What Windows NT component manages and allocates virtual or physical memory allocation to applications?

• A. Virtual Memory Manager (VMM)
• B. Virtualization
• C. Virtual Server
• D. Virus

Answer: (A)

The key idea is how an operating system handles memory allocation and address translation. In Windows NT, this is managed by the Virtual Memory Manager, or VMM. The VMM provides each process with its virtual address space, tracks which memory pages are in physical RAM versus on disk, and handles paging in and out as needed. It also coordinates allocation of physical memory frames and the use of the page file, translating virtual addresses to physical addresses as processes run. This specialized role is what makes the Virtual Memory Manager the correct choice. The other terms don’t fit this specific function: virtualization refers to creating virtual instances of hardware or systems, Virtual Server is a product related to virtualization, and a virus is malware.
