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 real-time predictions for user queries. Which AWS service should they use?
AAmazon S3
BAmazon Kinesis
CAWS Batch
DAmazon Redshift
Explanation
Amazon Kinesis is designed for real-time data processing while the others are more suited for batch or storage.
Q402
What happens when you run a model without feature normalization?
AModel converges faster
BAccuracy may decrease
CTraining time decreases
DFeatures become irrelevant
Explanation
Lack of normalization can cause features with larger ranges to dominate, decreasing model accuracy.
Q403
Which AWS service is best for real-time data streaming?
AAmazon Kinesis
BAmazon S3
CAmazon RDS
DAmazon DynamoDB
Explanation
Amazon Kinesis is designed specifically for real-time streaming, while the others serve different purposes like storage and databases.
Q404
A company needs to host a machine learning model that can scale automatically. Which service should they choose?
AAWS Lambda
BAmazon SageMaker
CEC2 Spot Instances
DAmazon RDS
Explanation
Amazon SageMaker automatically manages scaling for deployed models, while the others do not focus specifically on ML model hosting.
Q405
What happens when you delete an S3 bucket that is not empty?
AYou must empty it first
BAll objects are deleted permanently
CYou receive a warning only
DARestoration tool is activated
Explanation
You must empty the bucket before deletion, otherwise the operation fails, and the other options are incorrect based on S3's behavior.
Q406
Which AWS service is best for deploying machine learning models at scale?
AAmazon SageMaker
BAWS Lambda
CAmazon EC2
DAmazon RDS
Explanation
Amazon SageMaker is specifically designed for building, training, and deploying ML models effectively, while others are for compute, database, or serverless computing.
Q407
A company needs to monitor the accuracy of its model predictions in real-time. What AWS service should they use?
AAmazon CloudWatch
BAWS Glue
CAmazon S3
DAWS Lambda
Explanation
Amazon CloudWatch is used for monitoring and logging metrics in real-time, while the other services focus on data integration or storage.
Q408
You are configuring a model to minimize bias during training. Which technique can help achieve this?
AData Augmentation
BOverfitting
CTraining with fewer features
DIncreased batch size
Explanation
Data Augmentation can help create a more balanced dataset, while the other options may lead to overfitting or other issues.
Q409
Which Amazon service is used for real-time stream processing?
AAmazon Kinesis
BAmazon S3
CAmazon EC2
DAmazon RDS
Explanation
Amazon Kinesis is specifically designed for processing streaming data in real-time, unlike the others that serve different purposes.
Q410
A company needs to deploy a scalable machine learning model on a serverless architecture. Which solution should they choose?
AAmazon SageMaker
BAWS Lambda
CAmazon EC2
DAWS Batch
Explanation
Amazon SageMaker provides built-in support for deploying models in serverless environments, while the others require more management.
