TerramEarth manufactures heavy equipment for the mining and agricultural industries and currently has over 500 dealers and service centers in 100 countries. There are 20 million TerramEarth vehicles in operation that collect 120 fields of data per second, with about 200,000 of these vehicles connected to a cellular network. The current FTP data transfer process is error-prone, restarting from the beginning when connections fail. To speed up data retrieval and improve reliability, more vehicles will be upgraded to cellular connections to transmit data to the ETL process. How should you redesign the data transfer process to improve reliability and minimize data transfer time on the cellular connections? | Google Professional Cloud Architect Quiz
