Dante Certification Final Exam Questions and

Answers 2024 Update

STUDY GUIDE 1 - Correct Answer

1. On a Dante network, there must be a different clock leader for each sample rate on the network. - Correct Answer False. One Clock Master will provide synchronization to all Dante devices, regardless of their individual sample-rates or frame rates..
2. An audio subscription (connection) can be established between two Dante interfaces operating at different bit depths. - Correct Answer True. Like most digital audio devices, Dante devices will usually be able to add missing bits or truncate extraneous bits to match the expected internal operation.
3. The sample rate of an audio system dictates: - Correct Answer the audio resolution in time. According to the Nyquist Theorem, the sample rate must be at least twice the highest audio frequency to be captured. The bit depth of an audio system
4. dictates: - Correct Answer the resolution of the audio signal's amplitude. A greater bit depth increases dynamic range.
5. A Dante audio subscription (connection) can be established between two Dante interfaces operating at different audio sample rates - Correct Answer False. Each Dante interface can only operate at one sample rate at a time. If a sample rate converter is employed, it will sit behind the Dante network port.
6. Dante audio is sent: - Correct Answer Uncompressed, bit-perfect.
7. What audio sample rates are supported by Dante? - Correct Answer Dante supports most common sample rates from 44.1kHz to 192kHz.
8. If we increase the sample rate of a device from 48KHz to 96KHz, what is the impact to the network? - Correct Answer A 96kHz subscription will require (roughly) twice as much bandwidth as a 48kHz subscription.
9. Roughly how many channels of 24-bit, 48kHz audio can be carried on a 1 Gbps connection? - Correct Answer 512x

10. A 1Gbps network switch can manage more Dante channels than a single 1Gbps link can. - Correct Answer True. A non-blocking network switch will be able to handle the total of all ports capacity at all times. STUDY GUIDE 2 - Correct Answer Dante AV can support multiple codecs. However, the initial products
11. will transport video in what format? - Correct Answer Compressed using a visually lossless JPEG2000 codec. The JPEG 2000 codec initially included in the Dante AV module is used in 65% of digital cinema rooms today. It is visually lossless,
12. supporting both video and computer graphics (like spreadsheets and slide presentations). - Correct Answer True. The JPEG2000 offers sharp quality and intense colour definition with a visual accuracy adopted by most professional uses.
13. Dante AV devices sends and receives audio uncompressed so it is completely compatible with Dante audio devices. - Correct Answer True. As audio and video are transported separately as independent essences, it is possible for a Dante AV device to send its audio channels to a Dante Audio device and vice- versa.
14. Interlaced video draws all the odd lines, then all the even lines. This creates two "fields" for each frame. - Correct Answer TRUE. The interlaced signal contains two fields of a video frame captured consecutively. This enhances motion perception to the viewer, and reduces flicker. Dante AV devices have a scaler in it.
15. What does the scaler affect? - Correct Answer The scaler can adapt screen resolution. (i.e. - it can scale a 4K source to 1080p for display)
16. Which answer best describes the JPEG2000 encoding process? - Correct Answer There is a "visually lossless" impact on the first encoding, but JPEG 2000 can decode and encode over and over with no further loss. In Dante AV, with the JPEG2000 codec and a 1 Gbps connection, what resolution and frame rates are
17. currently supported? - Correct Answer Up to 4K (4096 x 2160) at 60fps The JPEG 2000 codec commonly used in Dante AV processes video frames in groups. If a packet is corrupted, the picture will

automatically recover when the current group of frames ends and the next keyframe arrives. It could be

