Question

Which of the following statements are true regarding NTP when implemented on Cisco devices?

1) NTP is used to synchronize the time on Cisco devices.
2) NTP can be configured on both routers and switches.
3) NTP uses UDP port 123 for communication.
4) NTP can only be implemented on Cisco routers.
5) NTP can be used to synchronize time across different time zones.

Answer 1

NTP is used for time synchronization on Cisco devices, works on both routers and switches, communicates via UDP port 123, and manages time across different time zones. The only false statement is that NTP is exclusive to routers.

Step-by-step explanation:

The student has asked about the properties of Network Time Protocol (NTP) when used on Cisco devices. Here's what's true:

1. NTP is used to synchronize the time on Cisco devices.
2. NTP can be configured on both routers and switches.
3. NTP uses UDP port 123 for communication.
4. NTP can be implemented on a wide range of Cisco devices, not just routers.
5. NTP can be used to synchronize time across different time zones.

Hence, statements 1, 2, 3, and 5 are true regarding NTP on Cisco devices while statement 4 is not true as NTP is not limited to only routers.
