A global delivery company is modernizing its fleet management system. The company has several business units. Each business unit designs and maintains applications that are hosted in its own AWS account in separate application VPCs in the same AWS Region. Each business unit's applications are designed to get data from a central shared services VPC.
The company wants the network connectivity architecture to provide granular security controls. The architecture also must be able to scale as more business units consume data from the central shared services VPC in the future.
Which solution will meet these requirements in the MOST secure manner?
A company's VPC has Amazon EC2 instances that are communicating with AWS services over the public internet. The company needs to change the connectivity so that the communication
does not occur over the public intemet.
The company deploys AWS PrivateLink endpoints in the VPC. After the deployment of the PrivateLink endpoints, the EC2 instances can no longer communicate at all with the required AWS
services.
Which combination of steps should a network engineer take to restore communicationwith the AWS services? (Select TWO.)
An IoT company sells hardware sensor modules that periodically send out temperature, humidity, pressure, and location data through the MQTT messaging protocol. The hardware sensor modules send this data to the company's on-premises MQTT brokers that run on Linux servers behind a load balancer. The hardware sensor modules have been hardcoded with public IP addresses to reach the brokers.
The company is growing and is acquiring customers across the world. The existing solution can no longer scale and is introducing additional latency because of the company's global presence. As a result, the company decides to migrate its entire infrastructure from on premises to the AWS Cloud. The company needs to migrate without reconfiguring the hardware sensor modules that are already deployed across the world. The solution also must minimize latency.
The company migrates the MQTT brokers to run on Amazon EC2 instances.
What should the company do next to meet these requirements?
