Which memory conservation technique allows the secure elimination of redundant copies of memory pages between virtual machines on the host?

A. Memory Balloon Driver B. VMkernel Swap C. RAM Overcommit D. Transparent Page Sharing D.Transparent Page Sharing

Explanation: Memory Provisioning Recommendations for VMware Infrastructure 3 Operational Best Practices page 7. Transparent Page Sharing is a process executed frequently by the VMkernel that scans physical memory to identify redundant virtual machine memory pages. When a match is found, the physical page is marked read-only. The VMkernel removes the duplicate page from physical RAM and the page table is adjusted to redirect the virtual machine’s virtual page back to the read-only page in physical RAM. This mechanism results in increasing memory that is shared among running virtual machines over time.
