AWS Lambda@Edge enables you to run Lambda functions at __________ locations for improved latency.
- Cloud
- Data center
- Edge
- Regional
AWS Lambda@Edge enables you to run Lambda functions at edge locations for improved latency, allowing you to process data closer to the end user.
Scenario: You are designing a serverless architecture for a real-time analytics application. Which AWS service would you use to process incoming data streams and trigger AWS Lambda functions?
- Amazon Kinesis
- Amazon S3
- Amazon Redshift
- Amazon EC2
Amazon Kinesis is the correct option as it is designed for real-time processing of streaming data and can trigger AWS Lambda functions based on data events.
Scenario: Your team is concerned about optimizing the performance of AWS Lambda functions. What strategies would you recommend to minimize cold start times?
- Adding more logging statements
- Implementing provisioned concurrency
- Increasing memory allocation
- Reducing code size
Implementing provisioned concurrency is the recommended strategy to minimize cold start times in AWS Lambda functions as it allocates a set of concurrent executions to keep instances warm.
Scenario: You need to create a serverless API that triggers AWS Lambda functions based on HTTP requests. Which AWS service would you use to manage the API endpoints and integrate with AWS Lambda?
- Amazon API Gateway
- AWS Lambda itself
- Amazon SQS
- AWS Step Functions
Amazon API Gateway is the correct option as it is a fully managed service designed for managing API endpoints and integrating with AWS Lambda for triggering functions based on HTTP requests.
What are custom event sources in AWS Lambda?
- Built-in AWS services
- External services or applications
- Lambda-managed sources
- On-premises data centers
Custom event sources in AWS Lambda refer to external services or applications that can trigger the execution of Lambda functions by emitting custom events.
How do custom event sources differ from standard event sources in AWS Lambda?
- Customizability
- Built-in compatibility
- Scalability
- Performance
Custom event sources offer more flexibility and customization options compared to standard event sources, allowing developers to define their own event formats and sources.
What is the significance of integrating custom event sources with AWS Lambda?
- Cost reduction
- Extensibility
- Latency reduction
- Security enhancement
Integrating custom event sources with AWS Lambda extends the capabilities of Lambda functions, allowing them to respond to a wider range of events from external sources.
__________ is a common use case for custom event sources, allowing Lambda functions to respond to specific application events.
- Asynchronous processing
- Authentication
- Load balancing
- Synchronous processing
Asynchronous processing is a common use case for custom event sources in AWS Lambda, allowing functions to respond to specific application events.
AWS Lambda provides __________ for integrating with custom event sources, ensuring scalability and reliability.
- API gateways
- Backup services
- Event source mappings
- Resource pools
Event source mappings in AWS Lambda allow you to connect functions with event sources such as Amazon S3, Amazon SQS, and Amazon Kinesis, ensuring scalability and reliability.
Implementing custom event sources may require __________ to manage event routing and processing efficiently.
- Encryption keys
- Event routers
- Load balancers
- Message brokers
Message brokers such as Amazon SQS or Apache Kafka may be used to manage event routing and processing efficiently when implementing custom event sources in AWS Lambda.
