Question 1

A company is using Amazon API Gateway to develop an API for its application on AWS. A developer needs to test and generate API responses. Other teams are required to test the API immediately.

What should the developer do to meet these requirements?

A : Set up a mock integration request in API Gateway. Configure the method's integration request and integration response to associate a response with a given status code.

B : Set up the request validators in the API's OpenAPI definition file. Import the OpenAPI definitions into API Gateway to test the API.

C : Set up a gateway response for the API in API Gateway. Configure response headers with hardcoded HTTP status codes and responses.

D : Set up a request parameter-based Lambda authorizer to control access to the API. Configure the Lambda function with the necessary mapping template.

Answer: A

Question 2

A developer received the following error message during an AWS CloudFormation deployment:

DELETE_FAILED (The following resource(s) failed to delete: (sg-11223344).)

Which action should the developer take to resolve this error?

A : Manually delete the security group. Then execute a change set to force deletion of the CloudFormation stack.

B : Add a DependsOn attribute to the sg-11223344 resource in the CloudFormation template. Then delete the stack.

C : Update the logical ID of the security group resource with the security groups ARN. Then delete the stack.

D : Modify the CloudFormation template to retain the security group resource. Then manually delete the resource after deployment.

Answer: D

Question 3

A financial services company has developed a REST API which is deployed in an Auto Scaling Group behind an Application Load Balancer. The API stores the data payload in DynamoDB and the static content is served through S3. Upon analyzing the usage pattern, it's found that 80% of the read requests are shared across all users.

As a Developer Associate, how can you improve the application performance while optimizing the cost with the least development effort?

A : Enable ElastiCache Redis for DynamoDB and ElastiCache Memcached for S3

B : Enable DynamoDB Accelerator (DAX) for DynamoDB and CloudFront for S3

C : Enable DAX for DynamoDB and ElastiCache Memcached for S3

D : Enable ElastiCache Redis for DynamoDB and CloudFront for S3

Answer: B

B : Install the CloudWatch agent on the on-premises servers and EC2 instances

C : Use CloudWatch for monitoring EC2 instances and custom AWS CLI scripts using the put-metric-data API

D : Install the CloudWatch agent on the EC2 instances and use a cron job on the on-premises servers

Question 5

company has a mobile app. The app includes an Amazon API Gateway REST API that invokes AWS Lambda functions. The Lambda functions process data from the app.

The company needs to test updated Lambda functions that have new features. The company must conduct these tests with a subset of users before deployment. The tests must not affect other users of the app.

Which solution will meet these requirements with the LEAST amount of operational effort?

A : Create a new version of each Lambda function with a weighted alias. Configure a weight value for each version of the Lambda function. Update the new weighted alias Amazon Resource Name (ARN) in the REST API.

B : Create a new REST API in API Gateway. Set up a Lambda proxy integration to connect to multiple Lambda functions. Enable canary settings on the deployment stage. Specify a smaller percentage of API traffic to go to the new version of the Lambda function.

C : Create a new version of each Lambda function. Integrate a predefined canary deployment in AWS CodeDeploy to slowly shift the traffic to the new versions automatically.

D : Create a new REST API in API Gateway. Set up a Lambda non-proxy integration to connect to multiple Lambda functions. Specify the necessary parameters and properties in API Gateway. Enable canary settings on the deployment stage. Specify a smaller percentage of API traffic to go to the new version of the Lambda function.

Answer: C
