Show Suggested 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 thought only the role that created it could see unmasked data.

Wait, can it really be applied to external tables? Sounds odd.

I agree, and a single policy can apply to different tables too!

A masking policy can definitely be dropped from a table.

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?

I'm not entirely sure about option C; I feel like we might have gone over external tables, but I can't recall if masking policies apply to them.

I think option B sounds familiar, like we discussed how a single policy can cover multiple tables in our practice sessions.

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.

Okay, let's see. I know Dynamic Data Masking is used to protect sensitive data, but I'm not sure about the specifics of how it works.

C is a bit of a head-scratcher. Applying a masking policy to an external table's value column? Hmm, I'm not so sure about that one.

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.

I agree with Weldon. Applying a single masking policy to columns in different tables and the role creating the policy always seeing unmasked data make sense.

I'm pretty sure A and B are the correct answers. Dynamic Data Masking is all about applying a policy to mask sensitive data, and that policy should be able to be dropped or applied across different tables.
