What is the benefit of using Transparent Page Sharing in vSphere 6?

• A. It manages disk I/O more effectively
• B. It reduces the overall memory consumption across VMs
• C. It enhances CPU processing speed
• D. It increases network bandwidth

Answer: (B)

Using Transparent Page Sharing in vSphere 6 is primarily beneficial because it reduces the overall memory consumption across virtual machines (VMs). This technique works by identifying identical memory pages used by different VMs and consolidating them into a single memory page. When multiple VMs share identical data, this sharing allows the hypervisor to save memory since the duplicate pages can be represented in memory by a single copy. By minimizing the amount of memory needed for each VM, Transparent Page Sharing leads to more efficient utilization of the host's memory resources, enabling the hosting of more VMs on a single physical server while still maintaining performance levels. This is particularly advantageous in environments with many virtual machines running similar operating systems or applications, where duplicate memory usage is likely.
