Prerequisite for Using AWS OpsWorks to Manage Applications on Customer Data Centers

Correct Answer - D.

It is given in the AWS documentation that: You can use AWS OpsWorks Stacks to configure and manage both Linux and Windows EC2 instances.

But there is no need for EC2 instance, the question focuses on compute servers on the data centres means outside of AWS.

A VPC endpoint enables private connections between your VPC and supported AWS services and VPC endpoint services powered by AWS PrivateLink.

VPC endpoints are virtual devices.

To use AWS OpsWorks for servers in customer data centres, the servers should have Linux operating systems with an OpsWorks Stacks agent installed and connectivity to AWS Public endpoints.

Using AWS OpsWorks Stacks to create Amazon EC2 instances, you can also register instances with a Linux stack that were created outside of AWS OpsWorks Stacks.

However, they must be running one of the supported Linux distributions.

You cannot register Amazon EC2 or on-premises Windows instances.

Option A is incorrect because servers deployed at customer data centres only supports Linux OS, not both.

Option B is incorrect because servers deployed at customer data centres should have connectivity to AWS public endpoints instead of private endpoints.

Options C is incorrect because on-premise servers should have Linux OS instead of Windows OS.

AWS OpsWorks is a configuration management service that provides managed instances of Chef and Puppet, which are automation platforms that help you automate infrastructure tasks, deploy applications, and manage servers. With AWS OpsWorks, you can use Chef and Puppet to automate how servers are configured, deployed, and managed across your Amazon EC2 instances or your on-premises compute servers.

To manage applications on servers at the customer data centres (on-premises compute servers) using AWS OpsWorks, the servers should meet the following prerequisites:

• The servers should be running either Linux or Windows OS.
• The servers should have connectivity to AWS endpoints.

Option A states that the servers should be running on either Linux or Windows OS with connectivity to AWS public endpoints. This option is incorrect because it mentions AWS public endpoints, which are internet-facing endpoints used for accessing AWS services from the internet. On-premises compute servers do not typically have direct connectivity to AWS public endpoints, and they usually require a VPN or Direct Connect connection to AWS.

Option B states that the servers should be running Linux OS with connectivity to AWS private endpoints. This option is incorrect because it mentions AWS private endpoints, which are used to access AWS services over a private connection rather than the internet. Private endpoints are typically used for accessing AWS services from within a VPC, and they are not relevant to on-premises compute servers.

Option C states that the servers should be running Windows OS with connectivity to AWS private endpoints. This option is incorrect for the same reasons as option B.

Option D states that the servers should be running Linux OS with connectivity to AWS public endpoints. This option is incorrect because it mentions AWS public endpoints, which are not typically accessible from on-premises compute servers.

Therefore, the correct answer is A. Servers should be running on either Linux or Windows OS with connectivity to AWS public endpoints.
