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 increase the instance size for an ML training job in SageMaker?
ACosts decrease immediately
BTraining time may decrease
CData privacy improves
DModel accuracy improves instantly
Explanation
Increasing instance size may decrease training time, while the other options are not directly related to instance size.
Q352
Which service is best for real-time data streaming in AWS?
AAmazon Kinesis
BAWS Lambda
CAmazon S3
DAmazon EC2
Explanation
Amazon Kinesis is specifically designed for real-time data streaming, while the others serve different purposes.
Q353
A company needs to automatically scale its machine learning workload based on demand. Which AWS service should it use?
AAWS Lambda
BAmazon SageMaker
CAWS Auto Scaling
DAWS Batch
Explanation
AWS Auto Scaling is designed for automatically scaling resources based on demand, while the others do not directly handle workload scaling.
Q354
What happens when you invoke a SageMaker endpoint with a missing input feature?
AReturns an error
BUses default value
CSuppresses feature influence
DApplies random forests
Explanation
Returning an error occurs because inputs must match the trained model's expected features, while the other options are incorrect assumptions.
Q355
Which service allows real-time stream processing of data?
AAmazon Kinesis
BAWS S3
CAmazon RDS
DAWS IAM
Explanation
Amazon Kinesis is designed for real-time analytics, while the others serve different purposes.
Q356
A company needs to train a model but has limited data resources. Which AWS service can help augment this data?
AAmazon SageMaker Ground Truth
BAWS Glue
CAmazon Lex
DAmazon Polly
Explanation
Amazon SageMaker Ground Truth helps create labeled datasets; the other options do not provide data augmentation techniques.
Q357
You are configuring a prediction endpoint in Amazon SageMaker. What should you ensure is enabled for better performance?
AIntegrated development environment
BMulti-model endpoint
CData versioning
DCheckpointing for models
Explanation
Multi-model endpoints in SageMaker optimize costs and performance for serving multiple models concurrently, unlike the other options.
Q358
Which AWS service is best for real-time data processing?
AAmazon Kinesis
BAmazon S3
CAWS Lambda
DAmazon RDS
Explanation
Amazon Kinesis is specifically designed for real-time data processing, unlike the others which serve different purposes.
Q359
A company needs to improve image classification accuracy. What should they first consider?
AIncreasing batch size
BAdjusting learning rate
CCollecting more training data
DChanging the optimizer used
Explanation
Collecting more training data can significantly improve model accuracy, more than simply adjusting settings.
Q360
You are configuring an Amazon SageMaker training job. What happens if the "MaxRuntimeInSeconds" is exceeded?
ATraining job pauses temporarily
BTraining job fails and stops
CTraining job continues without impact
DTraining job auto-saves and re-starts
Explanation
Exceeding "MaxRuntimeInSeconds" results in the training job failing and stopping immediately.
