What are characteristics of Dynamic Data Masking? (Select TWO).

Show Suggested Answer Hide Answer
Suggested Answer: C

For the configuration of data unloading in Snowflake, the valid option among the provided choices is 'C.' This is because Snowflake supports unloading data into Google Cloud Storage using the COPY INTO <location> command with specific configurations. The configurations listed in option C, such as Parquet file format with UTF-8 encoding and gzip compression, are all supported by Snowflake. Notably, Parquet is a columnar storage file format, which is optimal for high-performance data processing tasks in Snowflake. The UTF-8 file encoding and gzip compression are both standard and widely used settings that are compatible with Snowflake's capabilities for data unloading to cloud storage platforms. Reference:

Geography data type? That's interesting, didn't know that!

I have a vague memory of GEOGRAPHY data types, but I'm not confident if option E is correct. We might have touched on that in our review.

I remember something about roles and masking policies, so option D seems right. The creator should see unmasked data, right?

Alright, time to put my knowledge to the test. I'm pretty confident that a masking policy can't be applied to the value column of an external table, and the role that creates the policy won't always see unmasked data.

Ah, I remember learning about this in class. I believe a masking policy can be dropped, and it can be applied to columns in different tables. But I'm not certain about the other options.

I think I've got a handle on this. Dynamic Data Masking allows you to apply a masking policy to columns, but I'm not sure if that policy can be applied across different tables.

E is probably not correct. I don't think Dynamic Data Masking can be applied to a GEOGRAPHY data type column. That just seems a bit too specific.

D sounds like it could be a valid answer too. If the role that creates the masking policy can see the unmasked data, that's an important characteristic of Dynamic Data Masking.
