To ensure that a VM is assigned to high performance CPU cores. ✘ To ensure that a VM's CPU cores area all allocated on the same NUMA node. ✘ To ensure that a VM is assigned to a compute node with adequate resources. ✘ To ensure that a VM is assigned a sufficient number of CPU cores. ✔

Huge pages improves the performance of mapping virtual memory addresses to physical memory addresses. ✘ Huge pages improves the performance of decreasing the number of memory accesses involved in a page table walk. ✘ Huge pages improves the performance of swapping by increasing the number of TLB cache hits. ✘ Huge pages improves the performance of swapping by optimizing the loading of pages to main memory. ✔

There is one active VM and one standby VM that takes over if the active VM fails. ✘ Thera are N active VMs and a pool of standby VMs that can take over if one or more active VMs fail. ✘ There are N active VMs, each one paired with a standby VM that takes over if its active VM fails. ✘ There are 2N active VMs deployed to support a service that needs N active VMs, with extra capacity in case one or more VMs fail. ✔
