Dante Level 2 exam QUESTIONS WITH ACTUAL CORRECT
DETAILED ANSWERS GRADED A +
How does precision time protocol (PTP) work in dante devices? - ANSWER-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? - ANSWER-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? - ANSWER-20 Gbps-
10 Gbps both ways on each port
When would be a good time to consider engaging QoS? - ANSWER-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? - ANSWER-Only one
, DSCP values range from 0-63. What is that used for in QoS? - ANSWER-When configuring the
switch, you can determine which DSCP values will lead to which queue.
How can you monitor Dante traffic performance? - ANSWER-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?
- ANSWER-When the estimated multicast bandwidth may approach a network ports saturation
point, impacting performance.
TCP vs UDP - ANSWER-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.
What happens when a multicast packet is sent on an unmanaged network? - ANSWER-The
multicast packet will propagate to every port on the network-will behave similarly to broadcast.
What is a converged network? - ANSWER-A network that carries multiple and possibly unrelated
data types (such as internet, VoIP, dante, etc.).
Describe a broadcast network transmission - ANSWER-A broadcast message transmits from one
to device to everyone on the network.
Is queue number priority low to high or high to low? - ANSWER-High to low number (higher
numbers have highest priority)
