QoS protects against too much bandwidth being used on a link by a collection of systems. Even if the overload happens over an extended period of time, packets are delivered in a timely manner, regardless of their QoS priority queue. - ANSWER- FALSE
Higher link speeds allow frames to be cleared quicker through an interface. - ANSWER-TRUE
A reply to ARP whohas message is - ANSWER-Unicast
Switches look at - ANSWER-Destination MAC addresses to forward frames
Based on what we know about different transmission methods, which type of traffic would we expect to find on the public internet? - ANSWER-Unicast 1 / 3

Key resource considerations for a successful Dante network should address network infrastructure and the Dante hardware
for the project. Designers should consider: (select all that apply)
- ANSWER--Enough bandwidth within the switch
-Enough Tx flows in Dante devices -Enough Rx flows in Dante devices -Enough bandwidth on trunk lines
A VLAN tag is part of the 802.1 header at layer .... - ANSWER- 2
It is highly recommended for the backplane of a switch to be able to accommodate full bandwidth use of all ports in both directions. - ANSWER-TRUE
In Dante Controller's Clock Status tab, you see reports of more than one clock master. The Dante Controller Log also shows devices reporting sync loss occasionally. What steps would you take to find the root cause of the problem? (SELECT ALL THAT APPLY) - ANSWER--Check switch configurations for any evidence of ACLs being configured. Check that all PTP 2 / 3

traffic can traverse the network in both directions to all switches.Specifically, UDP ports 319 and 320 on 224.0.1.129 -If IGMP snooping is enabled, test the system with no audio and IGMP snooping turned off. If this resolves the problem, you carefully examine the IGMP snooping configuration in each switch and ensure that they follow the guidelines.
32 multicast IP addresses map to one multicast MAC address. -
ANSWER-TRUE
You have a Dante system that seems to be functioning correctly most of the time. There are no external word clocks configured
and no preferred master configured. The problem: several
devices that report they are losing sync occasionally. What steps would you take to find the root cause of the problem? (Select all the apply) - ANSWER--You suspect that multicast traffic is not able to traverse the network in both directions (i.e. from master to all slaves, and from all slaves to the master). To check if this is the case you enable unicast delay requests on the slaves, then monitor the clock status histogram for evidence of disruption in PTP. When this resolves the problem you suspect that ACLs blocking multicast on UDP ports 319 and 320 in a direction from the slave to the master is to blame.-If IGMP Snooping is engaged, the switch CPU may be insufficient to meet the demand. Try turning IGMP snooping off,
