DANTE Level 3 EXAM QUESTIONS WITH ACTUAL CORRECT
DETAILED ANSWERS GRADED A +
A 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? - ANSWER-
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) - ANSWER-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) - ANSWER-1 micro sec
If 3 channels are being sent within 1 unicast flow, how much bandwidth is being used? (sample
rate 48KHz/24-bit) - ANSWER-6mbps
Routers do not use IP addresses, they only use MAC addresses. - 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?
1 milli seconds - ANSWER-1 milli seconds
, A Dante device can have an unlimited number of receive flows. - 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
How much bandwidth does a unicast audio flow use? (Assume 48kHz, 24-bit.) - ANSWER-6mbps
A multicast flow is initiated by a transmitter alone. - ANSWER-TRUE
A switch populates its [...] by observing the source [...] of ARP requests and responses passing
through. - ANSWER-Mac Address Table
MAC Addresses
IGMP snooping listens for reports to [...] messages in order to restrict [...] traffic. - ANSWER-
IGMP query, multicast
The amount of bandwidth used by a multicast flow varies based on number of transmitting
channels. - ANSWER-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. -
ANSWER-FALSE
How can you find out how many transmit flows a device is using? - ANSWER-In Dante Controller,
go to Device View, Tx tab
Dante devices automatically change unicast flows to multicast when a fan-out is detected. -
ANSWER-False
