Google Professional Cloud Security Engineer Exam - Topic 2 Question 83 Discussion

Your company conducts clinical trials and needs to analyze the results of a recent study that are stored in BigQuery. The interval when the medicine was taken contains start and stop dates The interval data is critical to the analysis, but specific dates may identify a particular batch and introduce bias You need to obfuscate the start and end dates for each row and preserve the interval data.What should you do?
A) Use bucketing to shift values to a predetermined date based on the initial value.
B) Extract the date using TimePartConfig from each date field and append a random month and year
C) Use date shifting with the context set to the unique ID of the test subject
D) Use the FFX mode of format preserving encryption (FPE) and maintain data consistency

[All Professional Cloud Security Engineer Questions]

Your company conducts clinical trials and needs to analyze the results of a recent study that are stored in BigQuery.

What should you do?

Show Suggested Answer Hide Answer
Suggested Answer: A

'Date shifting techniques randomly shift a set of dates but preserve the sequence and duration of a period of time. Shifting dates is usually done in context to an individual or an entity. That is, each individual's dates are shifted by an amount of time that is unique to that individual.'

I feel like option B could introduce too much randomness. We need to keep the intervals intact, so I’m leaning towards option C for that reason.

I practiced a similar question where we had to anonymize data. I think option A could work, but I'm worried about how it might affect the analysis.
