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 deploy a machine learning model in production. Which AWS service should they use for real-time inference?
AAmazon SageMaker
BAmazon S3
CAmazon Redshift
DAWS Lambda
Explanation
Amazon SageMaker provides a fully managed service for deploying machine learning models with real-time inference; S3 is for storage, Redshift for data warehousing, and Lambda for serverless computations.
Q302
What happens when you delete an Amazon S3 bucket that contains objects?
AOnly the objects are deleted
BBucket is deleted, objects are retained
CBucket deletion fails
DBucket and all objects are deleted
Explanation
When you delete an S3 bucket, it deletes both the bucket and all its objects permanently; retention is not an option.
Q303
You are configuring IAM roles for a data scientist to train models using AWS SageMaker. What is a best practice?
AGrant admin access to all services
BUse least privilege access
CAttach the default role
DAllow unrestricted access to S3
Explanation
Using least privilege access ensures the data scientist has only necessary permissions, enhancing security; other options pose excessive risk.
Q304
Which service is best for real-time data streaming?
AAmazon Kinesis
BAmazon S3
CAmazon RDS
DAWS Lambda
Explanation
Amazon Kinesis is designed specifically for real-time data streaming, whereas the others serve different purposes.
Q305
A healthcare company wants to predict patient outcomes based on historical data. Which AWS service should they use?
AAmazon Comprehend
BAWS SageMaker
CAmazon QuickSight
DAWS Glue
Explanation
AWS SageMaker is tailored for building, training, and deploying machine learning models.
Q306
What happens when you incorrectly configure IAM permissions for a SageMaker role?
AJob runs but outputs are empty
BJob fails and returns an error
CPermissions are ignored completely
DJob runs with reduced performance
Explanation
Incorrect IAM permissions will lead to job failures, as required access is not granted.
Q307
Which service is ideal for deploying machine learning models at scale?
AAmazon SageMaker
BAWS Glue
CAmazon RDS
DAmazon EC2
Explanation
Amazon SageMaker is specifically built for deploying ML models, while others serve different purposes.
Q308
A company needs to process streaming data in real-time for its fraud detection system. Which AWS service should they use?
AAmazon S3
BAmazon Kinesis
CAWS Lambda
DAWS Batch
Explanation
Amazon Kinesis is designed for real-time streaming data, unlike the others which serve different use cases.
Q309
You are configuring an IAM policy that denies all actions for a specific S3 bucket. What will happen if you grant another policy that allows access to that bucket?
AAccess is granted due to explicit allow.
BAccess is denied due to explicit deny.
CAn error occurs during policy evaluation.
DAccess is granted temporarily.
Explanation
By default, explicit denies take precedence over allows in IAM policy evaluation.
Q310
Which service is best for deploying machine learning models at scale?
AAWS Lambda
BAmazon SageMaker
CAWS EC2
DAWS Glue
Explanation
Amazon SageMaker is specifically designed for ML model deployment, unlike others which serve different purposes.
