Question #657 / 1019

A company manages multiple AWS accounts within an organization using AWS Organizations. The company has several global offices and needs to centrally manage security group rules to include new office CIDR ranges or remove outdated ones. The goal is to minimize administrative effort and costs when updating CIDR ranges across all accounts. Which solution MOST cost-effectively meets these requirements?

A

Deploy security groups in a central administrative account and share them across the organization using AWS Resource Access Manager (AWS RAM). Update these security groups manually when CIDR ranges change.

B

Create a customer-managed prefix list containing the CIDR ranges. Share the prefix list across the organization using AWS RAM. Reference the prefix list in all security group rules.

C

Use AWS Config to monitor CIDR range changes and trigger AWS Lambda functions to automatically update security groups in all accounts. Configure Amazon EventBridge to route change notifications.

D

Implement AWS Firewall Manager to create a security group policy that enforces CIDR ranges across the organization. Update the policy manually when CIDR ranges change.

Sample Questions

Question #22 / 529

A social media platform uses Amazon API Gateway, AWS Lambda, and Amazon DynamoDB for its backend services. Users have reported intermittent errors during POST requests, especially during peak hours. Investigation reveals that a few clients with high traffic are responsible for the majority of the errors. The platform's operations team notes that the errors are directly shown to end-users, leading to a poor user experience. The platform can tolerate occasional retries but needs to prevent user-facing errors.

What should the solutions architect do to mitigate this issue?

A

Implement retry logic with jitter and exponential backoff in the client SDK, ensuring errors are logged but not shown to users.

B

Configure API throttling using a usage plan in API Gateway and update clients to handle 429 HTTP status codes gracefully.

C

Enable DynamoDB auto-scaling to adjust capacity based on the traffic load and implement a backoff strategy in the Lambda functions.

D

Set up reserved concurrency for the Lambda functions to ensure consistent performance during traffic spikes.

Question #251 / 529

A company provides a REST API for six US-based partners to retrieve inventory data once daily using an Amazon API Gateway Regional endpoint. After deployment, the company observes 2,000 requests per second originating from 800 different IP addresses globally, suspected to be a botnet. The company needs to secure the API while minimizing costs.

Which approach should the company take to secure its API?

A

Create an Amazon CloudFront distribution with the API as the origin. Configure AWS WAF with a rule to block clients exceeding two requests per day. Associate the WAF web ACL with CloudFront. Use an origin access identity (OAI) to restrict API access to CloudFront. Require an API key for the GET method in API Gateway.

B

Create an Amazon CloudFront distribution with the API as the origin. Configure AWS WAF with a rule to allow only the partners' IP addresses. Associate the WAF web ACL with CloudFront. Add a custom header with an API key to the distribution. Require the API key for the GET method in API Gateway.

C

Create an AWS WAF web ACL to block all IPs except the partners'. Associate it with the API. Create a resource policy to throttle requests and attach it to the API. Require an API key for the GET method.

D

Create an AWS WAF web ACL to allow only the partners' IP addresses. Associate it with the API. Create a usage plan with a request limit and link it to the API. Generate an API key and add it to the usage plan.

Sample Questions

Question #239 / 557

A developer is deploying a web application behind an internet-facing Application Load Balancer (ALB) with an HTTPS listener. The developer has set up an Amazon Cognito user pool and needs to ensure that all access to the application is authenticated through Amazon Cognito.

What should the developer implement to meet this requirement?

A

Configure a listener rule to return a 403 Forbidden response if the Authorization header is missing.

B

Add an authentication action to the ALB listener rules with action type authenticate-cognito. Set OnUnauthenticatedRequest to \"deny\".

C

Use Amazon API Gateway with a Cognito user pool authorizer, forwarding requests to the ALB.

D

Create a Lambda function to validate the Cognito token in the Authorization header and attach it as a target to a new ALB listener.

Question #269 / 557

A developer is updating an AWS Lambda function with a new feature and wants to test it in production using 10% of the traffic. The Lambda function is integrated with an Amazon API Gateway REST API. The developer must ensure the API Gateway URL remains unchanged while testing the new version.

Which solution meets these requirements?

A

Create a new Lambda function version for the updated code. Configure API Gateway to use the new version. Deploy a new API Gateway stage with 10% traffic routing. Update the production stage to reference the new Lambda version.

B

Publish the updated Lambda function code to the $LATEST version. Create an alias pointing to $LATEST. Update the API Gateway integration to use the alias. Deploy the API Gateway to the existing production stage with 10% traffic allocation.

C

Publish a new version of the Lambda function. Create an alias for the production environment pointing to the original version. Configure a canary deployment in the API Gateway production stage, routing 10% of traffic to the new Lambda version via the alias. Update the alias to the new version after testing.

D

Deploy the updated Lambda function code as a new function. Create a new API Gateway resource linked to the new function. Use weighted routing in API Gateway to direct 10% of traffic to the new resource. Merge the resources after testing.
