Dante Level 2 Test Questions with
Solutions 2024
How does precision time protocol (PTP) work in dante devices? - -The clock
leader dstributes a very accurate date-time reference. Each follower derives
the required sample rate or frame rate from this leader.
-What is the golden rule for commissioning redundant networks? - -Work on
one network at a time, verify that devices are not set to switched mode
-How much switching capacity is needed for a switch with 10 1 Gbps ports? -
-20 Gbps-10 Gbps both ways on each port
-When would be a good time to consider engaging QoS? - -Whenever 100
Mbps dante devices are on the network
When ports begin to approach saturation, around 60-80%.
When we have traffic on a converged network, so there is something to de-
prioritize
-How many switches should be IGMP querier? - -Only one
-DSCP values range from 0-63. What is that used for in QoS? - -When
configuring the switch, you can determine which DSCP values will lead to
which queue.
-How can you monitor Dante traffic performance? - -Dante controller
latency screen-shows packet arrival times. Counts as a late packet if it
doesn't make it within the latency window.
-When should IGMP snooping or any multicast management be considered
for a dante network? - -When the estimated multicast bandwidth may
approach a network ports saturation point, impacting performance.
-TCP vs UDP - -TCP: A connection with delivery verification. Good for general
internet traffic where dropped packets are likely.
UDP: One way transmission with no delivery verification. Suitable for LANS
where traffic is under your control and interruptions are unlikely. Preferred
for real time networks for lower overhead and lower latency.
