Google Professional Data Engineer Exam - Topic 4 Question 76 Discussion

You have a data stored in BigQuery. The data in the BigQuery dataset must be highly available. You need to define a storage, backup, and recovery strategy of this data that minimizes cost. How should you configure the BigQuery table?
C) Set the BigQuery dataset to be multi-regional. In the event of an emergency, use a point-in-time snapshot to recover the data.
A) Set the BigQuery dataset to be regional. In the event of an emergency, use a point-in-time snapshot to recover the data.
B) Set the BigQuery dataset to be regional. Create a scheduled query to make copies of the data to tables suffixed with the time of the backup. In the event of an emergency, use the backup copy of the table.
D) Set the BigQuery dataset to be multi-regional. Create a scheduled query to make copies of the data to tables suffixed with the time of the backup. In the event of an emergency, use the backup copy of the table.

Wait, can you really recover from a point-in-time snapshot? Sounds risky!

I feel like point-in-time snapshots could be a good choice, but I can't recall if they work better with regional or multi-regional settings.

I think option B sounds familiar because we practiced creating scheduled queries for backups, but I'm not entirely confident about the cost implications.

Regarding D, I think it could be misleading because not all automated systems fix vulnerabilities immediately after a patch release; there might be some conditions involved.

Hmm, the question is asking about a service that's timing out due to heavy database load. I'm thinking the service autonomy principle might be the best approach here, since the service should be able to handle the database load independently.

Okay, let me think this through. I believe the key is that the hash of the previous block is included in the header of the current block, creating a cryptographic link between them. That way, any tampering with a past block would be detected.
