Telemetry data subscription defines the interactive relationship between the data sender and the data acquirer. Which of the following does not belong to the process of Telemetry static subscription?

Question

Options

• AThe analyzer analyzes the sampled data and sends the analysis results to the controller.
• BAfter completing the relevant configuration of the GRPC service for a device that supports
• CThe network device reports the collected data to the collector for reception and storage according
• DThe analyzer reads the sampling data stored by the collector

• A
  11% (5)
• B
  78% (35)
• C
  4% (2)
• D
  7% (3)

Explanation

Option B describes a step from dynamic subscription, not static subscription. In dynamic subscription, the collector or controller initiates a gRPC dial-in connection to the device, which requires configuring the gRPC service on the device beforehand. Static subscription is pre-configured directly on the network device, and the device autonomously pushes data to the collector - no gRPC dial-in setup is involved.

Options A, C, and D all describe valid steps in the static subscription workflow: the device samples and reports data to the collector (C), the analyzer reads that stored data (D), and then sends analysis results to the controller (A) - forming a complete data pipeline from device to decision-maker.

Memory tip: Think of static as "Set-and-Send" - the admin configures the device once, and it pushes data on its own. Dynamic (gRPC dial-in) is "Request-and-Receive" - an external system connects and requests data. Anything involving gRPC service setup points to dynamic, not static.
