NEW QUESTION # 170
Hotspot Question
You manage an Azure Machine Learning workspace by using the Python SDK v2.
You must create a compute cluster in the workspace. The compute cluster must run workloads and properly handle interruptions. You start by calculating the maximum amount of compute resources required by the workloads and size the cluster to match the calculations.
The cluster definition includes the following properties and values:
- name="mlcluster1"
- size="STANDARD_DS3_v2"
- min_instances=1
- max_instances=4
- tier="dedicated"
The cost of the compute resources must be minimized when a workload is active or idle. Cluster property changes must not affect the maximum amount of compute resources available to the workloads run on the cluster.
You need to modify the cluster properties to minimize the cost of compute resources.
Which properties should you modify? To answer, select the appropriate options in the answer area.
NOTE: Each correct selection is worth one point.
Answer:
Explanation:
Explanation:
Box 1: tier
Set tier to low_priority.
Lower your compute cluster cost with low priority VMs
Use any of these ways to specify a low-priority VM:
from azure.ai.ml.entities import AmlCompute
cluster_low_pri = AmlCompute(
name="low-pri-example",
size="STANDARD_DS3_v2",
min_instances=0,
max_instances=2,
idle_time_before_scale_down=120,
tier="low_priority",
)
ml_client.begin_create_or_update(cluster_low_pri).result()
Note: You may also to use low-priority VMs to run some or all of your workloads. These VMs don't have guaranteed availability and may be preempted while in use. You'll have to restart a preempted job.
Using Azure Low Priority Virtual Machines allows you to take advantage of Azure's unused capacity at a significant cost savings. At any point in time when Azure needs the capacity back, the Azure infrastructure will evict Azure Low Priority Virtual Machines. Therefore, Azure Low Priority Virtual Machines are great for workloads that can handle interruptions. The amount of available capacity can vary based on size, region, time of day, and more. When deploying Azure Low Priority Virtual Machines, Azure will allocate the VMs if there's capacity available, but there's no SLA for these VMs. An Azure Low Priority Virtual Machine offers no high availability guarantees. At any point in time when Azure needs the capacity back, the Azure infrastructure will evict Azure Low Priority Virtual Machines.
Incorrect:
* Size
Decrease of size would affect maximum amount of compute resources available to the workloads run on the cluster.
* max_instances
Decrease of max_instances would affect maximum amount of compute resources available to the workloads run on the cluster.
Box 2: min_instances
Use min_instances=0

NEW QUESTION # 171
Hotspot Question
You have an Azure Machine Learning workspace.
You plan to set up logging and tracking experiments by using MLflow Tracking.
You need to log the accuracy as a numerical value and the training loss as a plot.
How should you complete the commands? To answer, select the appropriate options in the answer area.
NOTE: Each correct selection is worth one point.
Answer:
Explanation:
Explanation:
Box 1: log_metric("log", num1)
Log Numerical Metrics
To track a single numerical value that changes over time (like accuracy or evaluation scores), you use the mlflow.log_metric() function. This enables Azure Machine Learning to plot the value on a performance graph automatically.
Box 2: log_artifact(img1)
Log Plots and FilesTo save external files, images, or plots generated during training, you use the mlflow.log_artifact() function. This uploads the specified file (in this case, your saved Matplotlib image) to the run's artifact storage.

NEW QUESTION # 172
You use the Azure Machine learning SDK v2 tor Python and notebooks to tram a model. You use Python code to create a compute target, an environment, and a taring script. You need to prepare information to submit a training job.
Which class should you use?
Answer: A
NEW QUESTION # 173
Fabrikam Inc. needs to improve the performance of a GPT-5 model based on the stated technical requirements.
Which action should you perform first?
Answer: D
Explanation:
The first action should be to evaluate the model output . Fabrikam already has evaluation data containing manually defined expected responses, and the technical requirements explicitly state that the organization must use its existing evaluation datasets based on real data with input-output pairs . Microsoft Foundry supports evaluating a model against an existing curated dataset to establish measurable baseline performance before optimization. Evaluation results can identify weaknesses in accuracy, relevance, groundedness, safety, or other quality dimensions and provide objective evidence for subsequent changes.
This sequencing is critical because Fabrikam also requires that advanced fine-tuning be applied only when prompt engineering is insufficient . Therefore, immediately fine-tuning the model would bypass the required baseline evaluation and optimization process. Fine-tuning should be driven by demonstrated performance gaps, not applied automatically.
Deploying directly to production is also inappropriate because leadership requires low operational risk and gradual rollout. Production traffic should not be used as the first evaluation mechanism when curated evaluation data already exists. Synthetic interaction data is useful when evaluation coverage is insufficient, but Microsoft specifically positions synthetic generation as an option when an adequate test dataset is unavailable. Fabrikam already has suitable evaluation data.
Study Guide Reference: Optimize generative AI systems and model performance - evaluate model performance, benchmark against curated datasets, iterate on prompts, and apply advanced fine-tuning when justified.
NEW QUESTION # 174
A team is building a generative AI agent by using Retrieval-Augmented Generation (RAG) in Microsoft Foundry.
The team frequently updates prompt content. The team must be able to track changes across contributors while avoiding full application redeployments.
You need to enable rapid prompt iteration with traceability. Applications consuming the agent must be able to use updated prompts without requiring redeployment.
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:
For tracking changes across contributors, Git integration is the answer: by connecting the Microsoft Foundry project to a Git repository, every prompt file change is tracked as a commit with author attribution, timestamp, and diff view, and pull requests enforce review before changes reach production. The Git history provides the complete audit trail and rollback capability needed for traceability. For allowing applications to consume updated prompts without requiring redeployment, Microsoft Foundry ' s prompt management feature allows prompts to be stored and versioned as named artifacts in the project. Applications reference prompts by name and load the latest approved version at inference time, rather than having prompt text hard-coded in the application deployment artifact. This decoupling means updating a prompt is a content operation - not a code deployment - so applications automatically pick up the new prompt without any redeployment.
