A company wants to build an online marketplace application on AWS as a set of loosely coupled microservices For this application, when a customer submits a new order two microservices should handle the event simultaneously The Email microservice will send a confirmation email and the OrderProcessing microservice will start the order delivery process If a customer cancels an order, the OrderCancellation and Email microservices should handle the event simultaneously.
A solutions architect wants to use Amazon Simple Queue Service (Amazon SQS) and Amazon Simple Notification Service (Amazon SNS) to design the messaging between the microservices.
How should the solutions architect design the solution?

• A.Create an SNS topic and publish order events to it Create three SQS queues for the Email OrderProcessing and OrderCancellation microservices Subscribe all SQS queues to the SNS topic with message filtering
• B.Create three SNS topics for each microservice Publish order events to the three topics Subscribe each of the Email OrderProcessmg, and OrderCancellation microservices to its own topic
• C.Create two SQS queues and publish order events to both queues simultaneously One queue is for the Email and OrderProcessmg microservices The second queue is for the Email and Order Cancellation microservices
• D.Create a single SOS queue and publish order events to it The Email, OrderProcessing and OrderCancellation microservices can then consume messages off the queue

A company is investigating potential solutions that would collect, process, and store users' service usage data.
The business objective is to create an analytics capability that will enable the company to gather operational insights quickly using standard SQL queries. The solution should be highly available and ensure Atomicity, Consistency, Isolation, and Durability (ACID) compliance in the data tier.
Which solution should a solutions architect recommend?

• A.Deploy PostgreSQL on an Amazon EC2 instance that uses Amazon EBS Throughput Optimized HDD (st1) storage.
• B.Use Amazon DynamoDB transactions
• C.Use a fully managed Amazon RDS for MySQL database in a Multi-AZ design
• D.Create an Amazon Neptune database in a Multi AZ design

A solutions architect is creating a new VPC design. There are two public subnets for the load balancer, two private subnets for web servers, and two private subnets for MySQL. The web servers use only HTTPS. The solutions architect has already created a security group for the load balancer allowing port 443 from 0.0.0.0/0.
Company policy requires that each resource has the least access required to still be able to perform its tasks.
Which additional configuration strategy should the solutions architect use to meet these requirements?

• A.Create a security group for the web servers and allow port 443 from 0.0.0.0/0. Create a security group (or the MySQL servers and allow port 3306 from the web servers security group.
• B.Create a network ACL for the web servers and allow port 443 from the load balancer. Create a network ACL for the MySQL servers and allow port 3306 from the web servers security group.
• C.Create a network ACL for the web servers and allow port 443 from 0.0.0.0/0. Create a network ACL for the MySQL servers and allow port 3306 from the web servers security group.
• D.Create a security group for the web servers and allow port 443 from the load balancer. Create a security group for the MySQL servers and allow port 3306 from the web servers security group.
