CompTIA CV0-004 Exam - Topic 1 Question 4 Discussion

Actual exam question for CompTIA's CV0-004 exam

Question #: 4
Topic #: 1

A cloud administrator recently created three servers in the cloud. The goal was to create ACLs so the servers could not communicate with each other. The servers were configured

with the following IP addresses:

After implementing the ACLs, the administrator confirmed that some servers are still able to reach the other servers. Which of the following should the administrator change to

prevent the servers from being on the same network?

AThe IP address of Server 1 to 172.16.12.36

BThe IP address of Server 1 to 172.16.12.2

CThe IP address of Server 2 to 172.16.12.18

DThe IP address of Server 2 to 172.16.14.14

Show Suggested Answer

Suggested Answer: B

To prevent the servers from being on the same network and communicating with each other, the administrator should change the IP address of Server 1 to 172.16.12.2. This IP address is outside the subnet defined by the subnet mask 255.255.255.240, which would place Server 1 on a different subnet, preventing direct communication without routing.

I agree, the ACLs should have worked if configured correctly.

Wait, are they really still on the same network? That seems odd.

I think Server 2's IP should be changed to 172.16.14.14.

The servers need different subnets to isolate them.

I’m a bit confused about the IP ranges, but I think if we change Server 1's IP to 172.16.12.36, it might help separate them.

This question reminds me of a practice exam where we had to configure ACLs. I think the key is ensuring the servers are on different networks.

I'm not entirely sure, but I feel like changing the IP of Server 2 to 172.16.14.14 might be the right move since it seems like a different subnet.

I remember studying about subnetting, and I think the servers need to be in different subnets to prevent communication.

Ah, I see what's going on now. The administrator needs to move the servers to different networks to prevent them from communicating. Option D looks like the best choice to achieve that.

This seems straightforward. The servers are on the same network, so the administrator needs to change the IP address of one of the servers to a different subnet to isolate them. I'll go with option D.

I'm a bit confused here. The question mentions ACLs, but the answer choices are all about IP addresses. I'll need to re-read this carefully to make sure I understand the core issue.

Okay, I think I've got this. The key is to identify that the servers are on the same network since they have overlapping IP addresses. I'll choose the option that changes the IP address to a different subnet.

Hmm, this looks like a tricky one. I'll need to carefully analyze the IP addresses and network configuration to determine the best solution.

Alright, I've got it. The answer is option B - "Right". When adding network elements in u2000, you can only add the right ones, not the wrong ones. Simple enough!

This looks pretty straightforward. I'll just need to update the nameserver in the resolv.conf file and then use the host command to resolve the server name.

The 6M approach is the most common way to set up a Fishbone Diagram, so I'll go with that as my answer.

That's a good point, Sage. Maybe changing the IP address of Server 2 to 172.16.14.14 would also help.

But what if changing the IP address of Server 1 is not enough? Shouldn't we also consider changing the IP address of Server 2?

I agree with you, Isabelle. Changing the IP address of Server 1 should prevent communication between servers.

Hmm, I'm not so sure about that. Changing the IP addresses alone might not be enough. We'd also need to make sure the routing tables and firewall rules are properly configured to isolate the servers. This is starting to sound like a real headache!

Yeah, that's a good point. The servers need to be on completely separate networks to ensure they can't communicate. I'd say the answer is either option D, changing Server 2's IP to a different subnet, or maybe even creating a completely new VPC for each server.

I agree, the IP addresses could be the problem here. If the servers are still on the same network, that would explain why they can still reach each other despite the ACLs.

Hmm, this question is a bit tricky. The goal is to prevent the servers from communicating with each other, but the administrator is having trouble despite implementing ACLs. I'm wondering if the issue might be with the IP addresses themselves.
