Databricks Certified Machine Learning Professional Sample Questions (Q51-Q56):

NEW QUESTION # 51
A Machine Learning Engineer has deployed a customer churn prediction model to production three months ago. The model serves real-time predictions via a Databricks endpoint with inference logging enabled. They notice declining model accuracy in recent weeks and suspect data drift in customer demographics. They need to implement monitoring to track model performance degradation and input feature drift over time. Which monitoring profile type should they use?

A. Custom profile - Create a hybrid monitoring approach combining snapshot and time series profiles to capture both baseline comparisons and temporal trends.
B. Time series profile - Monitor the inference table using timestamp-based windows to track model performance and input drift over time.
C. Snapshot profile - Monitor the complete inference table to compare current model performance against the baseline established at deployment.
D. Inference profile - Monitor the inference table to track model performance metrics, prediction drift, and input feature drift across time windows.

Answer: D

Explanation:
The inference profile is designed specifically to monitor production model behavior using inference logs. It tracks model performance metrics, prediction distributions, and input feature drift across time windows, enabling detection of performance degradation and demographic data drift after deployment.

NEW QUESTION # 52
Which of the following describes concept drift?

A. Concept drift is when there is a change in the distribution of a target variable
B. Concept drift is when there is a change in the distribution of the predicted target given by the model
C. None of these describe Concept drift
D. Concept drift is when there is a change in the distribution of an input variable
E. Concept drift is when there is a change in the relationship between input variables and target variables

Answer: B

NEW QUESTION # 53
A Data Scientist needs to analyze drift detection results from Databricks Lakehouse Monitoring.
The system has generated both profile metrics and drift metrics tables. The scientist needs to identify baseline drift in numerical features by comparing current data against a baseline from 6 months ago. Which combination of table columns and values indicates baseline drift in a numerical feature?

A. log_type = "BASELINE" in profile metrics table with population_stability_index > 0.2 in drift metrics table.
B. drift_type = "BASELINE", ks_test.p_value < 0.05, and wasserstein_distance > 0.1.
C. window_cmp pointing to baseline time window and tv_distance > 0.5 with any drift_type value.
D. drift_type = "BASELINE", chi_squared_test.p_value < 0.05, and js_distance > 0.2.

Answer: B

Explanation:
Baseline drift is identified in the drift metrics table by setting drift_type to BASELINE, and for numerical features the drift statistics are the KS test (ks_test with a p-value indicating a statistically significant distribution change) and a numeric distance metric such as wasserstein_distance.

NEW QUESTION # 54
Which of the following is a drawback associated with using Jensen-Shannon (JS) distance for numeric feature drift detection?

A. None of these reasons
B. JS is not robust when working with large datasets
C. All of these reasons
D. JS requires a manual threshold or cutoff determinations

Answer: D

Explanation:
A key drawback of using Jensen-Shannon (JS) distance for numeric feature drift detection is that it requires manual threshold tuning to determine what level of divergence indicates significant drift. This makes automation and consistent interpretation challenging, especially across features or datasets with differing distributions.

NEW QUESTION # 55
A data scientist has computed updated feature values for all primary key values stored in the Feature Store table features. In addition, feature values for some new primary key values have also been computed. The updated feature values are stored in the DataFrame features_df. They want to replace all data in features with the newly computed data.
Which of the following code blocks can they use to perform this task using the Feature Store Client fs?

Answer: A
