What does NTP stand for?
Network Time Protocol
NTP is used to synchronize clocks across devices on a network.
Why is it critical for devices on a network to use the same timestamp?
To compare log files and information from multiple devices accurately
Having synchronized timestamps helps in troubleshooting and data analysis.
What is the default UDP port used by NTP servers?
123
This port is used for time requests from NTP clients.
What role does an NTP client play?
Queries the NTP server for time updates
The client is responsible for obtaining the latest time information.
True or false: An NTP server modifies its own time.
FALSE
An NTP server does not change its own time; it queries another NTP server if needed.
What is Network Time Security (NTS) used for?
Adds authentication to NTP responses
NTS ensures that the time information received is trustworthy.
What is the purpose of the NTS key exchange server?
Authenticates clients and provides a cookie for NTP queries
This server is part of the two-step process for secure time synchronization.
What is the accuracy of a local NTP server?
Around 10 milliseconds
This level of accuracy is sufficient for many applications.
What does PTP stand for?
Precision Time Protocol
PTP provides time synchronization with granularity down to the nanosecond.
Why might PTP be necessary in certain environments?
For very precise time synchronization, especially in industrial uses
PTP requires dedicated hardware for optimal performance.
