A network administrator wants to ensure that all network devices in their organization have their internal clocks synchronized to prevent issues with log correlation and security timestamps. Which protocol should be implemented?
- ASNMP
- BDHCP
- CNTP
- DQoS
Show answer & explanationAnswer & explanation
Correct answer: C. NTP
NTP (Network Time Protocol) is specifically designed to synchronize the clocks of computer systems over packet-switched, variable-latency data networks. Accurate time synchronization is crucial for log correlation and security auditing.
Why the other options are wrong
- A. SNMP is for network management and monitoring, not time synchronization.
- B. DHCP is for IP address assignment, not time synchronization.
- D. QoS (Quality of Service) prioritizes network traffic, not time synchronization.
NTP (Network Time Protocol)
A networking protocol for clock synchronization between computer systems over packet-switched, variable-latency data networks.
- Synchronizes time across devices.
- Uses UDP port 123.
- Crucial for log analysis and security.
Memory trick: NTP: Never Tardy Protocol, keeps time perfect.
