You create an Azure Machine Learning service datastore in a workspace. The datastore contains the following files:
* /data/2018/Q1.csv
* /data/2018/Q2.csv
* /data/2018/Q3.csv
* /data/2018/Q4.csv
* /data/2019/Q1.csv
All files store data in the following format:
id,f1,f2i
1,1.2,0
2,1,1,
1 3,2.1,0
You run the following code:

You need to create a dataset named training_data and load the data from all files into a single data frame by using the following code:

Solution: Run the following code:

Does the solution meet the goal?
  • Question 67

    You have a dataset that includes confidential dat
    a. You use the dataset to train a model.
    You must use a differential privacy parameter to keep the data of individuals safe and private.
    You need to reduce the effect of user data on aggregated results.
    What should you do?
  • Question 68

    You run a script as an experiment in Azure Machine Learning.
    You have a Run object named run that references the experiment run. You must review the log files that were generated during the experiment run.
    You need to download the log files to a local folder for review.
    Which two code segments can you run to achieve this goal? Each correct answer presents a complete solution.
    NOTE: Each correct selection is worth one point.
  • Question 69

    An IT department creates the following Azure resource groups and resources:

    The IT department creates an Azure Kubernetes Service (AKS)-based inference compute target named aks-cluster in the Azure Machine Learning workspace. You have a Microsoft Surface Book computer with a GPU. Python 3.6 and Visual Studio Code are installed.
    You need to run a script that trains a deep neural network (DNN) model and logs the loss and accuracy metrics.
    Solution: Install the Azure ML SDK on the Surface Book. Run Python code to connect to the workspace. Run the training script as an experiment on the aks-cluster compute target.
    Does the solution meet the goal?
  • Question 70

    You plan to use a Deep Learning Virtual Machine (DLVM) to train deep learning models using Compute Unified Device Architecture (CUDA) computations.
    You need to configure the DLVM to support CUDA.
    What should you implement?
