VCP-VVF IT Architectures Technologies Standards Practice Question
An infrastructure architect is designing a vSphere Foundation 9.0 cluster and needs to implement SR-IOV (Single Root I/O Virtualization) for high-throughput trading virtual machines. What is a key architectural trade-off when implementing SR-IOV virtual functions (VFs)?
Answer choices
Why each option matters
Answer the question above first, then reveal the full breakdown to understand why each option is right or wrong.
Correct answer & explanation
✓
Certain vSphere features such as live vMotion, fault tolerance, and snapshots may be limited or require specific hardware vendor support due to direct hardware binding.
SR-IOV bypasses the hypervisor network stack to deliver near-native hardware performance, but doing so means certain hypervisor-based features like vMotion, live snapshots, and DRS migration compatibility may be restricted or require specific hardware support.
Answer analysis
Option-by-option breakdown
For each option: why learners choose it and why it is or isn't the right answer here.
- ✗
SR-IOV requires all virtual machines to run exclusively on Linux kernel version 2.4.
Why it's wrong here
SR-IOV is supported across modern Windows and Linux guest operating systems with appropriate drivers.
- ✓
Certain vSphere features such as live vMotion, fault tolerance, and snapshots may be limited or require specific hardware vendor support due to direct hardware binding.
Why this is correct
Correct. Bypassing the hypervisor switch layer via SR-IOV restricts hypervisor-level mobility and management features for those virtual machines.
- ✗
SR-IOV doubles the CPU utilization of the ESXi host for packet encapsulation.
Why it's wrong here
SR-IOV actually reduces CPU utilization by offloading packet switching directly to the physical NIC.
- ✗
SR-IOV restricts virtual disk sizes to a maximum of 2 gigabytes.
Why it's wrong here
SR-IOV is a network/PCI passthrough technology and does not limit virtual disk capacities.
