Question 1

A company is using Amazon API Gateway to invoke a new AWS Lambda function The company has Lambda function versions in its PROD and DEV environments. In each environment, there is a Lambda function alias pointing to the corresponding Lambda function version API Gateway has one stage that is configured to point at the PROD alias

The company wants to configure API Gateway to enable the PROD and DEV Lambda function versions to be simultaneously and distinctly available

Which solution will meet these requirements?

AEnable a Lambda authorizer for the Lambda function alias in API Gateway Republish PROD and create a new stage for DEV Create API Gateway stage variables for the PROD and DEV stages. Point each stage variable to the PROD Lambda authorizer to the DEV Lambda authorizer.

BSet up a gateway response in API Gateway for the Lambda function alias. Republish PROD and create a new stage for DEV. Create gateway responses in API Gateway for PROD and DEV Lambda aliases

CUse an environment variable for the Lambda function alias in API Gateway. Republish PROD and create a new stage for development. Create API gateway environment variables for PROD and DEV stages. Point each stage variable to the PROD Lambda function alias to the DEV Lambda function alias.

DUse an API Gateway stage variable to configure the Lambda function alias Republish PROD and create a new stage for development Create API Gateway stage variables for PROD and DEV stages Point each stage variable to the PROD Lambda function alias and to the DEV Lambda function alias

Correct : D

API Gateway Stages:Stages in API Gateway represent distinct environments (like PROD and DEV) allowing different configurations.

Stage Variables:Stage variables store environment-specific information, including Lambda function aliases.

Ease of Management:This solution offers a straightforward way to manage different Lambda function versions across environments.

Question 2

A developer is working on an ecommerce platform that communicates with several third-party payment processing APIs The third-party payment services do not provide a test environment.

The developer needs to validate the ecommerce platform's integration with the third-party payment processing APIs. The developer must test the API integration code without invoking the third-party payment processing APIs.

Which solution will meet these requirements'?

ASet up an Amazon API Gateway REST API with a gateway response configured for status code 200 Add response templates that contain sample responses captured from the real third-party API.

BSet up an AWS AppSync GraphQL API with a data source configured for each third-party API Specify an integration type of Mock Configure integration responses by using sample responses captured from the real third-party API.

CCreate an AWS Lambda function for each third-party API. Embed responses captured from the real third-party API. Configure Amazon Route 53 Resolver with an inbound endpoint for each Lambda function's Amazon Resource Name (ARN).

DSet up an Amazon API Gateway REST API for each third-party API Specify an integration request type of Mock Configure integration responses by using sample responses captured from the real third-party API

Correct : D

Mocking API Responses:API Gateway's Mock integration type enables simulating API behavior without invoking backend services.

Testing with Sample Data:Using captured responses from the real third-party API ensures realistic testing of the integration code.

Focus on Integration Logic:This solution allows the developer to isolate and test the application's interaction with the payment APIs, even without a test environment from the third-party providers.

Question 3

A developer is creating a simple proof-of-concept demo by using AWS CloudFormation and AWS Lambda functions The demo will use a CloudFormation template to deploy an existing Lambda function The Lambda function uses deployment packages and dependencies stored in Amazon S3 The developer defined anAWS Lambda Function resource in a CloudFormation template. The developer needs to add the S3 bucket to the CloudFormation template.

What should the developer do to meet these requirements with the LEAST development effort?

AAdd the function code in the CloudFormation template inline as the code property

BAdd the function code in the CloudFormation template as the ZipFile property.

CFind the S3 key for the Lambda function Add the S3 key as the ZipFile property in the CloudFormation template.

DAdd the relevant key and bucket to the S3Bucket and S3Key properties in the CloudFormation template

Correct : D

S3BucketandS3Key:These properties in a CloudFormationAWS::Lambda::Functionresource specify the location of the function's code in S3.

Least Development Effort:This solution minimizes code changes, relying on CloudFormation to reference the existing S3 deployment package.

Question 4

A company is planning to use AWS CodeDeploy to deploy an application to Amazon Elastic Container Service (Amazon ECS) During the deployment of a new version of the application, the company initially must expose only 10% of live traffic to the new version of the deployed application. Then, after 15 minutes elapse, the company must route all the remaining live traffic to the new version of the deployed application.

Which CodeDeploy predefined configuration will meet these requirements?

ACodeDeployDefault ECSCanary10Percent15Minutes

BCodeDeployDefault LambdaCanary10Percent5Minutes

CCodeDeployDefault LambdaCanary10Percent15Minutes

DCodeDeployDefault ECSLinear10PercentEvery1 Minutes

Correct : A

CodeDeploy Predefined Configurations:CodeDeploy offers built-in deployment configurations for common scenarios.

Canary Deployment:Canary deployments gradually shift traffic to a new version, ideal for controlled rollouts like this requirement.

CodeDeployDefault.ECSCanary10Percent15Minutes:This configuration matches the company's requirements, shifting 10% of traffic initially and then completing the rollout after 15 minutes.

Question 5

A company runs an application on AWS The application stores data in an Amazon DynamoDB table Some queries are taking a long time to run These slow queries involve an attribute that is not the table's partition key or sort key

The amount of data that the application stores in the DynamoDB table is expected to increase significantly. A developer must increase the performance of the queries.

Which solution will meet these requirements'?

AIncrease the page size for each request by setting the Limit parameter to be higher than the default value Configure the application to retry any request that exceeds the provisioned throughput.

BCreate a global secondary index (GSI). Set query attribute to be the partition key of the index

CPerform a parallel scan operation by issuing individual scan requests in the parameters specify the segment for the scan requests and the total number of segments for the parallel scan.

DTurn on read capacity auto scaling for the DynamoDB table. Increase the maximum read capacity units (RCUs).

Correct : B

Global Secondary Index (GSI):GSIs enable alternative query patterns on a DynamoDB table by using different partition and sort keys.

Addressing Query Bottleneck:By making the slow-query attribute the GSI's partition key, you optimize queries on that attribute.

Scalability:GSIs automatically scale to handle increasing data volumes.
