NCP-GENL Exam Preparation Material | Generative AI LLMs

Prepare for the NCP-GENL with reliable study materials, practice questions, and key exam insights.

Prepare for the NCP-GENL Generative AI LLMs exam with CertQueen's independently developed study resources. Review important concepts, practice scenario-based questions, and use clear explanations to identify areas that require further study.

Question#1

Optimizing all-reduce operations for a cluster with 32 GPUs across 4 nodes (8 GPUs/node with NVLink).
Which TWO techniques provide the greatest performance improvement? Pick the 2 correct responses below

A. Increase the InfiniBand MTU size from default 1024 to 4096 bytes
B. Enable GPU Direct RDMA for direct GPU-to-GPU communication across nodes
C. Use gradient compression techniques to reduce communication volume by 50-90%
D. Implement hierarchical all-reduce: intra-node via NVLink, then inter-node via InfiniBand
E. Schedule all-reduce operations on dedicated CUDA streams for overlap

Question#2

What is the primary reason for applying activation quantization during inference?

A. To remove the need for normalization layers in transformer blocks
B. To simplify the model architecture for embedded deployments
C. To reduce activation memory usage and improve computational speed
D. To eliminate the need for key-value caching in decoder models

Question#3

You’re optimizing inference for a production system handling long documents (32K tokens) using both encoder-decoder (T5-XXL, 11B params) and decoder-only (Llama-2-70B) models. Memory profiling shows critical bottlenecks. Given: T5 uses full cross-attention, Llama-2 uses GQA with 8 KV heads, both run with FP16. The system must maintain <100ms time-to-first-token (TTFT) and support 16 concurrent requests.
Which architectural insight most accurately guides the optimization strategy?





A. T5’s memory scales as O(nxm) where n=input length, m=output length, due to cross-attention, while Llama-2 scales as O(m’xhkv/hq) with GQA, making T5 more memory-efficient for long inputs with short outputs
B. Llama-2's KV cache requires (2xlayerfehkvxdheadxseqlenxbatch) bytes, approximately 28GB for 32K context, while T5’s encoder output cache is constant after encoding, requiring only (layers x hiddendim x input_len x batch) bytes
C. Both architectures benefit equally from PagedAttention since memory fragmentation is the primary bottleneck, not the absolute memory requirement differences between architectures

Question#4

Which method supports the creation of a language model that is both lightweight and capable of maintaining strong performance across tasks?

A. Performing distributed hyperparameter tuning to explore a wide range of model settings
B. Selecting advanced sampling techniques to diversify the generated outputs
C. Utilizing knowledge distillation to train a smaller model that learns from a teacher model
D. Using sliding-window attention mechanisms for handling long input sequences

Question#5

A fintech company's investment advice LLM occasionally provides responses that could be construed as guaranteed returns, despite training to avoid this.
Examples:
• User: "Will NVIDIA stock go up?"
• Model: “Based on current trends, NVIDIA will definitely see gains'
They need guardrails that:
• Prevent guarantee-like language
• Maintain helpful analysis
• Work across multiple languages
• Have <50ms latency overhead
Which guardrail implementation would best meet these requirements?

A. Deploy a lightweight classifier trained on compliant/non-compliant financial advice examples to score responses
B. Use a semantic similarity model comparing outputs against a curated set of prohibited guarantee templates
C. Implement a regex-based filter checking for prohibited phrases like “will definitely," "guaranteed," "certain to"
D. Apply template-based response generation that inserts disclaimer language when investment topics are detected
