CompTIA CS0-003 Exam - Topic 3 Question 38 Discussion

Actual exam question for CompTIA's CS0-003 exam

Question #: 38
Topic #: 3

An organization is planning to adopt a zero-trust architecture. Which of the following is most aligned with this approach?

ANetwork segmentation to separate sensitive systems from the rest of the network.

BWhitelisting specific IP addresses that are allowed to access the network.

CTrusting users who successfully authenticate once with multifactor authentication.

DAutomatically trusting internal network communications over external traffic.

Show Suggested Answer

Suggested Answer: A

Comprehensive and Detailed Step-by-Step

Network segmentation supports zero-trust principles by ensuring sensitive systems are isolated and access is restricted based on identity, role, and context. Unlike traditional models, zero-trust architecture does not automatically trust authenticated users or internal network traffic. It enforces strict access controls to minimize risk.

Wait, are we really trusting users after just one MFA? That sounds sketchy!

D is a big no, trusting internal traffic is against zero-trust principles.

C seems risky, just because they authenticate once doesn’t mean they’re safe.

I think B makes more sense, whitelisting is key!

A is definitely the way to go for zero-trust.

I feel like D is definitely not aligned with zero-trust. Trusting internal communications just seems counterintuitive to the whole concept.

I practiced a question similar to this, and I think trusting users after they authenticate once doesn't align with zero-trust principles. So, I’d lean away from C.

I'm not entirely sure, but I think whitelisting IPs could be part of a zero-trust strategy too. Maybe B is worth considering?

I remember studying network segmentation as a key principle of zero-trust. It seems like A might be the right choice.

Okay, I think I've got this. Zero-trust is about verifying access, not just network segmentation. So I'm going to go with option B, whitelisting specific IPs.

I'm pretty sure zero-trust is about not relying on network boundaries, so option D about trusting internal traffic doesn't seem right. I'm leaning towards A or B.

Hmm, I'm a bit confused. Zero-trust means verifying everything, right? So maybe option C about trusting users after MFA is the best answer.

This question seems straightforward. I think the zero-trust approach is about not automatically trusting anything, so option A seems most aligned with that.

I still think A) Network segmentation is the best choice for zero-trust architecture.

I see your point, Adell. Whitelisting can help, but network segmentation is more comprehensive in enforcing zero-trust.

Trusting internal traffic? That's like letting the fox guard the henhouse. Zero-trust all the way, baby!

But what about option B) Whitelisting specific IP addresses? Wouldn't that also align with zero-trust?

I agree with Ozell, because zero-trust architecture requires segmenting sensitive systems.

Ah, the classic network segmentation approach. It's like building a firewall around your sensitive data - except the firewall is made of Swiss cheese.
