Dante Level 3 UPDATED Actual Exam
Questions and CORRECT Answers
SCENARIO: You have a Dante system that seems to be functioning correctly, there are no
external word clocks configured, no preferred master configured, but there are still a number
of devices that report they are losing sync occasionally. What steps would you take to find the
root cause of the problem? - CORRECT ANSWER- ✔✔-You suspect that multicast traffic is
not able to traverse the network in both directions (i.e. from master to all slaves, and from all
slaves to the master). To check if this is the case you enable unicast delay requests on the
slaves, then monitor the clock status histogram for evidence of disruption in PTP. When this
resolves the problem you suspect that ACLs blocking multicast on UDP ports 319 and 320 in
a direction from the slave to the master is to blame.
-If IGMP Snooping is enabled, you test the system with no audio and IGMP Snooping turned
off. When this resolves the problem you suspect that IGMP snooping has been interfering
with the distribution of multicast traffic between the slaves and the master. You enable unicast
delay requests on all slaves to reduce the amount of multicast traffic that the switches need to
track via IGMP.
