Demo Questions

Question 1
A machine learning engineer is converting a Hyperopt-based hyperparameter tuning process from manual MLflow logging to MLflow Autologging. They are trying to determine how to manage nested Hyperopt runs with MLflow Autologging.
Which of the following approaches will create a single parent run for the process and a child run for each unique combination of hyperparameter values when using Hyperopt and MLflow Autologging?
  1. Starting a manual parent run before calling fmin
  2. Ensuring that a built-in model flavor is used for the model logging
  3. Starting a manual child run within the objective_function
  4. There is no way to accomplish nested runs with MLflow Autologging and Hyperopt
  5. MLflow Autologging will automatically accomplish this task with Hyperopt
Correct answer: A
Question 2
Which of the following MLflow operations can be used to automatically calculate and log a Shapley feature importance plot?
  1. mlflow.shap.log_explanation
  2. None of these operations can accomplish the task.
  3. mlflow.shap
  4. mlflow.log_figure
  5. client.log_artifact
Correct answer: A
Question 3
A machine learning engineer is in the process of implementing a concept drift monitoring solution. They are planning to use the following steps:
1. Deploy a model to production and compute predicted values
2. Obtain the observed (actual) label values
3. _____
4. Run a statistical test to determine if there are changes over time
Which of the following should be completed as Step #3?
  1. Obtain the observed values (actual) feature values
  2. Measure the latency of the prediction time
  3. Retrain the model
  4. None of these should be completed as Step #3
  5. Compute the evaluation metric using the observed and predicted values
Correct answer: E
Question 4
A machine learning engineer wants to log feature importance data from a CSV file at path importance_path with an MLflow run for model model.
Which of the following code blocks will accomplish this task inside of an existing MLflow run block?
  3. mlflow.log_data(importance_path, "feature-importance.csv")
  4. mlflow.log_artifact(importance_path, "feature-importance.csv")
  5. None of these code blocks tan accomplish the task.
Correct answer: D
Question 5
A data scientist is using MLflow to track their machine learning experiment. As a part of each MLflow run, they are performing hyperparameter tuning. The data scientist would like to have one parent run for the tuning process with a child run for each unique combination of hyperparameter values.
They are using the following code block:
The code block is not nesting the runs in MLflow as they expected.
Which of the following changes does the data scientist need to make to the above code block so that it successfully nests the child runs under the parent run in MLflow?
  1. Indent the child run blocks within the parent run block
  2. Add the nested=True argument to the parent run
  3. Remove the nested=True argument from the child runs
  4. Provide the same name to the run_name parameter for all three run blocks
  5. Add the nested=True argument to the parent run and remove the nested=True arguments from the child runs
Correct answer: A
Question 6
A machine learning engineer is monitoring categorical input variables for a production machine learning application. The engineer believes that missing values are becoming more prevalent in more recent data for a particular value in one of the categorical input variables.
Which of the following tools can the machine learning engineer use to assess their theory?
  1. Kolmogorov-Smirnov (KS) test
  2. One-way Chi-squared Test
  3. Two-way Chi-squared Test
  4. Jenson-Shannon distance
  5. None of these
Correct answer: B
Question 7
Which of the following describes concept drift?
  1. Concept drift is when there is a change in the distribution of an input variable
  2. Concept drift is when there is a change in the distribution of a target variable
  3. Concept drift is when there is a change in the relationship between input variables and target variables
  4. Concept drift is when there is a change in the distribution of the predicted target given by the model
  5. None of these describe Concept drift
Correct answer: C
Question 8
Which of the following operations in Feature Store Client fs can be used to return a Spark DataFrame of a data set associated with a Feature Store table?
  1. fs.create_table
  2. fs.write_table
  3. fs.get_table
  4. There is no way to accomplish this task with fs
  5. fs.read_table
Correct answer: E
Question 9
A data scientist wants to remove the star_rating column from the Delta table at the location path. To do this, they need to load in data and drop the star_rating column.
Which of the following code blocks accomplishes this task?
  1. spark.read.format(“delta”).load(path).drop(“star_rating”)
  2. spark.read.format(“delta”).table(path).drop(“star_rating”)
  3. Delta tables cannot be modified
  4. spark.read.table(path).drop(“star_rating”)
  5. spark.sql(“SELECT * EXCEPT star_rating FROM path”)
Correct answer: A
Question 10
A data scientist has developed a model to predict ice cream sales using the expected temperature and expected number of hours of sun in the day. However, the expected temperature is dropping beneath the range of the input variable on which the model was trained.
Which of the following types of drift is present in the above scenario?
  1. Label drift
  2. None of these
  3. Concept drift
  4. Prediction drift
  5. Feature drift
Correct answer: E
Question 11
A data scientist has developed and logged a scikit-learn random forest model model, and then they ended their Spark session and terminated their cluster. After starting a new cluster, they want to review the feature_importances_ of the original model object.
Which of the following lines of code can be used to restore the model object so that feature_importances_ is available?
  1. mlflow.load_model(model_uri)
  2. client.list_artifacts(run_id)["feature-importances.csv"]
  3. mlflow.sklearn.load_model(model_uri)
