   What is the primary purpose of the Network Time Protocol (NTP) in a network environment?

   • ATo synchronize the clocks of network devices to a common time source
   • BTo prioritize network traffic based on time-of-day policies
   • CTo provide a backup routing path in case of link failure
   • DTo encrypt data transmitted between network devices

   A Dell switch is configured with two NTP servers: Server A (stratum 2) and Server B (stratum 3). The switch is currently synced to Server A. Server A becomes unreachable. What happens to the switch's clock?

   • AThe switch will fall back to Server B and sync to it, becoming stratum 4.
   • BThe switch will become a stratum 2 server itself.
   • CThe switch will stop providing time to its clients.
   • DThe switch will continue using its last known time from Server A.

   An administrator is configuring NTP on a Dell switch. The switch must use a specific source IP address (192.168.1.1) for all NTP packets so that firewall rules can be applied. Which command should be used?

   • Aip ntp source 192.168.1.1
   • Bntp peer 192.168.1.1
   • Cntp server 192.168.1.1
   • Dntp source 192.168.1.1

   A Dell switch is configured with NTP authentication. The administrator configures the NTP server with a key, but the switch is not synchronizing. The administrator checks 'show ntp status' and sees 'unsynchronized'. What is the most likely cause?

   • AThe switch's clock is already synchronized, so it stops sending requests.
   • BThe switch is configured in broadcast mode instead of client mode.
   • CThe NTP server is at a higher stratum than the switch.
   • DThe NTP key on the switch does not match the key on the server.

   A Dell switch is synced to an NTP server. The administrator notices that the switch's clock is consistently 10 ms ahead of the server. The administrator checks 'show ntp status' and sees the offset is 10 ms. What is the most likely cause of this consistent offset?

   • AThe switch's clock is not synchronized.
   • BThe NTP server is at a higher stratum than the switch.
   • CThe NTP polling interval is too long.
   • DThe network path between the switch and the server has asymmetric latency.
