Which statement is true regarding the Network Time Protocol (NTP) on Junos devices?
Click on the arrows to vote for the correct answer
A. B. C. D.A
The correct answer is C. The Junos OS can provide a primary time reference.
Explanation:
The Network Time Protocol (NTP) is a protocol used to synchronize the clocks of network devices. NTP is used to ensure that all devices on a network have the same time, which is important for many network operations.
The Junos OS supports the Network Time Protocol (NTP) and can act as an NTP client or an NTP server. When the Junos device acts as an NTP client, it can synchronize its clock with an NTP server. When the Junos device acts as an NTP server, it can provide time synchronization information to other devices on the network.
Option A is incorrect because the Junos OS supports the use of MD5 authentication for NTP, which provides secure communication between the NTP client and server.
Option B is incorrect because the Junos OS does support the server mode for NTP. In server mode, the Junos device acts as an NTP server and provides time synchronization information to other devices on the network.
Option D is incorrect because the Junos OS does support the use of a boot server. A boot server is used to provide boot files to devices during the boot process. The Junos OS can use a boot server to obtain the necessary files during the boot process.
Therefore, the correct answer is C. The Junos OS can provide a primary time reference.
