DANTE Level 3 - 2020A Dante system is running on a converged enterprise network. Clocking and discovery
are working OK, but audio only passes in unicast. You conclude that a firewall is
blocking your multicast audio packets. What port would you ask the IT administrator to
unblock? - ANS -UDP 4321
If 5 unicast channels are sent between two devices, how much bandwidth, and how
many flows are being used? (sample rate 48KHz/24-bit) - ANS -12 mbps, and 2 flows
Dante media clock synchronization is more accurate than [...] between any two devices
on the network (Select the most accurate variance we guarantee) - ANS -1 micro sec
If 3 channels are being sent within 1 unicast flow, how much bandwidth is being used?
(sample rate 48KHz/24-bit) - ANS -6mbps
Routers do not use IP addresses, they only use MAC addresses. - ANS -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?
1 milli seconds - ANS -1 milli seconds
A Dante device can have an unlimited number of receive flows. - ANS -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). - ANS -TRUE
How much bandwidth does a unicast audio flow use? (Assume 48kHz, 24-bit.) - ANS
-6mbps
A multicast flow is initiated by a transmitter alone. - ANS -TRUE
A switch populates its [...] by observing the source [...] of ARP requests and responses
passing through. - ANS -Mac Address Table
MAC Addresses
IGMP snooping listens for reports to [...] messages in order to restrict [...] traffic. - ANS
-IGMP query, multicast
, The amount of bandwidth used by a multicast flow varies based on number of
transmitting channels. - ANS -TRUE
When you know you will be configuring switches with features like IGMP Snooping,
there is no hesitation in combining managed switches from different manufacturers in
your design. - ANS -FALSE
How can you find out how many transmit flows a device is using? - ANS -In Dante
Controller, go to Device View, Tx tab
Dante devices automatically change unicast flows to multicast when a fan-out is
detected. - ANS -False
A Dante system is using a mix of Brooklyn II (1Gbps) and Ultimo (100Mbps) devices.
The system has run continuously for at least 5 days, though system operators suggest
they hear occasional sound distortions. You notice audio multicast bandwidth has
accumulated to 90Mbps. What would be the potential solution for this? - ANS -Turn on
IGMP Snooping
When a system will implement redundant networks, the preferred method for
commissioning is: - ANS -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.
Diffserv QoS uses [...] tags. - ANS -DSCP
A [...] can either permit or block a/an [...] or a port on a particular transport protocol. -
ANS -FIREWALL, IP Address
A unicast flow is created by a transmitter alone. - ANS -FALSE
Your Dante network is working great. Dante Controller works fine on one computer, but
another computer only shows device names... even when you use the same network
cable/port for each computer. What are potential cause(s) of this? - ANS -All The
Above
DSCP stands for.... - ANS -Differentiated Services Code Point
