CONCEPTS!!!
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? -
(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.
Switches look at ________ - (answer)Destination MAC addresses to forward frames
Things to consider when building a network from scratch: - (answer)Sizing links for worst case traffic
loads
Dante automatically changes a unicast flow to a multicast flow when necessary. - (answer)False
Dante uses ______ DSCP tags. - (answer)4
Apart from separate cabling, a ________ can be used to separate broadcast domains. - (answer)VLAN
In a [________] transaction bandwidth is only consumed on the [________] path between a receiver
and a transmitter. - (answer)unicast, shortest
A session is ________ - (answer)an instance when a connection between two devices is created to
transfer data

A Dante device can have an unlimited number of receive flows. - (answer)False
How do you find out how many transmit flows you are using? - (answer)Tx tab in Dante controller
An ARP whohas message is ________ - (answer)Broadcast
Giving an external word-clock to a Dante device replaces its internal clock. - (answer)False
