EXCELLENCE
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?
UDP 146
TCP 443
UDP 5353
UDP 4321
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)
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)
1 micro sec
If 3 channels are being sent within 1 unicast flow, how much bandwidth is being used? (sample rate
48KHz/24-bit)
,4mbps
8mbps
2mbps
6mbps
6mbps
Routers do not use IP addresses- they only use MAC addresses.
TRUE FLASE
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
1 milli seconds
A Dante device can have an unlimited number of receive flows.
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).
TRUE
How much bandwidth does a unicast audio flow use? (Assume 48kHz, 24-bit.)
6mbps
,A multicast flow is initiated by a transmitter alone.
TRUE
A switch populates its ________ by observing the source __________ of ARP requests and responses
passing through.
Mac Address Table
MAC Addresses
IGMP snooping listens for reports to __________ messages in order to restrict __________ traffic.
IGMP query, multicast
The amount of bandwidth used by a multicast flow varies based on number of transmitting channels.
FALSE
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.
FALSE
How can you find out how many transmit flows a device is using?
In Dante Controller, go to Device View, Tx tab
, Dante devices automatically change unicast flows to multicast when a fan-out is detected.
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?
Turn on IGMP Snooping
When a system will implement redundant networks, the preferred method for commissioning is:
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.
DSCP
A
firewall
can either permit or block a/an
IP address
or a port on a particular transport protocol.
FIREWALL, IP Address
A unicast flow is created by a transmitter alone.
FALSE
