Question 37
A company operates pipelines across North America and South America. The company assesses pipeline inspection gauges with imagery and ultrasonic sensor data to monitor the condition of its pipelines. The pipelines are in areas with intermittent or unavailable internet connectivity. The imager data at each site requires terabytes of storage each month. The company wants a solution to collect the data at each site in monthly intervals and to store the data with high durability.

Question 39
A company has decided to move some workloads onto AWS to create a grid environment to run market analytics. The grid will consist of many similar instances, spun-up by a job-scheduling function. Each time a large analytics workload is completed, a new VPC is deployed along with job scheduler and grid nodes.
Multiple grids could be running in parallel.
Key requirements are:
* Grid instances must communicate with Amazon S3 retrieve data to be processed.
* Grid instances must communicate with Amazon DynamoDB to track intermediate data,
* The job scheduler need only to communicate with the Amazon EC2 API to start new grid nodes.
A key requirement is that the environment has no access to the internet, either directly or via the on-premises proxy. However, the application needs to be able to seamlessly communicate to Amazon S3, Amazon DynamoDB, and Amazon EC2 API, without the need for reconfiguration for each new deployment.
Which of the following should the Solutions Architect do to achieve this target architecture? (Choose three.)
