An administrator of a peer-to-peer server application reports that the maximum bandwidth that his application receives is 90 Mb/s. You have an 8-port,100-Mb/s EtherChannel bundle on the switching infrastructure between the two servers, resulting in a bidirectional throughput of more than what is recorded. Which two solutions would allow for more bandwidth for the application?()
Which one of the following potential issues is eliminated by using split horizon?()
Multicast is being deployed in the network, and only ip pim sparse-dense mode has been configured on all interfaces in the network to support a new video streaming application. No other multicast configuration was applied anywhere in the network. Since enabling multicast, the network monitoring tools show periodic spikes in link utilization throughout the network, even in areas where the video application is not being used. What could be a possible cause?()
In GLBP, which router will answer on client ARP requests?()
When a BGP router is not capable of understanding 4-byte AS numbers, it will see 4-byte AS numbers as a special, reserved, 2-byte AS number in the AS path. Which 2-byte AS number is this reserved one?()
