How is a unicast flow created in a Dante network? After the
user designates a subscription, a control message is sent to... -
ANSWER-the transmitter, asking it to start transmitting the
media stream for any device on the network to request.
When a system will implement redundant networks, the
preferred method for commissioning is: - ANSWER-Bring one
network online at a time, ensuring devices are property set for
redundant and you have the expected operation on each
network. Once you are satisfied, bring both networks online
together.
Dante Controller provides a diagnostic graph for checking the [
? ] of flows between two devices. - ANSWER-Latency
If 3 channels are being sent within 1 unicast flow, how much
bandwidth is being used? (sample rate 48KHz/24-bit) -
ANSWER-6mbps
,From the perspective of link bandwidth, unmanaged multicast
traffic behaves like: - ANSWER-Broadcast
If two different devices try to transmit to a common device at
the same time, switches suffer from a problem in the collision
domain. The packets are not readable and, in effect, dropped.
The original transmitters each wait a random amount of time to
retransmit in hopes of having a clear path. This is a common
problem in modern network switches. - ANSWER-False
On a Unicast transmission, a transmitter and receiver have
latency settings of 0.25 msec and 1.00 msec, respectively.
When will the audio playout of the receiving device? -
ANSWER-1 milli seconds
PTP sync traffic is the most time critical traffic in a Dante
network and is tagged with DSCP ______. - ANSWER-56
Switches can have multiple MAC addresses mapped to a port in
their MAC address table - ANSWER-True
A multicast flow is initiated by a transmitter alone. - ANSWER-
True
,In a production network, multicast management is more critical
than QoS. - ANSWER-True
Dante uses ______ for clocking. - ANSWER-PTP
To start a multicast flow in Dante Controller, a control message
is sent to... - ANSWER-the transmitter, asking it to start
transmitting the media stream for any device on the network to
request.
You have a new device with a Brooklyn II module, capable of
transmitting 64 channels. What is the minimum number of flows
needed to transmit all 64 audio channels in unicast to a single
receiving device? - ANSWER-16 flows
When a Dante enabled device is plugged into a network, how
does Dante Controller discover it? - ANSWER-By listening to
the device's announcement using mDNS
It is highly recommended for the backplane of a switch to be
able to accommodate full bandwidth use of all ports in both
directions. - ANSWER-True
All managed switches come from the factory with all of their
configuration settings disabled. - ANSWER-False
, SCENARIO: After setting up the network, you open Dante
controller. You notice that one device's name appears in Dante
Controller, but other control and status information is not
available. What is the likely cause of this issue? - ANSWER-
Device is in a different IP subnet than the Dante Controller
compute
Dante requires strict priority queuing when QoS is used. -
ANSWER-True
Giving an external word-clock to a Dante device replaces all
internal clocking mechanisms. - ANSWER-False
It is a best practice (and strongly suggested) to designate
unique IP subnets to each VLAN. Among other things, you'll be
able to use a router to connect the devices across VLANs (via
unicast). - ANSWER-True
QoS protects against too much bandwidth being used on a link
by a collection of systems. Even if the overload happens over
an extended period of time, packets are delivered in a timely
manner, regardless of their QoS priority queue. - ANSWER-
False
