The engineer wants to collect the Telemetry sampling data of the device through gRPC communication, and defines the serve function in the Python script, as detailed below. Which of the following…

Question

Exhibit

Options

• AThis function defines the opening of the gRPC listening service
• BServer is a gRPC server object, allowing a maximum of 10 threads
• CThis code contains exception catching and infinite loop monitoring functions
• DThe IP address of the device is 192.168.56.1, and the gRPC communication port number is 20000.

• A
  5% (2)
• B
  9% (4)
• C
  2% (1)
• D
  84% (37)

Explanation

Option D is wrong on two counts: the binding address [::] (or 0.0.0.0) in the add_insecure_port call means "listen on all network interfaces," not on the specific IP 192.168.56.1 - the script does not hardcode a device IP. Additionally, the port number in a standard gRPC telemetry script is typically 50051 (or another vendor-defined port), not 20000, so both the IP claim and the port claim are inaccurate.

Options A, B, and C are all correct descriptions: the serve() function does open a gRPC listening service (A); grpc.server(futures.ThreadPoolExecutor(max_workers=10)) creates a server object capped at 10 worker threads (B); and the typical pattern uses a try/except KeyboardInterrupt block wrapped around a while True: time.sleep(...) loop, providing both exception handling and continuous monitoring (C).

Memory tip: Think of [::] as "everywhere" - it's the IPv6 wildcard meaning "all interfaces," so no single IP address is ever hardcoded in the bind string. If an answer claims a specific device IP is embedded in the gRPC server setup, that's your red flag.
