Question #2
A manufacturer wants to detect surface defects on parts moving along an assembly line using camera feeds. Which AI use case does this describe?
Correct answer: C
Explanation
Finding defects in images or video is a computer vision task, commonly deployed in manufacturing for visual inspection. The other options apply AI to text, tabular data, and audio rather than camera imagery.

Question #3
Which cooling method circulates liquid coolant through cold plates mounted directly on the GPUs and CPUs inside a server?
Correct answer: D
Explanation
Direct-to-chip liquid cooling pipes coolant to cold plates sitting on the hottest components, removing heat at the source. Immersion cooling submerges whole servers in fluid, and rear-door heat exchangers cool the air leaving the rack, so neither uses chip-mounted cold plates.

Question #6
A data center is preparing to host liquid-cooled GPU racks that each weigh well over a ton when fully populated. Which facility specification must be verified for the physical installation?
Correct answer: A
Explanation
Fully populated GPU racks are far heavier than typical enterprise racks, so the floor load rating must support the concentrated weight. Water temperature, utility voltage and carrier diversity are real facility concerns but do not address the weight of the racks.

Question #7
Which large labeled image dataset and its annual challenge helped drive the 2012 breakthrough in deep learning for image classification?
Correct answer: B
Explanation
ImageNet and its ILSVRC challenge supplied millions of labeled images, and the GPU-trained AlexNet won it in 2012. MNIST is a small handwritten digit set, LibriSpeech is audio, and Common Crawl is web text.

Question #8
A data center administrator needs to provision operating systems, deploy a workload manager and monitor a newly built GPU cluster from one interface. Which NVIDIA software should the administrator use?
Correct answer: B
Explanation
Base Command Manager handles cluster provisioning, workload manager deployment and health monitoring for DGX and other GPU clusters. Triton serves models, Nsight Systems profiles application performance, and NeMo is a framework for building generative AI models.

Question #9
Which NVIDIA networking platform is an Ethernet-based fabric built to accelerate AI workloads in the data center?
Correct answer: B
Explanation
Spectrum-X combines Spectrum Ethernet switches with BlueField-3 SuperNICs or DPUs to deliver an Ethernet fabric tuned for AI traffic. Quantum-2 is an InfiniBand platform, and the NVLink Switch connects GPUs over NVLink rather than Ethernet. DOCA is a software framework for DPUs, not a network fabric.

Question #10
Which network characteristic matters most for the east-west traffic between GPU servers during distributed training?
Correct answer: B
Explanation
Distributed training exchanges gradients and activations between nodes constantly, so the compute fabric needs high bandwidth and low latency. Internet bandwidth, perimeter inspection and addressing schemes do not determine how fast GPUs can synchronize.
