What is true about transparent memory page sharing?
A. It will not share more than 65% of a VMs memory.
B. It must be enabled on each host
C. It is enabled by default
D. It cannot be disabled.
Correct Answer: C
Explanation/Reference:
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. It is enabled by default.
