AWS Certified Developer - Associate Certification - Part 1
3. A Developer is investigating an issue whereby certain requests are passing through an Amazon API Gateway endpoint /MyAPI, but the requests do not reach the AWS Lambda function backing /MyAPI. The Developer found that a second Lambda function sometimes runs at maximum concurrency allowed for the given AWS account. How can the Developer address this issue?
A) Add another API Gateway stage for /MyAPI, and shard the requests
B) Configure the second Lambda function - s concurrency execution limit
C) Manually reduce the concurrent execution limit at the account level
D) Reduce the throttling limits in the API Gateway /MyAPI endpoint
4. A Developer created a new AWS account and must create a scalable AWS Lambda function that meets the following requirements for concurrent execution: Average execution time of 100 seconds 50 requests per second Which step must be taken prior to deployment to prevent errors?
A) Contact AWS Support to increase the concurrent execution limits
B) Implement dead-letter queues to capture invocation errors
C) Add an event source from Amazon API Gateway to the Lambda function
D) Implement error handling within the application code
5. An application is expected to process many files. Each file takes four minutes to process each AWS Lambda invocation. The Lambda function does not return any important data. What is the fastest way to process all the files?
A) Make asynchronous
B) First split the files to make them smaller, then process with synchronous
C) First join all the files, then process it all at once with an asynchronous
D) Make synchronous
