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？（）A、change the EtherChannel default hashing algorithm from XOR to use source port Layer 4 port load balancing to better load balance the trafficB、change the EtherChannel default hashing algorithm from XOR to use destination Layer 4 port load balancing to better load balance the trafficC、have the application recoded to use multiple connections instead of a single connection so EtherChannel can better load balance the trafficD、upgrade the CPU and memory of the compute devices so they can better process trafficE、upgrade the EtherChannel bundle to a single gigabit link because EtherChannel is not well suited for single-connection traffic
