   A hospital uses wearable monitors that send patient data to a central cloud. The network team wants to reduce the amount of data transmitted while still being able to review complete patient histories. Which edge computing technique achieves this?

   • AIncrease the frequency of data uploads to ensure the cloud has the latest data.
   • BUse a lower-resolution sensor to reduce data size.
   • CProcess the data on an edge gateway to filter out normal readings and send only abnormal events to the cloud.
   • DHave the wearable device buffer data and upload it only when the patient is near a Wi-Fi access point.

   In network automation, which task is commonly performed at the edge?

   • APerforming all software updates for network devices from a single cloud server.
   • BRunning a local controller that monitors and adjusts network devices in real time.
   • CAggregating logs from all branches into a single SIEM platform.
   • DStoring the entire network configuration history in a central database.

   A company is designing a new IoT solution and must choose between a centralized cloud and an edge computing architecture. The application requires sub-20 ms response times, generates 10 TB of data per day, and must remain operational during internet outages. Which statement correctly justifies the edge computing choice?

   • AEdge computing is required for all IoT applications, so the choice is obvious.
   • BEdge computing meets the sub-20 ms latency requirement, reduces the data volume sent to the cloud, and continues operating during internet outages.
   • CEdge computing is always faster than the cloud because it uses local processing.
   • DEdge computing eliminates the need for any cloud resources, so the company can avoid cloud costs entirely.

   A smart city deploys traffic light controllers that must adjust signal timing based on real-time vehicle flow data. The city's network team is evaluating whether to process the data at a nearby edge node or in a centralized cloud. Which factor most strongly favors the edge node?

   • AThe city wants to use a single vendor's cloud platform for all applications.
   • BThe traffic control algorithm requires decisions within 50 milliseconds of sensor input.
   • CThe traffic data is not sensitive and can be transmitted over the public internet.
   • DThe city wants to store all traffic data for long-term trend analysis.

   A hospital uses wearable monitors that transmit patient vitals to a central server. The network team must ensure that alerts for critical conditions are delivered even if the central server is unreachable. Which approach provides the required reliability?

   • AIncrease the number of central servers to provide redundancy.
   • BDeploy edge gateways in each ward that process vitals locally and raise alarms if the central server is unreachable.
   • CStore all vitals on the wearable device until the central server is reachable.
   • DUse a backup WAN link to the central server.
