NDANTE LEVEL 3 TEST QUESTIONS
UPDATED ACTUAL EXAM QUESTIONS
AND CORRECT ANSWERS
Describe follower, primary clock leader, and boundary clock - follower: a device that accepts a clock
from another source
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.
Are dante flows unicast or multicast by default? - Unicast
Does dante domain manager subscribe to other networks when the transmitter is multicast? - Yes. Dante
domain manager can take multicast from a transmitter and send it as unicast across a router to another
subnet.
A campus network has different subnets for each of the twenty buildings. A project calls for a system
design where Dante devices would be present in every building. The VLANs are connected by standard
inter-VLAN routing. Dante Domain Manager is present in the design.
Can we establish a single dante domain for all the background music and paging equipment across the
entire campus, throughout all subnets? - Yes. We will need to make sure we have enough flows to cover
the unicast feeds, but otherwise this is fine.
When we share sources from one domain to another, how much control do we have? - we have a choice
between sharing channels to all domains in a group, or for more customization, we can choose which
channels are available in each domain.
If all dante devises are enrolled in dante domain manager and a random person connects to your
network and launches dante controller, will they be able to see anything? - No. Dante controller will not
show any devices on DDM until you have entered your credentials.
How does dante controller discover a new device when it is first connected to the network? - dante
controller listens for an mDNS "discovery" announcement at 224.0/0/251:5353
You have a system design with about 1000 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? - Break the network into VLANs, use unique
subnets for each VLAN and connect them with inter-VLAN routing.
Add Dante Domain Manager to manage and coordinate devices across the layer 3 network.
When Troubleshooting a system, what order (in terms of concepts) do we start at and work off from? -
Connectivity---> clocking--->Subscriptions--->Latency
True or false: Dante devices have an unlimited number of receive flows. - False
When dante devices are in red on dante controller, what might this mean? - Dante devices are in a
different subnet than the computer running Dante Controller.
Dante controller might be expecting to see devices on the primary network, but it is connected to the
secondary (or vice versa).
What can you use to automatically discover a large number of devices across multiple subnets? - DNS-SD
color meanings - green: in a managed system, these channels are shared from a device in another
domain.
red: a dante device is discovered in the network, but it is in the wrong subnet or you have
primary/secondary reversed.
black: a normal dante device properly recognized on the network.
In a dante domain manager system, what happens if we enable unicast clocking for a second device in
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.
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
remembers the connections that need to be made? - The receiver
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.
