Snowflake DSA-C02 Exam - Topic 1 Question 51 Discussion

Actual exam question for Snowflake's DSA-C02 exam

Question #: 51
Topic #: 1

Mark the incorrect statement regarding usage of Snowflake Stream & Tasks?

ASnowflake automatically resizes and scales the compute resources for serverless tasks.

BSnowflake ensures only one instance of a task with a schedule (i.e. a standalone task or the root task in a DAG) is executed at a given time. If a task is still running when the next scheduled execution time occurs, then that scheduled time is skipped.

CStreams support repeatable read isolation.

DAn standard-only stream tracks row inserts only.

Show Suggested Answer

Suggested Answer: D

All are correct except a standard-only stream tracks row inserts only.

A standard (i.e. delta) stream tracks all DML changes to the source object, including inserts, up-dates, and deletes (including table truncates).

Streams with repeatable read isolation? Sounds like a party I want to be at!

Option B is correct. Snowflake ensures only one instance of a scheduled task is executed at a time.

Snowflake's serverless tasks are pretty cool, but I heard they can be a bit of a diva and demand their own private jet.

Option D is incorrect. A standard-only stream tracks both inserts and updates.

I’m pretty confident that option A is true because I remember reading about Snowflake's automatic scaling for serverless tasks.

I have a vague recollection that standard-only streams track more than just inserts, so maybe option D is the one that's incorrect?

I remember practicing a question about task execution, and I think option B is correct since it mentions skipping the scheduled time if a task is still running.

I think option C might be the incorrect one, but I'm not entirely sure about the isolation levels in Snowflake.

I've got this! The incorrect statement is B. Snowflake does not skip the scheduled execution time if a task is still running - it will queue the next run instead.

Okay, let me think this through. I know tasks automatically scale the compute resources, and that tasks are scheduled to run at specific times. I think the tricky part here is understanding the behavior when a task is still running when the next scheduled execution occurs.

Hmm, I'm a bit confused on the difference between streams and tasks. I'll need to review my notes to make sure I understand the correct usage of each.

I'm pretty sure the incorrect statement is D. An standard-only stream tracks row inserts, updates, and deletes, not just inserts.
