Show Suggested Answer Hide Answer
Suggested Answer: B

https://cloud.google.com/bigquery/docs/scan-with-dlp

Cloud Data Loss Prevention API allows to detect and redact or remove sensitive data before the comments or reviews are published. Cloud DLP will read information from BigQuery, Cloud Storage or Datastore and scan it for sensitive data.

Wait, can you really prevent credit card data from being ingested?

I don't think enabling Cloud Identity-Aware Proxy would help with this specific issue. It seems more focused on access control rather than data redaction.

I feel like Security Command Center is more about monitoring than actually preventing sensitive data from being stored. Is that right?

I'm not entirely sure, but I think creating a BigQuery view with regex might not be enough to prevent credit card numbers from being stored in the first place.

I remember we discussed using the Cloud Data Loss Prevention API in class. It seems like a solid choice for redacting sensitive information.

Option D with Cloud Identity-Aware Proxy sounds promising to filter out the sensitive data before it reaches BigQuery. I'll make sure to understand how that service works.

Option C with Security Command Center could be a good way to scan for and identify any credit card numbers, but I'm not sure if that fully solves the problem of preventing them from being stored in the first place.

The regular expression approach in option A seems a bit risky to me. I'd rather use a more robust data protection service like the one in option B.

Hmm, I'm not too familiar with the Cloud Data Loss Prevention API. I'll need to read up on that option to understand how it can help redact sensitive data.

This looks like a straightforward data security question. I'll focus on the key requirements - no credit card numbers in BigQuery and using the right Google Cloud services.

Option C with Security Command Center is an interesting idea, but I doubt it's the most efficient solution here. B is clearly the winner.

Haha, option D made me chuckle. Filtering out credit card numbers with Cloud Identity-Aware Proxy? Sounds like a roundabout way to do it.
