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 the target S3 bucket is in the same AWS Region as the DynamoDB table.
B. Ensure that point-in-time recovery is enabled on the DynamoDB tables.
C. Ensure that DynamoDB streaming is enabled for the tables.
D. Ensure that DynamoDB Accelerator (DAX) is enabled.
正解：A

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?
A. Obtain the request identifier from the AWS request ID field in the event object. Configure the application to write logs to standard output.
B. Obtain the request identifier from the AWS request ID field in the context object. Configure the application to write logs to standard output.
C. Obtain the request identifier from the AWS request ID field in the event object. Configure the application to write logs to a file.
D. Obtain the request identifier from the AWS request ID field in the context object. Configure the application to write logs to a file.
正解：B
解説： https://docs.aws.amazon.com/lambda/latest/dg/nodejs-context.htmlhttps://docs.aws.amazon.com/lambda
/latest/dg/nodejs-logging.html
There is no explicit information for the runtime, the code is written in Node.js.
AWS Lambda is a service that lets developers run code without provisioning or managing servers. The developer can use the AWS request ID field in the context object to obtain a unique identifier for each function invocation. The developer can configure the application to write logs to standard output, which will be captured by Amazon CloudWatch Logs. This solution will meet the requirement of logging key events with a unique identifier.

A developer is testing an AWS Lambda function that has an event source of an Amazon Simple Queue Service (Amazon SQS) queue. The developer notices that some of the messages the Lambda function processes re-appear in the queue while the messages are being processed.
The developer must correct this behavior.
Which solution will meet this requirement?
A. Increase the memory allocation of the Lambda function.
B. Increase the timeout of the Lambda function.
C. Increase the batch size in the event source mapping.
D. Increase the visibility timeout of the SQS queue.
正解：D

A developer is implementing an AWS Cloud Development Kit (AWS CDK) serverless application.
The developer will provision several AWS Lambda functions and Amazon API Gateway APIs during AWS CloudFormation stack creation. The developer's workstation has the AWS Serverless Application Model (AWS SAM) and the AWS CDK installed locally.
How can the developer test a specific Lambda function locally?
A. Run the sam package and sam deploy commands. Create a Lambda test event from the AWS Management Console. Test the Lambda function.
B. Run the cdk synth and sam local start-lambda commands with the function construct identifier and the path to the synthesized CloudFormation template.
C. Run the cdk synth and sam local invoke commands with the function construct identifier and the path to the synthesized CloudFormation template.
D. Run the cdk synth and cdk deploy commands. Create a Lambda test event from the AWS Management Console. Test the Lambda function.

A developer is writing a web application that must share secure documents with end users. The documents are stored in a private Amazon S3 bucket. The application must allow only authenticated users to download specific documents when requested, and only for a duration of
15 minutes.
How can the developer meet these requirements?
A. Create a presigned S3 URL using the AWS SDK with an expiration time of 15 minutes.
B. Modify the S3 bucket policy to only allow specific users to download the documents. Revert the change after 15 minutes.
C. Use server-side encryption with AWS KMS managed keys (SSE-KMS) and download the documents using HTTPS.
D. Copy the documents to a separate S3 bucket that has a lifecycle policy for deletion after 15 minutes.
