security. The other options either do not specifically apply to NTP or are not mechanisms used to secure it.
