Question #547 / 1019

A company operates a fleet of connected vehicles that continuously transmit telemetry data. The company requires a solution to ingest and process this high-velocity data in near real-time, storing it in Amazon S3 for later analysis. The architecture must scale automatically with varying data loads and minimize administrative efforts. Which solution meets these requirements with the LEAST operational overhead?

A

Use Amazon Kinesis Data Firehose to deliver streaming data to Amazon S3.

B

Use AWS Glue to deliver streaming data to Amazon S3.

C

Use AWS Lambda to deliver streaming data and store the data to Amazon S3.

D

Use AWS Database Migration Service (AWS DMS) to deliver streaming data to Amazon S3.

Question #699 / 1019

A

Use Amazon EKS with AWS Fargate. Attach an Amazon EBS volume to the pods and mount it as persistent storage.

B

Use Amazon ECS with AWS Fargate. Configure an Amazon EFS file system and mount it as a persistent volume in the containers.

C

Use Amazon ECS with EC2 launch type. Create an Amazon EBS volume attached to EC2 instances and mount it in the containers.

D

Sample Questions

Question #521 / 529

A company is restructuring its patching process for Amazon EC2 instances in its application account. Currently, instances are patched over the internet using a NAT gateway in the application account's VPC.

The company maintains a patch repository hosted on EC2 instances within a dedicated private VPC in a separate core account. They plan to use AWS Systems Manager Patch Manager with this repository to patch the application account's EC2 instances. The solution must ensure that EC2 instances in the application account cannot access the internet.

Additionally, these EC2 instances require connectivity to Amazon DynamoDB for application data and to Systems Manager for management tasks. They also need access to the patch repository in the core account's VPC.

Which solution meets these requirements?

A

Create a security group that denies all outbound traffic. Associate it with all EC2 instances in the application account. Establish a VPN connection between the application account's VPC and the core account's VPC. Create VPC endpoints for DynamoDB and Systems Manager. Update route tables in both accounts.

B

Deploy VPC endpoints for DynamoDB and Systems Manager. Remove the NAT gateway from the application account's VPC. Set up a VPC peering connection between the application and core accounts. Modify route tables in both VPCs to allow traffic through the peering connection.

C

Implement a network ACL blocking all outbound traffic on ports 80 and 443. Associate this NACL with the application account's subnets. Use AWS Direct Connect to establish a private connection to the core account's VPC. Create a gateway endpoint for DynamoDB.

D

Delete the NAT gateway in the application account's VPC. Create a transit gateway to connect the application and core account VPCs. Configure VPC endpoints for DynamoDB and Systems Manager. Update the route tables to route traffic through the transit gateway.

Question #10 / 529

A retail company operates its ecommerce application on AWS. The application runs on Amazon EC2 instances behind an Application Load Balancer (ALB), with Amazon RDS as the database backend. Amazon CloudFront is configured with the ALB as its origin, caching static content. Amazon Route 53 manages DNS. After an update, the ALB intermittently returns a 504 status code (Gateway Timeout) due to backend latency. Users see the default ALB error page, but reloading the page resolves the issue temporarily. The solutions architect must implement a custom error page with minimal operational overhead.

A

Create an Amazon S3 bucket to host a static error page. Upload the custom error page to S3.

B

Configure a CloudWatch alarm for the ALB's HTTPCodeTargetTimeout_Count metric. Use a Lambda function to redirect traffic to a backup server.

C

Modify Route 53 health checks to route traffic to an S3-hosted error page when health checks fail.

D

Use Lambda@Edge to intercept 504 errors and redirect requests to a static error page hosted on S3.

E

Configure CloudFront to return a custom error page for HTTP 504 status codes, pointing to the S3-hosted error page.

Sample Questions

Question #546 / 557

A developer is designing an authentication system for a web application. The application must allow users to register, log in, and securely interact with backend AWS services. Which approach fulfills these requirements?

D

Provision an Amazon Cognito identity pool linked to an identity provider. Define IAM roles for authenticated users to access AWS services. Integrate the identity pool with the web application to handle authentication and authorization.

A

Use AWS IAM to create a policy granting access to the necessary services. Establish an IAM role and attach the policy. Integrate the role with the application's authentication provider via AWS STS.

B

Set up an Amazon API Gateway with IAM authorization. Create an IAM role with appropriate permissions and attach it to the API Gateway. Integrate the API endpoint with the web application for user authentication.

C

Create an Amazon Cognito user pool with multi-factor authentication and password policies. Configure an app client and integrate it with the web app. Use the user pool tokens to access AWS resources directly.

Question #300 / 557

A developer must obtain approval from a security team before deploying code changes to production using AWS CodePipeline. The developer uses an Amazon Simple Notification Service (Amazon SNS) topic to notify the security team. What is the MOST operationally efficient way to implement this approval process within the pipeline?

A

Add a new stage to CodePipeline before the production deployment stage. Include a manual approval action in the new stage. Configure a notification rule in the pipeline settings to trigger the SNS topic using its ARN when manual approval is required.

B

Develop an AWS Lambda function that sends a notification via the SNS topic and waits for approval. Add a new stage to CodePipeline before production deployment and integrate the Lambda function as a custom action.

C

Add a manual approval action to the existing staging stage in CodePipeline. Specify the SNS topic's ARN during the approval action configuration to notify the security team.

D

Modify the CodePipeline settings to create a new notification rule targeting the SNS topic. Set the rule to trigger on manual approval events without adding a new stage to the pipeline.
