Snowflake Exam ARA-R01 Topic 1 Question 10 Discussion

Actual exam question for Snowflake's ARA-R01 exam

Question #: 10
Topic #: 1

A Snowflake Architect Is working with Data Modelers and Table Designers to draft an ELT framework specifically for data loading using Snowpipe. The Table Designers will add a timestamp column that Inserts the current tlmestamp as the default value as records are loaded into a table. The Intent is to capture the time when each record gets loaded into the table; however, when tested the timestamps are earlier than the loae_take column values returned by the copy_history function or the Copy_HISTORY view (Account Usage).

Why Is this occurring?

AThe timestamps are different because there are parameter setup mismatches. The parameters need to be realigned

BThe Snowflake timezone parameter Is different from the cloud provider's parameters causing the mismatch.

CThe Table Designer team has not used the localtimestamp or systimestamp functions in the Snowflake copy statement.

DThe CURRENT_TIMEis evaluated when the load operation is compiled in cloud services rather than when the record is inserted into the table.

Suggested Answer: D

Using Snowpipe for continuous, automated data ingestion minimizes the need for manual intervention and ensures that data is available in Snowflake promptly after it is generated. Leveraging Snowflake's data sharing capabilities allows for efficient and secure access to the vendor's data without the need for complex API integrations. Materialized views provide pre-aggregated data for fast access, which is ideal for dashboards that require high performance1234.

The timestamps are definitely different due to parameter setup mismatches. The Snowflake team needs to align the parameters properly to get the correct timestamps.
