   A university is expanding its campus network to a new building, but the new building must connect to the existing core network that uses proprietary routing protocols. The design team must ensure the new building's equipment can participate in the existing routing domain. What is the primary design constraint in this brownfield scenario?

   • AThe new equipment must be compatible with the existing routing protocols and configuration standards.
   • BThe new building should have a completely independent routing design to avoid any interference.
   • CThe existing core network must be replaced to support the new building.
   • DThe new building should use a different routing protocol to modernize the network.

   A hospital is upgrading its network to support new wireless medical devices. The existing wired network uses older switches that do not support the required VLAN tagging for the new devices. The upgrade must not disrupt patient care during business hours. What is the most appropriate design consideration for this brownfield deployment?

   • AReplace all switches overnight in a single weekend, accepting that some downtime may occur.
   • BPlan a phased migration that introduces new switches and VLANs during scheduled maintenance windows.
   • CConfigure the new VLANs on the existing switches even though they do not support the required tagging.
   • DDeploy the new devices on the same flat network without VLANs to avoid any changes.

   A manufacturing company is building a new factory network from scratch. The operations manager wants to implement a segmented network with IoT devices on a separate VLAN and strict access controls. What is the main advantage of this greenfield deployment for meeting these requirements?

   • AThe existing network's VLAN configuration can be reused to save time.
   • BThe design can be created specifically to support the required segmentation and security without retrofitting legacy systems.
   • CThe network will automatically be secure because it is new.
   • DThe network can be deployed quickly by using the same design as the company's older factories.
