Which of the following servers would be used to maintain consistent time across all systems?

A DHCP server dynamically assigns IP addresses and other network configuration parameters to devices on a network, not responsible for time synchronization.

A proxy server acts as an intermediary for client requests to other servers, primarily for security, filtering, or caching, not for maintaining system time.

An NTP (Network Time Protocol) server is specifically designed and used to synchronize the clocks of networked computers. By querying an NTP server, client systems can adjust their internal clocks to maintain accurate and consistent time across an entire infrastructure.

A DNS server translates domain names into IP addresses, essential for network communication, but has no function in synchronizing system clocks.
