Snowflake SnowPro Advanced Administrator ADA-C02 Sample Questions (Q32-Q37):

NEW QUESTION # 32
A large international company with many operating regions requires data to be shared bi-directionally among all offices (head office to regional offices and regional offices among themselves). This company is a Snowflake account holder with European operations deployed in Microsoft Azure (single region) while North American regional offices are using AWS (single region) as their deployment cloud. This setup is required to comply with Personal Identifiable Information (PII) regulations in some of the European countries. The corporate head office is in Europe.
How can this data be shared bi-directionally, while MINIMIZING costs?

A. Move all the Snowflake accounts to a single region, and implement data sharing.
B. Use the PUT command to move files to an Amazon S3 bucket and Azure Blobs, and use an external file management application to move files within the corporate VPC.
C. Use bi-directional data sharing among offices in the same region and replication among offices across the continents.
D. Use data replication everywhere to reduce costs associated with same-region sharing.

Answer: C

Explanation:
Direct data sharing is the most cost-efficient method when accounts are in the same region and cloud. For cross-continent or cross-cloud sharing, Snowflake requires replication. Combining both - data sharing within the same region and replication across continents - ensures compliance, minimizes costs, and enables bi-directional sharing.

NEW QUESTION # 33
An Administrator loads data into a staging table every day. Once loaded, users from several different departments perform transformations on the data and load it into different production tables.
How should the staging table be created and used to MINIMIZE storage costs and MAXIMIZE performance?

A. Create it as a temporary table with a retention time of 0 days.
B. Create it as a permanent table with a retention time of 0 days.
C. Create it as an external table, which will not incur Time Travel costs.
D. Create it as a transient table with a retention time of 0 days.

Answer: D

Explanation:
A transient table is best suited for staging because it avoids long-term storage costs by not maintaining Fail-safe and can have Time Travel retention set to 0 days. This minimizes storage costs while still providing performance comparable to permanent tables, making it the optimal choice for daily staging data.

NEW QUESTION # 34
What roles or security privileges will allow a consumer account to request and get data from the Data Exchange? (Choose two.)

A. IMPORT SHARE and CREATE DATABASE
B. SECURITYADMIN
C. SYSADMIN
D. IMPORT PRIVILEGES and SHARED DATABASE
E. ACCOUNTADMIN

Answer: A,E

Explanation:
ACCOUNTADMIN role is required to access and manage Data Exchange listings and shares.
The IMPORT SHARE and CREATE DATABASE privileges are required to create databases from shared data.

NEW QUESTION # 35
MY_TABLE is a table that has not been updated or modified for several days. On 01 January 2021 at 07:01, a user executed a query to update this table. The query ID is '8e5d0ca9-005e-44e6-b858-a8f5b37c5726'. It is now 07:30 on the same day.
Which queries will allow the user to view the historical data that was in the table before this query was executed? (Choose three.)

A. SELECT * FROM my_table AT(OFFSET => -60*30);
B. SELECT * FROM my_table BEFORE(STATEMENT => '8e5d0ca9-005e-44e6-b858-a8f5b37c5726');
C. SELECT * FROM TIME_TRAVEL('MY_TABLE', 2021-01-01 07:00:00);
D. SELECT * FROM my_table AT(TIMESTAMP => '2021-01-01 07:00:00'::timestamp);
E. SELECT * FROM my_table PRIOR TO STATEMENT '8e5d0ca9-005e-44e6-b858-a8f5b37c5726';
F. SELECT * FROM my_table WITH TIME TRAVEL(OFFSET => -60*30);

Answer: A,B,D

Explanation:
Use Time Travel to view past table versions: (B) selects the table "as of" 07:00 via AT(TIMESTAMP => ...); (E) selects "as of" 30 minutes earlier via AT(OFFSET => -60*30); (F) selects the state before the specified statement via BEFORE(STATEMENT => '<query_id>').

NEW QUESTION # 36
In general, the monthly billing for database replication is proportional to which variables? (Choose two.)

A. The number of times data moves across regions and/or cloud service providers between the primary and secondary database accounts
B. The frequency of changes to the primary database as a result of data loading or DML operations
C. The frequency of the secondary database refreshes from the primary database
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: C,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.
