SURE PASS!!
1.When should IGMP snooping (or other multicast management) be considered for
a Dante network? - ANSWER When the estimated multicast bandwidth may
approach a network port's saturation point, impacting performance.
2. A broadcast network transmission: - ANSWER transmits from one to everyone
on the network.
3. A network that carries multiple, possibly unrelated data types (like internet,
VoIP, Dante, etc.) is: - ANSWER called a converged network.
4. A multicast network transmission: - ANSWER can trim the distribution list with
IGMP snooping.
5. TCP: Good for general network
UDP: Good for LANs that are under your control - ANSWER TCP
UDP
6. Dante multicast can be managed with IGMP Snooping v2 or v3. - ANSWER
True
7. 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) -
ANSWER 1. When we have traffic a converged network, so there is something to
de-prioritize.
2. Only when using unmanaged switches.
8. Suppose a switch has 8 queues on it. Which queue number would typically have
the highest priority? - ANSWER 8
, 9. If you don't know the PIN to unlock a Dante device with "Device Lock"
engaged, can it be recovered? - ANSWER 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.
10. When commissioning or doing maintenance on a system with redundant
networks, which is a good practice? - ANSWER Connect one network at a time,
and verify that the devices are not set to switched mode.
11. If a switch has 10x 1Gbps ports, how much switching capacity would a switch
need to be considered "non-blocking"? - ANSWER 20gbps
12.What can Dante Firmware Updater (part of Dante Controller) do for us? (Select
all that apply.) - ANSWER 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.
13. When configuring IGMP Snooping, how many switches should be IGMP
Querier(s)? - ANSWER One - there can be only one.
14. If a multicast packet is sent on an unmanaged network, what will happen? -
ANSWER The multicast packet will propagate to every port on the network - it
will behave similarly to broadcast.
15. DSCP values range from 0-63. What is that used for in QoS? - ANSWER
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) - ANSWER 1. Switches without IGMP will forward Multicast to all
their ports.
2. Switches with IGMP will not forward unrequested Multicast.
