Which step can the engineer take to help improve the performance degradation of active applications?

Scenario: A Citrix Engineer is managing an existing XenDesktop and Workspace Environment Management (WEM) infrastructure. The engineer performed recent benchmarks on all the user applications. As a result of this investigation, the engineer determined that some applications are consuming excess memory even when they are idle and NOT actively being utilized by users. This results in performance degradation of active applications.

Which step can the engineer take to help improve the performance degradation of active applications?
A . Enable Working Set Optimization and set Idle State Limit to 10 minutes.
B . Enable Process I/O Priority and add Specified Processes.
C . Enable Working Set Optimization and set Idle Sample Time to 10 minutes.
D . Enable Working Set Optimization and Exclude Specified Processes.

Answer: C
