Snowflake SnowPro Advanced Administrator ADA-C02 Sample Questions (Q39-Q44):

NEW QUESTION # 39
What are benefits of creating and maintaining resource monitors in Snowflake? (Choose three.)

A. Resource monitors can be applied to more than one virtual warehouse.
B. Resource monitor governance is tightly controlled and monitors can only be created by the ACCOUNTADMIN role or users with the CREATE MONITOR privilege.
C. Multiple resource monitors can be applied to a single virtual warehouse.
D. Resource monitors add no additional load to virtual warehouse compute.
E. The cost of running a resource monitor is only 10% of a credit, per day of operation.
F. Multiple triggers can be configured across various virtual warehouse thresholds.

Answer: A,C,F

Explanation:
Multiple resource monitors can be assigned to a single virtual warehouse for granular credit control.
Resource monitors support multiple triggers at different usage thresholds.
A single resource monitor can govern multiple virtual warehouses.

NEW QUESTION # 40
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 table is not big enough to take advantage of the clustering key.
B. The cardinality of the stores to transaction count ratio is too low to use the STORE_ID as a clustering key.
C. Sales across stores are not uniformly distributed.
D. The STORE_ID should be numeric.

Answer: C

Explanation:
Clustering is effective when data distribution across the clustering key is relatively uniform. In this case, most transactions are concentrated in only 20 of the 1000 stores, leading to skewed data distribution. This imbalance causes poor pruning, since large portions of micro-partitions still need to be scanned, even for queries targeting specific stores.

NEW QUESTION # 41
A Snowflake Administrator needs to persist all virtual warehouse configurations for auditing and backups. Given a table already exists with the following schema:
Table Name: VWH_META
Column 1: SNAPSHOT_TIME TIMESTAMP_NTZ
Column 2: CONFIG VARIANT
Which commands should be executed to persist the warehouse data at the time of execution in JSON format in the table VWH_META?

A. SHOW WAREHOUSES;
INSERT INTO VWH_META
SELECT CURRENT_TIMESTAMP(),
OBJECT_CONSTRUCT(*)
FROM TABLE(RESULT_SCAN(LAST_QUERY_ID()));
B. SHOW WAREHOUSES;
INSERT INTO VWH_META
SELECT CURRENT_TIMESTAMP(), *
FROM TABLE(RESULT_SCAN(SELECT LAST_QUERY_ID(-1)));
C. SHOW WAREHOUSES;
INSERT INTO VWH_META
SELECT CURRENT_TIMESTAMP(), *
FROM TABLE(RESULT_SCAN(LAST_QUERY_ID()));
D. SHOW WAREHOUSES;
INSERT INTO VWH_META
SELECT CURRENT_TIMESTAMP(),
FROM TABLE(RESULT_SCAN(LAST_QUERY_ID(1)));

Answer: A

Explanation:
To persist warehouse configurations in JSON format, the result set from SHOW WAREHOUSES must be captured and converted into a variant object. Using OBJECT_CONSTRUCT(*) with RESULT_SCAN(LAST_QUERY_ID()) stores the full warehouse configuration snapshot as JSON in the CONFIG VARIANT column, along with the timestamp.

NEW QUESTION # 42
Which command can temporarily disable Multi-factor Authentication (MFA) for the Snowflake username user1 for 24 hours?

A. alter user user1 set TEMPORARY_MFA_BYPASS=1440;
B. alter user user1 set HOURS_TO_BYPASS_MFA=24;
C. alter user user1 set DISABLE_MFA=1440;
D. alter user user1 set MINS_TO_BYPASS_MFA=1440;

Answer: D

Explanation:
The parameter MINS_TO_BYPASS_MFA controls how long MFA is bypassed for a user. Setting it to 1440 minutes (24 hours) temporarily disables MFA for that duration without revoking the user's MFA enrollment.

NEW QUESTION # 43
What access control policy will be put into place when future grants are assigned to both database and schema objects?

A. An access policy combining both the database object and the schema object will be used, with the most permissive policy taking precedence.
B. Schema privileges will take precedence over database privileges.
C. An access policy combining both the database object and the schema object will be used, with the most restrictive policy taking precedence.
D. Database, privileges will take precedence over schema privileges.

Answer: B

Explanation:
When future grants are set at both the database and schema levels, schema-level future grants take precedence over database-level grants for objects created within that schema.
