Question 1

A developer is building an application that gives users the ability to view bank account from multiple sources in a single dashboard. The developer has automated the process to retrieve API credentials for these sources. The process invokes an AWS Lambda function that is associated with an AWS CloudFormation cotton resource. The developer wants a solution that will store the API credentials with minimal operational overhead. When solution will meet these requirements?

A : Add an AWS Secrets Manager GenerateSecretString resource to the CloudFormation template. Set the value to reference new credentials to the Cloudformation resource.

B : Use the AWS SDK ssm PutParameter operation in the Lambda function from the existing, custom resource to store the credentials as a parameter. Set the parameter value to reference the new credentials. Set ma parameter type to SecureString.

C : Add an AWS Systems Manager Parameter Store resource to the CloudFormation template. Set the CloudFormation resource value to reference the new credentials Set the resource NoEcho attribute to true.

D : Use the AWS SDK ssm PutParameter operation in the Lambda function from the existing custom resources to store the credentials as a parameter. Set the parameter value to reference the new credentials. Set the parameter NoEcho attribute to true.

Answer: B

Question 2

A developer is creating an application that uses an AWS Lambda function to transform and load data from an Amazon S3 bucket. When the developer tests the application, the developer finds that some invocations of the Lambda function are slower than others. The developer needs to update the Lambda function to have predictable invocation durations that run with low latency. Any initialization activities, such as loading libraries and instantiating clients, must run during allocation time rather than during actual function invocations. Which combination of steps will meet these requirements? (Select TWO.)

A : Create a schedule group in Amazon EventBridge Scheduler to invoke the Lambda function.

B : Configure provisioned concurrency for the Lambda function to have the necessary number of execution environments.

C : Use the SLATEST version of the Lambda function.

D : Configure reserved concurrency for the Lambda function to have the necessary number of execution environments.

E : Deploy changes, and publish a new version of the Lambda function.

Answer: B,D

Question 3

A developer needs to export the contents of several Amazon DynamoDB tables into Amazon S3 buckets to comply with company data regulations. The developer uses the AWS CLI to run commands to export from each table to the proper S3 bucket. The developer sets up AWS credentials correctly and grants resources appropriate permissions. However, the exports of some tables fail. What should the developer do to resolve this issue?

A : Ensure that point-in-time recovery is enabled on the DynamoDB tables.

B : Ensure that the target S3 bucket is in the same AWS Region as the DynamoDB table.

C : Ensure that DynamoDB streaming is enabled for the tables.

D : Ensure that DynamoDB Accelerator (DAX) is enabled.

Answer: B

D : Ensure that DynamoDB Accelerator (DAX) is enabled.

Answer: B

Question 5

A company recently deployed an AWS Lambda function. A developer notices an increase in the function throttle metrics in Amazon CloudWatch.

What are the MOST operationally efficient solutions to reduce the function throttling? (Choose two.)

A : Migrate the function to Amazon Elastic Kubernetes Service (Amazon EKS).

B : Increase the maximum age of events in Lambda.

C : Increase the function’s reserved concurrency.

D : Add the lambda:GetFunctionConcurrency action to the execution role.

E : Request a service quota change for increased concurrency.

Answer: C,E
