DANTE LEVEL 3 COMPREHENSIVE EXAMS 2025/2026
QUESTIONS AND ANSWERS RATED A+
✔✔Scenario: Someone shows you messages in Dante Controller indicating the clock
leader is changing hands frequently. Dante Controller has been online for a long time...
and it does show a clock histogram with "blades of grass" spread over a moderate
range. What might you check?
- Probably a bad clock leader. Select a different device as Preferred Leader
- Probably too much multicast traffic. Establish an ACL to block streams from
224.0.0.230-224.0.0.233, ports 8700-8708
- This may not be a prob - ✔✔This may not be a problem at all. It could be that devices
were added or removed from the network, triggering clock elections. Dante Controller
just showed that normal activity. Clear the history and graphs, and watch for stability,
now
✔✔Scenario: You have a very large Dante deployment that will span multiple subnets.
You really don't want to enter all the device IP addresses manually - what can you use
to automatically discover devices across subnets?
- HTTPS
- DNS-SD
- LDAP
- SNMP
- mDNS - ✔✔DNS-SD
✔✔In Dante Controller or Dante Domain Manager, we can see icons with a "forked
arrow". What does the forked arrow mean?
- A connection is broken - the transmitter is "lost" and cannot find its destination
- We suspect an IP conflict, as we are only receiving some packets from the transmitter.
We suspect others are being routed elsewhere
- The connection is made by unicast
- The connection is made by multicast - ✔✔The connection is made by multicast
, ✔✔Scenario: You are the AV manager for a facility that has an auditorium, meeting
spaces, and background music/paging system all on a flat, Layer 2 network. There are
only about 40 devices and this is on a dedicated network, so it works just fine. The
technicians in the auditorium often change subscriptions on their devices as different
events roll through, but the other domains do not require custom patching much.
Problem: From time to time, the AV technicians mistakenly and patch to devices in -
✔✔Add Dante Domain Manager, and place the auditorium in a separate domain from
the other functional group(s)
✔✔You have a system managed by Dante Domain Manager. A Dante device is set to
transmit an audio channel by multicast, but you make a subscription to a device in
another subnet. Will this work?
- Yes, Dante Domain Manager will cause the transmitter to resend that channel as a
unicast stream for the subscription
- No, it is necessary to remove the channel from the multicast stream so that it can be
sent via unicast - ✔✔Yes, Dante Domain Manager will cause the transmitter to resend
that channel as a unicast stream for the subscription
✔✔Scenario: All your Dante devices are enrolled in Dante Domain Manager. A random
person connects to your network, and launches Dante Controller. What do they see?
- They won't see anything. Dante Controller will be blank, as if there were no devices on
the network
- They will see a list of devices, but they can't do anything to them
- They will see a list of devices, but they can only change subscriptions. They can't
change IP configuration or clocking
- They can only see event logs from the - ✔✔They won't see anything. Dante Controller
will be blank, as if there were no devices on the network
✔✔You have a system design with about a thousand devices spread across a property.
The IT administrator insists you segment the broadcast domain. You know audio/video
signals need to flow between major systems throughout the property. What steps do
you need to do? (Select all that apply)
- Ask for one massive VLAN spanning the entire property with a /22 subnet mask
(255.255.248.0) to allow over 1000 devices
