Dante Level 2 Test Questions
How does precision time protocol (PTP) work in dante devices? - ANS -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? - ANS -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? - ANS -20
Gbps-10 Gbps both ways on each port
When would be a good time to consider engaging QoS? - ANS -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? - ANS -Only one
DSCP values range from 0-63. What is that used for in QoS? - ANS -When configuring
the switch, you can determine which DSCP values will lead to which queue.
How can you monitor Dante traffic performance? - ANS -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? - ANS -When the estimated multicast bandwidth may approach a network
ports saturation point, impacting performance.
TCP vs UDP - ANS -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.
