Google Cloud Professional Data Engineer PDE — Topic 1 Question 176

Question

You have uploaded 5 years of log data to Cloud Storage. A user reported that some data points in the log data are outside of their expected ranges, which indicates errors. You need to address this issue and be able to run the process again in the future while keeping the original data for compliance reasons. What should you do?

Accepted Answer

Correct answer: C. The correct answer is C. Option C: Create a Dataflow workflow that reads the data from Cloud Storage, checks for values outside the expected range, sets the value to an appropriate default, and writes the updated records to a new dataset in Cloud Storage. Cloud Storage provides durable, scalable object storage that is fully managed. Dataflow runs serverless Apache Beam pipelines for stream and batch data processing with autoscaling.
