   A government agency is upgrading its network to support new secure communication requirements. The existing network uses a mix of legacy routers and switches that are still under support. The agency cannot afford a complete replacement. What is the most appropriate brownfield strategy?

   • AIncrementally replace or upgrade components that are incompatible, while keeping the rest of the network operational.
   • BDecommission the existing network and build a new one from scratch.
   • CKeep the existing network unchanged and add a separate secure network.
   • DReplace all equipment at once to ensure uniformity.

   A retail chain is opening a new flagship store in a building that has never had network cabling. The IT director wants the network to support future IoT sensors and high-definition video surveillance, and there is no existing equipment to reuse. Which approach best aligns with the greenfield nature of this project?

   • AReuse the existing cabling and switches from the previous tenant to reduce costs, even though they are outdated.
   • BInstall the same equipment model used in other stores to ensure consistency, regardless of the new store's specific needs.
   • CDesign the network from scratch, selecting modern technologies that meet the stated future requirements without legacy constraints.
   • DDeploy a temporary wireless network and defer structured cabling decisions until after the store opens.

   A bank is upgrading its core network to support new compliance requirements. The existing network has been in place for 10 years and uses a mix of vendor equipment. The upgrade must not cause downtime during trading hours. Which strategy is most appropriate for this brownfield deployment?

   • ADeploy the new equipment in parallel with the old and cut over without testing.
   • BIgnore the existing vendor mix and assume all new equipment will interoperate.
   • CImplement the upgrade in phases, testing each phase during off-hours to ensure compatibility and minimize disruption.
   • DReplace all equipment in one weekend to complete the upgrade quickly.

   How does greenfield status affect the gathering of customer network design requirements?

   • ARequirements are limited to what can be achieved with the existing hardware and software.
   • BRequirements are gathered primarily from existing network documentation and performance data.
   • CRequirements are gathered from business goals and future needs, with no existing infrastructure to limit the scope.

   A school district is upgrading its network to support 1:1 student devices. The existing network uses older switches that only support 100 Mbps and do not have PoE for the new wireless access points. The upgrade must be completed over the summer break. What is the most important consideration for this brownfield deployment?

   • AEnsure the new switches are compatible with the existing cabling and provide the required PoE and bandwidth.
   • BDelay the upgrade until the next school year to have more time.
   • CReplace all cabling in the district to support the new speeds.
   • DDeploy the new devices on the existing switches and accept the lower speeds.
