A solutions architect needs to advise a company on how to migrate its on-premises data processing application to the AWS Cloud. Currently, users upload input files through a web portal. The web server then stores the uploaded files on NAS and messages the processing server over a message queue. Each media file can take up to 1 hour to process. The company has determined that the number of media files awaiting processing is significantly higher during business hours, with the number of files rapidly declining after business hours. What is the MOST cost-effective migration recommendation?

A company’s processing team has an AWS account with a production application. The application runs on Amazon EC2 instances behind a Network Load Balancer (NLB). The EC2 instances are hosted in private subnets in a VPC in the eu- west- 1 Region. The VPC was assigned the CIDR block of 10.0.0.0/16. The billing team recently created a new AWS account and deployed an application on EC2 instances that are hosted in private subnets in a VPC in the eu-central-1 Region. The new VPC is assigned the CIDR block of 10.0.0.0/16. The processing application needs to securely communicate with the billing application over a proprietary TCP port.

Question 441

An organization is creating a VPC for their application hosting. The organization has created two private subnets in the same AZ and created one subnet in a separate zone. The organization wants to make a HA system with the internal ELB. Which of these statements is true with respect to an internal ELB in this scenario?

ELB can support only one subnet in each availability zone.

ELB does not allow subnet selection; instead it will automatically select all the available subnets of the VPC.

If the user is creating an internal ELB, he should use only private subnets.

ELB can support all the subnets irrespective of their zones.

Question 443

A company wants to manage the costs associated with a group of 20 applications that are infrequently used, but are still business-critical, by migrating to AWS. The applications are a mix of Java and Node.js spread across different instance clusters. The company wants to minimize costs while standardizing by using a single deployment methodology. Most of the applications are part of month-end processing routines with a small number of concurrent users, but they are occasionally run at other times. Average application memory consumption is less than 1 GB, though some applications use as much as 2.5 GB of memory during peak processing. The most important application in the group is a billing report written in Java that accesses multiple data sources and often for several hours.

Which is the MOST cost-effective solution?

Deploy a separate AWS Lambda function for each application. Use AWS CloudTrail logs and Amazon CloudWatch alarms to verify completion of critical jobs.

Deploy Amazon ECS containers on Amazon EC2 with Auto Scaling configured for memory utilization of 75%. Deploy an ECS task for each application being migrated with ECS task scaling. Monitor services and hosts by using Amazon CloudWatch.

Deploy AWS Elastic Beanstalk for each application with Auto Scaling to ensure that all requests have sufficient resources. Monitor each AWS Elastic Beanstalk deployment by using CloudWatch alarms.

Deploy a new Amazon EC2 instance cluster that co-hosts all applications by using EC2 Auto Scaling and Application Load Balancers. Scale cluster size based on a custom metric set on instance memory utilization. Purchase 3-year Reserved Instance reservations equal to the GroupMaxSize parameter of the Auto Scaling group.

Question 444

A company is designing a data processing platform to process a large number of files in an Amazon S3 bucket and store the results in Amazon DynamoDB. These files will be processed once and must be retained for 1 year. The company wants to ensure that the original files and resulting data are highly available in multiple AWS Regions. Which solution will meet these requirements?

Create an S3 CreateObject event notification to copy the file to Amazon Elastic Block Store (Amazon EBS). Use AWS DataSync to sync the files between EBS volumes in multiple Regions. Use an Amazon EC2 Auto Scaling group in multiple Regions to attach the EBS volumes. Process the files and store the results in a DynamoDB global table in multiple Regions. Configure the S3 bucket with an S3 Lifecycle policy to move the files to S3 Glacier after 1 year.

Create an S3 CreateObject event notification to copy the file to Amazon Elastic File System (Amazon EFS). Use AWS DataSync to sync the files between EFS volumes in multiple Regions. Use an AWS Lambda function to process the EFS files and store the results in a DynamoDB global table in multiple Regions. Configure the S3 buckets with an S3 Lifecycle policy to move the files to S3 Glacier after 1 year.

Copy the files to an S3 bucket in another Region by using cross-Region replication. Create an S3 CreateObject event notification on the original bucket to push S3 file paths into Amazon EventBridge (Amazon CloudWatch Events). Use an AWS Lambda function to poll EventBridge (CloudWatch Events) to process each file and store the results in a DynamoDB table in each Region. Configure both S3 buckets to use the S3 Standard-Infrequent Access (S3 Standard-IA) storage class and an S3 Lifecycle policy to delete the files after 1 year.

Copy the files to an S3 bucket in another Region by using cross-Region replication. Create an S3 CreateObject event notification on the original bucket to execute an AWS Lambda function to process each file and store the results in a DynamoDB global table in multiple Regions. Configure both S3 buckets to use the S3 Standard-Infrequent Access (S3 Standard-IA) storage class and an S3 Lifecycle policy to delete the files after 1 year.

Question 447

A company runs a memory-intensive analytics application using on-demand Amazon EC2 C5 compute optimized instance. The application is used continuously and application demand doubles during working hours. The application currently scales based on CPU usage. When scaling in occurs, a lifecycle hook is used because the instance requires 4 minutes to clean the application state before terminating.

Because users reported poor performance during working hours, scheduled scaling actions were implemented so additional instances would be added during working hours. The Solutions Architect has been asked to reduce the cost of the application.

Which solution is MOST cost-effective?

Use the existing launch configuration that uses C5 instances, and update the application AMI to include the Amazon CloudWatch agent. Change the Auto Scaling policies to scale based on memory utilization. Use Reserved Instances for the number of instances required after working hours, and use Spot Instances to cover the increased demand during working hours.

Update the existing launch configuration to use R5 instances, and update the application AMI to include SSM Agent. Change the Auto Scaling policies to scale based on memory utilization. Use Reserved Instances for the number of instances required after working hours, and use Spot Instances with on-Demand instances to cover the increased demand during working hours.

Use the existing launch configuration that uses C5 instances, and update the application AMI to include SSM Agent. Leave the Auto Scaling policies to scale based on CPU utilization. Use scheduled Reserved Instances for the number of instances required after working hours, and use Spot Instances to cover the increased demand during working hours.

Create a new launch configuration using R5 instances, and update the application AMI to include the Amazon CloudWatch agent. Change the Auto Scaling policies to scale based on memory utilization.
