A company is running several workloads in a single AWS account. A new company policy states that engineers can provision only approved resources and that engineers must use AWS CloudFormation to provision these resources. A solutions architect needs to create a solution to enforce the new restriction on the IAM role that the engineers use for access.

What should the solutions architect do to create the solution?

  1. Upload AWS CloudFormation templates that contain approved resources to an Amazon S3 bucket. Update the IAM policy for the engineers’ IAM role to only allow access to Amazon S3 and AWS CloudFormation. Use AWS CloudFormation templates to provision resources.
  2. Update the IAM policy for the engineers’ IAM role with permissions to only allow provisioning of approved resources and AWS CloudFormation. Use AWS CloudFormation templates to create stacks with approved resources.
  3. Update the IAM policy for the engineers’ IAM role with permissions to only allow AWS CloudFormation actions. Create a new IAM policy with permission to provision approved resources, and assign the policy to a new IAM service role. Assign the IAM service role to AWS CloudFormation during stack creation.
  4. Provision resources in AWS CloudFormation stacks. Update the IAM policy for the engineers’ IAM role to only allow access to their own AWS CloudFormation stack.

Answer(s): C

Explanation:

C) Update the IAM policy for the engineers’ IAM role with permissions to only allow AWS CloudFormation actions. Create a new IAM policy with permission to provision approved resources, and assign the policy to a new IAM service role. Assign the IAM service role to AWS CloudFormation during stack creation.

This solution ensures that engineers can only use AWS CloudFormation to provision resources, while the actual resource provisioning is restricted to only approved resources via the newly created IAM service role. By assigning the service role during stack creation, engineers are limited to using CloudFormation and cannot bypass the resource restrictions. This approach aligns with the company's new policy while ensuring control over resource provisioning.



A solutions architect is designing the data storage and retrieval architecture for a new application that a company will be launching soon. The application is designed to ingest millions of small records per minute from devices all around the world. Each record is less than 4 KB in size and needs to be stored in a durable location where it can be retrieved with low latency. The data is ephemeral and the company is required to store the data for 120 days only, after which the data can be deleted.

The solutions architect calculates that, during the course of a year, the storage requirements would be about 10-15 TB.

Which storage strategy is the MOST cost-effective and meets the design requirements?

  1. Design the application to store each incoming record as a single .csv file in an Amazon S3 bucket to allow for indexed retrieval. Configure a lifecycle policy to delete data older than 120 days.
  2. Design the application to store each incoming record in an Amazon DynamoDB table properly configured for the scale. Configure the DynamoDB Time to Live (TTL) feature to delete records older than 120 days.
  3. Design the application to store each incoming record in a single table in an Amazon RDS MySQL database. Run a nightly cron job that runs a query to delete any records older than 120 days.
  4. Design the application to batch incoming records before writing them to an Amazon S3 bucket. Update the metadata for the object to contain the list of records in the batch and use the Amazon S3 metadata search feature to retrieve the data. Configure a lifecycle policy to delete the data after 120 days.

Answer(s): B

Explanation:

B) Design the application to store each incoming record in an Amazon DynamoDB table properly configured for the scale. Configure the DynamoDB Time to Live (TTL) feature to delete records older than 120 days.

Amazon DynamoDB is highly suitable for storing small records with low latency and high throughput, making it ideal for handling millions of small records per minute. DynamoDB's Time to Live (TTL) feature allows automatic deletion of records older than 120 days, ensuring that the data retention policy is followed without manual intervention. This approach is cost-effective, durable, and scalable to handle the expected data volume and access pattern, meeting both the performance and storage requirements.



A retail company is hosting an ecommerce website on AWS across multiple AWS Regions. The company wants the website to be operational at all times for online purchases. The website stores data in an Amazon RDS for MySQL DB instance.

Which solution will provide the HIGHEST availability for the database?

  1. Configure automated backups on Amazon RDS. In the case of disruption, promote an automated backup to be a standalone DB instance. Direct database traffic to the promoted DB instance. Create a replacement read replica that has the promoted DB instance as its source.
  2. Configure global tables and read replicas on Amazon RDS. Activate the cross-Region scope. In the case of disruption, use AWS Lambda to copy the read replicas from one Region to another Region.
  3. Configure global tables and automated backups on Amazon RDS. In the case of disruption, use AWS Lambda to copy the read replicas from one Region to another Region.
  4. Configure read replicas on Amazon RDS. In the case of disruption, promote a cross-Region and read replica to be a standalone DB instance. Direct database traffic to the promoted DB instance. Create a replacement read replica that has the promoted DB instance as its source.

Answer(s): D

Explanation:

D) Configure read replicas on Amazon RDS. In the case of disruption, promote a cross-Region read replica to be a standalone DB instance. Direct database traffic to the promoted DB instance. Create a replacement read replica that has the promoted DB instance as its source.

This solution provides high availability and disaster recovery by using cross-Region read replicas. In the event of a disruption, a cross-Region read replica can be promoted to a standalone DB instance, ensuring minimal downtime and data loss. This approach ensures that the ecommerce website remains operational in multiple Regions, providing the highest availability for the database, with the ability to quickly restore normal operations by creating a new read replica from the promoted instance.



Example Corp. has an on-premises data center and a VPC named VPC A in the Example Corp. AWS account. The on-premises network connects to VPC A through an AWS Site-To-Site VPN. The on-premises servers can properly access VPC A. Example Corp. just acquired AnyCompany, which has a VPC named VPC B. There is no IP address overlap among these networks. Example Corp. has peered VPC A and VPC B.

Example Corp. wants to connect from its on-premise servers to VPC B. Example Corp. has properly set up the network ACL and security groups.

Which solution will meet this requirement with the LEAST operational effort?

  1. Create a transit gateway. Attach the Site-to-Site VPN, VPC A, and VPC B to the transit gateway. Update the transit gateway route tables for all networks to add IP range routes for all other networks.
  2. Create a transit gateway. Create a Site-to-Site VPN connection between the on-premises network and VPC B, and connect the VPN connection to the transit gateway. Add a route to direct traffic to the peered VPCs, and add an authorization rule to give clients access to the VPCs A and
  3. Update the route tables for the Site-to-Site VPN and both VPCs for all three networks. Configure BGP propagation for all three networks. Wait for up to 5 minutes for BGP propagation to finish.
  4. Modify the Site-to-Site VPN’s virtual private gateway definition to include VPC A and VPC B. Split the two routers of the virtual private getaway between the two VPCs.

Answer(s): A

Explanation:

A) Create a transit gateway. Attach the Site-to-Site VPN, VPC A, and VPC B to the transit gateway. Update the transit gateway route tables for all networks to add IP range routes for all other networks.

This solution meets the requirement with the least operational effort because an AWS Transit Gateway simplifies network management by acting as a hub to interconnect multiple VPCs and VPN connections. By attaching the Site-to-Site VPN, VPC A, and VPC B to the transit gateway, Example Corp can route traffic between all three networks seamlessly. This setup eliminates the need for complex routing and network peering configuration changes across multiple VPCs. It is scalable and reduces operational complexity.
