NEW QUESTION # 55
You are tasked with deploying a machine learning model into a production environment for real-time fraud detection in financial transactions. The model needs to continuously learn from new data and adapt to emerging patterns of fraudulent behavior. Which of the following approaches should you implement to ensure the model's accuracy and relevance over time?
Answer: B
Explanation:
Continuously retraining the model using a streaming data pipeline (C) ensures accuracy and relevance for real- time fraud detection. Financial fraud patterns evolve rapidly, requiring the model to adapt to new data incrementally. A streaming pipeline (e.g., using NVIDIA RAPIDS with Apache Kafka) processes incoming transactions in real time, updating the model via online learning or frequent retraining on GPU clusters. This maintains performance without downtime, critical for production environments.
* Static dataset retraining(A) lags behind emerging patterns, reducing relevance.
* Retrain only on accuracy drop(B) is reactive, risking missed fraud during degradation.
* Parallel rule-based systems(D) add redundancy but don't improve model adaptability.
NVIDIA's AI deployment strategies support continuous learning pipelines (C).
NEW QUESTION # 56
Your AI team is deploying a multi-stage pipeline in a Kubernetes-managed GPU cluster, where some jobs are dependent on the completion of others. What is the most efficient way to ensure that these job dependencies are respected during scheduling and execution?
Answer: A
Explanation:
Using Kubernetes Jobs with Directed Acyclic Graph (DAG) scheduling is the most efficient way to ensure job dependencies are respected in a multi-stage pipeline on a GPU cluster. Kubernetes Jobs allow you to define tasks that run to completion, and integrating a DAG workflow (e.g., via tools like Argo Workflows or Kubeflow Pipelines) enables you to specify dependencies explicitly. This ensures that dependent jobs only start after their prerequisites finish, automating the process and optimizing resource use on NVIDIA GPUs.
Increasing job priority (A) affects scheduling order but does not enforce dependencies. Deploying all jobs concurrently with pod anti-affinity (C) prevents resource contention but ignores execution order. Manual monitoring (D) is inefficient and error-prone. NVIDIA's "DeepOps" and "AI Infrastructure and Operations Fundamentals" recommend DAG-based scheduling for dependency management in Kubernetes GPU clusters.
NEW QUESTION # 57
Your organization has deployed a large-scale AI data center with multiple GPUs running complex deep learning workloads. You've noticed fluctuating performance and increasing energy consumption across several nodes. You need to optimize the data center's operation and improve energy efficiency while ensuring high performance. Which of the following actions should you prioritize to achieve optimized AI data center management and maintain efficient energyconsumption?
Answer: C
Explanation:
Implementing GPU workload scheduling based on real-time performance metrics is the priority action to optimize AI data center management and improve energy efficiency while maintaining performance. Using tools like NVIDIA DCGM, this approach monitors metrics (e.g., power usage, utilization) and schedules workloads to balance load, reduce idle time, and leverage power-saving features (e.g., GPU Boost). This aligns with NVIDIA's "AI Infrastructure and Operations Fundamentals" for energy-efficient GPU management without sacrificing throughput.
Disabling power management (A) increases consumption unnecessarily. Adding GPUs (C) raises costs without addressing efficiency. More cooling (D) mitigates symptoms, not root causes. NVIDIA prioritizes dynamic scheduling for optimization.

What is the benefit of NGC?
Answer: B
Explanation:
NGC (NVIDIA GPU Cloud) provides a curated set of GPU-optimized software, including pre- trained AI models, containers, and SDKs, which accelerates deployment and ensures compatibility with NVIDIA GPUs.
NEW QUESTION # 59
Which function is unique to workload managers in AI infrastructure (vs. general OS schedulers)?
Answer: A
Explanation:
Workload managers in AI infrastructure provide fine-grained control over allocating GPUs, CPUs, memory, and interconnect resources across distributed jobs, which goes beyond the basic process scheduling performed by general operating systems.
