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.
What happens when you specify an incorrect instance type for a machine learning model in Amazon SageMaker?
AModel fails to deploy
BModel trains successfully
CAWS charges double fees
DService recommends a valid type
Explanation
An incorrect instance type leads to a deployment failure.
Q172
Which AWS service is best for deploying machine learning models at scale?
AAmazon SageMaker
BAWS Lambda
CAWS Glue
DAmazon EC2
Explanation
Amazon SageMaker is specifically designed for deploying ML models, while the others serve different purposes.
Q173
A company needs to classify images using a pre-trained model. What should they use?
AAWS Lambda
BAmazon Rekognition
CAmazon S3
DAWS Batch
Explanation
Amazon Rekognition offers image classification capabilities, while the others do not focus specifically on image processing.
Q174
You are configuring an IAM role for a SageMaker training job. What must you ensure?
ARole has access only to CloudWatch
BRole can access S3 where data is stored
CRole can access DynamoDB tables only
DRole must have no permissions
Explanation
The role needs S3 access to retrieve training data, while the other options either restrict access unnecessarily or are irrelevant.
Q175
Which service is best for real-time data streaming?
AAmazon Kinesis
BAmazon S3
CAWS Lambda
DAmazon RDS
Explanation
Amazon Kinesis is designed for real-time data streaming, while S3 stores data at rest, Lambda executes code, and RDS is meant for relational databases.
Q176
A company needs to deploy a machine learning model quickly without managing infrastructure. Which AWS service should they use?
AAmazon SageMaker
BAWS Batch
CAWS Glue
DAWS CodeBuild
Explanation
Amazon SageMaker allows quick model deployment with minimal infrastructure management, while others focus on batch processing or ETL tasks.
Q177
What happens when you set a model's performance threshold in Amazon SageMaker?
AIncreases training time
BDecreases model accuracy
CTriggers automatic retraining
DAllows to evaluate against that threshold
Explanation
Setting a performance threshold allows evaluating model performance but does not auto-retrain or change accuracy and training time directly.
Q178
Which AWS service is best for building real-time analytics applications?
AAmazon Kinesis
BAmazon RDS
CAWS Lambda
DAWS Glue
Explanation
Amazon Kinesis is designed for real-time data processing, while the others focus on databases or batch processing.
Q179
A company wants to deploy a machine learning model within a serverless architecture. Which service should they use?
AAmazon SageMaker
BAmazon EC2
CAWS Fargate
DAWS Lambda
Explanation
AWS Lambda allows for serverless execution, while the others involve more management.
Q180
You are configuring an S3 bucket. What happens when you disable public access on a bucket?
AAll current permissions are revoked
BNo new public ACLs can be added
CPublic data can still be accessed
DOnly bucket owner retains access
Explanation
Disabling public access prevents new public ACLs, but does not affect existing ones immediately.
