   A manufacturing company operates a robotic assembly line where each robot sends sensor data to a central cloud for analysis. The line must react to a faulty part within 50 milliseconds to avoid a collision. The current round-trip time to the cloud is 120 milliseconds. Which approach best meets the requirement?

   • AIncrease the bandwidth of the WAN link to the cloud to reduce the round-trip time.
   • BMove the cloud region closer to the factory to reduce the round-trip time.
   • CDeploy an edge gateway on the factory floor that runs the analysis locally and sends only alerts to the cloud.
   • DUse a faster cloud instance type to process the sensor data more quickly.

   Which benefit is directly associated with edge computing?

   • AIt reduces latency by processing data closer to the source.
   • BIt simplifies compliance by storing all data in a single jurisdiction.
   • CIt eliminates the need for any network connectivity.
   • DIt guarantees unlimited storage capacity at every edge node.

   A remote mining site has a limited WAN link to the corporate cloud. The site uses vibration sensors on conveyor belts to predict equipment failure. The prediction model requires continuous data, but the WAN link is often congested. Which approach best ensures the model receives the data it needs?

   • APrioritize sensor traffic on the WAN using QoS.
   • BSend only a sample of sensor data to the cloud for prediction.
   • CRun the prediction model on an edge server at the mining site using local sensor data.
   • DIncrease the WAN bandwidth to the site.

   A retail company uses edge computing to analyze customer traffic in stores. The analysis must be real-time to adjust staffing, but the company also wants to use the data for marketing insights. The stores have limited IT staff. Which approach best meets both needs with minimal operational overhead?

   • AUse a local server in each store to run both real-time analysis and marketing insights.
   • BDeploy edge appliances that run the real-time analysis and send summarized data to a cloud service for marketing insights.
   • CUse a central cloud for real-time analysis and store video locally for marketing insights.
   • DSend all video to the cloud for analysis and have the cloud send back staffing recommendations.

   A company is deciding between a centralized cloud and an edge computing architecture for a new application. The application requires real-time processing of sensor data and also needs to maintain a centralized dashboard for management. Which statement correctly describes the relationship between edge and cloud in this scenario?

   • AThe cloud must process all data to ensure the dashboard is accurate.
   • BEdge computing replaces the cloud entirely, so no centralized dashboard is possible.
   • CEdge computing processes data locally for real-time needs, while the cloud can still receive aggregated data for the dashboard.
   • DEdge computing is only useful for IoT devices and cannot support a management dashboard.
