   How does edge computing improve bandwidth efficiency?

   • ABy increasing the capacity of the core network links.
   • BBy sending only relevant or processed data to the central cloud instead of raw data.
   • CBy using satellite links that have higher throughput.
   • DBy compressing all data before transmission to the cloud.

   A retail chain operates 200 stores, each with 50 IP cameras generating continuous video streams. The current design sends all video to a central cloud for processing, consuming 10 Gbps of WAN bandwidth. The company wants to reduce WAN costs while still being able to search for specific events (e.g., a person entering a restricted area) across all stores. Which edge computing strategy best meets this requirement?

   • AStore all video locally at each store and never upload to the cloud.
   • BDeploy edge servers at each store that run video analytics locally and upload only clips of detected events.
   • CCompress all video streams at the camera and send the compressed stream to the cloud.
   • DIncrease the WAN bandwidth to handle the full video load.

   An oil platform has a satellite link to a central cloud with intermittent connectivity. The platform's monitoring system must continue to detect and alert on pressure anomalies even when the link is down. Which edge computing approach best satisfies this requirement?

   • ARely on the central cloud to detect anomalies and send alerts via satellite.
   • BRun the anomaly detection model on an edge device at the platform and queue alerts for transmission when connectivity returns.
   • CUse a second satellite provider to increase link reliability.
   • DStore all sensor data locally and upload it only when the link is up, but do no local analysis.

   An oil pipeline uses thousands of sensors that generate 10 GB of data per day per site. The data is currently streamed to a central data center for analysis, but the WAN link is saturated and the cost is high. The analysis only needs hourly summaries. Which approach reduces bandwidth usage while still providing the needed insights?

   • AUpgrade the WAN link to a higher capacity connection.
   • BCompress the sensor data at the sensor level and send the compressed stream to the central data center.
   • CDeploy edge devices at each site that aggregate and filter the sensor data before sending only summaries to the central data center.
   • DStore the data locally and send it to the data center once a week.

   A manufacturing company has multiple plants, each with its own edge server for real-time process control. The company wants to implement a centralized monitoring system that can view all plants. The plants have different network conditions. Which design best supports centralized monitoring without compromising local control?

   • AUse a separate edge server for monitoring and another for control.
   • BHave each edge server send real-time telemetry to a central monitoring system while keeping control logic local.
   • CHave each plant send only daily reports to the central system.
   • DMove all control logic to the central monitoring system.
