質問 1：
A retailer uses a TRANSACTIONS table (100M rows, 1.2 TB) that has been clustered by the STORE_ID column (varchar(50)). The vast majority of analyses on this table are grouped by STORE_ID to look at store performance.
There are 1000 stores operated by the retailer but most sales come from only 20 stores. The Administrator notes that most queries are currently experiencing poor pruning, with large amounts of bytes processed by even simple queries.
Why is this occurring?
A. The STORE_ID should be numeric.
B. Sales across stores are not uniformly distributed.
C. The cardinality of the stores to transaction count ratio is too low to use the STORE_ID as a clustering key.
D. The table is not big enough to take advantage of the clustering key.

質問 5：
An Administrator receives data from a Snowflake partner. The partner is sharing a dataset that contains multiple secure views. The Administrator would like to configure the data so that only certain roles can see certain secure views.
How can this be accomplished?
A. Apply RBAC directly onto the partner's shared secure views.
B. Create views over the incoming shared database and apply the desired RBAC onto these views.
C. Clone the data and insert it into a company-owned share and apply the desired RBAC on the new tables.
D. Individually grant imported privileges onto the schema in the share.

質問 6：
A Snowflake Administrator has a multi-cluster virtual warehouse and is using the Snowflake Business Critical edition. The minimum number of clusters is set to 2 and the maximum number of clusters is set to 10. This configuration works well for the standard workload, rarely exceeding 5 running clusters. However, once a month the Administrator notes that there are a few complex long-running queries that are causing increased queue time and the warehouse reaches its maximum limit at 10 clusters.
Which solutions will address the issues happening once a month? (Select TWO).
A. Examine the complex queries and determine if they can be made more efficient using clustering keys or materialized views.
B. Have the group running the complex monthly queries use a separate appropriately-sized warehouse to support their workload.
C. Increase the minimum number of clusters started in the multi-cluster configuration to 5.
D. Increase the multi-cluster maximum to 20 or more clusters.
E. Use a task to increase the cluster size for the time period that the more complex queries are running and another task to reduce the size of the cluster once the complex queries complete.
正解：B,E
