Amazon Exam ANS-C01 Topic 3 Question 28 Discussion

Actual exam question for Amazon's ANS-C01 exam

Question #: 28
Topic #: 3

A company needs to manage Amazon EC2 instances through command line interfaces for Linux hosts and Windows hosts. The EC2 instances are deployed in an environment in which there is

no route to the internet. The company must implement role-based access control for management of the instances. The company has a standalone on-premises environment.

Which approach will meet these requirements with the LEAST maintenance overhead?

ASet up an AWS Direct Connect connection between the on-premises environment and the VPC where the instances are deployed. Configure routing, security groups, and ACLs.
Connect to the instances by using the Direct Connect connection.

BDeploy and configure AWS Systems Manager Agent (SSM Agent) on each instance. Deploy VPC endpoints for Systems Manager Session Manager. Connect to the instances by
using Session Manager.

CEstablish an AWS Site-to-Site VPN connection between the on-premises environment and the VPC where the instances are deployed. Configure routing, security groups, and
ACLs. Connect to the instances by using the Site-to-Site VPN connection.

DDeploy an appliance to the VPC where the instances are deployed. Assign a public IP address to the appliance. Configure security groups and ACLs. Connect to the instances by
using the appliance as an intermediary.

Show Suggested Answer

Suggested Answer: B

The correct approach is to use AWS Systems Manager Session Manager, which allows you to manage your EC2 instances through a secure and browser-based interface. By deploying and configuring SSM Agent on each instance, you can enable Session Manager to communicate with the instances. By deploying VPC endpoints for Session Manager, you can enable the instances to connect to the AWS service without requiring an internet gateway, NAT device, or VPN connection. You can also use IAM policies and SSM documents to implement role-based access control for managing the instances. This approach has the least maintenance overhead, as it does not require any additional infrastructure or configuration.

I don't know, I'm kind of leaning towards C. Site-to-Site VPN might be a bit more work, but it seems more secure than using an intermediary appliance.

Haha, D is just asking for trouble. Exposing an appliance to the public internet? No thank you, I'll pass on that one.

Agreed, B is the best choice here. Maintaining the AWS Direct Connect or VPN connection would be a headache in an environment with no internet access.
