Question 9
UnclassifiedHow do you verify GPU PCIe generation and link width?
Correct answer: C
Explanation
GPU PCIe generation and link width are shown in both the device’s hardware details and the PCIe link status. The answer is right because either source can report the same fields: generation as the PCIe version and width as the lane count, so "Both A and B provide this information."
Why each option is right or wrong
A. nvidia-smi -q -d PCIE
B. lspci -vvv -d 10de:
C. Both A and B provide this information
GPU PCIe generation and link width are exposed in two places: the device’s hardware properties and the PCIe link status readout. In practice, the generation is reported as the PCIe version (for example, Gen 3/4/5) and the width as the active lane count (for example, x8 or x16), so either source can confirm both fields. The answer is therefore the one that recognizes both A and B as valid verification points.
