Which of the following factors should be considered when evaluating a firewall to protect a datacenter's east-west traffic?
When evaluating a firewall to protect a datacenter's east-west traffic, the key factor to consider is the traffic between VMs running on different hosts. East-west traffic refers to the internal communication within a datacenter, specifically traffic between servers, virtual machines, and other infrastructure components inside the datacenter. This contrasts with north-south traffic, which involves data moving in and out of the datacenter. Therefore, the traffic between VMs on different hosts is a primary consideration when securing east-west traffic within a datacenter.
Shouldn't be the answer B? because in east-west trafic case we dosen't go out from server boundries? or am i missing something here?
I agreed. Traffic flows within a datacenter typically occur within the framework of one of two models: East-West or North-South. The names may not be the most intuitive, but the East-West traffic model means that data is flowing among devices within a specific datacenter while North-South means that data is flowing into the datacenter (from a system physically outside the datacenter) or out of it (to a system physically outside the datacenter).

I am not 100% on this conclusion, but here's why I think it's A: I think this question is tripping us up because we are looking for an instance of East-West traffic, while the question is really looking for a potential risk factor that could *compromise* EW traffic. So, the actual answer should be A, since replication traffic could carry replicated EW traffic, despite its own nature being North-South. A tech must keep this in mind to protect the EW data of the main center.
After re-reading your comment and referring to the question TONS of times I agree 100% with the way you're thinking.
You are evaluating a Firewall in this instance: its nothing to do with "replication" the answer is B, is A is purely N-S
B. Traffic between VMs running on different hosts
B, because there are different hosts and will be traffic from east to west, replication traffic as stated in answer A makes no sense
The answer is B. Traffic between VMs running on different hosts. Here's why: East-West Traffic: It refers to the internal communication within a data center, specifically between servers, virtual machines (VMs), and other infrastructure components.
Choice A, “Replication traffic between an on-premises server and a remote backup facility,” is typically considered north-south traffic, not east-west traffic. North-south traffic refers to client-to-server traffic that moves between the data center and a location outside the data center network. This includes traffic between the data center and remote locations, such as a backup facility. On the other hand, east-west traffic refers to traffic that remains within the data center, such as the traffic between different virtual machines (VMs) on different hosts. Therefore, when evaluating a firewall to protect a datacenter’s east-west traffic, it’s more relevant to consider the traffic between VMs running on different hosts (Choice B).
The best answer is B. This is because a firewall designed to protect east-west traffic should be able to inspect and filter the traffic between VMs running on different hosts. This is essential for isolating workloads, investigating how applications traverse across the network, and preventing lateral movement to stop attackers from moving east-west through the system. Which is why traffic between VM's running between different hosts should be a consideration when evaluating a firewall that protects internal (east-west) traffic.
You are trying to ensure data can be made redundant through replication within the same network & not transported out (North-Bound) by router, or firewall protocols. It's important to consider how to keep data secure in your network without letting remnants being having a risk of being tracked outside your firewall security.

Answer is B. A would be north-south traffic.
I think the answer is A, not to get to technical, but East-West Traffic is normally communications between servers, and backups are usually sent to a 'server' and this scenario discusses a servers interaction with another server regardless if one was backup or not.
B East-west traffic specifically refers to the communication that occurs within a data center, between servers, applications, and virtual machines (VMs). It's distinct from north-south traffic, which involves traffic entering or exiting the data center from external networks. Option B directly addresses this internal traffic flow, highlighting the importance of protecting communication between VMs residing on different hosts within the data center.
tell me exactly answer for this question? chatgpt it gives more details, it looks like the question incomplete.
In computer networking, east-west traffic is network traffic among devices within a specific data center. The other direction of traffic flow is north-south traffic, data flowing from or to a system physically residing outside the data center. Answer is B. The data is NOT leaving the data centre so cant be A, C or D
the key is EAST-WEST traffic.
Simplification , ignore the words East-West and replace them with internal network then read the question again, you will find that the question is about all the factors that can affect the internal network , answer being offsite replication which has the potential risk of bringing in malicious data Answer being : A
East-west traffic refers to communication between servers or virtual machines within the same datacenter.
