Question #29 / 1019

A company operates a Voice over Internet Protocol (VoIP) application that relies on UDP traffic. The application is hosted on Amazon EC2 instances within an Auto Scaling group across multiple AWS Regions. The company requires routing users to the Region offering the lowest latency while ensuring automatic failover if a Region becomes unavailable. Which solution fulfills these requirements?

A

Deploy a Network Load Balancer (NLB) linked to the Auto Scaling group via a target group. Configure AWS Global Accelerator with the NLB as an endpoint in each Region.

B

Deploy an Application Load Balancer (ALB) connected to the Auto Scaling group through a target group. Use AWS Global Accelerator with the ALB as an endpoint in each Region.

C

Deploy a Network Load Balancer (NLB) associated with the Auto Scaling group via a target group. Set up an Amazon Route 53 latency record pointing to each NLB. Integrate an Amazon CloudFront distribution with the latency record as its origin.

D

Deploy an Application Load Balancer (ALB) attached to the Auto Scaling group using a target group. Create an Amazon Route 53 weighted record aliased to each ALB. Configure an Amazon CloudFront distribution with the weighted record as its origin.

Question #564 / 1019

A company is developing a payment processing system and needs to securely store credit card details. The system must ensure that sensitive data remains encrypted at rest and is inaccessible to database administrators. Which solution meets these requirements?

A

Store data in an Amazon EBS volume encrypted using EBS encryption. Use IAM roles to control access.

B

Store data in Amazon DynamoDB. Use AWS KMS client-side encryption to encrypt data before storing it. Use IAM policies to restrict access.

C

Store data in Amazon S3 with server-side encryption using AWS KMS. Use bucket policies to restrict access.

D

Question #362 / 529

A company needs to monitor access patterns and object size distribution across Amazon S3 buckets in two AWS Regions to optimize storage costs. The company requires a centralized dashboard to visualize these metrics for the finance team. Which solution will meet these requirements with the LEAST operational overhead?

A

Deploy AWS Lambda functions in each Region to collect object size and access data. Store the data in Amazon DynamoDB and use Amazon QuickSight to build a custom dashboard with aggregated metrics for the finance team.

B

Create an Amazon EventBridge rule to capture S3 API events via AWS CloudTrail. Use a Lambda function to process the events and log metrics in Amazon CloudWatch. Build a CloudWatch dashboard to display the aggregated data.

C

Use the S3 Storage Lens default dashboard to track object size distribution and access patterns. Grant the finance team access to the dashboard directly in the S3 console.

D

Configure AWS Config rules in each Region to monitor S3 object sizes and access activity. Export the data to Amazon S3 and use Athena queries to generate reports for a custom QuickSight dashboard.

Question #327 / 529

A company is migrating its on-premises e-commerce platform to AWS. The application's database manages structured user profile data and temporary shopping cart data. The company needs to decouple the user profiles from the shopping cart data and implement replication in another AWS Region for disaster recovery. Which solution will meet these requirements with the HIGHEST performance?

A

Create an Amazon RDS DB instance with separate schemas for user profiles and shopping cart data. Configure a read replica for the DB instance in another Region.

B

Create an Amazon RDS DB instance to host the user profile data. Configure a read replica for the DB instance in another Region. Create a global datastore in Amazon ElastiCache for Memcached to host the shopping cart data.

C

Create two Amazon DynamoDB global tables. Use one global table for user profiles and the other for shopping cart data. Use DynamoDB Accelerator (DAX) for caching.

D

Create an Amazon RDS DB instance to host the user profile data. Configure a read replica for the DB instance in another Region. Create an Amazon DynamoDB global table to host the shopping cart data.

Sample Questions

Question #292 / 557

A developer is troubleshooting duplicate notifications in a company's application. The application uses an Amazon SQS queue where messages are sent. An AWS Lambda function processes these messages and sends notifications via Amazon Simple Notification Service (SNS). Users report receiving duplicate notifications during peak traffic times. What are possible reasons for this? (Choose two.)

A

Standard SQS queues provide at-least-once message delivery.

B

Standard SQS queues guarantee exactly-once processing, so duplicates must be due to application logic errors.

C

Amazon SNS has incorrect topic permissions, leading to message reprocessing.

D

The SQS queue's visibility timeout is less than the Lambda function's timeout.

E

The Lambda function's execution role lacks permissions to publish to SNS.

Question #26 / 557

A developer is building an order processing system deployed on AWS Lambda. Each order is assigned a unique identifier, and the system may experience sudden spikes in order requests at any time. During throttling events, the system might retry requests. The system must ensure that each order is processed exactly once, even if duplicate requests are sent. Which solution will meet these requirements?

A

Create an Amazon RDS for PostgreSQL DB instance. Store the unique order identifier in a database table. Configure the Lambda function to query the table for the identifier before processing the order.

B

Create an Amazon DynamoDB table. Store the unique order identifier in the table. Configure the Lambda function to check the table for the identifier before processing the order.

C

Create an Amazon DynamoDB table. Store the unique order identifier in the table. Modify the Lambda function to return an error response if a duplicate order identifier is detected.

D

Create an Amazon ElastiCache for Redis cluster. Store the unique order identifier in the cache. Configure the Lambda function to check the cache for the identifier before processing the order.
