The AWS Certified Machine Learning Engineer – Associate (MLA-C01) exam validates your skills in building, training, and deploying machine learning models on AWS. It is ideal for those looking to specialize in machine learning.
A company needs to predict customer churn using historical data. What is the first step in their machine learning process?
AModel training
BData preprocessing
CFeature engineering
DModel evaluation
Explanation
Data preprocessing is essential before moving to training, features, or evaluation.
Q252
You are configuring a training job in SageMaker and must choose an instance type. What happens if you select an instance with less memory than required?
AThe job will run efficiently
BSageMaker will automatically scale up
CThe job will fail
DThere will be a delay in execution
Explanation
Choosing insufficient memory will cause the job to fail, unlike the other options which are incorrect.
Q253
Which AWS service provides a fully managed message broker?
AAmazon MQ
BAmazon SNS
CAWS Lambda
DAmazon SQS
Explanation
Amazon MQ is a fully managed message broker, whereas SNS is for notifications, SQS is for queues, and Lambda is serverless compute.
Q254
A company needs to monitor model drift in their machine learning application. Which service should they utilize?
AAmazon SageMaker Model Monitor
BAWS CloudTrail
CAmazon CloudWatch
DAWS Config
Explanation
Amazon SageMaker Model Monitor is specifically designed to track model drift, while the other options are for general monitoring and logging.
Q255
You are configuring an AWS Glue job to extract data from S3. What happens if the IAM role does not have the correct permissions?
AJob fails due to access denied
BJob runs but with no data
CData is partially extracted
DJob automatically requests permissions
Explanation
The job fails with access denied error if the IAM role lacks permissions, while the other options misstate the behavior.
Q256
Which service is best for real-time data processing?
AAmazon Kinesis
BAmazon S3
CAWS Lambda
DAmazon EC2
Explanation
Amazon Kinesis is designed for real-time data streaming, while others focus on storage or compute tasks.
Q257
A company needs to regularly customize machine learning models based on new training data. Which AWS service should they use?
AAmazon Sagemaker
BAWS Glue
CAmazon Athena
DAWS Batch
Explanation
Amazon SageMaker provides tools for building and retraining models efficiently, unlike the others which serve different purposes.
Q258
You are configuring IAM permissions for a data scientist. What would happen if you apply restrictive permissions?
AThey can still access all resources.
BThey may be unable to access required resources.
CTheir permissions become irrelevant.
DThey will automatically gain admin privileges.
Explanation
Restrictive permissions can limit access to necessary resources for the data scientist's work, impacting their effectiveness.
Q259
Which service is optimal for deploying a model as an API?
AAmazon SageMaker
BAWS Lambda
CAmazon EC2
DAmazon Athena
Explanation
Amazon SageMaker streamlines model deployment as an API, while Lambda is for serverless functions and EC2 is more complex.
Q260
A company needs to automate model retraining based on incoming data. Which AWS service should they use?
AAWS Glue
BAmazon EventBridge
CAWS CodePipeline
DAmazon S3
Explanation
Amazon EventBridge can trigger retraining workflows based on events, unlike the others which are not designed for event-driven automation.
