  A network administrator has reported poor network performance to an application server. After reviewing the logs, you determine that the server is using 100 percent of the available bandwidth on its network port. As shown in the exhibit, you configure a second link and a 2-member port-channel to an application server in an effort to increase performance. However, during testing, the network performance has not improved.

  What is a possible reason why there has been no increase in the performance?

  A. Application is using a single I/O flow
  B. File server needs to be configured with LACP
  C. Minimum links needs to be increased to "2"
  D. Port-channel needs load balancing enabled
  A. Application is using a single I/O flow
