Question #634 / 1019

A manufacturing company stores 15 TB of sensor data daily in an Amazon S3 bucket within a central data account. The company has three internal departments (Quality, Maintenance, and Production) that require read-only access to this data for analysis. The company needs to share the data securely while minimizing administrative overhead and avoiding public exposure. Which solution best meets these requirements?

A

Use S3 Cross-Region Replication to copy the data to separate buckets in each department's account.

B

Generate pre-signed URLs for the S3 bucket and distribute them to department heads temporarily.

C

Configure S3 bucket policies to grant cross-account read access to the respective department accounts.

D

Create IAM roles in the central data account for each department and share credentials with their teams.

Question #639 / 1019

A gaming platform is experiencing performance issues due to uneven traffic distribution across its backend servers. The platform uses an Application Load Balancer (ALB) to route traffic to Amazon EC2 instances deployed in multiple Availability Zones within a VPC. Monitoring shows that one EC2 instance is handling a disproportionate share of requests, leading to increased latency. What should the solutions architect recommend to address this issue?

A

Disable session affinity (sticky sessions) on the ALB

B

Replace the ALB with a Gateway Load Balancer

C

Increase the number of EC2 instances in each Availability Zone

D

Modify the health check thresholds on the ALB's target group

Sample Questions

Question #410 / 529

A company is using AWS Control Tower to manage AWS accounts in an organization in AWS Organizations. The company has an OU containing accounts. The company must prevent any new or existing Amazon S3 buckets in the OU's accounts from being configured with public access. Which solution will meet these requirements?

A

Configure AWS Systems Manager to run automation scripts that detect and remove public access settings from all S3 buckets in the OU's accounts. Schedule the automation to run periodically.

B

Implement the AWS Control Tower proactive control to check whether S3 buckets in the OU's accounts have public access enabled. Set the BlockPublicAccess property to true. Attach the proactive control to the OU.

C

Create an SCP that denies the s3:PutBucketPolicy and s3:PutBucketPublicAccessBlock actions for all buckets in the OU's accounts. Attach the SCP to the OU.

D

Create an AWS Config custom rule to detect S3 buckets with public access enabled. Configure a remediation action using AWS Lambda to enforce Block Public Access settings on non-compliant buckets.

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.
