QUESTION: 33

A company has created an OU in AWS Organizations for each of its engineering teams. Each OU owns multiple AWS accounts. The organization has hundreds of AWS accounts.

A solutions architect must design a solution so that each OU can view a breakdown of usage costs across its AWS accounts.

Which solution meets these requirements?

Create an AWS Cost and Usage Report (CUR) for each OU by using AWS Resource Access Manager. Allow each team to visualize the CUR through an Amazon QuickSight dashboard.
Create an AWS Cost and Usage Report (CUR) from the AWS Organizations management account. Allow each team to visualize the CUR through an Amazon QuickSight dashboard.
Create an AWS Cost and Usage Report (CUR) in each AWS Organizations member account. Allow each team to visualize the CUR through an Amazon QuickSight dashboard.
Create an AWS Cost and Usage Report (CUR) by using AWS Systems Manager. Allow each team to visualize the CUR through Systems Manager OpsCenter dashboards.

Answer(s): B

Explanation:

B) Create an AWS Cost and Usage Report (CUR) from the AWS Organizations management account. Allow each team to visualize the CUR through an Amazon QuickSight dashboard is the correct solution because AWS Cost and Usage Reports (CURs) can be generated from the management account of AWS Organizations. By centralizing this reporting in the management account, it allows for a comprehensive view of usage across all OUs and accounts within the organization. Amazon QuickSight can then be used to visualize this data, enabling each team to see their breakdown of costs in a user-friendly dashboard. This approach avoids the complexity of managing multiple CURs and offers the most straightforward and scalable solution.

QUESTION: 34

A company is storing data on premises on a Windows file server. The company produces 5 GB of new data daily.

The company migrated part of its Windows-based workload to AWS and needs the data to be available on a file system in the cloud. The company already has established an AWS Direct Connect connection between the on-premises network and AWS.

Which data migration strategy should the company use?

Use the file gateway option in AWS Storage Gateway to replace the existing Windows file server, and point the existing file share to the new file gateway.
Use AWS DataSync to schedule a daily task to replicate data between the on-premises Windows file server and Amazon FSx.
Use AWS Data Pipeline to schedule a daily task to replicate data between the on-premises Windows file server and Amazon Elastic File System (Amazon EFS).
Use AWS DataSync to schedule a daily task to replicate data between the on-premises Windows file server and Amazon Elastic File System (Amazon EFS).

Answer(s): B

Explanation:

B) Use AWS DataSync to schedule a daily task to replicate data between the on-premises Windows file server and Amazon FSx is the correct answer. AWS DataSync is designed to automate the migration of data between on-premises systems and AWS, making it ideal for this scenario. The company already has a Direct Connect connection, and Amazon FSx provides a fully managed Windows-native file system. DataSync can be scheduled to handle the daily replication of the 5 GB of new data from the on-premises server to Amazon FSx with minimal operational overhead.

QUESTION: 35

A company’s solutions architect is reviewing a web application that runs on AWS. The application references static assets in an Amazon S3 bucket in the us-east-1 Region. The company needs resiliency across multiple AWS Regions. The company already has created an S3 bucket in a second Region.

Which solution will meet these requirements with the LEAST operational overhead?

Configure the application to write each object to both S3 buckets. Set up an Amazon Route 53 public hosted zone with a record set by using a weighted routing policy for each S3 bucket. Configure the application to reference the objects by using the Route 53 DNS name.
Create an AWS Lambda function to copy objects from the S3 bucket in us-east-1 to the S3 bucket in the second Region. Invoke the Lambda function each time an object is written to the S3 bucket in us-east-1. Set up an Amazon CloudFront distribution with an origin group that contains the two S3 buckets as origins.
Configure replication on the S3 bucket in us-east-1 to replicate objects to the S3 bucket in the second Region. Set up an Amazon CloudFront distribution with an origin group that contains the two S3 buckets as origins.
Configure replication on the S3 bucket in us-east-1 to replicate objects to the S3 bucket in the second Region. If failover is required, update the application code to load S3 objects from the S3 bucket in the second Region.

Answer(s): C

Explanation:

C) Configure replication on the S3 bucket in us-east-1 to replicate objects to the S3 bucket in the second Region. Set up an Amazon CloudFront distribution with an origin group that contains the two S3 buckets as origins is the correct answer because it provides resiliency across multiple Regions with minimal operational overhead. S3 replication ensures that objects are automatically copied from one Region to another, and Amazon CloudFront's origin group allows for automatic failover between the two S3 buckets. This approach ensures high availability and resilience for the web application while requiring minimal manual intervention.

QUESTION: 36

A company is hosting a three-tier web application in an on-premises environment. Due to a recent surge in traffic that resulted in downtime and a significant financial impact, company management has ordered that the application be moved to AWS. The application is written in .NET and has a dependency on a MySQL database. A solutions architect must design a scalable and highly available solution to meet the demand of 200,000 daily users.

Which steps should the solutions architect take to design an appropriate solution?

Use AWS Elastic Beanstalk to create a new application with a web server environment and an Amazon RDS MySQL Multi-AZ DB instance. The environment should launch a Network Load Balancer (NLB) in front of an Amazon EC2 Auto Scaling group in multiple Availability Zones. Use an Amazon Route 53 alias record to route traffic from the company’s domain to the NLB.
Use AWS CloudFormation to launch a stack containing an Application Load Balancer (ALB) in front of an Amazon EC2 Auto Scaling group spanning three Availability Zones. The stack should launch a Multi-AZ deployment of an Amazon Aurora MySQL DB cluster with a Retain deletion policy. Use an Amazon Route 53 alias record to route traffic from the company’s domain to the AL
Use AWS Elastic Beanstalk to create an automatically scaling web server environment that spans two separate Regions with an Application Load Balancer (ALB) in each Region. Create a Multi-AZ deployment of an Amazon Aurora MySQL DB cluster with a cross-Region read replica. Use Amazon Route 53 with a geoproximity routing policy to route traffic between the two Regions.
Use AWS CloudFormation to launch a stack containing an Application Load Balancer (ALB) in front of an Amazon ECS cluster of Spot instances spanning three Availability Zones. The stack should launch an Amazon RDS MySQL DB instance with a Snapshot deletion policy. Use an Amazon Route 53 alias record to route traffic from the company’s domain to the ALB.

Answer(s): B

Explanation:

B) Use AWS CloudFormation to launch a stack containing an Application Load Balancer (ALB) in front of an Amazon EC2 Auto Scaling group spanning three Availability Zones. The stack should launch a Multi-AZ deployment of an Amazon Aurora MySQL DB cluster with a Retain deletion policy. Use an Amazon Route 53 alias record to route traffic from the company’s domain to the ALB is the correct solution because it provides a scalable and highly available architecture with minimal downtime risk. The Auto Scaling group and Application Load Balancer ensure the web application can handle variable traffic loads, while Amazon Aurora MySQL provides high availability and performance with Multi-AZ deployment. Using AWS CloudFormation helps automate the setup and configuration, and Route 53 ensures smooth routing of traffic to the application.
