DANTE LEVEL 3 EXAMINATION TEST 2025/2026
QUESTIONS AND ANSWERS RATED A+
✔✔Dante devices remember their settings through power cycles, so they restore
functionality when they come back up. Of course, a subscription is made between a
transmitter and a receiver-so which device remembers the connections that need to be
made? - ✔✔The receiver
✔✔Scenario: You are the AV manager for a facility that has an auditorium, meeting
spaces, and background music/paging system all on a flat, Layer 2 network. There are
only about 40 devices and this is on a dedicated network, so it works just fine. The
technicians in the auditorium often change subscriptions on their devices as different
events roll through, but the other domains do not require custom patching much.
From time to time, the AV technicians mistakenly patch to devices in the meeting
spaces or BGM system. That in turn breaks patching that was already in pace. The
technicians don't always realize they made a mistake, at which point someone needs to
go and figure out what went wrong.
We could certainly use a dante preset to quickly restore the BGM and meeting spaces
when this sort of thing happens, but that is after the fact and after the problem has been
seen by others.
What could be done to prevent these - ✔✔Add dante domain manager, and place the
auditorium in a separate domain from the other functional groups.
✔✔In a network switch, imagine that two switch ports simultaneously receive data for
the same destination switch port. What happens? Assume no traffic management such
as QoS has been engaged. - ✔✔Whichever message processors see first will go first-
the other is placed in a queue and will be sent when bandwidth is available.
✔✔What is the range of DSCP values? - ✔✔0-56
✔✔If we were to engage QoS to prioritize PTP, which DSCP value should be elevated?
- ✔✔56
✔✔What IP range do multicast streams use? - ✔✔224.0.0.0/4
✔✔An ARP request is a ______ message, and the reply to that request is a_____
message. - ✔✔broadcast, unicast
✔✔How does multicast act without IGMP snooping? - ✔✔Acts like broadcast.
✔✔What port does multicast audio go to? - ✔✔UDP port 4321
, ✔✔You can see al the IP address and MAC address associations your system knows
about by going to the command line and typing: - ✔✔arp-a
✔✔Describe Layer 1-4 - ✔✔Layer 1: Hardware, electrical and optical connections
Layer 2: source and destination MAC addresses
Layer 3: source and destination IP addresses
Layer 4: Network protocol as well as source and destination IP port
✔✔Seven Layers of the OSI model - ✔✔1. Physical
2. Datalink
3. Network
4. Transport
5. Session
6. Presentation
7. Application
✔✔Which types of traffic will a router not pass? - ✔✔multicast, broadcast
✔✔True or false: DNS resolves a domain name to an IP address and IP port number. -
✔✔False
✔✔Scenario: A Dante system is using a mix of devices with 1Gbps and 100Mbps ports.
The system has been running continuously for a week, though the system operators
suggest they hard occasional audio distortion. You notice audio multicast bandwidth has
accumulated to 30 Mbps. What would be the most likely solution for this? - ✔✔Engage
IGMP snooping (and a querier).
✔✔True or false: switches can discover multiple MAC addresses though a single switch
port. - ✔✔True
✔✔When designing a Dante network from scratch, which of the following should be
considered? - ✔✔Sizing trunk lines for worst case traffic loads.
✔✔To forward a unicast message to its destination, a network switch examines the
packets_____ - ✔✔MAC address
✔✔Your device has an IP configuration of 10.01.1.116/24. You successfully ping a
device at 10.0.2.116. If you go to the command line and type arp-a, will 10.0.2.116 show
up in the ARP list? - ✔✔No
