QUESTION 440
A developer is building a microservice that uses AWS Lambda to process messages from an Amazon Simple Queue Service (Amazon SQS) standard queue. The Lambda function calls external APIs to enrich the SQS message data before loading the data into an Amazon Redshift data warehouse. The SQS queue must handle a maximum of 1,000 messages per second.
During initial testing, the Lambda function repeatedly inserted duplicate data into the Amazon Redshift table. The duplicate data led to a problem with data analysis. All duplicate messages were submitted to the queue within 1 minute of each other.
How should the developer resolve this issue?
A. Create an SQS FIFO queue. Enable message deduplication on the SQS FIFO queue.
B. Reduce the maximum Lambda concurrency that the SQS queue can invoke.
C. Use Lambda’s temporary storage to keep track of processed message identifiers
D. Configure a message group ID for every sent message. Enable message deduplication on the SQS standard queue.
Answer: A
QUESTION 441
A company has an application that uses an Amazon API Gateway API to invoke an AWS Lambda function. The application is latency sensitive.
A developer needs to configure the Lambda function to reduce the cold start time that is associated with default scaling.
What should the developer do to meet these requirements?
A. Publish a new version of the Lambda function. Configure provisioned concurrency. Set the provisioned concurrency limit to meet the company requirements.
B. Increase the Lambda function’s memory to the maximum amount. Increase the Lambda function’s reserved concurrency limit.
C. Increase the reserved concurrency of the Lambda function to a number that matches the current production load.
D. Use Service Quotas to request an increase in the Lambda function’s concurrency limit for the AWS account where the function is deployed.
Answer: A
QUESTION 442
A developer is deploying an application on Amazon EC2 instances that run in Account A. The application needs to read data from an existing Amazon Kinesis data stream in Account B.
Which actions should the developer take to provide the application with access to the stream? (Choose two.)
A. Update the instance profile role in Account A with stream read permissions.
B. Create an IAM role with stream read permissions in Account B.
C. Add a trust policy to the instance profile role and IAM role in Account B to allow the instance profile role to assume the IAM role.
D. Add a trust policy to the instance profile role and IAM role in Account B to allow reads from the stream.
E. Add a resource-based policy in Account B to allow read access from the instance profile role.
