   A logistics company uses autonomous forklifts in a warehouse. The forklifts need to coordinate with each other to avoid collisions. The coordination must work even if the internet connection to the corporate data center is lost. Which solution should the company implement?

   • ARun a local edge server in the warehouse that handles forklift coordination and communicates with the data center when available.
   • BUse a cloud-based coordination service that is highly available.
   • CPre-program the forklifts with fixed routes to avoid collisions.
   • DInstall a backup internet link to the data center.

   A smart building uses edge computing to control HVAC systems. The building manager also wants to use the data to optimize energy usage across multiple buildings. The edge controllers have limited compute resources. Which approach best meets both real-time control and cross-building optimization?

   • AUse edge controllers for real-time HVAC control and send aggregated energy data to a central system for optimization.
   • BUse a central system for real-time control and store data locally for optimization.
   • CSend all HVAC data to the central system and have it control the HVAC in real time.
   • DUse only local controllers with no central data collection.

   A utility company wants to deploy smart meters that send usage data to a central system. The company also wants to use the data for real-time demand response. The meters have limited processing power. Which architecture best meets both real-time demand response and central billing needs?

   • ASend all meter data to the central system and have it control demand response.
   • BUse edge gateways in neighborhoods to process real-time demand response and send aggregated usage data to the central system for billing.
   • CUse the meters themselves to make demand response decisions and send all data to the central system.
   • DUse a central system for demand response and store data locally for billing.

   A company is considering edge computing for a new application. The application requires low latency, but the company also has a strict data governance policy that requires all data to be stored in a specific country. The company's cloud provider does not have a data center in that country. Which statement correctly addresses this constraint?

   • AThe company should use a different cloud provider that has a data center in the required country, but this does not solve the latency problem.
   • BThe company must use the cloud provider's data center in a neighboring country and accept the latency.
   • CEdge computing cannot be used because data must be stored in a specific country and edge devices are not compliant.
   • DEdge computing can be used to process data locally and store it on edge devices within the required country, while the cloud is used only for non-sensitive aggregated data.

   Which statement best describes edge computing compared to centralized cloud computing?

   • AEdge computing replaces all cloud services with local servers that never connect to the internet.
   • BEdge computing moves computation and data storage closer to the devices that generate or consume the data.
   • CEdge computing relies exclusively on satellite links to connect remote devices to a cloud provider.
   • DEdge computing processes data at a central data center to ensure consistent policy enforcement.
