Implementing and Operating Cisco Enterprise Network Core Technologies (ENCOR) — Question 788

An engineer must configure interface and sensor monitoring on a router. The NMS server is located in a trusted zone with IP address 10.15.2.19. Communication between the router and the NMS server must be encrypted and password-protected using the most secure algorithms. Access must be allowed only for the NMS server and with the minimum permission levels needed. Which configuration must the engineer apply?

Answer options

Correct answer: B

Explanation

Option B is the correct choice because it utilizes a standard access-list that allows only the NMS server's IP address and employs strong authentication and encryption methods (SHA and AES 256). The other options either do not restrict access appropriately, use weaker encryption, or provide unnecessary permissions that exceed the minimum required for the task.
