Your network contains an ISA Server 2006 computer named ISA1. ISA1 is configured to provide forward Web caching for users on the Internal network. During periods of peak usage, users report that it takes longer than usual for Web pages to appear. You suspect that insufficient memory is the source of the slow performance of ISA1. You need to verify whether insufficient memory is the source of the slow performance. Which two System Monitor performance counters should you add? (Each correct answer presents part of the solution.
Choose two.)

A.
MemoryPages/sec

B.
Process(W3Prefch)Pool Nonpaged Bytes

C.
ISA Server CacheMemory Usage Ratio Percent (%)

D.
Physical DiskAvg. Disk Queue Length

E.
