NEW QUESTION # 113
Drag and Drop Question
You complete the fine-tuning of a generative model in Microsoft Foundry. The fine-tuned model now appears as a new model variant in your development environment.
The deployment process must ensure that proper validation and control is maintained.
You need to promote the fine-tuned model from development to production.
Which three 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.
Answer:
Explanation:
NEW QUESTION # 114
You create a binary classification model. You use the Fairlearn package to assess model fairness.
You must eliminate the need to retrain the model.
You need to implement the Fairlearn package.
Which algorithm should you use?
Answer: A
Explanation:
The best algorithm to implement within the Fairlearn package for a binary classification model without retraining is the ThresholdOptimizer.
Why ThresholdOptimizer?
This algorithm is a post-processing technique specifically designed to mitigate unfairness after a model has already been trained. By setting the prefit parameter to True, it treats your existing model as a "black box," adjusting its decision thresholds for different groups to satisfy fairness constraints (like demographic parity or equalized odds) without changing the underlying model weights.

NEW QUESTION # 115
You use Azure Machine Learning to train models across multiple experiments by using the same workspace.
You must record training runs in a centralized location to compare results from different jobs.
During training, performance values must be captured so they appear in the experiment run history.
You need to configure experiment tracking.
What should you configure for each requirement? To answer, select the appropriate options in the answer area
. NOTE: Each correct selection is worth one point.
Answer:
Explanation:
Explanation:
Azure Machine Learning ' s experiment tracking is built around two complementary concepts. First, experiments are named containers that group related runs. By calling mlflow.set_experiment with an experiment name at the start of your training code, all subsequent runs are grouped under that experiment name in the AML workspace, creating the centralized record required. Second, metrics are scalar values such as accuracy, loss, or AUC that represent model performance. Calling mlflow.log_metric with a metric name and value during training persists these values to the run ' s record in the experiment history. These values appear on the Azure ML Studio run detail page and can be compared across runs using the experiment comparison view. Without set_experiment, runs fall into a default experiment. Without log_metric, the run history has no performance data to display or compare.

NEW QUESTION # 116
Drag and Drop Question
A team is developing a generative AI assistant. The team is experimenting with two prompt variants to improve performance before rolling out changes to production.
The team observes the following prompt results:
- PromptA variant generates longer responses and may be more expensive
to operate.
- PromptB may produce lower-quality answers.
The team must control operating costs while still selecting the better-performing prompt.
You need to identify cost drivers and compare the output quality of the two prompt variances to make an informed decision.
Which actions should you perform? To answer, move the appropriate actions to the correct requirements. 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.

NEW QUESTION # 117
Hotspot Question
You manage a Microsoft Foundry project. You build a solution that uses a set of PDF documents.
You require two large language models (LLMs):
- An embedding model must help categorize the documents.
- A general-purpose model must generate semantically and contextually
accurate output based on the documents.
You need to select benchmarks to observe the quality of the models.
Which metrics should you use for the benchmarks? To answer, select the appropriate options in the answer area.
NOTE: Each correct selection is worth one point.
Answer:
Explanation:
Explanation:
Box 1: Accuracy
Embedding model
An embedding model must help categorize the documents.
For an embedding model designed to categorize documents within Azure AI Foundry, cosine similarity is a crucial benchmark metric. It measures the semantic similarity between document embeddings, allowing you to assess how well the model groups related documents together.
Additionally, classification accuracy is important to evaluate how effectively the model assigns documents to predefined categories.
Classification Accuracy:
This metric measures the percentage of documents that are correctly categorized by the model. It directly reflects the model's ability to assign documents to the appropriate category based on their embeddings Box 2: Coherence General-purpose model A general-purpose model must generate semantically and contextually accurate output based on the documents.
Coherence evaluates how well the language model can produce output that flows smoothly, reads naturally, and resembles human-like language.
Incorrect:
* GPTsimilarity
GPT similarity refers to the ability of GPT models to assess and quantify the semantic similarity between pieces of text. This can be achieved by using the model to generate embeddings (numerical representations) of the text and then calculating the similarity (e.g., using cosine similarity) between these embeddings. Essentially, it allows you to determine how closely related two texts are in terms of their meaning.
