Answer: Make an RDB backup of the Redis database, use the gsutil utility to copy the RDB file into a Cloud Storage bucket, and then import the RDB file into the Memorystore for Redis instance.
The correct answer is A. The import and export feature uses the native RDB snapshot feature of Redis to import data into or export data out of a Memorystore for Redis instance. This method is the most efficient in terms of time, cost, and effort. It leverages Cloud Storage buckets for storing RDB files, which allows for easy data migration within Google Cloud or outside of it. This method follows Google's recommended practices for migrating Redis databases to Memorystore for Redis.
