Dante 3 Certification Questions Dante uses ___ for clocking - ✔✔PTP Switches can ____ data if there is contention on an interface. - ✔✔Queue OSI model is a - ✔✔Conceptual model The Multicast Bandwidth indicator in Dante Controller keeps track of: - ✔✔The amount of audio multicast traffic that you've created on the Dante network You have purchased a Dante-enabled device with a Brooklyn2 inside. How many unicast flows are needed to transport 64 audio channel? - ✔✔16 flows The BEST way to bring up a redundant network online is: - ✔✔Bring the primary network online first, ensure all devices appear functional, check that devices are configured to operate in redundant mode, then bring the secondary network online. QoS protects against unexpected temporary peaks in bandwidth that may affect time critical services. - ✔✔True Routers do not use IP addresses, they only use MAC addresses - ✔✔False A switch connects its interfaces together by referencing its - ✔✔MAC address table If 3 channels are being sent within 1 unicast flow, how much bandwidth is being used - ✔✔6mbps Dante devices have a set number of flows - ✔✔True A [Firewall] can either permit or block a/an [IP address] or a port on a particular transport protocol. - ✔✔ A unicast Dante flow allows for the use of much lower latency settings than a multicast flow. - ✔✔True In a production network. multicast management is more critical than QoS - ✔✔True Dante uses___DSCP tags - ✔✔4 In a [Unicast] transaction, bandwidth is only used between a [receiver] and a transmitter when an active subscription is made - ✔✔ A 802.1q tag is part of the VLAN frame header at layer - ✔✔2 What is the key aim of a network? - ✔✔Interoperability Strict queuing is preferred for real time services. - ✔✔True Network bandwidth is measured in - ✔✔bps (bits per second) A Dante receiving device has a latency setting of 1 ms. A Dante transmitting device has a latency setting of 1ms. If a subscription is created between these units, when will the audio playout of the receiving device? - ✔✔1 milli second It is recommended for the backplane of a switch to be able to accommodate full bandwidth use of all ports in obth directions. - ✔✔True Dante flows are multicast by default - ✔✔False 32 multicast IP addresses map to one multicast MAC address. - ✔✔True Switches can have multiple MAC addresses mapped to an interface in their MAC address table - ✔✔True A router will not pass - ✔✔Broadcast traffic An application has a port/socket address which pertains to a transport protocol which in turn is encapsulated into a packet, which has an [IP address], which is then encapsulated into an address frame which has a [MAC address]. - ✔✔ Which steps need to be taken in order to segment a broadcast domain? - ✔✔Put the same type of devices into a VLAN Define VLAN as an IP subnet Dante media clock sync is better than - ✔✔1 micro second between any two devices on the entire network IGMP snooping listens for reports to [IGMP query] messages in order to restrict [multicast] traffic. - ✔✔ Which of the following situations call for QoS to be turned on? - ✔✔Using Dante on a 100MB network Dante being used on a converged enterprise network Multicast uses specific [IP address] to indicate it is [multicast] - ✔✔ Giving an external word-clock to a Dante device replaces its internal clock. - ✔✔False QoS will not have a positive effect on constant bandwidth services. - ✔✔True From a link bandwidth use perspective, Unmanaged multicast domain behaves like - ✔✔Broadcast A unicast flow is created by a transmitter alone - ✔✔False A Dante receiving device has a latency setting of 1ms. A Dante transmitting device has a latency setting of 250us. If a subscription is created between these units, when will the audio playout of the receiving device? - ✔✔1 milli seconds You oversee a facility which contains many Dante devices. The audio distribution of the facility requires you to use several multicast Dante flows. Around 30% of the devices use Brooklyn2. The remaining devices use Ultimo. The system has been running continuously for at least 5 days. You notice the system is passing audio, but with occasional sound distortions. As the first step of your trouble shooting process, you look at the multicast bandwidth usage on the status bar in Dante Controller. It indicates that you have 90 bps