Dante Level 2 exam questions and answers

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