Dante Level 2 Questions and Answers Already Passed

Dante Level 2 Questions and Answers Already Passed When should IGMP snooping (or other multicast management) be considered for a Dante network? When the estimated multicast bandwidth may approach a network port's saturation point, impacting performance. A broadcast network transmission: transmits from one to everyone on the network. A network that carries multiple, possibly unrelated data types (like internet, VoIP, Dante, etc.) is: called a converged network. A multicast network transmission: can trim the distribution list with IGMP snooping. TCP: Good for general network UDP: Good for LANs that are under your control TCP UDP Dante multicast can be managed with IGMP Snooping v2 or v3. True Quality of Service (QoS) allows some traffic to be prioritized over others. When would be a good time to consider engaging QoS? (Select all that apply) 1. When we have traffic a converged network, so there is something to de-prioritize. 2. Only when using unmanaged switches. Suppose a switch has 8 queues on it. Which queue number would typically have the highest priority? 1 If you don't know the PIN to unlock a Dante device with "Device Lock" engaged, can it be recovered? Yes. Connect to the computer directly to the Dante device (or make sure the two are the only things connected to a switch) and wait two minutes. Dante Controller will then allow you to unlock the device. When commissioning or doing maintenance on a system with redundant networks, which is a good practice? Connect one network at a time, and verify that the devices are not set to switched mode. If a switch has 10x 1Gbps ports, how much switching capacity would a switch need to be considered "non-blocking"? 10gbps What can Dante Firmware Updater (part of Dante Controller) do for us? (Select all that apply.) 1. It can do a quick scan of devices on your network, compare it to our online database and tell you if firmware updates are available for any devices. 2. It can update the Dante firmware on a device, but check with the manufacturer's web site for update instructions. Some devices may require other firmware to be updated before the Dante firmware. When configuring IGMP Snooping, how many switches should be IGMP Querier(s)? One - there can be only one. If a multicast packet is sent on an unmanaged network, what will happen? The multicast packet will propagate to every port on the network - it will behave similarly to broadcast. DSCP values range from 0-63. What is that used for in QoS? When configuring the switch, you can determine which DSCP values will lead to which queue. If you mix switches with and without IGMP filter, what will happen? (Select all that apply) 1. Switches without IGMP will forward Multicast to all their ports. 2. Switches with IGMP will not forward unrequested Multicast. Is it possible to verify Dante traffic performance? Yes, Dante Controller's latency screen will show packet arrival times. If it doesn't make it within the latency window, it counts as a "late packet". Audinate engineers invented the idea of using Precision Time Protocol (PTP) to synchronize audio/video devices. How does it work? The clock leader distributes a date-time reference with incredible accuracy. Each device then derrives the required sample rates and/or frame rates from this date-time reference.
