Question 1

A developer is building an event-driven application by using AWS Lambda and Amazon EventBridge. The Lambda function needs to push events to an EventBridge event bus. The developer uses an SDK to run the PutEvents EventBridge action and specifies no credentials in the code. After deploying the Lambda function, the developer notices that the function is failing and there are AccessDeniedException errors in the logs.

How should the developer resolve this issue?

A : Configure a VPC peering connection between the Lambda function and EventBridge.

B : Modify their AWS credentials to include permissions for the PutEvents EventBridge action.

C : Modify the Lambda function execution role to include permissions for the PutEvents EventBridge action.

D : Add a resource-based policy to the Lambda function to include permissions for the PutEvents EventBridge action.

Answer: C

Question 2

A company needs a version control system for collaborative software development. The solution must include support for batches of changes across multiple files and parallel branching.

Which AWS service will meet these requirements?

A : Amazon S3

B : AWS CodeCommit

C : AWS CodeBuild

D : AWS CodePipeline

Answer: B

Question 3

A company stores customer credit reports in an Amazon S3 bucket. An analytics service uses standardAmazon S3 GET requests to access the reports. A developer must implement a solution to redact personallyidentifiable information (PII) from the reports before the reports reach the analytics service.

A : Load the S3 objects into Amazon Redshift by using a COPY command. Implement dynamic data masking. Refactor the analytics service to read from Amazon Redshift.

B : Set up an S3 Object Lambda function. Attach the function to an S3 Object Lambda Access Point. Program the function to call a PII redaction API.

C : Use AWS Key Management Service (AWS KMS) to implement encryption in the S3 bucket. Re-upload all the existing S3 objects. Give the kms permission to the analytics service.

D : Create an Amazon Simple Notification Service (Amazon SNS) topic. Implement message data protection. Refactor the analytics service to publish data access requests to the SNS topic.

Answer: B

Question 4

An application resizes images that are uploaded to an Amazon S3 bucket. Amazon S3 event notifications are used to trigger an AWS Lambda function that resizes the images. The processing time for each image is less than one second. A large amount of images are expected to be received in a short burst of traffic. How will AWS Lambda accommodate the workload?

A : Lambda will collect and then batch process the images in a single execution

B : Lambda will scale the memory allocated to the function to increase the amount of CPU available to process many images

C : Lambda will process the images sequentially in the order they are received

D : Lambda will scale out and execute the requests concurrently

Answer: D

Question 5

A developer is troubleshooting an application in an integration environment. In the application, an Amazon Simple Queue Service (Amazon SQS) queue consumes messages and then an AWS Lambda function processes the messages. The Lambda function transforms the messages and makes an API call to a third-party service.

There has been an increase in application usage. The third-party API frequently returns an HTTP 429 Too Many Requests error message. The error message prevents a significant number of messages from being processed successfully.

How can the developer resolve this issue?

A : Increase the SQS event source’s batch size setting.

B : Configure provisioned concurrency for the Lambda function based on the third-party API’s documented rate limits.

C : Increase the retry attempts and maximum event age in the Lambda function’s asynchronous configuration.

D : Configure maximum concurrency on the SQS event source based on the third-party service’s documented rate limits.

Answer: A
