Snowflake COF-C02 Exam - Topic 2 Question 63 Discussion

Actual exam question for Snowflake's COF-C02 exam
Question #: 63
Topic #: 2
[All COF-C02 Questions]

What are common issues found by using the Query Profile? (Choose two.)

Show Suggested Answer Hide Answer
Suggested Answer: D, E

The Query Profile in Snowflake is used to identify performance issues with queries. Common issues that can be found using the Query Profile include identifying inefficient micro-partition pruning (D) and data spilling to a local or remote disk (E).Micro-partition pruning is related to the efficiency of query execution, and data spilling occurs when the memory is insufficient, causing the query to write data to disk, which can slow down the query performance1.

Haha, I remember the time I tried to optimize a query and ended up crashing the entire system. The Query Profile would have been really useful back then!

E is also a common issue found by using the Query Profile. Data spilling to disk can be a major performance bottleneck.

I remember practicing a question similar to this, and I think B is also a strong candidate since high credit consumption is a big deal.

I'm a bit confused on this one. I know the Query Profile is useful for troubleshooting, but I'm not totally clear on the specific issues it can identify. I think I'd just go with my best guesses on A and B.

The Query Profile is all about optimizing query performance, so I'd go with A and E. Slow queries and data spilling are definitely the key things to look for.

A and D are the correct answers. The Query Profile helps identify slow-running queries and inefficient micro-partition pruning.

Hmm, I'm not sure about C and D. Logical issues and micro-partition pruning don't seem like the main things the Query Profile is for. I'd focus on the performance-related options.

I think I'd start by looking at options A and B. The Query Profile is probably good for identifying slow-running queries and high-credit consumers.
