A company hosts a web-based application on AWS in a departmental level VPC. The company has used AWS CloudFormation stacks to provision all the required resources in the AWS Cloud. The company needs to migrate this application to the company level VPC. The application and network components need to be managed as separate entities. Before the company implements changes, the company wants to understand how the changes will affect resources that are already running.
Which combination of actions should a solutions architect take to meet these requirements? (Choose two.)
  • A. Perform drift detection on the CloudFormation stacks to track the changes.
  • B. Enable AWS Config to track the changes to the CloudFormation stacks.
  • C. Create change sets before updating the CloudFormation stacks.
  • D. Create a CloudFormation root stack that has two nested stacks: one stack for the application layer and one stack for the network layer.
  • E. Create a CloudFormation cross-stack reference. Export company level VPC stack outputs. Import the stack outputs into the application stack.

Which combination of steps will meet these requirements MOST cost-effectively? (Choose two.)
  • A. Create an S3 bucket policy that denies the s3:DeleteObject action.

  • C. Upload the messages to Amazon S3. Use S3 Object Lock in governance mode.
  • D. Upload the messages to Amazon S3. Use S3 Object Lock in compliance mode.
  • E. Use S3 Inventory. Create an AWS Batch job that periodically scans the inventory and deletes the messages after 12 months.

A company is deploying an application that processes streaming data in near-real time. The company plans to use Amazon EC2 instances for the workload. The network architecture must be configurable to provide the lowest possible latency between nodes.
Which combination of network solutions will meet these requirements? (Choose two.)
  • A. Place the EC2 instances in multiple VPCs, and configure VPC peering.
  • B. Run the EC2 instances in a spread placement group.
  • C. Attach an Elastic Fabric Adapter (EFA) to each EC2 instance.
  • D. Use Amazon Elastic Block Store (Amazon EBS) optimized instance types.

A company hosts its enterprise content management platform in one AWS Region but needs to operate the platform across multiple Regions. The company has an Amazon Elastic Kubernetes Service (Amazon EKS) cluster that runs its microservices. The EKS cluster stores and retrieves objects from Amazon S3. The EKS cluster also stores and retrieves metadata from Amazon DynamoDB.
Which combination of steps should a solutions architect take to deploy the platform across multiple Regions? (Choose two.)
  • A. Replicate the EKS cluster with cross-Region replication.
  • B. Use Amazon API Gateway to create a global endpoint to the EKS cluster.
  • C. Use AWS Global Accelerator endpoints to distribute the traffic to multiple Regions.
  • D. Use Amazon S3 access points to give access to the objects across multiple Regions. Configure DynamoDB Accelerator (DAX). Connect DAX to the relevant tables.
  • E. Deploy an EKS cluster and an S3 bucket in another Region. Configure cross-Region replication on both S3 buckets. Turn on global tables for DynamoDB.

A company runs a three-tier web application in a VPC across multiple Availability Zones. Amazon EC2 instances run in an Auto Scaling group for the application tier.
The company needs to make an automated scaling plan that will analyze each resource's daily and weekly historical workload trends. The configuration must scale resources appropriately according to both the forecast and live changes in utilization.
Which scaling strategy should a solutions architect recommend to meet these requirements?
  • A. Implement dynamic scaling with step scaling based on average CPU utilization from the EC2 instances.
  • B. Enable predictive scaling to forecast and scale. Configure dynamic scaling with target tracking.
  • C. Create an automated scheduled scaling action based on the traffic patterns of the web application.
  • D. Set up a simple scaling policy. Increase the cooldown period based on the EC2 instance startup time.

A trucking company is deploying an application that will track the GPS coordinates of all the company's trucks. The company needs a solution that will generate real-time statistics based on metadata lookups with high read throughput and microsecond latency. The database must be fault tolerant and must minimize operational overhead and development effort.
Which combination of steps should a solutions architect take to meet these requirements? (Choose two.)
  • A. Use Amazon DynamoDB as the database.
  • B. Use Amazon Aurora MySQL as the database.
  • C. Use Amazon RDS for MySQL as the database
  • D. Use Amazon ElastiCache as the caching layer.
  • E. Use Amazon DynamoDB Accelerator (DAX) as the caching layer.

A company serves its website by using an Auto Scaling group of Amazon EC2 instances in a single AWS Region. The website does not require a database.
The company is expanding, and the company's engineering team deploys the website to a second Region. The company wants to distribute traffic across both
Regions to accommodate growth and for disaster recovery purposes. The solution should not serve traffic from a Region in which the website is unhealthy.
Which policy or resource should the company use to meet these requirements?
  • A. An Amazon Route 53 simple routing policy
  • B. An Amazon Route 53 multivalue answer routing policy
  • C. An Application Load Balancer in one Region with a target group that specifies the EC2 instance IDs from both Regions
  • D. An Application Load Balancer in one Region with a target group that specifies the IP addresses of the EC2 instances from both Regions

  • A. The ELB is not configured with a proper health check.
  • B. The route tables in the VPC are configured incorrectly.
  • C. The EC2 instances are not associated with an Elastic IP address.
  • D. The security group attached to the NAT gateway is configured incorrectly.
  • E. The outbound rules on the security group attached to the EC2 instances are configured incorrectly.
