124. Frage
A machine learning model is deployed to production in Azure Machine Learning and is actively serving predictions for a business application. The model was trained by using a historical dataset that represented expected input patterns at the time of deployment.
The team working on the model must ensure the following:
Changes in input data distribution are detected.
Appropriate actions are triggered when predefined thresholds are exceeded.
You need to configure monitoring to meet the requirements.
Which configuration should you use for each requirement? To answer, select the appropriate options in the answer area. NOTE: Each correct selection is worth one point.
Antwort:
Begründung:
Explanation:
Azure Machine Learning ' s data drift monitor solves the first requirement: it continuously compares the statistical distribution of live inference input features against the baseline training data distribution, flagging when significant drift occurs. For the second requirement of triggering appropriate actions when thresholds are exceeded, Azure Monitor alert rules are configured on the drift metrics. When the drift coefficient exceeds a defined threshold, Azure Monitor fires an alert that can invoke Logic Apps, send emails, trigger an Azure ML retraining pipeline, or post to Teams. This two-layer approach - ML-specific drift detection backed by Azure Monitor alerting - is the Microsoft-recommended pattern for production model monitoring. The data drift monitor handles detection, while Azure Monitor handles the operational response, keeping the two concerns cleanly separated.

126. Frage
A team deploys a classification model to production and scores incoming customer data daily.
After several weeks, business stakeholders report unexpected changes in prediction behavior, even though the endpoint remains healthy.
You need to determine whether data drift is occurring and if it is, identify the appropriate actions.
Which action should you perform for each observed signal? To answer, move the appropriate actions to the correct observed signals. You may use each action once, more than once, or not at all. You may need to move the split bar between panes or scroll to view content.
NOTE: Each correct selection is worth one point.
Antwort:
Begründung:
Explanation:
Input feature distributions differ from training data: Analyze dataset drift metrics Model accuracy drops without code changes: Review prediction and ground truth trends Endpoint latency increases under load: Investigate scaling and infrastructure metrics When input feature distributions differ from training data , the correct action is to analyze dataset drift metrics . Azure Machine Learning model monitoring detects data drift by comparing the statistical distributions of production model inputs against reference data, commonly the original training dataset.
Supported measures include Population Stability Index, Jensen-Shannon distance, normalized Wasserstein distance, and statistical tests such as Kolmogorov-Smirnov.
When model accuracy drops without code changes , the next investigation should focus on prediction and ground-truth trends . Azure Machine Learning model-performance monitoring compares production predictions with collected actual outcomes and can calculate classification metrics such as accuracy, precision, and recall. A declining score without deployment changes may indicate concept drift, prediction drift, or changing relationships between input features and target outcomes.
When endpoint latency increases under load , the issue is operational rather than primarily statistical. The team should investigate scaling and infrastructure metrics , including request latency, requests per minute, CPU/memory utilization, throttling, and replica capacity. Microsoft recommends using endpoint metrics to determine whether compute must scale up or out.
Rebuild the inference container image is not indicated by any of the observed signals.

A team is developing a Retrieval-Augmented Generation (RAG) system.
The team requires improvements to the system ' s retrieval quality to ensure accurate, grounded responses.
You need to assess RAG performance before you can suggest an improvement strategy.
Which four actions should you perform in sequence? To answer, move the appropriate actions from the list of actions to the answer area and arrange them in the correct order.
Antwort:
Begründung:
Explanation:
Correct sequence:
* Collect retrieval logs.
* Run RAG evaluators.
* Adjust chunking strategy.
* Re-index documents.
The process should begin by collecting retrieval logs . Retrieval diagnostics provide the evidence needed to understand which queries were issued, which document chunks were returned, and whether relevant content is being surfaced. Without retrieval telemetry, optimization becomes speculative rather than measurable.
Next, run RAG evaluators . Microsoft Foundry provides retrieval-oriented evaluators that assess how relevant retrieved context is to a query. The Retrieval evaluator measures contextual relevance without requiring ground truth, while the Document Retrieval evaluator can calculate metrics such as Fidelity and NDCG when labeled retrieval ground truth exists. These measurements help establish the retrieval-quality baseline before modifications are made.
After identifying retrieval deficiencies, adjust the chunking strategy . Microsoft specifically recommends reviewing chunk size and chunking methodology when retrieval returns irrelevant or incomplete passages.
Chunks that are too small can lose context, while oversized chunks can introduce irrelevant material and reduce retrieval precision.
Finally, re-index the documents so the revised chunking configuration is reflected in the searchable corpus.
Changing temperature or regenerating the prompt template primarily affects generation behavior rather than correcting the underlying retrieval pipeline.

Note: This question is part of a series of questions that present the same scenario. Each question in the series contains a unique solution that might meet the stated goals. Some question sets might have more than one correct solution, while others might not have a correct solution.
After you answer a question in this section, you will NOT be able to return to it. As a result, these questions will not appear on the review screen.
You manage an Azure Machine Learning workspace. The Python script named script.py reads an argument named training_data.
The training_data argument specifies the path to the training data in a file named dataset 1. csv.
You plan to run the script.py Python script as a command job that trains a machine learning model.
You need to provide the command to pass the path for the dataset as a parameter value when you submit the script as a training job.
Solution: python script.py --trainingdata ${{inputs.training_data}}
Does the solution meet the goal?
Antwort: A
Begründung:
According to Microsoft ' s Azure Machine Learning SDK v2 documentation on command jobs, input arguments in the command string must exactly match the argument names defined in the Python script ' s argparse configuration. The script reads an argument named training_data with an underscore, but the proposed command passes --trainingdata without the underscore. Python ' s argparse treats these as completely different argument names, so the script would receive None for its --training_data argument, causing a runtime error. The placeholder syntax for referencing the input in the command string is correct, which is a point in this solution ' s favor. However, the argument name mismatch alone is sufficient to make this solution fail. The corrected command would use --training_data exactly matching the argument name defined in the script.
