How should a solutions architect design a messaging solution using Amazon SQS and Amazon SNS for an online marketplace application with multiple microservices?

Single Choice

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 OrderCancelation 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?

Create a single SQS queue and publish order events to it. The Email OrderProcessing and Order Cancellation microservices can then consume messages of the queue.

Create three SNS topics for each microservice. Publish order events to the three topics. Subscribe each of the Email OrderProcessing and Order Cancellation microservices to its own topic.

Create an SNS topic and publish order events to it. Create three SQS queues for the Email OrderProcessing and Order Cancellation microservices. Subscribe all SQS queues to the SNS topic with message filtering.

Create two SQS queues and publish order events to both queues simultaneously. One queue is for the Email and OrderProcessing microservices. The second queue is for the Email and Order Cancellation microservices.

How can a solutions architect reduce the operational burden of building a scalable key management infrastructure?

Single Choice

A company wants to build a scalable key management infrastructure to support developers who need to encrypt data in their applications.

What should a solutions architect do to reduce the operational burden?

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.

What AWS Service Provides a Managed, High-Throughput Shared File System for Windows?

Single Choice

A company wants to deploy a shared file system for its .NET application servers and Microsoft SQL Server databases running on Amazon EC2 instances with Windows Server 2016. The solution must be able to be integrated into the corporate Active Directory domain, be highly durable, be managed by AWS, and provide high levels of throughput and IOPS.

Which solution meets these requirements?

Use Amazon Elastic File System (Amazon EFS).

Use AWS Storage Gateway in file gateway mode.

Use Amazon FSx for Windows File Server.

Deploy a Windows file server on two On Demand instances across two Availability Zones.

What is the solution with the least operational overhead for enforcing strict security guidelines on accessing AWS Cloud resources?

Single Choice

A company wants to enforce strict security guidelines on accessing AWS Cloud resources as the company migrates production workloads from its data centers. Company management wants all users to receive permissions according to their job roles and functions.

Which solution meets these requirements with the LEAST operational overhead?

Create an AWS Single Sign-On deployment. Connect to the on-premises Active Directory to centrally manage users and permissions across the company.

Create an IAM role for each job function. Require each employee to call the sts:AssumeRole action in the AWS Management Console to perform their job role.

Create individual IAM user accounts for each employee. Create an IAM policy for each job function, and attach the policy to all IAM users based on their job role.

Create individual IAM user accounts for each employee. Create IAM policies for each job function. Create IAM groups, and attach associated policies to each group. Assign the IAM users to a group based on their job role.

How can a solutions architect optimize performance and minimize latency for a scalable web application on AWS?

Single Choice

A company wants to host a scalable web application on AWS. The application will be accessed by users from different geographic regions of the world. Application users will be able to download and upload unique data up to gigabytes in size. The development team wants a cost-effective solution to minimize upload and download latency and maximize performance.

What should a solutions architect do to accomplish this?

Use Amazon S3 with Transfer Acceleration to host the application.

Use Amazon S3 with CacheControl headers to host the application.

Use Amazon EC2 with Auto Scaling and Amazon CloudFront to host the application.

Use Amazon EC2 with Auto Scaling and Amazon ElastiCache to host the application.

What is the recommended solution for hosting a highly available web application on AWS with VPC communication to a database?

Single Choice

A company wants to host a web application on AWS that will communicate to a database within a VPC. The application should be highly available.

What should a solutions architect recommend?

Create two Amazon EC2 instances to host the web servers behind a load balancer, and then deploy the database on a large instance.

Deploy a load balancer in multiple Availability Zones with an Auto Scaling group for the web servers, and then deploy Amazon RDS in multiple Availability Zones.

Deploy a load balancer in the public subnet with an Auto Scaling group for the web servers, and then deploy the database on an Amazon EC2 instance in the private subnet.

Deploy two web servers with an Auto Scaling group, configure a domain that points to the two web servers, and then deploy a database architecture in multiple Availability Zones.

How can a solutions architect route client requests to specific AWS Regions for hosting web application content?

Single Choice

A company wants to host its web application on AWS using multiple Amazon EC2 instances across different AWS Regions. Since the application content will be specific to each geographic region, the client requests need to be routed to the server that hosts the content for that clients Region.

What should a solutions architect do to accomplish this?

Configure Amazon Route 53 with a weighted routing policy.

Configure Amazon Route 53 with a geolocation routing policy.

Configure Amazon Route 53 with a latency routing policy.

Configure Amazon Route 53 with a multivalue answer routing policy
