• Question 1032:

  A company runs a Windows-based ecommerce application on Amazon EC2 instances. The application has a very high transaction rate. The company requires a durable storage solution that can deliver 200,000 IOPS for each EC2 instance.

  Which solution will meet these requirements?

  A. Host the application on EC2 instances that have Provisioned IOPS SSD (io2) Block Express Amazon Elastic Block Store (Amazon EBS) volumes attached.
  B. Install the application on an Amazon EMR cluster. Use Hadoop Distributed File System (HDFS) with General Purpose SSD (gp3) Amazon Elastic Block Store (Amazon EBS) volumes.
  C. Use Amazon FSx for Lustre as shared storage across the EC2 instances that run the application.
  D. Host the application on EC2 instances that have SSD instance store volumes and General Purpose SSD (gp3) Amazon Elastic Block Store (Amazon EBS) volumes attached.
  A. Host the application on EC2 instances that have Provisioned IOPS SSD (io2) Block Express Amazon Elastic Block Store (Amazon EBS) volumes attached.

  Explanation

  Amazon EBS io2 Block Express volumes are designed to deliver sub-millisecond latency and up to 256,000 IOPS per volume, with durability and high availability. This makes io2 Block Express the recommended choice for workloads requiring very high and predictable IOPS, such as enterprise databases and high-transaction-rate applications.

• Question 1036:

  A company runs a latency-sensitive gaming service in the AWS Cloud. The gaming service runs on a fleet of Amazon EC2 instances behind an Application Load Balancer (ALB). An Amazon DynamoDB table stores the gaming data. All the infrastructure is in a single AWS Region. The main user base is in that same Region.

  A solutions architect needs to update the architecture to support a global expansion of the gaming service.

  The gaming service must operate with the least possible latency.

  Which solution will meet these requirements?

  A. Create an Amazon CloudFront distribution in front of the ALB.
  B. Deploy an Amazon API Gateway regional API endpoint. Integrate the API endpoint with the ALB.
  C. Create an accelerator in AWS Global Accelerator. Add a listener. Configure the endpoint to point to the ALB.
  D. Deploy the ALB and the fleet of EC2 instances to another Region. Use Amazon Route 53 with geolocation routing.
  C. Create an accelerator in AWS Global Accelerator. Add a listener. Configure the endpoint to point to the ALB.

  ---

  Explanation

  For latency-sensitive, globally distributed applications such as online gaming, minimizing network latency between users and application endpoints is critical. AWS Global Accelerator is designed specifically for this purpose. It uses the AWS global network and Anycast IP addresses to route user traffic to the closest healthy endpoint, reducing latency and improving performance for users worldwide.

  Option C is the best solution because Global Accelerator directs traffic over the AWS backbone network instead of the public internet, which significantly reduces jitter and latency. It also provides built-in health checks and automatic failover, improving availability as the service expands globally. Importantly, Global Accelerator works seamlessly with existing Application Load Balancers, allowing the company to enhance performance without redesigning the application stack.

  Option A (CloudFront) is optimized for caching static and cacheable content and is not ideal for real-time, stateful gaming traffic.

  Option B adds unnecessary API abstraction and additional latency.

  Option D introduces regional duplication and DNS-based routing, which is slower to react to network conditions and does not provide the same low-latency routing as Global Accelerator.

  Therefore, C meets the requirement for global expansion with the least possible latency while maintaining a simple and highly performant architecture.

• Question 1037:

  A company is developing an application that uses an Amazon Aurora MySQL database. The company plans to regularly make changes to the MySQL database schema to test new features. The tests must not affect the existing production database.

  When the company finishes testing, a developer needs to replicate the changes to the production database. The solution must cause minimal downtime.

  Which solution will meet these requirements?

  A. Create a new staging Aurora MySQL database cluster based on the existing database. Make the schema changes to the new staging database cluster to test the new features.
  B. Create a read replica based on the existing Aurora MySQL database. Make the schema changes to the read replica. Promote the read replica to primary after successful testing.
  C. Create a blue/green deployment of the Aurora MySQL database. Make schema changes in the staging environment to test new features. Direct traffic from the green environment to the blue environment when testing is complete.
  D. Replicate the Aurora MySQL database to an Amazon DynamoDB table. Make the schema changes to the DynamoDB table to test the new features. Configure the application to use the DynamoDB table when testing is complete.
  C. Create a blue/green deployment of the Aurora MySQL database. Make schema changes in the staging environment to test new features. Direct traffic from the green environment to the blue environment when testing is complete.

  ---

  Explanation

  Aurora blue/green deployments are specifically designed for: Safely testing schema changes and database upgrades in an isolated environment (green) without impacting production (blue).

  Performing a fast, low-downtime switchover once testing is complete and validated.

  In this pattern:

  The blue environment is the current production database.

  The green environment is a synchronized copy used for testing changes.

  You apply schema changes to the green environment, run tests, and when ready, perform a managed switchover that minimizes downtime and risk.

  Why others are not ideal:

  Option A: A separate staging cluster allows testing but does not provide automated, low-downtime synchronization and switchover.

  Option B: Aurora read replicas are for read scaling; schema changes on replicas are not supported in the way described, and promotion alone doesn't solve controlled testing and replication of changes.

  Option D: Moving to DynamoDB changes database engines and data models entirely, and does not match the requirement to keep using Aurora MySQL.

• Question 1038:

  A company has stored 10 TB of log files in Apache Parquet format in an Amazon S3 bucket. The company occasionally needs to use SQL to analyze the log files.

  Which solution will meet these requirements MOST cost-effectively?

  A. Create an Amazon Aurora MySQL database. Migrate the data from the S3 bucket into Aurora by using AWS Database Migration Service (AWS DMS). Issue SQL statements to the Aurora database.
  B. Create an Amazon Redshift cluster. Use Redshift Spectrum to run SQL statements directly on the data in the S3 bucket.
  C. Create an AWS Glue crawler to store and retrieve table metadata from the S3 bucket. Use Amazon Athena to run SQL statements directly on the data in the S3 bucket.
  D. Create an Amazon EMR cluster. Use Apache Spark SQL to run SQL statements directly on the data in the S3 bucket.
  C. Create an AWS Glue crawler to store and retrieve table metadata from the S3 bucket. Use Amazon Athena to run SQL statements directly on the data in the S3 bucket.

  A. Generate presigned URLs for the files.
  B. Use cross-Region replication to all Regions.

• Question 1040:

  A company is building an ecommerce web application on AWS. The application sends information about new orders to an Amazon API Gateway REST API to process. The company wants to ensure that orders are processed in the order that they are received.

  Which solution will meet these requirements?

  A. Use an API Gateway integration to publish a message to an Amazon Simple Notification Service (Amazon SNS) topic when the application receives an order. Subscribe an AWS Lambda function to the topic to perform processing.
  B. Use an API Gateway integration to send a message to an Amazon Simple Queue Service (Amazon SQS) FIFO queue when the application receives an order. Configure the SQS FIFO queue to invoke an AWS Lambda function for processing.
  C. Use an API Gateway authorizer to block any requests while the application processes an order.
