CompTIA Exam CV0-004 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 think changing the IP address of Server 2 is the key here. That way, we can ensure the servers are on different networks.

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.

Actually, I think changing the IP address of Server 2 to 172.16.14.14 could also be a valid option. It would separate the servers even more.

I agree with Loren, changing the IP address of Server 2 might be the solution. It could prevent the servers from being on the same network.

But what if changing the IP address of Server 1 doesn't solve the issue? Maybe changing the IP address of Server 2 to 172.16.12.18 could work.

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.
