Databricks Certified Machine Learning Professional Sample Questions (Q99-Q104):

NEW QUESTION # 99
Which of the following can be used to compare the relative prevalence of specific values in a single categorical variable between two datasets or time periods?

Answer: C

Explanation:
Contingency tables (also known as cross-tabulations) display the frequency distribution of categorical variables, allowing comparison of how specific category values occur across two datasets or time periods. This makes them effective for identifying categorical feature drift or shifts in value prevalence.


NEW QUESTION # 100
A data scientist has created a Python function compute_features that returns a Spark DataFrame with the following schema:

The resulting DataFrame is assigned to the features_df variable. The data scientist wants to create a Feature Store table using features_df.
Which of the following code blocks can they use to create and populate the Feature Store table using the Feature Store Client fs?

Answer: C


NEW QUESTION # 101
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 type of drift is present in the above scenario?

Answer: A


NEW QUESTION # 102
Which Spark ML class supports automated hyperparameter tuning?

Answer: A

Explanation:
CrossValidator performs:
parameter search
k-fold cross validation.


NEW QUESTION # 103
A Data Scientist is building a predictive maintenance model for a fleet of vehicles. They have two tables in their feature store:
1. A sensor_readings feature table with IoT data (e.g., engine_temp,
oil_pressure) streamed continuously. This is a time-series table with
vehicle_id as a primary key and ts as a timestamp key.
2. A maintenance_logs ground truth table that records when a vehicle
component failed. This table includes vehicle_id and the exact
failure_ts timestamp.
The goal is to create a training dataset by joining sensor_readings to maintenance_logs to train a model that predicts failures. They want to join the feature data with the ground truth data to ensure point-in-time correctness and prevent data leakage during model training.
Which approach will do this?

Answer: C

Explanation:
An AS OF join ensures point-in-time correctness by retrieving the most recent sensor readings that occurred at or before the failure timestamp for each vehicle. This guarantees that only information available prior to the failure event is used for training, preventing data leakage and aligning with best practices for time-series feature joins in predictive maintenance models.


NEW QUESTION # 104
......
