The AWS Certified AI Practitioner (AIF-C01) exam validates your ability to understand and use AI services on AWS. It is ideal for individuals looking to demonstrate their knowledge of AI concepts and AWS services.
What happens when an IAM policy explicitly denies access, but another grants it?
AAccess is granted
BAccess is explicitly denied
CAccess is evaluated neutral
DAccess is granted if allowed earlier
Explanation
In AWS IAM, explicit denies take precedence over allows, enforcing security.
Q412
Which service is best for deploying machine learning models at scale?
AAmazon SageMaker
BAWS Glue
CAmazon RDS
DAWS CloudFormation
Explanation
Amazon SageMaker is designed specifically for deploying machine learning models, while the others serve different purposes.
Q413
You are configuring an AWS Lambda function triggered by an S3 upload. What happens when the Lambda function encounters an error?
ALambda retries automatically
BThe upload fails
CLambda logs the error only
DFunction runs without executing
Explanation
AWS Lambda automatically retries the invocation due to the error, while the other options do not reflect the service's error handling behavior.
Q414
A company needs to securely store sensitive data while maintaining fast access. Which AWS service combination should they use?
AAmazon S3 and Amazon Glacier
BAmazon RDS and EBS
CAmazon S3 with Server-Side Encryption
DAWS Secrets Manager only
Explanation
Amazon S3 provides fast access and supports Server-Side Encryption for security, while the other options do not meet both criteria effectively.
Q415
Which AWS service provides serverless compute capabilities?
AAWS Lambda
BEC2
CS3
DRDS
Explanation
AWS Lambda is the primary serverless compute service, while EC2 is for traditional servers, S3 is for storage, and RDS is for managed databases.
Q416
A company needs to securely share data across AWS accounts. What is the best approach?
AUse VPC Peering
BUse AWS Organizations
CUse S3 bucket policy
DUse CloudFront
Explanation
S3 bucket policies allow specific permissions for shared data access, while VPC Peering does not directly help with data sharing.
Q417
What happens when an IAM policy denies a user access to an action?
AAccess is granted if allowed elsewhere
BAccess request is ignored
CAccess is denied regardless of permissions
DUser can override the denial
Explanation
Deny policies take precedence in IAM, ensuring the action is denied regardless of other permissions.
Q418
Which AWS service provides a managed NoSQL database?
ADynamoDB
BRDS
CRedshift
DS3
Explanation
DynamoDB is exclusively a fully managed NoSQL database; RDS and Redshift are for relational and data warehousing, respectively, while S3 is an object storage service.
Q419
A company needs to ensure their S3 bucket is accessible only from specific IP ranges. What should they use?
ABucket Policy
BIAM Role
CCORS Configuration
DAWS Lambda
Explanation
Bucket Policy allows fine-grained access control, unlike IAM roles, CORS, or AWS Lambda, which don't directly secure access by IP.
Q420
You are configuring an Amazon SageMaker model. What happens if you select a higher instance type for training?
ALonger training time
BIncreased cost
CLower accuracy
DNo impact
Explanation
Selecting a higher instance type may reduce training time but incur greater costs; accuracy is not directly tied to instance type.
