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.
Which AWS service is best for real-time analytics of streaming data?
AAmazon Kinesis
BAmazon S3
CAWS Lambda
DAmazon Redshift
Explanation
Amazon Kinesis is specifically designed for real-time processing of streaming data, while the others serve different purposes.
Q62
A company needs low-latency access to machine learning models from edge devices. Which AWS service should they use?
AAmazon SageMaker
BAWS Greengrass
CAmazon EMR
DAWS Glue
Explanation
AWS Greengrass enables running ML models on edge devices, while the others are not optimized for low-latency operations at the edge.
Q63
What happens when you change the instance type of a running EC2 instance?
AInstance stops and starts
BInstance continues without interruptions
CData is lost permanently
DOnly network settings reset
Explanation
Changing the instance type requires the instance to stop and start, which may cause a brief downtime and will not result in data loss if volumes are properly managed.
Q64
Which service allows model training on specific datasets in AWS?
AAmazon SageMaker
BAWS Lambda
CAmazon RDS
DAmazon S3
Explanation
Amazon SageMaker is designed for model training, while the others have different purposes.
Q65
A company needs to analyze large datasets in near real-time. Which AWS service should they use?
AAWS Glue
BAmazon Kinesis
CAmazon RDS
DAmazon S3
Explanation
Amazon Kinesis is designed for real-time data processing, unlike the other options which are suited for different data operations.
Q66
You are configuring a model in SageMaker and need to deploy multiple endpoints. What is the most efficient way to minimize costs?
AUse multi-container endpoints
BDeploy single endpoints only
CEnable data capture
DUse SageMaker Batch Transform
Explanation
Multi-container endpoints optimize resource use for multiple models, while the other options may not minimize costs effectively.
Q67
A company needs to store unstructured data at scale and retrieve it efficiently. Which service should they use?
AAmazon S3
BAmazon RDS
CAWS Lambda
DDynamoDB
Explanation
Amazon S3 is ideal for large-scale unstructured data storage, while RDS is for structured data, Lambda runs code, and DynamoDB is a NoSQL database.
Q68
What happens when a machine learning model deployed on SageMaker is under heavy load?
AAutomatically scales instances
BStops responding until load decreases
CSends alerts to the developer
DReduces model accuracy to manage load
Explanation
SageMaker can automatically scale based on demand, while the other options incorrectly represent the service's behavior.
Q69
You are configuring an IAM role for an EC2 instance running a machine learning model. Which action should you grant to allow access to S3 buckets?
As3:GetJob
Bs3:AllowAccess
Cs3:ListBucket
Ds3:DescribeBuckets
Explanation
s3:ListBucket allows the EC2 instance to list the contents of the bucket, while the others are invalid IAM actions for this purpose.
Q70
Which service provides real-time data processing for streaming data?
AAWS Glue
BAmazon Kinesis
CAWS Batch
DAmazon Redshift
Explanation
Amazon Kinesis is designed for processing streaming data in real time; the other options serve different purposes.
