Question # 9

A developer compiles an AWS Lambda function and packages the result as a .zip file. The developer uses the Functions page on the Lambda console to attempt to upload the local packaged .zip file. When pushing the package to Lambda, the console returns the following error:

Which solutions can the developer use to publish the code? (Select TWO.)

Upload the package to Amazon S3. Use the Functions page on the Lambda console to upload the package from the S3 location.

Create an AWS Support ticket to increase the maximum package size.

Use the update-function-code AWS CLI command. Pass the -publish parameter.

Repackage the Lambda function as a Docker container image. Upload the image to Amazon Elastic Container Registry {Amazon ECR). Create a new Lambda function by using the Lambda console. Reference the image that is deployed to Amazon ECR.

Sign the .zip file digitally. Create a new Lambda function by using the Lambda console. Update the configuration of the new Lambda function to include the Amazon Resource Name (ARN) of the code signing configuration.

Question # 10

A developer is building a serverless application by using AWS Serverless Application Model (AWS SAM) on multiple AWS Lambda functions.

When the application is deployed, the developer wants to shift 10% of the traffic to the new deployment of the application for the first 10 minutes after deployment. If there are no issues, all traffic must switch over to the new version.

Which change to the AWS SAM template will meet these requirements?

Set the Deployment Preference Type to Canary10Percent10Minutes. Set the AutoPublishAlias property to the Lambda alias.

Set the Deployment Preference Type to LinearlOPercentEvery10Minutes. Set AutoPubIishAIias property to the Lambda alias.

Set the Deployment Preference Type to CanaryIOPercentIOMinutes. Set the PreTraffic and PostTraffic properties to the Lambda alias.

Set the Deployment Preference Type to LinearlOPercentEveryIOMinutes. Set PreTraffic and Post Traffic properties to the Lambda alias.

Question # 11

A developer is creating an AWS Lambda function that will connect to an Amazon RDS for MySQL instance. The developer wants to store the database credentials. The database credentials need to be encrypted and the database password needs to be automatically rotated.

Which solution will meet these requirements?

Store the database credentials as environment variables for the Lambda function. Set the environment variables to rotate automatically.

Store the database credentials in AWS Secrets Manager. Set up managed rotation on the database credentials.

Store the database credentials in AWS Systems Manager Parameter Store as secure string parameters. Set up managed rotation on the parameters.

Store the database credentials in the X-Amz-Security-Token parameter. Set up managed rotation on the parameter.

Question # 12

A developer is building an application that will use an Amazon API Gateway API with an AWS Lambda backend. The team that will develop the frontend requires immediate access to the API endpoints to build the UI. To prepare the backend application for integration, the developer needs to set up endpoints. The endpoints need to return predefined HTTP status codes and JSON responses for the frontend team. The developer creates a method for an API resource.

Which solution will meet these requirements?

Set the integration type to AWS_PROXY. Provision Lambda functions to return hardcoded JSON data.

Set the integration type to MOCK. Configure the method ' s integration request and integration response to associate JSON responses with specific HTTP status codes.

Set the integration type to HTTP PROXY. Configure API Gateway to pass all requests to an external placeholder API, which the team will build.

Set the integration type to MOCK. Use a method request to define HTTP status codes. Use an integration request to define JSON responses.

Question # 13

A developer is creating an application that uses an Amazon DynamoDB table. The developer needs to develop code that reads all records that were added to the table during the previous day. creates HTML reports, and pushes the reports into third-party storage. The item size varies from 1 KB to 4 KB, and the index structure is defined with the date. The developer needs to minimize the read capacity that the application requires from the DynamoDB table.

Which DynamoDB API operation should the developer use in the code to meet these requirements?

Question # 14

A developer is storing sensitive data generated by an application in Amazon S3. The developer wants to encrypt the data at rest. A company policy requires an audit trail of when the AWS Key Management Service (AWS KMS) key was used and by whom.

Which encryption option will meet these requirements?

Server-side encryption with Amazon S3 managed keys (SSE-S3)

Server-side encryption with AWS KMS managed keys (SSE-KMS}

Server-side encryption with customer-provided keys (SSE-C)

Server-side encryption with self-managed keys

Question # 15

A developer is building a highly secure healthcare application using serverless components. This application requires writing temporary data to /Imp storage on an AWS Lambda function.

How should the developer encrypt this data?

Enable Amazon EBS volume encryption with an AWS KMS key in the Lambda function configuration so that all storage attached to the Lambda function is encrypted.

Set up the Lambda function with a role and key policy to access an AWS KMS key. Use the key to generate a data key used to encrypt all data prior to writing to Amp storage.

Use OpenSSL to generate a symmetric encryption key on Lambda startup. Use this key to encrypt the data prior to writing to /tmp.

Use an on-premises hardware security module (HSM) to generate keys, where the Lambda function requests a data key from the HSM and uses that to encrypt data on all requests to the function.

Question # 16

An application ingests data from an Amazon Kinesis data stream. The shards in the data stream are set for normal traffic.

During tests for peak traffic, the application ingests data slowly. A developer needs to adjust the data stream to handle the peak traffic.

What should the developer do to meet this requirement MOST cost-effectively?

Install the Kinesis Producer Library {KPL) to ingest data into the data stream.

Switch to on-demand capacity mode for the data stream. Specify a partition key when writing data to the data stream.

Decrease the amount of time that data is kept in the data stream by using the DecreaseStreamRetention Period API operation.

Increase the shard count in the data stream by using the UpdateShardCount API operation.
