- B . SR-IOV offers comparable performance to non-visualized hardware.
- C . The VM must be attached to the PF to achieve highest performance.

Which of the following best describes the reason for CPU pinning?
- A . To ensure that a VM is assigned to high performance CPU cores.
- B . To ensure that a VM’s CPU cores area all allocated on the same NUMA node.
- C . To ensure that a VM is assigned to a compute node with adequate resources.
- D . To ensure that a VM is assigned a sufficient number of CPU cores.
Which of the following describes the benefit of using huge pages?
- A . Huge pages improves the performance of mapping virtual memory addresses to physical memory addresses.
- B . Huge pages improves the performance of decreasing the number of memory accesses involved in a page table walk.
- C . Huge pages improves the performance of page swapping by increasing the number of TLB cache hits.
- D . Huge pages improves the performance of page swapping by optimizing the loading of pages to main memory.
Which of the following describes the 2N model for VM redundancy?
