Amazon ANS-C01 Exam - 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.

Wait, can you really manage without internet access? That's surprising!

A Direct Connect sounds too complex for this scenario.

Deploying an appliance sounds risky to me. I think option D could introduce more points of failure, especially since we want to keep maintenance low.

I practiced a similar question where we had to choose between VPN and Direct Connect. I feel like option C could work, but it might require more setup than necessary.

I'm not entirely sure, but I think Direct Connect might be overkill for this scenario. It sounds complicated for just managing instances without internet access.

I remember studying about AWS Systems Manager, and it seems like option B could be the best choice since it minimizes maintenance.

I'm a bit confused by the different connectivity options. I'll need to review the details of each one to understand the tradeoffs and determine the best approach for this scenario.

The Direct Connect or Site-to-Site VPN options seem like they could work, but they might require more ongoing maintenance and configuration. The Systems Manager approach sounds like the simplest solution.

Okay, let me think this through. I'm leaning towards the AWS Systems Manager option since it provides a secure way to connect without needing to manage a VPN or other external appliance.

Hmm, not sure about this one. Seems like we need to establish some kind of secure connection to the EC2 instances, but I'm not sure which option would have the least maintenance overhead.

This looks like a classic network connectivity question. I'll need to carefully consider the requirements around no internet access and role-based access control.

Okay, let me see. The question is asking about the multi-planar system design, so I'll need to focus on understanding the different planes and how they're connected.

I'm not too sure about option B being valid just because it says the Employee Name must be required. Isn't that more about validation than just field configuration?

I'm pretty sure the answer is A. The command "app-hosting" is used to enable application hosting on Cisco IOS XE devices.

I remember something about Call Queuing from our practice exam. It could help users wait for available bandwidth, but I'm not sure if it's really the best answer here.

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.
