Question #: 76
Topic #: 4

[All Professional Data Engineer Questions]

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?

ASet the BigQuery dataset to be regional. In the event of an emergency, use a point-in-time snapshot to recover the data.

BSet 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.

CSet the BigQuery dataset to be multi-regional. In the event of an emergency, use a point-in-time snapshot to recover the data.

DSet 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.

I remember we discussed the importance of using multi-regional datasets for high availability, but I'm not sure if snapshots are the best option for recovery.

Okay, I think I've got a strategy. I'll want to set the dataset to be multi-regional for high availability, and then create scheduled backups to protect against data loss.

Hmm, I'm a little unsure on this one. I know a social security card is used to verify identity, but I'm not sure if that's enough to prove authorization to work. I'll have to think this through carefully.

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.

The question is asking about the correct description of the DR, so I'll need to carefully read through the options and apply my knowledge of OSPF to determine the right answer.
