Snowflake ARA-C01 Practice Test - Questions Answers, Page 15

An Architect has a design where files arrive every 10 minutes and are loaded into a primary database table using Snowpipe. A secondary database is refreshed every hour with the latest data from the primary database.

Based on this scenario, what Time Travel query options are available on the secondary database?

An Architect for a multi-national transportation company has a system that is used to check the weather conditions along vehicle routes. The data is provided to drivers.

The weather information is delivered regularly by a third-party company and this information is generated as JSON structure. Then the data is loaded into Snowflake in a column with a VARIANT data type. This table is directly queried to deliver the statistics to the drivers with minimum time lapse.

A single entry includes (but is not limited to):

- Weather condition; cloudy, sunny, rainy, etc.

- Degree

- Longitude and latitude

- Timeframe

- Location address

- Wind

The table holds more than 10 years' worth of data in order to deliver the statistics from different years and locations. The amount of data on the table increases every day.

The drivers report that they are not receiving the weather statistics for their locations in time.

What can the Architect do to deliver the statistics to the drivers faster?

A new table and streams are created with the following commands:

CREATE OR REPLACE TABLE LETTERS (ID INT, LETTER STRING) ;

CREATE OR REPLACE STREAM STREAM_1 ON TABLE LETTERS;

CREATE OR REPLACE STREAM STREAM_2 ON TABLE LETTERS APPEND_ONLY = TRUE;

The following operations are processed on the newly created table:

INSERT INTO LETTERS VALUES (1, 'A');

INSERT INTO LETTERS VALUES (2, 'B');

INSERT INTO LETTERS VALUES (3, 'C');

TRUNCATE TABLE LETTERS;

INSERT INTO LETTERS VALUES (4, 'D');

INSERT INTO LETTERS VALUES (5, 'E');

INSERT INTO LETTERS VALUES (6, 'F');

DELETE FROM LETTERS WHERE ID = 6;

What would be the output of the following SQL commands, in order?

SELECT COUNT (*) FROM STREAM_1;

SELECT COUNT (*) FROM STREAM_2;

When loading data into a table that captures the load time in a column with a default value of either CURRENT_TIME () or CURRENT_TIMESTAMP () what will occur?

In a managed access schema, what are characteristics of the roles that can manage object privileges? (Select TWO).

An Architect is designing a data lake with Snowflake. The company has structured, semi-structured, and unstructured data. The company wants to save the data inside the data lake within the Snowflake system. The company is planning on sharing data among its corporate branches using Snowflake data sharing.

What should be considered when sharing the unstructured data within Snowflake?

Which Snowflake architecture recommendation needs multiple Snowflake accounts for implementation?

A company is designing its serving layer for data that is in cloud storage. Multiple terabytes of the data will be used for reporting. Some data does not have a clear use case but could be useful for experimental analysis. This experimentation data changes frequently and is sometimes wiped out and replaced completely in a few days.

The company wants to centralize access control, provide a single point of connection for the end-users, and maintain data governance.

What solution meets these requirements while MINIMIZING costs, administrative effort, and development overhead?

What is the MOST efficient way to design an environment where data retention is not considered critical, and customization needs are to be kept to a minimum?
