On AWS, a business want to develop an online marketplace application as a collection of loosely linked microservices. When a client places a new order, two microservices should process the event concurrently in this application. A confirmation email will be sent via the Email microservice, and the OrderProcessing microservice will initiate the order delivery procedure. When a client cancels an order, the OrderCancellation and Email microservices should process the cancellation concurrently. A solutions architect want to build the communications between microservices using Amazon Simple Queue Service (Amazon SQS) and Amazon Simple Notification Service (Amazon SNS). What approach should the solutions architect use while designing the solution? Create a single SQS queue and publish order events to it.

Configure Amazon CloudFront to deliver HTTPS content using the EC2 instances as the origin.
A new AWS customer creates a Site-to-Site VPN between its on-premises datacenter and AWS. According to the firm's security policy, traffic originating on-premises shall remain inside the private IP space of the company while talking with an Amazon Elastic Container Service (Amazon ECS) cluster containing a sample web application. Which solution satisfies this criterion? Configure a gateway endpoint for Amazon ECS. Modify the route table to include an entry pointing to the ECS cluster. Create a Network Load Balancer and AWS PrivateLink endpoint for Amazon ECS in the same VPC that is hosting the ECS cluster. Create a Network Load Balancer in one VPC and an AWS PrivateLink endpoint for Amazon ECS in another VPC. Connect the two VPCs by using VPC peering. Configure an Amazon Route 53 record with Amazon ECS as the target. Apply a server certificate to Route 53 from AWS Certificate Manager (ACM) for SSL offloading.
A firm that hosts its web application on Amazon Web Services (AWS) needs to verify that all Amazon EC2 instances, Amazon RDS database instances, and Amazon Redshift clusters are tagged. The organization wishes to reduce the time and effort required to configure and operate this check. What actions should a solutions architect take to achieve this? Use AWS Config rules to define and detect resources that are not properly tagged. Use Cost Explorer to display resources that are not properly tagged. Tag those resources manually. Write API calls to check all resources for proper tag allocation. Periodically run the code on an EC2 instance. Write API calls to check all resources for proper tag allocation. Schedule an AWS Lambda function through Amazon CloudWatch to periodically run the code.
A business depends on an application that requires at least four Amazon EC2 instances for normal traffic and up to twelve EC2 instances for peak loads. The application is mission-critical to the company and must maintain a high level of availability. Which solution will satisfy these criteria? Deploy the EC2 instances in an Auto Scaling group. Set the minimum to 4 and the maximum to 12, with 2 in Availability Zone A and 2 in Availability Zone B. Deploy the EC2 instances in an Auto Scaling group. Set the minimum to 4 and the maximum to 12, with all 4 in Availability Zone A. Deploy the EC2 instances in an Auto Scaling group. Set the minimum to 8 and the maximum to 12, with 4 in Availability Zone A and 4 in Availability Zone B. Deploy the EC2 instances in an Auto Scaling group. Set the minimum to 8 and the maximum to 12, with all 8 in Availability Zone A.
A business seeks to construct a scalable key management infrastructure to assist developers in encrypting data inside their apps. How might a solutions architect alleviate operational burdens? Use multi-factor authentication (MFA) to protect the encryption keys. Use AWS Key Management Service (AWS KMS) to protect the encryption keys. Use AWS Certificate Manager (ACM) to create, store, and assign the encryption keys. Use an IAM policy to limit the scope of users who have access permissions to protect the encryption keys.
A solutions architect is entrusted with the responsibility of moving 750 TB of data from an on-premises network-attached file system to an Amazon S3 Glacier at a branch office. The migration must not exceed the 1 Mbps internet connection on-premises. Which solution will satisfy these criteria? Create an AWS site-to-site VPN tunnel to an Amazon S3 bucket and transfer the files directly. Transfer the files directly by using the AWS CLI. Order 10 AWS Snowball Edge Storage Optimized devices, and select an S3 Glacier vault as the destination. Mount the network-attached file system to an S3 bucket, and copy the files directly. Create a lifecycle policy to transition the S3 objects to Amazon S3 Glacier. Order 10 AWS Snowball Edge Storage Optimized devices, and select an Amazon S3 bucket as the destination. Create a lifecycle policy to transition the S3 objects to Amazon S3 Glacier.
A solutions architect notices that a nightly batch processing operation is automatically scaled up for an additional hour prior to reaching the targeted Amazon EC2 capacity. Every night, the peak capacity is the same, and batch operations always begin at 1 a.m. The solutions architect must create a cost-effective approach that enables rapid attainment of the targeted EC2 capacity while allowing the Auto Scaling group to scale down once the batch processes are complete. What actions should the solutions architect take to ensure that these criteria are met? Increase the minimum capacity for the Auto Scaling group. Increase the maximum capacity for the Auto Scaling group. Configure scheduled scaling to scale up to the desired compute level. Change the scaling policy to add more EC2 instances during each scaling operation.
