A network administrator has configured a new 100Mbs WAN circuit, but speed testing shows poor performance when downloading large files. The download initially reaches close to 100Mbps but begins to drop and show spikes in the downloads speeds over time. The administrator checks the router interface and sees the following: - Router01#show interface eth 1/1 - GigabitEthernet 1/1 is up, line is up - Hardware is GigabitEthernet, address is 000A.00BB.CC11 - Configured speed auto, actual 1Gbit, configured duplex fdx, actual fdx Member of L2 VLAN 1, port is untagged, port state is forwarding Which of the following is MOST likely to resolve the issue?
