Dante Level 2 Comprehensive
Questions (Frequently Most
Tested) with Verified Answers.
Local Area Network (LAN) - Answer: Contacted directly through a Dante switch
Wide Area Network (WAN) - Answer: Connects the network across a wider geographical area. Is reached
through a router (gateway)
What kind of notation do IP Addresses use? - Answer: Dotted-Quad or Dot Decimal Notation
Subnet - Answer: A group of local IP addresses
Subnet Mask - Answer: 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? - Answer: 0-255
What is the range of numbers we can actually use when assigning IP addresses in dotted-quad form? -
Answer: 1-254
Domain Name Service (DNS) - Answer: 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 - Answer: 192 . 168 . ___ . ___
,10 . ___ . ___ . ___
172 . 16-31 . ___ . ___
169 . 254 . ___ . ___
What are the two primary DHCP settings? - Answer: 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? - Answer: DHCP Server
If no DHCP server is found for automatic IP addressing, what is the back up plan? - Answer: Link Local
How does Link Local work? - Answer: 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 - Answer: Strategically isolates LANs on the same switch
Non-Blocking Architecture - Answer: The switch is not the bandwidth bottleneck in the network
Your only restriction is your individual port speed
Spanning Tree Protocol (STP) - Answer: A protocol that disables a second trunk line between the same
two switches to prevent a Broadcast Storm
Broadcast Storm - Answer: An endless loop of broadcast information. Like microphone feedback but for
broadcast
Link Aggregation Group (LAG) - Answer: Allows trunk lines to be combined for more bandwidth
, How can trunk lines contact multiple VLANs? - Answer: By "tagging" packets
It its best practice to have one untagged VLAN, the rest being tagged
TCP - Answer: 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 - Answer: 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 - Answer: 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 - Answer: Unicast or Multicast
