The build pipeline has an AWS CodeArtifact repository where artifacts of thebuild are published. The developer needs a solution that requires minimum changes to the build pipeline.Which solution meets these requirements?

A : Modify the existing CodeArtifact repository to associate an upstream repository with the publicpackage repository.

B : Create a new CodeArtifact repository that has an external connection to the public package repository.

C : Create a new CodeArtifact domain that contains a new repository that has an external connection to thepublic package repository.

D : Modify the CodeArtifact repository resource policy to allow artifacts to be fetched from the publicpackage repository.

Answer: A

Question 2

A : AWS X-Ray

Question 3

A developer supports an application that accesses data in an Amazon DynamoDB table. One of the itemattributes is expirationDate in the timestamp format. The application uses this attribute to find items, archivethem, and remove them from the table based on the timestamp valueThe application will be decommissioned soon, and the developer must find another way to implement thisfunctionality. The developer needs a solution that will require the least amount of code to write.Which solution will meet these requirements?

A : Enable TTL on the expirationDate attribute in the table. Create a DynamoDB stream. Create an AWSLambda function to process the deleted items. Create a DynamoDB trigger for the Lambda function.

B : Create two AWS Lambda functions one to delete the items and one to process the items Create aDynamoDB stream Use the Deleteltem API operation to delete the items based on the expirationDateattribute Use the GetRecords API operation to get the items from the DynamoDB stream and processthem

C : Create two AWS Lambda functions, one to delete the items and one to process the items. Create anAmazon EventBndge scheduled rule to invoke the Lambda Functions Use the Deleteltem API operationto delete the items based on the expirationDate attribute. Use the GetRecords API operation to get theitems from the DynamoDB table and process them.

D : Enable TTL on the expirationDate attribute in the table Specify an Amazon Simple Queue Service(Amazon SQS > dead-letter queue as the target to delete the items Create an AWS Lambda function toprocess the items

Answer: A

Question 4

A developer is designing an event-driven architecture. An AWS Lambda function that processes data needs topush processed data to a subset of four consumer Lambda functions. The data must be routed based on thevalue of one field in the data.Which solution will meet these requirements with the LEAST operational overhead?

A : Create an Amazon Simple Queue Service {Amazon SQS) queue and even! source mapping for eachconsumer Lambda function. Add message routing logic to the data-processing Lambda function.

B : Create an Amazon Simple Notification Service (Amazon SNS) topic. Subscribe the four consumerLambda functions to the topic. Add message filtering logic to each consumer Lambda function.Subscribe the data-processing Lambda function to the SNS topic.

C : Create a separate Amazon Simple Notification Service (Amazon SNS) topic and subscription for eachconsumer Lambda function. Add message routing logic to the data-processing Lambda function topublish to the appropriate topic.

D : Create a single Amazon Simple Notification Service {Amazon SNS) topic. Subscribe the fourconsumer Lambda functions to the topic. Add SNS subscription filter policies to each subscription.Configure the data-processing Lambda function to publish to the topic.

Answer: B

Question 5

A developer is building a serverless application by using AWS Serverless Application Model (AWS SAM) onmultiple AWS Lambda functions. When the application is deployed, the developer wants to shift 10% of thetraffic to the new deployment of the application for the first 10 minutes after deployment. If there are noissues, all traffic must switch over to the new version.Which change to the AWS SAM template will meet these requirements?

A : Set the Deployment Preference Type to Canaryl OPercent10Minutes. Set the AutoPublishAlias propertyto the Lambda alias.

B : Set the Deployment Preference Type to Linearl OPercentEveryIOMinutes. Set AutoPubIishAIiasproperty to the Lambda alias.

C : Set the Deployment Preference Type to Canaryl OPercentIOMinutes. Set the PreTraffic and PostTrafficproperties to the Lambda alias.

D : Set the Deployment Preference Type to Linearl OPercentEvery10Minutes. Set PreTraffic andPostTraffic properties to the Lambda alias.

Answer: A
