CCNA: Cisco Certified Network Associate — Question 39

Which two tasks must be performed to configure NTP to a trusted server in client mode on a single network device? (Choose two.)

Answer options

• A. Enable NTP authentication.
• B. Verify the time zone.
• C. Specify the IP address of the NTP server.
• D. Set the NTP server private key.
• E. Disable NTP broadcasts.

Correct answer: A, C

Explanation

Enabling NTP authentication (A) ensures that the client only trusts time information from authenticated servers, which is crucial for security. Specifying the IP address of the NTP server (C) is necessary to direct the client to the correct time source, while the other options do not directly contribute to the configuration process for establishing a trusted NTP client-server relationship.
