What is the primary advantage of PTP over NTP in data center networks?

PTP requires no configuration on network switches

PTP provides higher precision through hardware timestamping and a master-slave hierarchy

PTP automatically synchronizes all devices without a master clock

PTP uses the same protocol as NTP but with a different port number

What does a large offset value in 'show ntp status' indicate?

The switch is using a high stratum server

The local clock is significantly different from the NTP server's time

The NTP authentication has failed

A data center engineer is configuring NTP on a Dell PowerSwitch. The switch has multiple VLAN interfaces, but the management network is on VLAN 100 with IP 192.168.1.10. The NTP server is at 192.168.1.200. The engineer wants to ensure that all NTP packets are sourced from the management interface. Which configuration command should be used?

ntp server 192.168.1.200 source 192.168.1.10

ntp broadcast client source 192.168.1.10

What does the PTP 'profile' setting on a Dell switch specify?

The list of allowed grandmaster clocks

The authentication method for PTP messages

The set of PTP options and defaults, such as message rates and transport

The physical layer used for PTP

In a PTP network, what role does a boundary clock play?

It only receives time from a master and never forwards it

It translates PTP messages to NTP for legacy devices

It synchronizes to an upstream master and acts as a master for downstream slaves

It provides a backup time source in case the grandmaster fails
