Drag and drop the characteristics from the left onto the correct telemetry mode on the right. Select and Place: Answer: Explanation:  In a dial-in mode, the destination initiates a session to the router and subscribes to data to be streamed. Dial-in mode is supported over gRPC in only 64-bit platforms In a dial-out mode, the router initiates a… Read More »
