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.
You are configuring a batch processing job. What should you ensure about your input data?
AData must be encrypted only
BData is partitioned correctly
CData must be in JSON format
DData must be saved in Glacier
Explanation
Correct data partitioning is crucial for optimizing batch processing, while others are not universally required.
Q232
Which AWS service is best for deploying machine learning models at scale?
AAmazon SageMaker
BAWS Lambda
CAmazon S3
DAmazon RDS
Explanation
Amazon SageMaker simplifies model deployment, while the others serve different purposes.
Q233
A company needs to preprocess data for a training job without provisioning servers. What should they use?
AAmazon SageMaker Processing
BAWS Glue
CAmazon EC2
DAWS Data Pipeline
Explanation
Amazon SageMaker Processing is serverless for data preprocessing; the other options require more management.
Q234
What happens when you deploy an ML model with an AWS Lambda function with insufficient memory allocated?
AIncreased execution time
BFunction execution fails
CBilled for zero memory
DAWS Service shuts down
Explanation
Insufficient memory can cause function execution failure, while others do not typically occur.
Q235
Which AWS service is best for real-time data processing?
AAmazon Kinesis
BAmazon S3
CAWS Glue
DAmazon RDS
Explanation
Amazon Kinesis is designed for real-time data streams, while the others are for storage or batch processing.
Q236
A company needs to scale its ML model based on varying demand. Which AWS service should they consider?
AAWS Step Functions
BAWS Batch
CAmazon SageMaker
DAmazon DynamoDB
Explanation
Amazon SageMaker offers built-in scalability for ML model deployment compared to the other services listed.
Q237
What happens when an EC2 instance is stopped and started again?
ASame IP is retained
BAlways new IP allocated
CData on EBS is lost
DInstance type changes automatically
Explanation
Stopping and starting an EC2 instance often causes it to receive a new public IP, while EBS data remains intact.
Q238
A company needs to perform real-time analytics on streaming data. Which AWS service should they use?
AAmazon Kinesis
BAmazon S3
CAWS Glue
DAmazon RDS
Explanation
Amazon Kinesis is designed for real-time data processing, while the others are not suitable for streaming data.
Q239
You are training a model with AWS SageMaker using a large dataset stored in S3. What benefits do you gain from using SageMaker's built-in algorithms over your custom algorithm?
AHigher performance without optimization
BNo requirement for ML expertise
CManaged infrastructure and scalability
DUnlimited data size allowance
Explanation
SageMaker manages the infrastructure and scales automatically, unlike custom implementations.
Q240
What happens when you enable versioning on an S3 bucket?
AOlder files will be deleted
BFiles will be encrypted
CMultiple versions of objects are stored
DAccess speed is increased
Explanation
Enabling versioning allows multiple versions of the same object to be stored in the bucket, unlike the other options.