of multicast traffic on the network. What would be the potential solution for this? - ✔✔Turn on IGMP snooping Higher link speeds allow fames to be cleared quicker through an interface. - ✔✔Ture What is the maximum number of channels that may be contained in a unicast flow? - ✔✔4 QoS protects against too much bandwidth being used on a link. - ✔✔False You notice that audio on your Dante network is not working as it should, but only when multicast transmission is configured for audio. Your audio network is on a convered enterprise network. After testing your Dante network. you conclude that a firewall is dropping your multicast packets. WHat port would you ask the IP administrator to unblock? - ✔✔UDP 4321 What protocol does Dante use to addign IP addresses to devices? - ✔✔DHCP IPv4 link local The CPU in a switch can slow down multicast traffic when IGMP snooping is enabled - ✔✔True A reply to ARP whohas message is - ✔✔Unicast ARP stands for - ✔✔Address resolution Protocol The three layer hierarchical model describes a model for network topology - ✔✔True A Dante device can have an unlimited numver of receive flows. - ✔✔False Apart from separate cabling, a ___ can be used to separate broadcast domains. - ✔✔VLAN A session is, - ✔✔an instance when a connection between two devices is created to transfer data An ARP whohas message is - ✔✔Broadcast Switches look at - ✔✔Dstination MAC addresses to forward frames All managed switches come from the factory with all of their configuration settings disabled. - ✔✔False How many channels are contained in a Multicast Flow? - ✔✔Up to 8 Collision domains are a practical concern on a switched network - ✔✔False Detailed understanding of the OSI model is required to design a Dante network - ✔✔False A network is a group of devices that connect and can interoperate together - ✔✔True Thins to consider when building a network from scratch - ✔✔Sizing links for worst case traffic loads In a [unicast] transaction bandwidth is only consumed on the [shortest] path between a receiver and a transmitter. - ✔✔ Diffserv QoS uses___tags - ✔✔DSCP When you assign a channel that is already being sent unicast to a multicast flow - ✔✔Existing unicast flow converts to multicast Traffic on the public internet is unicast - ✔✔True Dante automatically changes a unicast flow to a multicast flow when necessary - ✔✔False When a Dante enabled device is plugged into a network, how does the Dante Controller discover it? - ✔✔By listening to the device's announcement using mDNS Dante requirest strict priority queuing when QoS is used. - ✔✔True How much bandwidth does a unicast flow use - ✔✔6mbps Dante is best used on switches with at least___queues - ✔✔4 A transmit flow is a sequence of packets from multiple port addresses - ✔✔False The amount of bandwidth used by a multicast flow vary based on the number of channels - ✔✔True A--- segments a broadcast domain - ✔✔Router If 5 unicast channels are snet between two devices, how much bandwidth, and how many flows are being used? (sample rate 48khz/24-bit) - ✔✔12 mbps, and 2 flows Dante is an example of --- network service - ✔✔Real-time DSCP stands for - ✔✔Differentiated Services Code Point How do you find out how many transmit flows you are using? - ✔✔Tx tab in Dante controller A switch can be said to segment collision domains. - ✔✔True ARP tables are held in nodes - ✔✔True Joining VLANs requires a router - ✔✔True Sync traffic is the most time critical traffic in a Dant network and is tagged with DSCP___ - ✔✔56 Requirements of Dante are completely satisfied by a COTS infrastructure - ✔✔True To stop multicast traffic from flooding the network,___ can be used - ✔✔IGMP A VLAN can be assigned and IP address in order to allow a router to connect it to another VLAN - ✔✔True A multicast flow is created by a transmitter alone. - ✔✔True A unicast flow allows for the use of much lower latency settings than a multicast flow - ✔✔True What are some of the potential concerns IT administrators might have with multicast? - ✔✔Multicast potentially floods throughout the network Multicast might increase the traffic load on the network Key resource considerations for a successful Dante network deployments are: - ✔✔Enough Tx flows Enough Rx flows Enough Bandwidth QoS will not have a positive effect on constant bandwidth services - ✔✔True
