Google Cloud Professional Cloud Security Engineer — Question 43

As adoption of the Cloud Data Loss Prevention (Cloud DLP) API grows within your company, you need to optimize usage to reduce cost. Cloud DLP target data is stored in Cloud Storage and BigQuery. The location and region are identified as a suffix in the resource name.
Which cost reduction options should you recommend?

Answer options

• A. Set appropriate rowsLimit value on BigQuery data hosted outside the US and set appropriate bytesLimitPerFile value on multiregional Cloud Storage buckets.
• B. Set appropriate rowsLimit value on BigQuery data hosted outside the US, and minimize transformation units on multiregional Cloud Storage buckets.
• C. Use rowsLimit and bytesLimitPerFile to sample data and use CloudStorageRegexFileSet to limit scans.
• D. Use FindingLimits and TimespanContfig to sample data and minimize transformation units.

Correct answer: C

Explanation

The correct answer, C, suggests using rowsLimit and bytesLimitPerFile to sample data, which effectively reduces the amount of data processed and thus lowers costs. Additionally, CloudStorageRegexFileSet helps to limit the scans to only the relevant files, further optimizing usage. The other options either do not adequately address sampling or focus on settings that do not effectively reduce costs.
