AWS Lambda functions invoked by S3 events receive information about the event, including the __________ that triggered the function.
- Bucket name
- Event timestamp
- Event type
- Object key
AWS Lambda functions invoked by S3 events receive information about the event, including the object key that triggered the function, allowing you to process the relevant object.
To filter S3 events based on object prefixes, you can specify a __________ in the event configuration.
- Metadata filter
- Prefix filter
- Size filter
- Suffix filter
To filter S3 events based on object prefixes, you can specify a prefix filter in the event configuration, allowing you to narrow down which objects trigger the Lambda function.
AWS Lambda can process S3 events in __________ mode, allowing you to handle high volumes of events.
- Batch
- Real-time
- Sequential
- Stream
AWS Lambda can process S3 events in batch mode, allowing it to handle high volumes of events efficiently by batching multiple events together for processing.
__________ is a feature of S3 events that enables you to customize the event notification content sent to AWS Lambda.
- Event filtering
- Event logging
- Event routing
- Event transformation
Event transformation is a feature of S3 event notifications that enables you to modify the content of the event before it's sent to AWS Lambda.
Cross-region replication of S3 events can be used to trigger AWS Lambda functions in __________ regions.
- Local
- Multiple
- Same
- Single
Cross-region replication of S3 events allows you to trigger AWS Lambda functions in multiple regions, enabling distributed processing of events.
Scenario: You are building a data processing pipeline that requires real-time analysis of images uploaded to an S3 bucket. How would you configure AWS Lambda to trigger image processing functions in response to S3 upload events?
- Configure an S3 event notification to trigger a Lambda function
- Poll the S3 bucket for changes periodically
- Use Amazon SNS to publish S3 events
- Use Amazon SQS to queue S3 events
Configuring an S3 event notification to trigger a Lambda function is the correct approach for real-time analysis of images uploaded to an S3 bucket.
How does AWS Lambda handle multiple SNS messages concurrently?
- By batching messages
- By limiting concurrency
- By pausing execution
- By scaling horizontally
AWS Lambda automatically scales horizontally to handle multiple SNS messages concurrently, spinning up additional instances of the function as needed.
What is a common use case for integrating SNS with AWS Lambda?
- Long-term data storage
- Machine learning model training
- Managing network traffic
- Processing real-time events
Integrating SNS with AWS Lambda allows for processing real-time events, such as notifications, updates, or alerts, with serverless functions.
What are the main benefits of using SNS triggers with AWS Lambda functions?
- Asynchronous event processing
- Cost optimization
- Load balancing
- Real-time data processing
SNS triggers enable AWS Lambda functions to process events asynchronously, allowing for scalable and responsive event-driven architectures.
How does AWS Lambda ensure the reliability of SNS triggers?
- By automatically retrying failed invocations
- By buffering messages before processing
- By delaying message delivery
- By discarding failed messages
AWS Lambda ensures the reliability of SNS triggers by automatically retrying failed invocations, ensuring that messages are processed reliably.
