Amazon ANS-C01 Exam - Topic 2 Question 18 Discussion

An organization is using a VPC endpoint for Amazon S3. When the security group rules for a set of instances were initially configured, access was restricted to allow traffic only to the IP addresses of the Amazon S3 API endpoints in the region from the published JSON file. The application was working properly, but now is logging a growing number of timeouts when connecting with Amazon S3. No internet gateway is configured for the VPC.Which solution will fix the connectivity failures with the LEAST amount of effort?
B) Update the VPC routing to direct Amazon S3 prefix-list traffic to the VPC endpoint using the route table APIs.
A) Create a Lambda function to update the security group based on AmazonIPSpaceChanged notifications.
C) Update the application server's outbound security group to use the prefix-list for Amazon S3 in the same region.
D) Create an additional VPC endpoint for Amazon S3 in the same route table to scale the concurrent connections to Amazon.

Wait, why would you need an additional VPC endpoint? That seems unnecessary!

I practiced a similar question where we had to deal with VPC endpoints, and I think creating a Lambda function sounds like overkill for this situation.

I remember something about prefix lists being easier to manage than individual IP addresses, so maybe option C is the way to go?

Ah, I see what's going on now. The security group rules are outdated, and we need a way to keep them up-to-date automatically. Option A with the Lambda function seems like the most efficient approach.

Okay, I think I've got it. The issue is that the security group rules are too restrictive, and we need to update the routing to use the VPC endpoint properly. Option B looks like the cleanest solution.

This is a good one. I'm leaning towards option C, since it seems the most straightforward way to update the security group rules without having to deal with the routing or additional VPC endpoints.

Hmm, this looks like it's testing my understanding of how the Deep Security policy settings work. I'll need to carefully read through the options and think about the differences between inherited and explicitly set module states.
