   A service provider is designing a new API for their Junos devices to stream high-frequency BGP peer state changes to a central collector. The API must support strong typing, efficient binary serialization, and multiplexing of multiple streams over a single connection. The team is currently using a REST API and is evaluating gRPC. What is the primary advantage of gRPC over REST for this specific use case?

   • AgRPC uses JSON for payloads, which is more human-readable and easier to debug.
   • BgRPC is easier to debug because it uses standard HTTP methods like GET and POST.
   • CgRPC uses HTTP/2, which provides multiplexing and efficient binary serialization with Protocol Buffers.
   • DgRPC is inherently more secure than REST because it uses TLS by default.

   A network operator wants to collect streaming telemetry from a Junos device. They have configured the device to export data via gRPC and need to subscribe to specific sensor paths. The operator is using a Python script with the Junos telemetry interface. What is the first step the script must perform to establish the gRPC telemetry session?

   • ADefine the sensor paths in a YAML file and load it into the device.
   • BAuthenticate using a username and password over a separate SSH session.
   • CGenerate the .proto files from the Junos schema and compile them.
   • DEstablish a gRPC channel and create a stub for the telemetry service.
