[Q143-Q167] --------------------------------------------------- [UPDATED 2024] Getting COF-C02 Certification Made Easy! COF-C02 Exam Crack Test Engine Dumps Training With 697 Questions NEW QUESTION 143What is the MINIMUM permission needed to access a file URL from an external stage?  MODIFY  READ  SELECT  USAGE NEW QUESTION 144Which native data types are used for storing semi-structured data in Snowflake? (Select TWO)  NUMBER  OBJECT  STRING  VARCHAR  VARIANT Snowflake supports semi-structured data types, which include OBJECT and VARIANT. These data types are capable of storing JSON-like data structures, allowing for flexibility in data representation. OBJECT can directly contain VARIANT, and thus indirectly contain any other data type, including itself1.NEW QUESTION 145What type of query benefits the MOST from search optimization?  A query that uses only disjunction (i.e., OR) predicates  A query that includes analytical expressions  A query that uses equality predicates or predicates that use IN  A query that filters on semi-structured data types Search optimization in Snowflake is designed to improve the performance of queries that are selective and involve point lookup operations using equality and IN predicates. It is particularly beneficial for queries that access columns with a high number of distinct values1.References = [COF-C02] SnowPro Core Certification Exam Study Guide, Snowflake DocumentationNEW QUESTION 146Which Snowflake layer is associated with virtual warehouses?  Cloud services  Query processing  Elastic memory  Database storage NEW QUESTION 147A user needs to MINIMIZE the cost of large tables that are used to store transitory data. The data does not need to be protected against failures, because the data can be reconstructed outside of Snowflake.What table type should be used?  Permanent  Transient  Temporary  Externa For minimizing the cost of large tables that are used to store transitory data, which does not need to be protected against failures because it can be reconstructed outside of Snowflake, the best table type to use is Transient. Transient tables in Snowflake are designed for temporary or transitory data storage and offer reduced storage costs compared to permanent tables. However, unlike temporary tables, they persist across sessions until explicitly dropped.* Why Transient Tables: Transient tables provide a cost-effective solution for storing data that is temporary but needs to be available longer than a single session. They have lower data storage costs because Snowflake does not maintain historical data (Time Travel) for as long as it does for permanent* tables.* Creating a Transient Table:* To create a transient table, use the TRANSIENT keyword in the CREATE TABLE statement:CREATE TRANSIENT TABLE my_transient_table (…);* Use Case Considerations: Transient tables are ideal for scenarios where the data is not critical, can be easily recreated, and where cost optimization is a priority. They are suitable for development, testing, or staging environments where data longevity is not a concern.Reference: For more details on transient tables and their usage scenarios, refer to the Snowflake documentation on table types: https://docs.snowflake.com/en/sql-reference/sql/create-table.html#table-typesNEW QUESTION 148What are the responsibilities of Snowflake’s Cloud Service layer? (Choose three.)  Authentication  Resource management  Virtual warehouse caching  Query parsing and optimization  Query execution  Physical storage of micro-partitions NEW QUESTION 149What is the purpose of using the OBJECT_CONSTRUCT function with me COPY INTO command?  Reorder the rows in a relational table and then unload the rows into a file  Convert the rows in a relational table lo a single VARIANT column and then unload the rows into a file.  Reorder the data columns according to a target table definition and then unload the rows into the table.  Convert the rows in a source file to a single variant column and then load the rows from the file to a variant table. NEW QUESTION 150Which table function is used to perform additional processing on the results of a previously-run query?  QUERY_HISTORY  RESULT_SCAN  DESCRIBE_RESULTS  QUERY HISTORY BY SESSION TheRESULT_SCANtable function is used in Snowflake to perform additional processing on the results of a previously-run query. It allows users to reference the result set of a previous query by its query ID, enabling further analysis or transformations without re-executing the original query.References:* Snowflake Documentation: RESULT_SCANNEW QUESTION 151For the ALLOWED VALUES tag property, what is the MAXIMUM number of possible string values for a single tag?  10  50  64  256 NEW QUESTION 152What is the minimum Snowflake edition needed for database failover and fail-back between Snowflake accounts for business continuity and disaster recovery?  