Which AWS service is best for serverless applications?
AAWS Lambda
BAmazon EC2
CAWS Batch
DAmazon ECS

Q452
A company needs high availability for a website. What should they implement?
ASingle EC2 instance
BAWS Auto Scaling
CElastic Load Balancing
DAmazon S3
Explanation
Elastic Load Balancing distributes traffic across multiple instances, ensuring high availability, while the others do not guarantee this level of protection.
Q453
You are configuring cross-region replication in S3. What happens if an object is deleted in the source bucket?
AIt's automatically deleted in the target bucket
BIt remains in the target bucket
CThe replication stops
DOnly metadata is deleted
Explanation
Cross-region replication does not replicate deletions; thus, the object remains in the target bucket after deletion.
Q454
A company needs to ensure its EC2 instances are launched in multiple Availability Zones for high availability. Which service should it use?
AAWS Auto Scaling
BAWS Elastic Load Balancing
CAWS CloudFormation
DAWS Elastic Beanstalk
Explanation
AWS Auto Scaling allows instances to be launched across multiple AZs, enhancing availability. Other options do not inherently manage instance distribution across AZs.
Q455
What happens when an AWS Lambda function times out?
AIt restarts automatically
BThe function returns null
CIt raises a timeout error
DThe function schedules a retry
Explanation
When a Lambda function times out, it raises a timeout error, and execution is stopped. Restarting or null return are not automatic behaviors.

Q459
You are configuring an S3 bucket for hosting a static website. What happens if the indexing document is not specified?
AWebsite won't load
