In the provided exhibit, Warehouse 2 is under Resource Monitor 2, which has a credit quota of 1000 credits.
However, it's important to note that warehouses can also draw from the account-level resource monitor if they consume their dedicated monitor's quota. In this exhibit, Resource Monitor 1 is set for the account with a credit quota of 500 credits.
The exhibit does not clearly show whether Warehouse 2 is also subject to the account-level Resource Monitor
1, but if we assume the typical case where all warehouses can draw from the account-level monitor, the maximum limit of credits Warehouse 2 can consume would be the sum of its dedicated resource monitor (Resource Monitor 2) and the account-level resource monitor (Resource Monitor 1).
Thus, Warehouse 2 can consume:
* 1000 credits from Resource Monitor 2
* 500 credits from Resource Monitor 1 (if applicable)
This gives a total of 1500 credits. Therefore, the maximum credit limit that Warehouse 2 can consume, taking into account the possibility of the account-level monitor's contribution, would be 1500 credits.
However, without explicit confirmation that Warehouse 2 can use credits from Resource Monitor 1, one would default to the specific resource monitor assigned to the warehouse, which is 1000 credits. Given the available options, the closest and most accurate answer is B. 1500, as it represents the sum of credits from both monitors that potentially apply to Warehouse 2.

Snowflake is designed to optimize query performance by utilizing metadata for certain types of queries.
When executing a COUNT query, Snowflake can often fulfill the request by accessing metadata about the table's row count, rather than scanning the entire table or micro-partitions. This is particularly efficient for large tables like FCT_SALES with a significant number of records. The metadata layer maintains statistics about the table, including the row count, which enables Snowflake to quickly return the result of a COUNT query without the need to perform a full scan.
