Snowflake SnowPro Advanced Architect Certification Sample Questions (Q115-Q120):

NEW QUESTION # 115
An Architect has designed a data pipeline that Is receiving small CSV files from multiple sources. All of the files are landing in one location. Specific files are filtered for loading into Snowflake tables using the copy command. The loading performance is poor.
What changes can be made to Improve the data loading performance?

A. Change the file format from CSV to JSON.
B. Increase the size of the virtual warehouse.
C. Create a specific storage landing bucket to avoid file scanning.
D. Create a multi-cluster warehouse and merge smaller files to create bigger files.

Answer: D

NEW QUESTION # 116
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. Create an additional table in the schema for longitude and latitude. Determine a regular task to fill this information by extracting it from the JSON dataset.
B. Add search optimization service on the variant column for longitude and latitude in order to query the information by using specific metadata.
C. Divide the table into several tables for each location by using the location address information from the JSON dataset in order to process the queries in parallel.
D. Divide the table into several tables for each year by using the timeframe information from the JSON dataset in order to process the queries in parallel.

Answer: B

Explanation:
To improve the performance of queries on semi-structured data, such as JSON stored in a VARIANT column, Snowflake's search optimization service can be utilized. By adding search optimization specifically for the longitude and latitude fields within the VARIANT column, the system can perform point lookups and substring queries more efficiently. This will allow for faster retrieval of weather statistics, which is critical for the drivers to receive timely updates.

NEW QUESTION # 117
Following objects can be cloned in snowflake

A. Temporary table
B. External tables
C. Internal stages
D. Permanent table
E. Transient table

Answer: B,D,E

Explanation:
Explanation
* Snowflake supports cloning of various objects, such as databases, schemas, tables, stages, file formats, sequences, streams, tasks, and roles. Cloning creates a copy of an existing object in the system without copying the data or metadata. Cloning is also known as zero-copy cloning1.
* Among the objects listed in the question, the following ones can be cloned in Snowflake:
* Permanent table: A permanent table is a type of table that has a Fail-safe period and a Time Travel retention period of up to 90 days. A permanent table can be cloned using the CREATE TABLE ...
CLONE command2. Therefore, option A is correct.
* Transient table: A transient table is a type of table that does not have a Fail-safe period and can have a Time Travel retention period of either 0 or 1 day. A transient table can also be cloned using the CREATE TABLE ... CLONE command2. Therefore, option B is correct.
* External table: An external table is a type of table that references data files stored in an external location, such as Amazon S3, Google Cloud Storage, or Microsoft Azure Blob Storage. An external table can be cloned using the CREATE EXTERNAL TABLE ... CLONE command3.
Therefore, option D is correct.
* The following objects listed in the question cannot be cloned in Snowflake:
* Temporary table: A temporary table is a type of table that is automatically dropped when the session ends or the current user logs out. Temporary tables do not support cloning4. Therefore, option C is incorrect.
* Internal stage: An internal stage is a type of stage that is managed by Snowflake and stores files in Snowflake's internal cloud storage. Internal stages do not support cloning5. Therefore, option E is incorrect.

NEW QUESTION # 118
A Snowflake Architect is designing a multi-tenant application strategy for an organization in the Snowflake Data Cloud and is considering using an Account Per Tenant strategy.
Which requirements will be addressed with this approach? (Choose two.)

A. Storage costs must be optimized.
B. Tenant data shape may be unique per tenant.
C. Compute costs must be optimized.
D. Security and Role-Based Access Control (RBAC) policies must be simple to configure.
E. There needs to be fewer objects per tenant.

Answer: A,C

NEW QUESTION # 119
What does a Snowflake Architect need to consider when implementing a Snowflake Connector for Kafka?

A. The Kafka connector will create one table and one pipe to ingest data for each topic. If the connector cannot create the table or the pipe it will result in an exception.
B. The Kafka connector supports key pair authentication, OAUTH. and basic authentication (for example, username and password).
C. Every Kafka message is in JSON or Avro format.
D. The default retention time for Kafka topics is 14 days.

Answer: C
