Snowflake SnowPro Advanced: Data Engineer (DEA-C02) Sample Questions:

1. You are tasked with implementing data masking on a 'CUSTOMER' table. The requirement is to mask the 'EMAIL' column for all users except those with the 'DATA ADMIN' role. You have the following code snippet. What is wrong with it?

A) The WITH clause is unneccessary.
B) The masking policy syntax is incorrect. It should use 'CASE WHEN IS_ROLE_IN_SESSION('DATA_ADMIN') THEN EMAIL ELSE '[email protected]' END'.
C) There is no code provided, so there is nothing wrong with it.
D) The masking policy is applied to the wrong column. It should be applied to the ID column, not the EMAIL column.
E) Without masking poliy code, it's impossible to determine if there is anything wrong.

2. You have a requirement to continuously load data from a cloud storage location into a Snowflake table. The source data is in Avro format and is being appended to the cloud storage location frequently. You want to automate this process using Snowpipe. You've already created the Snowpipe and the associated stage and file format. However, you notice that some files are being skipped during the ingestion process, and data is missing in your Snowflake table. What is the MOST likely reason for this issue, assuming all necessary permissions and configurations (stage, file format, pipe definition) are correctly set up?

A) The file format definition in Snowflake is incompatible with the Avro schema.
B) The data files in cloud storage are not being automatically detected by Snowpipe.
C) The Snowpipe is paused due to exceeding the daily quota.
D) Snowflake does not support Avro format for Snowpipe.
E) The cloud storage event notifications are not properly configured to trigger Snowpipe.

3. You are developing a Snowpark Python application that needs to process data from a Kafka topic. The data is structured as Avro records. You want to leverage Snowpipe for ingestion and Snowpark DataFrames for transformation. What is the MOST efficient and scalable approach to integrate these components?

A) Configure Snowpipe to ingest the raw Avro data into a VARIANT column in a staging table. Utilize a Snowpark DataFrame with Snowflake's get_object field function on the variant to get an object by name, and create columns based on each field.
B) Convert Avro data to JSON using a Kafka Streams application before ingestion. Use Snowpipe to ingest the JSON data to a VARIANT column and then process it using Snowpark DataFrames.
C) Use Snowpipe to ingest the Avro data to a raw table stored as binary. Then, use a Snowpark Python UDF with an Avro deserialization library to convert the binary data to a Snowpark DataFrame.
D) Create a Kafka connector that directly writes Avro data to a Snowflake table. Then, use Snowpark DataFrames to read and transform the data from that table.
E) Create external functions to pull the Avro data into a Snowflake stage and then read the data with Snowpark DataFrames for transformation.

4. A data engineer is implementing a data governance policy that requires masking PII data in non-production environments. They have identified a column 'CUSTOMER EMAIL' that needs to be masked. They want to use dynamic data masking in Snowflake, but the 'CUSTOMER EMAIL' column is referenced in several views. Which of the following approaches is MOST appropriate and avoids breaking the existing views?

A) Create a masking policy directly on the 'CUSTOMER EMAIL' column in the base table. This will automatically apply the masking to all views referencing the column.
B) Create masking policies on each of the individual views that reference the 'CUSTOMER EMAIL' column, using the same masking function.
C) Create a masking policy on the base table, but exclude the role used by the views from the policy's condition. This will prevent masking for those specific views.
D) Create a separate view that applies the masking function to the 'CUSTOMER EMAIL' column. Replace all existing views with the new masked view.
E) Create a masking policy on the base table but use a context function in the masking policy condition to check the database name. Mask the data only when the database name is the non-production database.

5. A data engineer is responsible for maintaining a Snowflake data warehouse. They notice a significant slowdown in the performance of a specific query that aggregates data from a table called 'SALES DATA', which contains billions of rows. The query is used for generating daily sales reports. The engineer suspects that the issue might be related to clustering. How would you diagnose the effectiveness of the clustering on the 'SALES DATA' table and identify potential improvements?

A) Use the SYSTEM$CLUSTERING_INFORMATION' function to analyze the clustering depth of the table. A high clustering depth indicates poor clustering.
B) Use the 'DESCRIBE TABLE SALES_DATA' command and check the 'clustering_key' property, then run 'SELECT SYSTEM$MEASURE CLUSTERING DEPTH('SALES to check the average depth of the table. Compare the clustering depth to the number of micro- partitions to assess clustering effectiveness. A depth closer to zero is best.
C) Examine the query profile in the Snowflake web interface to identify stages that are scanning large amounts of data. Check if these stages are benefiting from clustering.
D) Use the 'SHOW TABLES command to view the clustering key defined on the table. Verify that the clustering key is appropriate for the query workload.
E) Use the 'VALIDATE table command. This command detects fragmentation in the data due to poor clustering.
