Which two memory allocations can help troubleshoot a possible resource issue?

Choose two
  • A The user space, which has 708880 kB of physical memory that is not used by the system.
  • B The 98908 kB of memory that will never be used.
  • C The I/O cache, which has 641364 kB of memory allocated to it.
  • D The unused cache page, which is represented by the value indicated next to the Inactive heading.
Explanation

Cached reports the memory allocated to the system I/O cache, while Inactive identifies cache pages that have not been used recently and can be reclaimed if memory is needed. These values help distinguish cache use from memory actively consumed by processes. MemFree is unallocated physical RAM rather than user-space memory, and inactive pages are not memory that will never be used.
