Windows Server Administration Fundamentals — Question 178
On 32-bit x86 systems, the total virtual address space is of 4GB. By default, Windows allocates half of this address space to processes for their unique private storage and the other half for its own protected system memory utilization. Since 2GB is not enough virtual address space to map very large databases, which
Windows mechanism can be used by 32-bit applications to allocate up to 64GB of physical memory and to map views into its 2GB virtual address space?
Answer options
- A. Tracer
- B. Driver signing mechanism
- C. Address Windowing Extension
- D. Trap dispatching
Correct answer: C
Explanation
The correct answer is C, Address Windowing Extension, as it enables 32-bit applications to access more than the standard 2GB of virtual memory by mapping additional physical memory into their address space. Options A, B, and D do not relate to memory management and therefore cannot be used for this purpose.
