1. A solutions architect is designing the cloud architecture for a new application being deployed on AWS. The process should run in parallel while adding and removing application nodes as needed based on the number of jobs to be processed. The processor application is stateless. The solutions architect must ensure that the application is loosely coupled and the job items are durably stored.Which design should the solutions architect use?

A) Create an Amazon SNS topic to send the jobs that need to be processed. Create an Amazon Machine Image (AMI) that consists of the processor application. Create a launch template that uses the AMI. Create an Auto Scaling group using the launch template. Set the scaling policy for the Auto Scaling group to add and remove nodes based on the number of messages published to the SNS topic.
B) Create an Amazon SNS topic to send the jobs that need to be processed. Create an Amazon Machine Image (AMI) that consists of the processor application. Create a launch configuration that uses the AMI. Create an Auto Scaling group using the launch configuration. Set the scaling policy for the Auto Scaling group to add and remove nodes based on CPU usage.
C) Create an Amazon SQS queue to hold the jobs that need to be processed. Create an Amazon Machine Image (AMI) that consists of the processor application. Create a launch template that uses the AMI. Create an Auto Scaling group using the launch template. Set the scaling policy for the Auto Scaling group to add and remove nodes based on the number of items in the SQS queue.
D) Create an Amazon SQS queue to hold the jobs that need to be processed. Create an Amazon Machine Image (AMI) that consists of the processor application. Create a launch configuration that uses the AMI. Create an Auto Scaling group using the launch configuration. Set the scaling policy for the Auto Scaling group to add and remove nodes based on network usage.



2. A company is migrating from an on-premises infrastructure to the AWS Cloud. One of the company's application stores files a Windows file server farm that uses Distribute File System Replication (DFSR) to keep data in sync. A solutions architect needs to replace the file server farm.Which service should the solutions architect use?

A) Amazon EFS
B) AWS Storage Gateway
C) Amazon S3
D) Amazon FSx



3. A solutions architect is designing an application for a two-step order process. The first step is synchronous and must return to the user with little latency. The second step takes longer, so it will be implemented in a separate component. Orders must be processed exactly once and in the order in which they are received.How should the solutions architect integrate these components?

A) Use Amazon SQS FIFO queues
B) Create an SNS topic and subscribe an Amazon SQS Standard queue to that topic
C) Use an AWS Lambda function along with Amazon SQS standard queues
D) Create an SNS topic and subscribe an Amazon SQS FIFO queue to that topic



4. A company has a legacy application that processes data in two parts. The second part of the process takes longer than the list, so the company has decided to rewrite the application as two microservices running on Amazon ECS that can scale independently..How should a solutions architect integrate the microservices?

A) Implement code in microservice 1 to publish data to an Amazon SNS topic. Implement code in microservice 2 to subscribe to this topic.
B) Implement code in microservice 1 to send data to Amazon Kinesis Data Firehose. Implement code in microservice 2 to read from Kinesis Data Firehose.
C) Implement code in microservice 1 to send data to an Amazon SQS queue. Implement code in microservice 2 to process messages from the queue.
D) Implement code in microservice 1 to send data to an Amazon S3 bucket Use S3 event notifications to invoke microservice 2.



5. A media streaming company collects real-time data and stores it in a disk-optimized database system. The company is not getting the expected throughput and wants an in-memory database storage solution that performs faster and provides high availability using data replication.Which database should a solutions architect recommend?

A) Amazon RDS for MySQL
B) Amazon ElastiCache for Redis
C) Amazon RDS for PostgreSQL
D) Amazon ElastiCache for Memcached
