Cisco 3 - Switch Perrine. J Page 57/3/2016 Chapter 3 Why would it be necessary to configure the bandwidth setting on an EIGRP interface rather than leaving it at the default setting? (Choose two.) 1.A suboptimal route may be chosen as the best path to a destination if the bandwidth setting is higher than the actual bandwidth of the link. 2.The network may be unable to converge if the bandwidth setting does not match the actual bandwidth of the link. 3.Routing updates might arrive too fast for the interface to handle and be discarded because of buffer overflow. 4.The configured bandwidth must match the actual speed of the link so the link will operate properly. 5.Setting the bandwidth to a higher rate will optimize the effective throughput of the link.
