A technician adds the NTP service to a server and configures all network computers to...

The correct answer is C. Synchronized system clocks .

According to CompTIA A+ Core 1 220-1201 objectives under Networking and Server Services, NTP (Network Time Protocol) is used to synchronize the clocks of computers across a network to a common time source. This is critical for:

Ensuring accurate timestamps for logs and events.

Coordinating scheduled tasks across multiple systems.

Preventing authentication issues in environments that rely on time-based credentials (e.g., Kerberos).

Why the other options are incorrect:

A. Defined network transport protocols: NTP itself is a protocol that uses UDP, but its primary purpose is not defining transport protocols.

B. Enabled print services on the server: NTP does not relate to printing.

D. Defined server options in DHCP: NTP may be referenced by DHCP options, but the act of adding NTP to a server is focused on time synchronization, not DHCP configuration.
