Amazon Exam DOP-C01 Topic 2 Question 89 Discussion

Actual exam question for Amazon's DOP-C01 exam

Question #: 89
Topic #: 2

A company's legacy application uses IAM user credentials to access resources in the company's AWS Organizations organization. A DevOps engineer needs to ensure new IAM users cannot be created unless the employee creating the IAM user is on an exception list.

Which solution will meet these requirements?

AAttach an Organizations SCP with an explicit deny for all iam:CreateAccessKey actions with a condition that excludes StringNotEquals for aws:username with a value of the exception list.

BAttach an Organizations SCP with an explicit deny for all iam:CreateUser actions with a condition that includes StringEquals for aws:username with a value of the exception list.

CCreate an Amazon EventBridge (Amazon CloudWatch Events) rule with a pattern that matches the iam:CreateAccessKey action with an AWS Lambda function target. The function will check the user name account against an exception list. If the user is not in the exception list, the function will delete the user.

DCreate an Amazon EventBridge (Amazon CloudWatch Events) rule with a pattern that matches the iam:CreateUser action with an AWS Lambda function target. The function will check the user name and account against an exception list. If the user is not in the exception list, the function will delete the user.

I see your points, but I think option C might work too by using Amazon EventBridge for monitoring and enforcement.

I disagree, I believe option A is better as it specifically denies the creation of access keys, which is more aligned with the requirement.

I think option B is the answer because it explicitly denies IAM user creation for those not on the exception list.

That's a good point, but option C) might also work by using Lambda functions to check the exception list before creating a new user.

I prefer option A) as well, it seems more straightforward and easier to implement.

I disagree, I believe option A) is better because it focuses on denying access key creation which is more critical for security.

I think option B) would be the best solution, it explicitly denies creating new IAM users based on the exception list.

That's a good point. Option A does seem like the most reliable and straightforward solution. It's also more preventative than the EventBridge approach, which could still allow some unauthorized users to be created before they're deleted.

Can we just agree that any solution involving deleting users after the fact is a terrible idea? That's like trying to catch a speeding bullet with your bare hands.

F: Absolutely, it's all about setting up the right policies from the start to avoid unnecessary cleanup tasks later on.

I think Option A is the way to go. By using an SCP with a condition that excludes the exception list, we can effectively block the iam:CreateAccessKey action for all non-authorized users. This way, we don't have to worry about race conditions or other potential issues.

I don't know, guys. Wouldn't Option B be simpler since we only need to worry about creating new users, not access keys? Plus, it's more direct - no need for fancy EventBridge rules or Lambda functions.

In that case, maybe Option A would be more comprehensive. It covers both creating users and access keys.

Option B sounds good to me. We should just deny creating new users for those not in the exception list.

I agree, this is a complex scenario. We need to make sure the solution not only meets the requirements but also doesn't introduce any unintended consequences.

Yeah, those options are way too complicated. Why go through all that trouble when you can just use an SCP to explicitly deny the actions you don't want? I vote for Option A.

Ha! I like how Option C and D try to be sneaky and delete the user after they've been created. Talk about a band-aid on a bullet wound!

I'm not so sure about that. Option B only denies the CreateUser action, but we also need to prevent new access keys from being created. I think Option A might be a better solution since it covers both CreateUser and CreateAccessKey.

This question seems pretty straightforward. I think Option B is the best answer here - we need to deny IAM users from being created unless they're on an exception list, and that's exactly what this option does.
