Which type of memory allows a virtual machine to start with a smaller amount of memory and increase it based on the workload of the virtual machine?

Which type of memory allows a virtual machine to start with a smaller amount of memory and increase it based on the workload of the virtual machine?

• A. Startup RAM
• B. Static Memory
• C. Virtual Memory
• D. Dynamic Memory

Answer: (D)

Dynamic memory is a virtualization feature that lets the hypervisor allocate memory to a VM based on its current needs. It lets the VM start with a smaller baseline (startup RAM) and then increase memory up to a planned maximum as workload demands rise. When the demand drops, the hypervisor can reclaim memory for other VMs. This approach optimizes memory use across the host. Startup RAM is just the initial amount assigned at boot and doesn’t automatically grow with workload. Static memory stays fixed and never scales. Virtual memory refers to the guest OS paging to disk to extend RAM, not to host-level dynamic allocation.
