質問 # 67
You ran the below query. I have a warehouse with auto suspend set at 5 seconds
SELECT * FROM INVENTORY;
The query profile looks like as below. Please see below 'Percentage scanned from cache' is 0%
You ran the query again before 5 seconds has elapsed and the query profile looks as below. Look at the 'Percentage scanned for cache', it is 75%
You ran the query again after 5 seconds. The query profile looks as below. Look at the 'Percentage scanned from cache', it is zero again.
Why is this happening?
- A. The second run of the query used data cache to retrieve part of the result since it ran before the warehouse was suspended
- B. The second run of the query used query result cache
- C. The third run of the query used query result cache
正解：A
質問 # 68

質問 # 74
You have a medium warehouse with auto suspend of 5 minutes. You ran a query on table#1. After 10 minutes, you ran a query that joins table#1 and table#2, but you see that the query did not use data
cache.
Why?
- A. When a warehouse is suspended, it may lose its data cache
- B. The query that ran the second time is completely different from query that ran on table#1, hence it will not be able to use data cache
- C. Joins cannot use any type of cache
正解：A
質問 # 75
A table contains five columns and it has millions of records. The cardinality distribution of the columns is shown below:
Column C4 and C5 are mostly used by SELECT queries in the GROUP BY and ORDER BY clauses. Whereas columns C1, C2 and C3 are heavily used in filter and join conditions of SELECT queries.

Based on Snowflake recommendations, how should the clustering key columns be ordered while defining the multi-column clustering key?
- A. C2, C1, C3
- B. C5, C4, C2
- C. C3, C4, C5
- D. C1, C3, C2
正解：A
