Which method is used to gather data from a sensor?

Question

Options

• AConfigure the edge application to push data to the cloud.
• BSet up a rendezvous point where the sensor and edge application meet.
• CSet up a dedicate process for each sensor that grabs data.
• DPull data from the sensor.

• D

Explanation

Configuring the edge application to push data to the cloud (A) is correct because in IoT/edge computing architecture, the edge application acts as the local data collector from sensors and actively forwards (pushes) that data upstream to the cloud - this is the standard, scalable pattern since sensors lack public addresses that would allow the cloud to reach them directly.

Why the distractors are wrong:

• B (rendezvous point): This is a network routing concept (used in multicast), not an IoT data collection method.
• C (dedicated process per sensor): While technically possible, this is not the accepted method - it wastes resources and doesn't scale as the number of sensors grows.
• D (Pull from sensor): The cloud cannot reliably pull directly from sensors due to NAT, firewalls, and limited sensor networking capability; the edge application bridges that gap by pushing the data outward.

Memory tip: Think "edge pushes, cloud receives" - the edge application is always the active party that gathers local sensor data and pushes it toward the cloud, never the other way around.
