Q112
Which service can automatically scale based on application load?
AAWS Lambda
BAmazon EC2 Auto Scaling
CAWS CloudFormation
DAmazon RDS
Explanation
Amazon EC2 Auto Scaling adjusts instance count based on load; Lambda is event-driven only, CloudFormation provisions resources, and RDS does not auto-scale automatically without additional configuration.
Q113
A company needs to invoke an AWS Lambda function upon a new object upload to S3. Which service should be configured?
AAWS CloudTrail
BAmazon S3 Event Notifications
CAWS Config
DAWS Step Functions
Explanation
Amazon S3 Event Notifications can trigger Lambda on uploads; CloudTrail logs actions, AWS Config monitors resources, and Step Functions orchestrates workflows rather than triggering on events directly.
Q114
You are configuring an S3 bucket to be publicly accessible to read objects. What will happen if you enable public access settings?
ABucket policy will automatically allow all access
BObjects are accessible regardless of ACLs
CPublic access settings override IAM policies
DAccess denied if block public access is active
Explanation
Enabling block public access settings will deny all public access regardless of bucket policies or ACLs; options A, B, and C misinterpret how public access settings function in conjunction with IAM and bucket policies.
