Databricks Certified Machine Learning Professional Sample Questions (Q29-Q34):

NEW QUESTION # 29
A Machine Learning Engineer has a production AI model that predicts fraudulent transactions in real time. This model is integrated into critical business workflows and any downtime could result in significant financial loss and regulatory penalties. The engineer needs to deploy a new, improved version of the model to production to replace the existing model. The bank's fairness policy requires that all transactions be exposed to the same model at any given time. Additionally, the deployment must meet the following requirements:
- Zero downtime: The fraud detection service must remain continuously
available to users and downstream systems.
- Immediate rollback: If the new model causes issues, you must be able
to revert to the previous version instantly.
Which deployment strategy meets these requirements?

A. Shadow
B. Rolling
C. Canary
D. Blue-Green

Answer: D

Explanation:
Blue-green deployment maintains two fully operational production environments and switches all traffic from the old model to the new model at once. This guarantees zero downtime and ensures that all transactions are handled by the same model version at any given time. If issues arise, traffic can be immediately switched back to the previous environment, enabling instant rollback while meeting strict fairness and availability requirements.

NEW QUESTION # 30
Why are Delta tables often used to store machine learning features?

A. They reduce model size
B. They allow faster GPU training
C. They replace Spark DataFrames
D. They support schema enforcement and time travel

Answer: D

Explanation:
Delta Lake provides:
ACID transactions
time travel
schema enforcement
These are essential for reproducible ML pipelines.

NEW QUESTION # 31
A machine learning engineer needs to deliver predictions of a machine learning model in real- time. However, the feature values needed for computing the predictions are available one week before the query time. Which feature is a benefit of using a batch serving deployment in this scenario rather than a real-time serving deployment where predictions are computed at query time?

A. There is no advantage to using batch serving deployments over real-time serving deployments
B. Querying stored predictions can be faster than computing predictions in real-time
C. Testing is not possible in real-time serving deployments
D. Computing predictions in real-time provides more up-to-date results
E. Batch serving has built-in capabilities in Databricks Machine Learning

Answer: E

NEW QUESTION # 32
A Machine Learning Engineer is using Lakehouse Monitoring to track the performance of ML models deployed in their environment. They want to monitor significant distributional drift in categorical features with a metric bounded on [0,1] for easy interpretation. Which statistical method should they use?

A. Jensen-Shannon Distance
B. Wasserstein Distance
C. Kullback-Leibler Distance
D. Kolmogorov-Smirnov Test

Answer: A

NEW QUESTION # 33
A machine learning engineer has developed a model and registered it using the FeatureStoreClient fs. The model has model URI model_uri. The engineer now needs to perform batch inference on customer-level Spark DataFrame spark_df, but it is missing a few of the static features that were used when training the model. The customer_id column is the primary key of spark_df and the training set used when training and logging the model.
Which of the following code blocks can be used to compute predictions for spark_df when the missing feature values can be found in the Feature Store by searching for features by customer_id?

A. fs.score_batch(model_uri, spark_df)
B. df = fs.get_missing_features(spark_df)
fs.score_batch(model_uri, df)
C. df = fs.get_missing_features(spark_df, model_uri)
fs.score_model(model_uri, df)
D. fs.score_model(model_uri, spark_df)
E. df = fs.get_missing_features(spark_df, model_uri)
fs.score_batch(model_uri, df)

Answer: A
