With the rapid development of the world economy and frequent contacts between different countries, the talent competition is increasing day by day, and the employment pressure is also increasing day by day. Our company provides three different versions to choice for our customers. The software version of our AI-300 exam question has a special function that this version can simulate test-taking conditions for customers. If you feel very nervous about exam, we think it is very necessary for you to use the software version of our AI-300 Guide Torrent. The simulated tests are similar to recent actual exams in question types and degree of difficulty. By simulating actual test-taking conditions, we believe that you will relieve your nervousness before examination.

NEW QUESTION # 76
You have a Microsoft Foundry project.
You plan to use the Microsoft Foundry portal to fine-tune a base Azure OpenAI Service model that can accept both text and images as input.
You need to choose the suitable model.
Which model should you choose?
Answer: D
Explanation:
An appropriate base model for fine-tuning with text and image inputs in the Microsoft Foundry portal is GPT-4o (specifically versions like gpt-4o-2024-05-13 or newer). This model supports multi-modal training data, allowing you to improve performance on tasks requiring both visual understanding and textual response within Azure OpenAI Service.

NEW QUESTION # 77
Drag and Drop Question
A team iterates prompts used by a generative AI agent. The team must support internal review before releasing changes.
The team must:
- Track prompt changes with a clear history for audit and rollback.
- Compare prompt variants in parallel without affecting the prompt used in the production environment.
You need to select the appropriate source control approach for each requirement.
What should you use for each requirement? To answer, move the appropriate source controls to the correct requirements. You may use each source control 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.

Explanation:
NEW QUESTION # 78
You manage an Azure Machine Learning workspace that includes a batch endpoint. You plan to deploy a model to the batch endpoint. You need to configure compute for the deployment. Which compute should you use?
Answer: D
NEW QUESTION # 79
You are reviewing a dataset that will be used for an advanced fine-tuning job in Microsoft Foundry.
The fine-tuning job uses preference comparison data.
You review the following dataset excerpt.
For each of the following statements, select Yes if the statement is true. Otherwise, select No. NOTE: Each correct selection is worth one point.
Answer:
Explanation:
Explanation:
Preference comparison data with chosen versus rejected response pairs is the input format for Direct Preference Optimization (DPO) or RLHF-style fine-tuning - an advanced fine-tuning technique available in Microsoft Foundry. A valid DPO dataset record must have three fields: a prompt as the input, a chosen field containing the preferred response, and a rejected field containing the less preferred response. The file must be in JSONL format with UTF-8 encoding, where each line represents one complete preference pair. When evaluating statements about this dataset, mark True if the dataset contains all three required fields and chosen responses represent higher-quality outputs than rejected ones. Mark False if the format is incompatible with DPO requirements, if the required rejected field is missing, or if the chosen and rejected responses appear to be of equivalent quality with no clear preference signal.

NEW QUESTION # 80
Hotspot Question
You manage an Azure Machine Learning workspace by using the Python SDK v2.
You must create an automated machine learning job to generate a classification model by using data files stored in Parquet format. You must configure an autoscaling compute target and a data asset for the job.
You need to configure the resources for the job.
Which resource configuration should you use? To answer, select the appropriate options in the answer area.
NOTE: Each correct selection is worth one point.
Answer:
Explanation:
Explanation:
Box 1: Azure Databricks
Autoscaling: Out of the provided choices, Azure Databricks is the only compute target that natively supports the automated scaling up and down of worker nodes required to efficiently match the computation demands of your specific job.
Compatibility: Azure HDInsight and Azure Data Lake Analytics are legacy analytics platforms that do not offer the same direct, optimized, and auto-scaling compute integration within Azure ML SDK v2 pipelines for AutoML training.
Box 2: uri_folder
Directory access: Since your data consists of multiple data files stored in the Parquet format, pointing your asset type to a uri_folder allows the training job to automatically read and ingest all individual Parquet partition files stored inside that directory.
