Snowflake ADA-C01 Exam - Topic 1 Question 15 Discussion

Actual exam question for Snowflake's ADA-C01 exam

Question #: 15
Topic #: 1

A Snowflake customer is experiencing higher costs than anticipated while migrating their data warehouse workloads from on-premises to Snowflake. The migration

workloads have been deployed on a single warehouse and are characterized by a large number of small INSERTs rather than bulk loading of large extracts. That single

warehouse has been configured as a single cluster, 2XL because there are many parallel INSERTs that are scheduled during nightly loads.

How can the Administrator reduce the costs, while minimizing the overall load times, for migrating data warehouse history?

AThere should be another 2XL warehouse deployed to handle a portion of the load queries.

BThe 2XL warehouse should be changed to 4XL to increase the number of threads available for parallel load queries.

CThe warehouse should be kept as a SMALL or XSMALL and configured as a multi-cluster warehouse to handle the parallel load queries.

DThe INSERTS should be converted to several tables to avoid contention on large tables that slows down query processing.

Show Suggested Answer

Suggested Answer: D

The SIMULATED_DATA_SHARING_CONSUMER session parameter allows a data provider to test the integrity of secure views based on the account that is accessing that view2. By setting this parameter to the name of the consumer account, the data provider can query the secure view and see the results that a user in the consumer account will see2. This helps to ensure that sensitive data in a shared database is not exposed to unauthorized users1. The other options are not valid session parameters in Snowflake3

Not sure about converting to several tables, that could complicate things.

Keeping it SMALL or XSMALL sounds like a smart move for cost savings.

Surprised they didn't consider splitting the INSERTs into smaller batches!

A multi-cluster setup could really help with those parallel loads.

I vaguely recall something about reducing contention by splitting INSERTs across multiple tables, which might relate to option D, but I’m not sure how that affects overall load times.

I’m leaning towards option C because it seems like a good way to balance cost and performance, but I’m not completely confident about the multi-cluster setup.

I think option B sounds tempting, but increasing to a 4XL might just drive costs up even more. I feel like we practiced a similar scenario where smaller warehouses were more efficient.

I remember we discussed how using a multi-cluster warehouse could help with parallel processing, but I'm not sure if keeping it small is the best approach.

I'm a little confused by this question. On one hand, I don't want to ignore Ethel's question completely. But if it's completely irrelevant, I'm not sure it's the best use of class time. I'm leaning towards option C - politely explain that we need to stick to the subject matter.
