DANTE LEVEL 3 TEST PAPER 2025/2026 QUESTIONS AND
ANSWERS RATED A+
✔✔In Level 3, we learned there are many connections working together to create the
Dante functionality. Match the network connection with the associated multicast flow
Network Connections:
- Dante Traffic Monitoring
- Discovery
- Audio/Video Streams (multicast)
- Clocking (sync)
- Clocking (PTP logging)
Multicast Flow:
- 239.254.3.3:9998
- 224.0.0.230 to 224.0.0.233, ports 8700 to 8708
- 224.0.1.129 to 224.0.1.132, ports 319 and 320
- 239.255.x.x, port 4321
- 224.0.0.251:5353 - ✔✔Dante Traffic Monitoring - 224.0.0.230 to 224.0.0.233, ports
8700 to 8708
Discovery - 224.0.0.251:5353
Audio/Video Streams (multicast) - 239.255.x.x, port 4321
Clocking (sync) - 224.0.1.129 to 224.0.1.132, ports 319 and 320
Clocking (PTP logging) - 239.254.3.3:9998
✔✔In a network switch, imagine that two switch ports simultaneously receive data for
the same destination switch port. What happens? (Assume no traffic management has
been engaged.)
, - The message from the lowest switch port wins - the message from the highest port is
dropped
- The messages collide, and neither makes it through
- Whichever message the processors sees first will go first - the other is placed in a
queue and will be sent when bandwidth is available - ✔✔Whichever message the
processors sees first will go first - the other is placed in a queue and will be sent when
bandwidth is available
✔✔In this Level 3 class, we focused primarily on the bottom four layers of the network
protocol. Match up those layers with what they referred to.
- Layer 1
- Layer 2
- Layer 4
- Layer 3
- hardware, electrical and optical connections, etc.
- source and destination IP addresses
- source and destinati - ✔✔Layer 1 - hardware, electrical and optical connections, etc.
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
✔✔When designing a Dante network from scratch, which of the following should be
considered?
- Avoid using only one switch
- Sizing trunk lines for worst case traffic loads
- Avoid redundant networks when possible
- Avoid IGMP snooping - ✔✔Sizing trunk lines for worst case traffic loads
