Dante Level 2 Test Questions, all Solved 100%Correct with Verified Answers
How can trunk lines contact multiple VLANs? - ✔✔By "tagging" packets
It its best practice to have one untagged VLAN, the rest being tagged
TCP - ✔✔Like "signature required" mail, the sender gets a notification that the message was
received
Appropriate when communications are likely to be interrupted, when missing a packet would
invalidate the date, or when timely delivery is a convenience rather than a necessity
UDP - ✔✔Like "first class" mail, a message is put on the network and assumed to be
delivered successfully - no notification
Appropriate when communications are not likely to be interrupted (LAN), when a missing
packet in sequences can be overcome (error correction), or when timely delivery and/or low
overhead is a priority
UDP is ideal for real-time networks
Potential problems with TCP - ✔✔Creates additional overhead from confirmation messages,
increasing the likelihood of problems (not ideal for live Dante systems)
When Dante sends media across a network, which can be used? (select two)
- Unicast
,- Multicast
- Broadcast - ✔✔Unicast or Multicast
IGMP Snooping - ✔✔A tool for managing multicast traffic
Without IGMP Snooping, Multicast behaves like Broadcast
Unicast - ✔✔One-to-one transmission that can cross a router for transmission
Signal must be duplicated to send to multiple destinations, which can cause strain on
transmitters and switches
Best latency performance
Broadcast - ✔✔One-to-all transmission that does not cross the router (contained to LAN)
Generally used for locating devices (DHCP) rather than a means for communication
Multicast - ✔✔One-to-many transmission that does not cross the router (contained to LAN)
Transmissions will only go to destinations that need the communications
Better bandwidth management as channel count rises
IGMP Querier - ✔✔Keeps the master list of where all the Multicast subscriptions go
, Only one switch should be assigned as the IGMP Querier
Which versions of IGMP Snooping are supported by Dante? - ✔✔IGMP Snooping v2 or v3
Latency for Unicast - ✔✔Greater than or equal to 0.25 msec
Latency for Multicast - ✔✔Greater than or equal to 1.00 msec
How many audio channels are sent in a Unicast package? - ✔✔4 channels (24-bit, 48kHz,
1msec latency)
How many audio channels are sent in a Multicast package? - ✔✔8 channels
How much bandwidth does a Unicast flow take up? - ✔✔5-6 Mbps
Dante Flows - ✔✔How Dante interfaces manage resources for subscriptions
Quality of Service (QoS) - ✔✔Establishes queues to prioritize some traffic over others
The switch evaluates a "DSCP" tag
Which type of data is assigned the highest priority? - ✔✔Clocking
Which type of data is assigned medium priority? - ✔✔Audio / Video Data
Which type of data is assigned low priority? - ✔✔Control Data
