NEW QUESTION # 12
You are a data scientist working for a hotel booking website company. You use the Azure Machine Learning service to train a model that identifies fraudulent transactions.
You must deploy the model to an Azure Machine Learning online endpoint by using the Azure Machine Learning Python SDK v2. The deployed model must return real-time predictions of fraud based on transaction data input.
You need to create the script that is specified as the scoring_script parameter for the CodeConfiguration class used to deploy the model.
What should the entry script do?
Answer: E
Explanation:
The entry script (scoring script) for an Azure Machine Learning online endpoint must initialize the model when the container starts and process incoming transaction data to return real-time fraud predictions.
init() function: Runs once when the container is initialized. It must locate and load the trained model into memory (typically using a global variable) from the path specified by the AZUREML_MODEL_DIR environment variable.
run(data) function: Executes every time the endpoint receives a real-time HTTP request. It accepts the raw transaction payload, deserializes it, processes the features, passes them to the loaded model for prediction, and returns a JSON-serializable response.

NEW QUESTION # 13
Hotspot Question
You have an Azure Machine Learning workspace named Workspace1.
You plan to train an image classification model by using Automated ML in Workspace1.
You need to complete the provided Azure Machine Learning Python SDK v2 code to bring labeled image data as input for model training.
How should you complete the code? To answer, select the appropriate options in the answer area.
NOTE: Each correct selection is worth one point.
Answer:
Explanation:
Explanation:
Box 1: azure.ai.ml.constants
azure.ai.ml.constants is the official SDK v2 submodule where the AssetType enum resides.
Box 2: MLTABLE
AssetType.MLTABLE: Automated ML for Computer Vision tasks (such as image classification and object detection) specifically requires your input data and corresponding label annotations to be provided via an MLTable asset type. This structure points to a folder containing your dataset configurations and your .jsonl bounding box or classification files.

NEW QUESTION # 14
You must ensure full reproducibility of experiments including dataset, code, and environment across multiple runs and workspaces. Which combination of practices is MOST appropriate?
Answer: B
Explanation:
Reproducibility requires versioning all components: code, datasets, and environments. Missing any of these elements prevents exact replication of experiments. For example, the same code with different data or dependencies can produce different results, making debugging and auditing difficult.
NEW QUESTION # 15
You manage a Retrieval-Augmented Generation (RAG) system that uses Azure AI Search to retrieve documents from an indexed knowledge base.
The system must support the following retrieval requirements:
Queries that include exact policy identifiers must return matching documents even when semantic similarity is low.
Natural-language questions must prioritize semantically relevant documents even when keywords are not an exact match.
You need to configure the retrieval approach to meet the requirements.
How should you configure the retrieval behavior for each requirement? To answer, select the appropriate options in the answer area . NOTE: Each correct selection is worth one point.
Answer:
Explanation:
Explanation:
Different query types require fundamentally different retrieval algorithms. For queries that include exact policy identifiers, keyword or BM25 search is the correct choice because BM25 scores documents based on term frequency and inverse document frequency - an exact match on a specific policy identifier such as POL-
2024-HR-042 scores very highly regardless of semantic context. This is the right approach when semantic similarity is low but exact term matching is critical. For natural-language questions where keywords may not be an exact match, semantic or vector search is the correct choice because vector embeddings capture meaning rather than exact tokens, finding relevant documents even when the user ' s vocabulary differs from the document ' s terminology. Azure AI Search supports both modes through its hybrid search capability, and the correct configuration maps each query type to its optimal retrieval algorithm.

NEW QUESTION # 16
A team is deploying machine learning models to a production inference endpoint in Azure Machine Learning.
The team requires a safe way to validate a new model version without disrupting existing users.
You need to recommend a deployment strategy for controlled testing of a new model version.
What should you configure?
Answer: B
Explanation:
A managed online endpoint can host multiple named deployments simultaneously, and you control what percentage of incoming traffic each deployment receives. With traffic splitting, you route a small percentage of live traffic to the new deployment while the majority continues to the proven existing model. You then monitor error rates, latency, and output quality for both deployments in real time under genuine production load. If the new model underperforms, you instantly route traffic back - no downtime, no user disruption. If it outperforms, you gradually increase its traffic share to 100%. Updating the registry version (option B) does not affect running deployments. A staging endpoint (option C) does not validate under real production load.
An evaluation script (option D) is a pre-deployment step. Traffic splitting is the blue/green and canary deployment pattern that Microsoft recommends for safe production rollouts.
