Which three tools are used for ongoing monitoring and maintenance of a voice and video environment? (Choose three.)
Answer(s): A,D,E
Need to identify CAC failures and call quality, active monitoring for loss, latency, and jitter, and flow-based analysis to look at APP flows
Refer to the exhibit. Traffic was equally balanced between Layer 3 links on core switches SW1 and SW2 before an introduction of the new video server in the network. This video server uses multicast to send video streams to hosts and now one of the links between core switches is over utilized. Which design solution solves this issue?
Answer(s): A
Refer to the exhibit. This enterprise customer wants to stream one-way video from their head office to eight branch offices using multicast. Their current service provider provides a Layer 3 VPN solution and manages the CE routers, but they do not currently support multicast. Which solution quickly allows this multicast traffic to go through while allowing for future scalability?
Answer(s): D
Which architecture does not require an explicit multicast signaling protocol, such as PIM or P2MP, to signal the multicast state hop-by-hop, but instead uses a link state protocol to advertise the multicast forwarding state?
Answer(s): B

Which two advantages of using DWDM over traditional optical networks are true? (Choose two.)
Answer(s): B,C
Two advantages of using Dense Wavelength Division Multiplexing (DWDM) over traditional optical networks are:Increased Capacity: DWDM allows for the multiplexing of multiple optical signals onto a single fiber, increasing the capacity of an optical network. This makes it possible to transmit a large amount of data over long distances without the need for additional physical fibers.Improved Reliability: DWDM provides a more resilient and reliable network by allowing for the transmission of multiple optical signals at different wavelengths over a single fiber. In the event of a fiber cut or other failure, the network can reroute traffic over a different wavelength, minimizing downtime and disruptions.
