A) Generative Pre-trainingB) Standard InferenceC) Retrieval-Augmented Generation (RAG)D) Supervised Image ClassificationE) Unsupervised ClusteringF) Reinforcement LearningCorrect Answer: COverall Explanation: Retrieval-Augmented Generation combines large language models with external knowledge retrieval to improve accuracy and context,A is incorrect because pre-training involves training a model from scratch on large datasets, not querying external databases during generation,B is incorrect because standard inference applies a trained model to new data without the specific retrieval step,C is correct because Retrieval-Augmented Generation specifically retrieves external data to ground the generated output,D is incorrect because supervised classification assigns labels to data based on labeled training,E is incorrect because unsupervised clustering groups unlabelled data,F is incorrect because reinforcement learning trains models via reward feedback,Question 2: When configuring high-performance networks for AI workloads on Cisco infrastructure, which mechanism ensures lossless transport by pausing traffic on a per-priority basis? A) Explicit Congestion Notification (ECN)B) Priority Flow Control (PFC)C) RDMA over Converged Ethernet (RoCE)D) Enhanced Transmission Selection (ETS)E) Quality of Service PolicingF) Virtual PortChannel (vPC)Correct Answer: BOverall Explanation: Priority Flow Control is a key technology in data center bridging that provides lossless delivery for specific classes of service by pausing traffic,A is incorrect because ECN marks packets to signal congestion rather than pausing traffic directly,B is correct because PFC sends pause frames for specific priorities to prevent dropped packets, ensuring lossless transport,C is incorrect because RoCE is the protocol utilizing the lossless network, not the pause mechanism itself,D is incorrect because ETS manages bandwidth allocation across different traffic classes,E is incorrect because QoS policing limits bandwidth rather than guaranteeing lossless transport,F is incorrect because vPC provides link redundancy and load balancing,Question 3: Which Cisco tool provides centralized management, monitoring, and telemetry for troubleshooting an AI data-center infrastructure?
