Snowflake SnowPro Advanced Administrator ADA-C02 Sample Questions (Q13-Q18):

NEW QUESTION # 13
Which function is the role SECURITYADMIN responsible for that is not granted to role USERADMIN?

A. Manage system grants
B. Reset a Snowflake user's password
C. Create new roles
D. Create new users

Answer: A

Explanation:
The SECURITYADMIN role is responsible for managing system grants, such as granting or revoking privileges on roles, which is not permitted for the USERADMIN role.

NEW QUESTION # 14
A team of developers created a new schema for a new project. The developers are assigned the role DEV_TEAM which was set up using the following statements:
USE ROLE SECURITYADMIN;
CREATE ROLE DEV_TEAM;
GRANT USAGE, CREATE SCHEMA ON DATABASE DEV_DB01 TO ROLE DEV_TEAM;
GRANT USAGE ON WAREHOUSE DEV_WH TO ROLE DEV_TEAM;
Each team member's access is set up using the following statements:
USE ROLE SECURITYADMIN;
CREATE ROLE JDOE_PROFILE;
CREATE USER JDOE LOGIN_NAME = 'JDOE' DEFAULT ROLE='JDOE_PROFILE';
GRANT ROLE JDOE_PROFILE TO USER JDOE;
GRANT ROLE DEV_TEAM TO ROLE JDOE_PROFILE;
New tables created by any of the developers are not accessible by the team as a whole.
How can an Administrator address this problem?

A. Assign ownership privilege to DEV_TEAM on the newly-created schema.
B. Set up the new schema as a managed-access schema.
C. Assign usage privilege on the virtual warehouse DEV_WH to the role JDOE_PROFILE.
D. Set up future grants on the newly-created schemas.

Answer: D

Explanation:
Future grants allow privileges to be automatically granted on objects created in the future within a schema. By configuring future grants on the schema, privileges such as SELECT can automatically be granted to the DEV_TEAM role whenever new tables are created. This ensures that all developers using the DEV_TEAM role can access newly created tables without requiring manual privilege grants after each table creation.

NEW QUESTION # 15
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? (Choose two.)

A. 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.
B. Increase the multi-cluster maximum to 20 or more clusters.
C. Have the group running the complex monthly queries use a separate appropriately-sized warehouse to support their workload.
D. Increase the minimum number of clusters started in the multi-cluster configuration to 5.
E. Examine the complex queries and determine if they can be made more efficient using clustering keys or materialized views.

Answer: C,E

Explanation:
The best way to handle the once-a-month complex workload is to use a separate, appropriately-sized warehouse dedicated to that workload and to optimize the complex queries with techniques like clustering keys or materialized views. These approaches resolve queueing and performance issues without overspending on always running more clusters.

NEW QUESTION # 16
A company has many users in the role ANALYST who routinely query Snowflake through a reporting tool. The Administrator has noticed that the ANALYST users keep two small clusters busy all of the time, and occasionally they need three or four clusters of that size.
Based on this scenario, how should the Administrator set up a virtual warehouse to MOST efficiently support this group of users?

A. Create a standard X-Large warehouse, which is equivalent to four small clusters. Set the warehouse to auto-resume and auto-suspend, and give USAGE privileges to the ANALYST role.
B. Create a multi-cluster warehouse with MIN_CLUSTERS set to 1. Give MANAGE privileges to the ANALYST role so this group can start and stop the warehouse, and increase the number of clusters as needed.
C. Create a multi-cluster warehouse with MIN_CLUSTERS set to 2. Set the warehouse to auto-resume and auto-suspend, and give USAGE privileges to the ANALYST role. Allow the warehouse to auto-scale.
D. Create four virtual warehouses (sized Small through XL) and set them to auto-suspend and auto-resume. Have users in the ANALYST role select the appropriate warehouse based on how many queries are being run.

Answer: C

Explanation:
A multi-cluster warehouse with MIN_CLUSTERS = 2 matches typical usage, while auto-suspend and auto-resume ensure resources are only used when needed. Allowing auto-scaling handles peak periods efficiently, and giving USAGE (not MANAGE) to ANALYST users is secure and appropriate.

NEW QUESTION # 17
What Snowflake capabilities are commonly used in rollback scenarios? (Choose two.)

A. CREATE TABLE prd_table_bkp as SELECT * from table(result_scan('problematic_query_id'));
B. SELECT SYSTEM$CANCEL_QUERY('problematic_query_id');
C. CREATE TABLE prd_table_bkp CLONE prd_table BEFORE (STATEMENT => 'problematic_query_id');
D. ALTER TABLE prd_table SWAP WITH prd_table_bkp;
E. Contact Snowflake Support to retrieve Fail-safe data.

Answer: C,D

Explanation:
Creating a clone of a table at a point in time before a problematic statement uses Snowflake Time Travel to restore the table’s previous state without copying data. This allows recovery of the table as it existed before the issue occurred.
Swapping tables enables a fast rollback by exchanging the original production table with the restored backup table. This operation is metadata-only and allows immediate restoration of the previous version of the data with minimal downtime.