18. several frames. - Correct Answer False. The JPEG2000 codec is the best example of intraframe encoding, applying a compression algorithm to each frame captured individually, not built up from multiple frames, so they can be compressed and transmitted out quickly to reduce latency.
19. On a Dante network, a single clock leader is established to manage all audio sample rates and video frame rates. - Correct Answer True. A single Clock Leader on the network is able to keep all followers synchronised, regardless of their sample-rates or frame-rates. What factors significantly affect the overall bandwidth demands of a
20. compressed video flow? (Select all that apply.) - Correct Answer -The video frame resolution (i.e. - 1080p vs 4K) -The chroma sampling (i.e. - 4:4:4 vs 4:2:0) -The frame rate (ie 24fps vs 60fps) STUDY GUIDE 3 - Correct Answer
21. When using category cable, what type is recommended? - Correct Answer CAT5e or better is recommended.
22. What IP addressing methods are available for Dante devices? (Select all that apply.) - Correct Answer -Static IP Addressing -DHCP Dynamic Host Configuration Protocol -Link Local
23. Which IP Range is not designated for use on a local network? - Correct Answer 8.8..
24. Neutrik etherCON ports must be populated by Neutrik etherCON cables. - Correct Answer False. The Neutrik etherCON port provides an RJ45 at the center and thus it does accept standard Ethernet cables.
25. Which statements are true about Dante and switches to connect them? (Select two.) - Correct Answer -Some Dante devices can daisy-chain, allowing small systems to run without the need for an external network switch. -Unmanaged switches may be fine for small systems.
26. When choosing a network switch, what minimum speed is suggested? - Correct Answer 1 Gbit switch

27. Which statement is true about PoE: - Correct Answer Each PoE device will draw only the power it needs. Manufacturers typically list the power draw of their PoE devices - you can add the total plus a cushion (perhaps 20%). Many Dante products will provide a Dante port and "Manufacturer Control" port that is totally separate. The separate port might be used to remote control a mixer, program a DSP, or monitor an amplifier.
28. How do you set the IP address for the manufacturer's control port? - Correct Answer Read the instruction manual for the product. Setting the manufacturer's control port is unrelated to Dante, and thus it can be different for each product line.
29. Which of these are network topology methods were discussed for connecting Dante and Dante AV devices? (Select two.) - Correct Answer -daisy chain -star
30. Tell me about Energy Efficient Ethernet (EEE). - Correct Answer It should be disabled on Dante network (or any real-time network). While it can save a bit of energy, it is known to cause data interruptions that can skew clocking (synchronization) and cause audio/video dropouts. Many Dante products will provide a Dante port and "Manufacturer Control" port that is totally separate. The separate port might be used to remote control a mixer, program a DSP, or monitor an amplifier.
31. When this manufacturer control port is provided, it is sometimes exposed on its own network connection, sometimes it is merged with an internal network switch so it appears through the Dante Primary port. - Correct Answer True
32. What type of network connections should be used to transport Dante traffic? (Select all that apply.) - Correct Answer -CAT5e or better for 1Gbit links up to 100m in length. -Fiber optic connections - common for 1Gbit or faster in link lengths of 300m-500m. These can go for kilometers. -WiFi can only be used for control data. No audio or video media will be transported on WiFi.
33. If a device has an IP address of 192.168.15.12 and a subnet mask of 255.255.255.0, which IP address would be within its subnet? - Correct Answer 192.168.15.
34. If a device has obtained an IP address using Link Local, which IP configuration would be within its subnet? - Correct Answer IP Address: 169.254.189. Subnet Mask: 255.255.0.

41. Dante AV sends audio and video in the same stream (essence). - Correct Answer FALSE
42. What are Dante Application Library (DAL) and Dante Embedded Platform (DEP)? - Correct Answer Ways to add Dante to products without requiring specific chipsets from Audinate. Products using these may require a separate activation process to enable Dante functiona
43. Dante is: - Correct Answer A complete Audio-Video over IP (AVoIP) solution, going beyond the transport to encompass a consistent hardware/firmware/software solution for reliability, scalability and t savings.
44. A Dante device's name and channel labels are: - Correct Answer user definable and will be remembered by the device.

45. The same Dante audio and/or video channels can be sent to multiple receivers on the network at the same time. (In other words, the signal can be split to multiple dest - Correct Answer TRUE
46. The default Dante latency of 1 msec
47. is: - Correct Answer very low and suitable for the majority of applications. Dante transmitters are called
48. "sources". Dante receivers are called: - Correct Answer destinations or sinks. Dante devices remember their settings and automatically restore on power loss or manual restart. Dante Controller does not need to be present on the network for this to
49. happen. - Correct Answer TRUE In Dante Controller, a green
50. checkmark indicates: - Correct Answer Subscription is successful.
51. What is latency (generically)? - Correct Answer is the amount of time required for a process to occur - we measure it from input to output of a process.
