Cable subscribers may expect up to 27 Mbps of bandwidth on the upload path. Mar 17 R3 has the following configuration: R3 show running-config.
Full duplex allows both ends to transmit and receive simultaneously. Full duplex increases the effective bandwidth. What can be concluded about network This network has been learned from an internal router within the same area. This network should be used to forward traffic toward external networks. Configuring the EtherChannel interface provides consistency in the configuration of the physical links. Load balancing occurs between links configured as different EtherChannels.
Spanning Tree Protocol views the physical links in an EtherChannel as one logical connection. What are two results of issuing the displayed commands on S1, S2, and S3? S1 will automatically adjust the priority to be the highest. S2 can become root bridge if S3 fails. S3 can be elected as a secondary bridge. S2 can become root bridge if S1 fails. When users access high bandwidth services such as streaming video, the wireless network performance is poor. Why might this solution improve the wireless network performance for that type of service? The 5 GHz band has more channels and is less crowded than the 2. Requiring the users to switch to the 5 GHz band for streaming media is inconvenient and will result in fewer users accessing these services. The 5 GHz band has a greater range and is therefore likely to be interference-free.
A network administrator is configuring Frame Relay subinterfaces on R1. A distance vector routing protocol has also been configured. Data is routing successfully from R1 to networks that are connected to R2, R3, and R4, but routing updates between R2 and R3 are failing. What is the possible cause of this failure? Split horizon is preventing successful routing table updates on the multipoint link. Subinterfaces cannot be used on multipoint Frame Relay links.
Two DLCI identifiers cannot be configured on one subinterface. A network administrator issues the show frame-relay map command to troubleshoot the Frame Relay connection problem. Based on the output, what is the possible cause of the problem? Inverse ARP is providing false information to the R1 router. Use an acronym.
