질문 # 79
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, df)
B. df = fs.get_missing_features(spark_df, model_uri)
fs.score_batch(model_uri, df)
df = fs.get_missing_features(spark_df)
C. fs.score_batch(model_uri, spark_df)
D. fs.score_model(model_uri, spark_df)
E. df = fs.get_missing_features(spark_df, model_uri)
fs.score_model(model_uri, df)

정답：C

질문 # 80
A machine learning engineer wants to programmatically create a new Databricks Job whose schedule depends on the result of some automated tests in a machine learning pipeline. Which Databricks tool can be used to programmatically create the Job?

A. MLflow Client
B. Jobs cannot be created programmatically
C. MLflow APIs
D. Databricks REST APIs
E. AutoML APIs

정답：D

질문 # 81
A Data Scientist has created a sales forecasting model, named sales-forecasting. The model is deployed to a model serving endpoint with a schema. They need to invoke this model using Python and would prefer to use a SDK function to make the request. Which method suits these requirements?

A. Use the built in ai_query function and provide the endpoints and request parameters.
B. Make an API request to the MODEL_VERSION_URI and provide the dataframe_split as the request parameter.
C. Import the MLflow Deployments class and use the ai_query method and provide the endpoints and request parameters.
D. Import the MLflow Deployments class and use the predict method and provide the endpoint and input parameters.

정답：D

설명：
The MLflow Deployments SDK provides a predict method specifically designed to invoke Databricks model serving endpoints from Python. This method abstracts the HTTP request details, allows specifying the endpoint name directly, and cleanly passes input parameters that conform to the model's serving schema, making it the preferred SDK-based approach.

질문 # 82
A machine learning engineer is in the process of implementing a feature drift monitoring solution.
They are planning to use the following steps:
1. Measure the distributions of each feature variable in the training
set
2. Deploy a model to production
3. Measure the distributions of each feature variable in inference
4. _______
Which action should be completed as Step #4?

A. Measure the latency of the model's prediction time
B. Retrain the model based on any new feature variables that have been added to the feature set
C. Obtain the observed values (actual) feature values and compare to the predicted values
D. Run a statistical test to determine if there are changes in the feature variable distribution over time

정답：D

설명：
The final step in a feature drift monitoring solution is to run a statistical test (e.g., Kolmogorov- Smirnov test) to determine whether the feature distributions in production have significantly diverged from those in the training set. This helps detect drift and maintain model reliability.

질문 # 83
A machine learning engineer has a machine learning pipeline where predictions are updated annually. The final prediction dataset contains millions of rows, and that dataset is irregularly accessed. Which solution should the machine learning engineer use to maintain cost efficiency?

A. On-premises low-latency database
B. Cloud-based object storage
C. Cloud-based low latency database
D. Cloud-based in-memory instance of a Spark DataFrame

정답：B

설명：
For data that is large in size, infrequently accessed, and updated only periodically, cloud-based object storage (such as AWS S3, Azure Blob Storage, or Google Cloud Storage) is the most cost- efficient option. It offers durable, scalable, and inexpensive storage compared to in-memory or low-latency databases, which are optimized for frequent access and real-time performance rather than long-term, infrequent retrieval.
