Snowflake SnowPro Advanced Administrator ADA-C02 Sample Questions (Q40-Q45):

NEW QUESTION # 40
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. Increase the multi-cluster maximum to 20 or more clusters.
B. Have the group running the complex monthly queries use a separate appropriately-sized warehouse to support their workload.
C. 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.
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: B,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 # 41
When adding secure views to a share in Snowflake, which function is needed to authorize users from another account to access rows in a base table?

A. CURRENT CLIENT
B. CURRENT USER
C. CURRENT ACCOUNT
D. CURRENT ROLE

Answer: C

Explanation:
When building secure views for data sharing, the CURRENT_ACCOUNT function is used to identify and authorize the consuming account. This ensures that row-level security can be enforced per consumer account accessing the shared data.

NEW QUESTION # 42
In general, the monthly billing for database replication is proportional to which variables? (Choose two.)

A. The frequency of the secondary database refreshes from the primary database
B. The number of times data moves across regions and/or cloud service providers between the primary and secondary database accounts
C. The frequency of changes to the primary database as a result of data loading or DML operations
D. The amount of table data in the primary database that changes as a result of data loading or DML operations
E. The number and size of warehouses defined in the primary account

Answer: A,D

Explanation:
Replication billing is proportional to the amount of table data in the primary database that changes and needs to be replicated.
The frequency of secondary database refreshes determines how often changed data is transferred, directly impacting replication costs.

NEW QUESTION # 43
An Administrator has been asked to support the company's application team need to build a loyalty program for its customers. The customer table contains Personal Identifiable Information (PII), and the application team's role is DEVELOPER.
CREATE TABLE customer_data (
customer_first_name string,
customer_last_name string,
customer_address string,
customer_email string,
... some other columns,
);
The application team would like to access the customer data, but the email field must be obfuscated.
How can the Administrator protect the sensitive information, while maintaining the usability of the data?

A. Create a separate table for all the non-PII columns and grant the role DEVELOPER access to the new table.
B. Use the CURRENT_ROLE context function to integrate with a masking policy on the fields that contain sensitive data.
C. Use the CURRENT_ROLE and CURRENT_USER context functions to integrate with a secure view and filter the sensitive data.
D. Create a view on the customer_data table to eliminate the email column by omitting it from the SELECT clause. Grant the role DEVELOPER access to the view.

Answer: B

Explanation:
The correct approach is to apply a dynamic data masking policy on the sensitive customer_email column. Using the CURRENT_ROLE context function in the masking policy allows the Administrator to obfuscate the email for the DEVELOPER role while maintaining usability of the data for other authorized roles.

NEW QUESTION # 44
A Snowflake Administrator wants to create a virtual warehouse that supports several dashboards, issuing various queries on the same database.
For this warehouse, why should the Administrator consider setting AUTO_SUSPEND to 0 or NULL?

A. To keep the data cache warm to support good performance of similar queries
B. To save costs on warehouse shutdowns and startups for different queries
C. To keep the query result cache warm for good performance on repeated queries
D. To save costs by running the warehouse as little as possible

Answer: A

Explanation:
Setting AUTO_SUSPEND to 0 or NULL prevents the warehouse from suspending, which keeps the data cache warm. This improves performance for dashboards and workloads that frequently run similar queries, since the warehouse avoids cache loss from suspending and resuming.
