What happens when you call a Lambda function configured with a reserved concurrency of 5?
A
It runs up to 5 instances simultaneously.
B
It queues the excess invocations.
C
It errors out on the sixth invocation.

Which service is best for real-time data streaming?
A
Amazon Kinesis
B
Amazon S3
C
AWS Lambda
D
Amazon EC2

A company needs to deploy a machine learning model with zero downtime. What is the best practice?
A
Use Blue/Green deployment
B
Use a single instance
C
Switch off old version immediately
D
Deploy during peak traffic

A
SageMaker fails the pipeline
B
SageMaker ignores the entire dataset
C
SageMaker can complete with imputation

SageMaker can handle missing values by using imputation techniques, while the other options aren't valid practices.
Which service is best for real-time streaming data processing?
A
Amazon Kinesis
B
AWS S3
C
AWS Glue
D
Amazon RDS
Amazon Kinesis is designed for real-time data capture, while the others focus on storage or batch processing.
A company needs to identify fraudulent transactions in real-time. What AWS service should they use?
A
Amazon SageMaker
B
AWS Lambda
C
Amazon CloudWatch
D
Amazon Athena
Amazon SageMaker can build, train, and deploy ML models for real-time fraud detection, whereas the others serve different purposes.
You are configuring an IAM policy. What happens if the policy explicitly denies access?
A
Access is always denied
B
Access is granted if allowed elsewhere
C
Access is conditioned on resource type
D
Access could be granted temporarily
An explicit deny in IAM policies takes precedence over any allows.
