A data pipeline uses Cloud Pub/Sub for ingesting data. The data is stored in topics and a Dataflow workflow reads from a subscription to that topic, processes the data, and writes output to BigQuery. What is the recommended way to authenticate when reading data from Cloud Pub/Sub?

You are using BigQuery with a regional dataset that includes a table with the daily sales volumes. This table is updated multiple times per day. You need to protect your sales table in case of regional failures with a recovery point objective (RPO) of less than 24 hours, while keeping costs to a minimum. What should you do?
