Posted under Reverse Engineering

Answer: (d).To provide temporary storage for data that can be paged out to a pagefile if required Explanation:A pagefile-backed section object can be used for temporary storage of information and is usually created for the purpose of sharing data between two processes or between applications and the kernel. The section is created empty, and can be mapped to any address space (both in user memory and in kernel memory). Just like any other paged memory region, a pagefile-backed section can be paged out to a pagefile if required.
