   How does Synchronous Ethernet (SyncE) distribute frequency synchronization?

   • ABy adjusting the switch's CPU clock frequency
   • BBy encoding the clock signal in the physical layer bit stream
   • CBy sending time-of-day packets over the data plane
   • DBy using a separate out-of-band management network

   A manufacturing plant is deploying PTP on a Dell PowerSwitch for precise machine control. The network uses the default 1588 profile. The engineer has configured the switch as a boundary clock. The grandmaster clock is connected to the switch, and the switch is connected to several machines. After configuration, the machines report that they are synchronized to the switch, but the offset is higher than expected. The engineer suspects the issue is with the switch's PTP configuration. What is the most likely cause of the high offset?

   • AThe switch is configured as an ordinary clock instead of a boundary clock.
   • BThe PTP profile is set to the wrong type.
   • CThe PTP domain number is incorrect.
   • DHardware timestamping is not enabled on the switch's PTP ports.
