Dante Level 2 | 2024 Updated Graded A+ 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 IGMP Snooping - Answer -A tool for managing multicast traffic Without IGMP Snooping, Multicast behaves like Broadcast Unicast - Answer -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 - Answer -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 - Answer -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
