Developing Applications and Automating Workflows Using Cisco Platforms (DEVASC) — Question 337

Which protocol is used for clock synchronization between network devices?

Answer options

• A. FTP
• B. NNTP
• C. BGP
• D. NTP

Correct answer: D

Explanation

The correct answer is NTP (Network Time Protocol), which is specifically designed for synchronizing clocks across networked devices. FTP, NNTP, and BGP serve different purposes: FTP is for file transfer, NNTP is for network news transfer, and BGP is a routing protocol, none of which relate to clock synchronization.
