DANTE LEVEL 3 EVALUATION EXAM 2025/2026
QUESTIONS AND ANSWERS RATED A+
✔✔Match the clocking roles with their explanations
Clocking Roles:
- Primary Clock Leader
- Boundary Clock
- Follower
Explanations:
- A device that is the original time reference for all other devices on the network
- A device that accepts a clock from another source
- A device that accepts a clock from another source, then feeds that clock to other
devices - ✔✔Primary Clock Leader: A device that is the original time reference for all
other devices on the network
Boundary Clock: A device that accepts a clock from another source, then feeds that
clock to other devices
Follower: A device that accepts a clock from another source
✔✔Dante devices have an unlimited number of receive flows.
True
False - ✔✔False
✔✔What is the main purpose of using a GPS clock?
- It offers a steady time reference at any location on earth, overcoming the network jitter
of long-distance connections (Long distance can mean hundreds or thousands of miles)
- It solves the 24-hour clock roll-over problem in SMPTE time code
- The GPS clock inherently offers a more stable clock even if your network doesn't leave
the room - ✔✔It offers a steady time reference at any location on earth, overcoming the
,network jitter of long-distance connections (Long distance can mean hundreds or
thousands of miles)
✔✔In a Dante Domain Manager system, what happens if we enable unicast clocking for
a second device in the subnet?
- Clock problems will occur because both devices will try to be the clock leader for the
subnet
- VA clock leader will be elected for the subnet. The other device will be follower and will
be ready to take over in case the leader is no longer present in the network - ✔✔VA
clock leader will be elected for the subnet. The other device will be follower and will be
ready to take over in case the leader is no longer present in the network
✔✔Dante flows are multicast by default
- True
- False - ✔✔False
✔✔Dante devices remember their settings through power cycles, so they restore
functionality when they come back up. Of course, a subscription is made between a
transmitter and a receiver - so which device(s) remember the connections that need to
be made?
- Transmitters
- Receivers
- Transmitters and Receivers
- Dante Controller - ✔✔Receivers
✔✔In Dante Controller, devices (or streams) can show up in different colors to indicate
status. What do each one mean?
Colors:
- Red
- Green
- Black
, Status:
- Dante device is discovered on the network, but it is in the wrong subnet or you have
primary/secondary reversed
- In a managed system, these channels are shared from a device in another domain
- A normal Dante device properly recognized on the network - ✔✔Red: Dante device is
discovered on the network, but it is in the wrong subnet or you have primary/secondary
reversed
Green: In a managed system, these channels are shared from a device in another
domain
Black: A normal Dante device properly recognized on the network
✔✔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
