최신 NVIDIA-Certified Professional NCP-AII 무료샘플문제 (Q98-Q103):

질문 # 98
You are validating the environment of an NVIDIA GPU-accelerated data center during post-deployment checks. Which one action is essential to confirm that power and cooling are sufficient for the stable operation of NVIDIA DGX H100 systems?

A. Use NVSM to disable unused PCIe devices to reduce overall system heat output.
B. Confirm the system fans are running at 100% under all workloads to prevent overheating.
C. Verify that each DGX system is connected to redundant, properly rated PDUs and that all power supplies are reporting nominal input.
D. Review the system BIOS to ensure GPU overclocking is enabled for maximum performance.

정답：C

설명：
Stable operation of high-density AI infrastructure like the DGX H100 requires strict adherence to power and thermal specifications. A single DGX H100 system can draw up to 10.2kW under peak load. Therefore, the most essential validation step is ensuring the electrical " infrastructure-to-server " handoff is healthy. This involves verifying that the system is connected to redundant PDUs (Power Distribution Units) capable of handling the amperage requirements without tripping breakers. Using NVSM (NVIDIA System Management), an administrator must check that all six power supplies (PSUs) are functional and receiving nominal input voltage (typically 200V-240V). If a PSU reports sub-optimal input or a " Loss of Redundancy,
" the system may throttle performance or shut down unexpectedly during a heavy training run. Fans running at 100% (Option A) at all times would actually indicate an inefficient or failed cooling policy, as fans should dynamically scale based on thermals. Overclocking (Option B) is not supported or recommended for enterprise DGX systems, as they are already factory-tuned for the highest stable performance.

질문 # 99
A financial services firm is deploying an AI model for fraud detection that requires rapid inference and data retrieval across multiple sites. Which feature should their storage system prioritize?

A. Tape backup systems.
B. Multi-protocol data access with low latency.
C. Low-cost HDD solutions.
D. High capacity with moderate speed.

정답：B

설명：
Fraud detection in financial services is a real-time AI workload. The system must ingest transaction data, retrieve historical customer profiles, and perform inference in milliseconds. This requires a storage architecture that supportsmulti-protocol access(such as S3 for ingestion and POSIX/NFS for inference engines) combined withlow latency. In these environments, storage latency directly impacts the "Time to Decision". An All-Flash storage tier is mandatory, as traditional HDD solutions (Option D) or moderate speed systems (Option B) introduce "Tail Latency" that can cause the fraud detection model to time out during peak transaction windows. Additionally, multi-site synchronization ensures that the latest model weights and historical data are available across different geographic data centers for high availability and localized inference.

질문 # 100
You are setting up a multi-node A1 cluster with NVIDIA GPUs and InfiniBand for inter-node communication. You need to ensure the InfiniBand network is functioning optimally for GPU-accelerated workloads. What steps would you take to validate the InfiniBand installation and performance?

A. Run 'ibstat' to check InfiniBand interface status, use 'ibping' and 'ibperf to test latency and bandwidth, and verify correct NCCL configuration (e.g., during a distributed training run.
B. Verify the InfiniBand drivers are installed and then run a standard TCP benchmark between the nodes.
C. Use 'nvidia-smi' to monitor InfiniBand traffic, and rely on CUDA-aware MPl for communication validation.
D. Configure a static IP address on the InfiniBand interfaces, and rely on the operating system's network diagnostics.
E. Run 'ibstat' to check InfiniBand interface status, use 'ping' to test connectivity, and rely on NCCL's internal checks during training.

정답：A

설명：
Sibstat' verifies interface status. 'ibping' and 'ibperf are InfiniBand-specific tools for latency and bandwidth testing. NCCL (NVIDIA Collective Communications Library) is critical for distributed training, and provides valuable diagnostic information. The other options are either incomplete or rely on tools not specific to InfiniBand.

질문 # 101
Consider the following simplified CUDA code snippet intended to perform a vector addition:
What are critical steps to validate that this code is correctly utilizing the GPU hardware and producing accurate results?

A. After the 'cudaMemcpy' from device to host, compare the 'c' array to a CPU-based vector addition result to verify correctness.
B. Run the code with 'cuda-memchecK to detect memory access errors or race conditions.
C. Ensure that 'blocksPerGrid' and 'threadsPerBlock' are appropriately chosen to maximize GPU occupancy, potentially using the NVIDIA CUDA Occupancy Calculator.
D. Use 'cudaDeviceSynchronize()' after launching the kernel to ensure the GPU computations are complete before copying data back to the host.
E. All of the above

정답：E

설명：
All options highlight important validation steps. Optimizing block/thread configuration maximizes GPU utilization. Verifying results against a CPU-based calculation ensures correctness. 'cudaDeviceSynchronize()' guarantees GPU computations are finished before data transfer. 'cuda-memcheck' detects memory errors. Failing to do any of these could lead to subtle errors or performance bottlenecks.

질문 # 102
A financial services firm is deploying an AI model for fraud detection that requires rapid inference and data retrieval across multiple sites. Which feature should their storage system prioritize?

A. Tape backup systems.
B. Multi-protocol data access with low latency.
C. Low-cost HDD solutions.
D. High capacity with moderate speed.

정답：B
