Question # 1

You need to store and analyze social media postings in Google BigQuery at a rate of 10,000 messages per minute in near real-time.

Options:

A.  

Re-write the application to load accumulated data every 2 minutes.

B.  

Convert the streaming insert code to batch load for individual messages.

C.  

Load the original message to Google Cloud SQL, and export the table every hour to BigQuery via streaming inserts.

You want to minimize the storage cost of the migration. What should you do?

Options:

A.  

Put the data into Google Cloud Storage.

B.  

Use preemptible virtual machines (VMs) for the Cloud Dataproc cluster.
