Dante Level 2 Exam Questions with 100% Correct
Answers.
Local Area Network (LAN) - ANS Contacted directly through a Dante switch

Wide Area Network (WAN) - ANS Connects the network across a wider geographical
area. Is reached through a router (gateway)

What kind of notation do IP Addresses use? - ANS Dotted-Quad or Dot Decimal
Notation

Subnet - ANS A group of local IP addresses

Subnet Mask - ANS Helps determine what IP addresses are in our subnet

Should be an unbroken string of binary ones followed by zeros

A subnet mask of 255.255.255.0 can be abbreviated as "/24"

What is the range of numbers for IP addresses in dotted-quad form? - ANS 0-255

What is the range of numbers we can actually use when assigning IP addresses in
dotted-quad form? - ANS 1-254

Domain Name Service (DNS) - ANS Translates domain names into IP addresses

If multiples are on a list, the first one to return an answer is followed

Subnets reserved for use on a local network - ANS 192 . 168 . ___ . ___
10 . ___ . ___ . ___
172 . 16-31 . ___ . ___
169 . 254 . ___ . ___

What are the two primary DHCP settings? - ANS IP Range (a.k.a. DHCP pool) and
Lease Time (e.g. 24 hours)

What is the priority option for automatic IP addressing for Dante devices? - ANS DHCP
Server

If no DHCP server is found for automatic IP addressing, what is the back up plan? -
ANS Link Local

How does Link Local work? - ANS Assigns each device a random address in 169 . 254 .
___ . ___

,Sends an ARP request to ensure that an address is available

Once Link Local address is set, we continue looking for DHCP Service

VLAN - ANS Strategically isolates LANs on the same switch

Non-Blocking Architecture - ANS The switch is not the bandwidth bottleneck in the
network

Your only restriction is your individual port speed

Spanning Tree Protocol (STP) - ANS A protocol that disables a second trunk line
between the same two switches to prevent a Broadcast Storm

Broadcast Storm - ANS An endless loop of broadcast information. Like microphone
feedback but for broadcast

Link Aggregation Group (LAG) - ANS Allows trunk lines to be combined for more
bandwidth

How can trunk lines contact multiple VLANs? - ANS By "tagging" packets

It its best practice to have one untagged VLAN, the rest being tagged

TCP - ANS 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 - ANS 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 - ANS 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 - ANS Unicast or Multicast

IGMP Snooping - ANS A tool for managing multicast traffic

Without IGMP Snooping, Multicast behaves like Broadcast

Unicast - ANS 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 - ANS 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 - ANS 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 - ANS 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? - ANS IGMP Snooping v2
or v3

Latency for Unicast - ANS Greater than or equal to 0.25 msec

Latency for Multicast - ANS Greater than or equal to 1.00 msec

How many audio channels are sent in a Unicast package? - ANS 4 channels (24-bit,
48kHz, 1msec latency)

How many audio channels are sent in a Multicast package? - ANS 8 channels

How much bandwidth does a Unicast flow take up? - ANS 5-6 Mbps
