Question 56

A developer is writing an AWS Lambda function. The developer wants to log key events that occur while the Lambda function runs. The developer wants to include a unique identifier to associate the events with a specific function invocation. The developer adds the following code to the Lambda function:

Which solution will meet this requirement?

Options:

Obtain the request identifier from the AWS request ID field in the context object. Configure the application to write logs to standard output.

Obtain the request identifier from the AWS request ID field in the event object. Configure the application to write logs to a file.

Obtain the request identifier from the AWS request ID field in the event object. Configure the application to write logs to standard output.

Obtain the request identifier from the AWS request ID field in the context object. Configure the application to write logs to a file.

Question 57

A developer is designing a serverless application for a game in which users register and log in through a web browser The application makes requests on behalf of users to a set of AWS Lambda functions that run behind an Amazon API Gateway HTTP API

The developer needs to implement a solution to register and log in users on the application's sign-in page. The solution must minimize operational overhead and must minimize ongoing management of user identities.

Which solution will meet these requirements'?

Options:

Create Amazon Cognito user pools for external social identity providers Configure 1AM roles for the identity pools.

Program the sign-in page to create users' 1AM groups with the 1AM roles attached to the groups

Create an Amazon RDS for SQL Server DB instance to store the users and manage the permissions to the backend resources in AWS

Configure the sign-in page to register and store the users and their passwords in an Amazon DynamoDB table with an attached IAM policy.

Question 58

A developer has an application that stores data in an Amazon S3 bucket. The application uses an HTTP API to store and retrieve objects. When the PutObject API operation adds objects to the S3 bucket the developer must encrypt these objects at rest by using server-side encryption with Amazon S3 managed keys (SSE-S3).

Which solution will meet this requirement?

Options:

Create an AWS Key Management Service (AWS KMS) key. Assign the KMS key to the S3 bucket.

Set the x-amz-server-side-encryption header when invoking the PutObject API operation.

Provide the encryption key in the HTTP header of every request.

Apply TLS to encrypt the traffic to the S3 bucket.

Question 59

A developer at a company recently created a serverless application to process and show data from business reports. The application's user interface (UI) allows users to select and start processing the files. The Ul displays a message when the result is available to view. The application uses AWS Step Functions with AWS Lambda functions to process the files. The developer used Amazon API Gateway and Lambda functions to create an API to support the UI.

The company's Ul team reports that the request to process a file is often returning timeout errors because of the see or complexity of the files. The Ul team wants the API to provide an immediate response so that the Ul can deploy a message while the files are being processed. The backend process that is invoked by the API needs to send an email message when the report processing is complete.

What should the developer do to configure the API to meet these requirements?

Options:

Change the API Gateway route to add an X-Amz-Invocation-Type header win a sialic value of 'Event' in the integration request Deploy the API Gateway stage to apply the changes.

Change the configuration of the Lambda function that implements the request to process a file. Configure the maximum age of the event so that the Lambda function will ion asynchronously.

Change the API Gateway timeout value to match the Lambda function ominous value. Deploy the API Gateway stage to apply the changes.

Change the API Gateway route to add an X-Amz-Target header with a static value of 'A sync' in the integration request Deploy me API Gateway stage to apply the changes.
