DANTE LEVEL 3 CERTIFICATION EXAM PRACTICE
QUESTIONS COMPLETE WITH 100% VERIFIED ANSWERS
1. What is the maximum bitrate for a single Dante Ethernet
connection?
A) 1 Gbps
B) 1.65 Gbps
C) 2.5 Gbps
D) 10 Gbps
Answer: B – The maximum bitrate for a single Dante Ethernet
connection is 1.65 Gbps (gigabits per second).
2. Which IP address type is used by Dante devices to send audio
streams to all devices on the same subnet?
A) Unicast
B) Multicast
C) Broadcast
D) Anycast
Answer: B – Dante audio traffic is transmitted using IPv4 multicast
addresses (typically 239.255.x.x) so that multiple receivers can listen
without generating separate unicast streams.
3. In a Dante network, what is the primary purpose of the subnet
mask?
A) Identify the default gateway
B) Define the network portion of an IP address
C) Assign a DNS server
,D) Enable DHCP lease renewal
Answer: B – The subnet mask determines which bits of an IP address
represent the network versus the host, allowing devices to determine if
another address is on the same subnet.
4. Which CIDR notation represents a network that can contain up to
510 hosts?
A) /23
B) /24
C) /22
D) /25
Answer: A – /23 provides 2^(32-23)-2 = 510 usable host addresses (512
total minus network and broadcast).
5. When configuring a Dante Domain Manager (DDM) server cluster
for high availability, which component must be identical on each
node?
A) MAC address of the NIC
B) Hostname of the server
C) DDM license key and database configuration
D) Static IPv6 address only
Answer: C – All cluster nodes must share the same DDM license and
database configuration so they can synchronize state and provide
seamless failover.
6. Which OSI layer is responsible for routing Dante traffic between
different subnets?
A) Layer 1 – Physical
B) Layer 2 – Data Link
C) Layer 3 – Network
,D) Layer 4 – Transport
Answer: C – Routing between different subnets occurs at Layer 3
(Network layer) of the OSI model.
7. What is the primary function of the RTS (Routing Table Server) in a
Dante network?
A) To manage the network topology
B) To allocate and manage audio streams
C) To synchronize clock and timing
D) To perform IP routing
Answer: B – The RTS is responsible for allocating and managing audio
streams in a Dante network, utilizing the Dante network protocol.
8. What is the purpose of the Dante ULB (Ultimate Low Bitrate)
protocol?
A) To reduce latency
B) To increase bit depth
C) To reduce bit depth at low load conditions
D) To improve network reliability
Answer: C – The Dante ULB protocol reduces the bit depth of the audio
signal during low load conditions to conserve network bandwidth.
9. 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?
A) UDP 5353
B) UDP 4321
C) TCP 443
, D) UDP 319
Answer: B – Multicast audio in Dante uses UDP port 4321.
10. If 5 unicast channels are sent between two devices, how much
bandwidth and how many flows are being used? (sample rate
48KHz/24-bit)
A) 6 mbps, 1 flow
B) 12 mbps, 2 flows
C) 12 mbps, 5 flows
D) 30 mbps, 5 flows
Answer: C – At 48kHz/24-bit, each unicast flow carries up to 4 channels
at 6 mbps. Five channels require 2 flows (one with 4 channels, one with
1 channel), totaling approximately 12 mbps.
11. What is the most accurate time variance guaranteed by Dante
media clock synchronization between any two devices on the
network?
A) 10 micro seconds
B) 5 micro seconds
C) 1 micro second
D) 100 nano seconds
Answer: C – Dante media clock synchronization guarantees accuracy
within 1 micro second between any two devices on the network.
12. If 3 channels are being sent within 1 unicast flow, how much
bandwidth is being used? (sample rate 48KHz/24-bit)
A) 3 mbps
B) 6 mbps
C) 9 mbps
D) 12 mbps
