False

True

8 / 20

How can you test the effectiveness of DDM in your Snowflake environment?

By querying the masked data and verifying the masked values.

By reviewing the audit logs to track access to masked data.

By using a vulnerability scanner to identify potential security risks.

All options are correct

9 / 20

DDM can be used to mask data based on data usage patterns.

True

False

10 / 20

You have a table named customer_data with columns first_name, last_name, and ssn. You want to mask the ssncolumn using a masking function that replaces the digits with 'X'. Which of the following SQL statements would you use to create a masked view?

CREATE MASKED VIEW masked_customer_data AS SELECT first_name, last_name, ENCRYPT(ssn) AS masked_ssn FROM customer_data;

CREATE MASKED VIEW masked_customer_data AS SELECT first_name, last_name, MASK(ssn) AS masked_ssn FROM customer_data;

CREATE MASKED VIEW masked_customer_data AS SELECT first_name, last_name, HASH(ssn) AS masked_ssn FROM customer_data;

CREATE MASKED VIEW masked_customer_data AS SELECT first_name, last_name, TOKENIZE(ssn) AS masked_ssn FROM customer_data;

11 / 20

DDM can be used to mask data based on specific conditions.

True

False

12 / 20

What are some best practices for implementing DDM in Snowflake?

Regularly review and update masking policies.

All options are correct

Identify sensitive data and classify it appropriately.

Create granular masking policies to control access to sensitive data.

13 / 20

DDM can be used to mask data in stored procedures and functions.

False

True

14 / 20

DDM can be used to mask data in real-time.

False

True

15 / 20

DDM can be used to mask data based on client applications.

True

False

16 / 20

How does DDM work in Snowflake?

By using a combination of encryption and tokenization.

By creating a separate masked view of the data.

By applying masking policies to specific columns and rows.

By encrypting the sensitive columns in the underlying tables.

17 / 20

DDM can be applied to both tables and views.

True

False

18 / 20

DDM can be used to mask data based on data quality metrics.

False

True

19 / 20

How can you apply a masking policy to a table or view?

By granting specific privileges to users.

By modifying the table or view definition.

By configuring the Snowflake security policies.

By creating a masked view.

20 / 20

What is the role of a masking policy in DDM?

To define the specific masking functions to apply.

All options are correct

To specify the columns and rows to be masked.

To determine which users can access the masked data.
