Snowflake COF-C02 Exam - Topic 6 Question 18 Discussion

Actual exam question for Snowflake's COF-C02 exam
Question #: 18
Topic #: 6
[All COF-C02 Questions]

Which types of subqueries does Snowflake support? (Select TWO).

Show Suggested Answer Hide Answer
Suggested Answer: B

According to the Snowflake documentation1, a directory table stores a catalog of staged files in cloud storage and can be queried to retrieve theSnowflake-hosted file URLto each file in the stage. A file URL has the following format:

https:///api/files/<db_name>.<schema_name>.<stage_name>/<relative_path>

Based on this information, I think the query that contains a Snowflake hosted file URL in a directory table for a stage named bronzestage isB. select * from directory(@bronzestage);

Okay, I've got this. The key is to identify the two correct options from the list. I'll start by eliminating the ones I'm sure are wrong.

I'm pretty confident on this one. The way I see it, organizations can't just offload all their compliance obligations to their CSPs. They have to maintain some level of oversight and accountability, even if the day-to-day responsibility is delegated. I'll go with Option A.

When in doubt, I always try to eliminate options - 'general purchasing' seems too broad, and 'bid-splitting' sounds more like a result than a potential point of vulnerability.

Hmm, the packet was able to pass through the switch, so it must not have been able to detect the malware. I'm wondering if the encryption or fragmentation could be the reason.
