Question

Which of the following protocols are used to provide accurate time to network devices?

Options

ASMTP
BFTP
CTLS
DNTP

Explanation

NTP (Network Time Protocol) is the standard protocol used to synchronize clocks across networked devices to a common time source (e.g., an atomic clock or internet time server). Accurate time is critical for log correlation, authentication protocols (Kerberos, certificates), and scheduled tasks. The other protocols serve entirely different purposes: SMTP (Simple Mail Transfer Protocol) is for sending email; FTP (File Transfer Protocol) is for transferring files; TLS (Transport Layer Security) is a cryptographic protocol that provides encrypted communication but is not used for time synchronization.
