Actual exam question for Eccouncil's 312-38 exam

Topic #: 10
[All 312-38 Questions]

The Circuit-level gateway firewall technology functions at which of the following OSI layer?

Show Suggested Answer Hide Answer
Suggested Answer: B

Circuit-level gateway firewall technology operates at the session layer of the OSI model. This type of firewall validates TCP or UDP sessions before allowing traffic through, without inspecting the contents of the data packets. It acts as a handshaking device between trusted clients or servers and untrusted hosts, ensuring that the session packets adhere to established rules for a connection.The session layer, which is Layer 5 in the OSI model, is responsible for setting up, managing, and terminating the connections between applications1234.

Really? I didn't think firewalls worked at that layer.

Nope, it's Transport layer for sure!

I’m torn between the Session layer and the Transport layer for this one. I should have reviewed that section more thoroughly!

I’m pretty confident that circuit-level gateways function at the Transport layer, similar to how TCP connections are managed.

I remember practicing a question about firewalls, and I think they work at the Session layer, but that feels a bit off now.

Okay, I've got this. Circuit-level gateways work at the network layer, filtering and controlling traffic between networks. I'm confident that C is the right answer.

Hmm, I'm a bit unsure about this one. I know firewalls operate at different layers, so I'll need to carefully consider the details of circuit-level gateways.

This seems like a straightforward OSI layer question. I'll think through the firewall functionality and try to match it to the correct layer.

Wait, I'm confused. Isn't a circuit-level gateway more like a proxy server, operating at the session layer? I'll have to review my networking concepts before answering this.

I feel confident that the correct answer is Incident Prioritization. The IRT will need to assess the severity and impact of the incident to determine the appropriate response.

I'm a little confused on this one. I know we need to configure the XML resource file, but I'm not sure which specific settings we need to change. Maybe I should review the Lightning web component documentation again to make sure I understand the requirements.

Agreed. This question is pretty straightforward. The only real challenge is making sure you understand the difference between the network layer and the other OSI layers. But if you know your stuff, C) is the obvious choice.

I'm with you guys. The circuit-level gateway is all about the network layer, controlling the flow of packets and securing the network. It's not really concerned with the higher-level session or application stuff.

That's a good point, Elly. But I think the key distinction is that the circuit-level gateway is more focused on the network-level functions, like IP routing, rather than the end-to-end transport-layer functions. So I still think C) Network layer is the best answer.

Hmm, I'm not so sure about that. Aren't circuit-level gateways also responsible for managing TCP/UDP connections? Wouldn't that mean they're working at the transport layer as well?

I agree with Tawna. The circuit-level gateway firewall is responsible for making routing decisions and controlling the flow of traffic at the network layer. It's not operating at the data-link, session, or transport layers.

This question is a bit tricky, but I think the answer is C) Network layer. The circuit-level gateway firewall operates at the network layer, filtering traffic based on IP addresses and protocols.
