An engineer must deploy a Cisco FTD device. Management wants to examine traffic without requiring network changes that will disrupt end users. Corporate security policy requires the separation of management traffic from data traffic and the use of SSH over Telnet for remote administration. How must the device be deployed to meet these requirements?
B) in transparent mode with a management Interface
A) in routed mode with a diagnostic interface
C) in transparent made with a data interface
D) in routed mode with a bridge virtual interface

[All 300-710 Questions]

An engineer must deploy a Cisco FTD device. Management wants to examine traffic without requiring network changes that will disrupt end users. Corporate security policy requires the separation of management traffic from data traffic and the use of SSH over Telnet for remote administration. How must the device be deployed to meet these requirements?

Show Suggested Answer Hide Answer
Suggested Answer: B

To deploy a Cisco FTD device that meets the requirements of the question, the engineer must use transparent mode with a management interface. Transparent mode is a firewall configuration in which the FTD device acts as a ''bump in the wire'' or a ''stealth firewall'' and is not seen as a router hop to connected devices.In transparent mode, the FTD device can examine traffic without requiring network changes that will disrupt end users, such as changing IP addresses or routing configurations1. A management interface is a dedicated interface that is used for managing the FTD device and separating management traffic from data traffic.A management interface can be configured to allow SSH access for remote administration, which is more secure than Telnet2.

The other options are incorrect because:

Routed mode is a firewall configuration in which the FTD device acts as a router and performs address translation and routing for connected networks.Routed mode requires network changes that may disrupt end users, such as changing IP addresses or routing configurations1. A diagnostic interface is a special interface that is used for troubleshooting and capturing traffic on the FTD device. A diagnostic interface does not separate management traffic from data traffic or allow SSH access for remote administration.

Transparent mode with a data interface does not meet the requirement of separating management traffic from data traffic. A data interface is a regular interface that is used for passing and inspecting traffic on the FTD device.A data interface does not allow SSH access for remote administration2.

Routed mode with a bridge virtual interface (BVI) does not meet the requirement of examining traffic without requiring network changes that will disrupt end users. A BVI is a logical interface that acts as a container for one or more physical or logical interfaces that belong to the same layer 2 broadcast domain. A BVI allows the FTD device to route between different bridge groups on the same security module/engine. However, routed mode still requires network changes that may disrupt end users, such as changing IP addresses or routing configurations.

I’m leaning towards option A, but I’m not confident. Routed mode seems like it could complicate things with the traffic separation requirement.

I feel like I’ve seen a similar question before, and I think it was about using SSH for management. But I can't recall if that affects the mode choice here.

I think it might be option B, deploying in transparent mode with a management interface. That way, we can keep management and data traffic separate without disrupting users.

Okay, let's break this down step-by-step. We need to separate management and data traffic, use SSH for remote admin, and avoid disrupting end users. That's a lot to consider.

Ha, can you imagine if they asked us to use Telnet? That would be a total security nightmare. Good thing they're at least requiring SSH for remote access.

Yeah, I agree. And since the question mentions using SSH, that means we can't use Telnet, so option B with a management interface seems like the way to go.

Hmm, this question is tricky. We need to find a deployment option that separates management and data traffic while also using SSH for remote administration. I'm not sure if routed or transparent mode is the better choice here.
