Questions 1–10 of 10

1. Where does Dynamic Data Masking (DDM) apply its masking?
Question 1A. Permanently at rest in the datastoreB. In transit, on the fly, so the data in the datastore is unchangedC. In a separate copy of the production databaseD. Only in backupsE. Only in development environments
2. What proportion of data is described as structured data, compared with the semi-structured and unstructured data of the new era?
Question 2A. 50%B. 80%C. 5%D. 20%E. 100%
3. Why has Dynamic Data Masking become popular?
Question 3A. Because with 80% more semi-structured and unstructured data it became troublesome to anonymise data within a given SLA using static maskingB. Because regulators banned Static Data MaskingC. Because it requires no computing resourcesD. Because it permanently deletes sensitive dataE. Because structured data no longer needs masking
4. Which masking approach requires a copy of production data to be made before masking?
Question 4A. Dynamic Data MaskingB. Both SDM and DDMC. Static Data MaskingD. Neither SDM nor DDME. Only DDM when run in real time
5. How do SDM and DDM differ in when the masking is processed?
Question 5A. Both are real-timeB. Both are batchC. SDM is real-time and DDM is batchD. SDM is done weekly and DDM monthlyE. SDM is done in batches which take time, whereas DDM is real-time
6. Why does Dynamic Data Masking carry an additional performance requirement?
Question 6A. Because it copies the whole database every nightB. Because it runs along with every SQL statement sent to the datastoreC. Because it must re-index every tableD. Because it stores masked data in a second datastoreE. Because it encrypts the data at rest
7. How is Static Data Masking run, compared with Dynamic Data Masking?
Question 7A. SDM is a permanent layer and DDM a standalone processB. Both are permanent layersC. Both are standalone processesD. SDM is a standalone process, whereas DDM is a permanent layer before exposing data to usersE. SDM runs inside the application and DDM inside the database
8. Which of the following is NOT true of Dynamic Data Masking?
Question 8A. It permanently changes the data at restB. It masks data in transitC. It uses the same production data rather than a copyD. It is real-timeE. It behaves like standard Data Masking in what it does to the values
9. Which group's maturing practices have increased the demand for production-ready masked data?
Question 9A. Network engineersB. AuditorsC. Data Scientists developing, training and publishing modelsD. Marketing teamsE. Help desk staff
10. Why is Static Data Masking described as a very slow process?
Question 10A. Because it runs with every SQL queryB. Because it must be approved by regulators each timeC. Because it works only on unstructured dataD. Because it masks data in transitE. Because one must create a new dataset containing the masked data
