Why is accurate time synchronization important for network security?

It increases the bandwidth available to network devices

It prevents unauthorized users from accessing the network

It encrypts data as it travels across the network

It ensures log entries from different devices can be correlated accurately

A network administrator notices that authentication logs on multiple servers show login events with timestamps that are several minutes apart, even though the events occurred simultaneously. The servers are in the same data center and are configured to use the same NTP server. Which configuration change would best resolve this discrepancy?

Disable NTP on the servers and manually set the time.

Ensure the servers are on the same subnet as the NTP server.

Increase the NTP polling interval on the servers.

Configure the servers to use a more accurate time source, such as a GPS-based NTP server.