Standard  Enterprise  Business Critical  Virtual Private Snowflake The minimum Snowflake edition required for database failover and fail-back between Snowflake accounts for business continuity and disaster recovery is the Business Critical edition. References: Snowflake Documentation3.NEW QUESTION 153What is the purpose of a Query Profile?  To profile how many times a particular query was executed and analyze its u^age statistics over time.  To profile a particular query to understand the mechanics of the query, its behavior, and performance.  To profile the user and/or executing role of a query and all privileges and policies applied on the objects within the query.  To profile which queries are running in each warehouse and identify proper warehouse utilization and sizing for better performance and cost balancing. The purpose of a Query Profile is to provide a detailed analysis of a particular query’s execution plan, including the mechanics, behavior, and performance. It helps in identifying potential performance bottlenecks and areas for optimizationNEW QUESTION 154Which columns are part of the result set of the Snowflake LATERAL FLATTEN command? (Choose two.)  CONTENT  PATH  BYTE_SIZE  INDEX  DATATYPE NEW QUESTION 155Which data types are supported by Snowflake when using semi-structured data? (Choose two.)  VARIANT  VARRAY  STRUCT  ARRAY  QUEUE NEW QUESTION 156Which command can be used to load data into an internal stage?  LOAD  copy  GET  PUT https://medium.com/@divyanshsaxenaofficial/snowflake-loading-unloading-of-data-part-1-internal-stages-7121cc3cc9NEW QUESTION 157Which of the following describes how multiple Snowflake accounts in a single organization relate to various cloud providers?  Each Snowflake account can be hosted in a different cloud vendor and region.  Each Snowflake account must be hosted in a different cloud vendor and region  All Snowflake accounts must be hosted in the same cloud vendor and region  Each Snowflake account can be hosted in a different cloud vendor, but must be in the same region. Snowflake’s architecture allows for flexibility in account hosting across different cloud vendors and regions.This means that within a single organization, different Snowflake accounts can be set up in various cloud environments, such as AWS, Azure, or GCP, and in different geographical regions. This allows organizations to leverage the global infrastructure of multiple cloud providers and optimize their data storage and computing needs based on regional requirements, data sovereignty laws, and other considerations.https://docs.snowflake.com/en/user-guide/intro-regions.htmlNEW QUESTION 158Which of the following describes how multiple Snowflake accounts in a single organization relate to various cloud providers?  Each Snowflake account can be hosted in a different cloud vendor and region.  Each Snowflake account must be hosted in a different cloud vendor and region  All Snowflake accounts must be hosted in the same cloud vendor and region  Each Snowflake account can be hosted in a different cloud vendor, but must be in the same region. NEW QUESTION 159True or False: Snowpipe via REST API can only reference External Stages as source.  True  False Reference: https://community.snowflake.com/s/article/Making-Transient-table-by-DefaultNEW QUESTION 160Which feature is integrated to support Multi-Factor Authentication (MFA) at Snowflake?  Authy  Duo Security  One Login  RSA SecurlD Access NEW QUESTION 161What activities can a user with the ORGADMIN role perform? (Select TWO).  Create an account for an organization.  Edit the account data for an organization.  Delete the account data for an organization.  View usage information for all accounts in an organization.  Select all the data in tables for all accounts in an organization. The ORGADMIN role in Snowflake is an organizational-level role that provides administrative capabilities across the entire organization, rather than being limited to a single Snowflake account. Users with this role can:* A. Create an account for an organization: The ORGADMIN role has the privilege to create new Snowflake accounts within the organization, allowing for the expansion and management of the organization’s resources.* D. View usage information for all accounts in an organization: This role also has access to comprehensive usage and activity data across all accounts within the organization. This is crucial for monitoring, cost management, and optimization at the organizational level.References:* Snowflake Documentation: Understanding Role-Based Access ControlNEW QUESTION 162Which of the following connectors allow Multi-Factor Authentication (MFA) authorization when connecting? (Choose all that apply.)  JDBC  SnowSQL  Snowflake Web Interface (UI)  ODBC  Python NEW QUESTION 163True or False: All Snowflake table types include fail-safe storage.  True  False NEW QUESTION 164Which of the following accurately represents how a table fits into Snowflake’s logical container hierarchy?  Account -> Schema -> Database -> Table  Account -> Database -> Schema -> Table  Database -> Schema -> Table -> Account  Database -> Table -> Schema -> Account NEW QUESTION 165While running a query on a virtual warehouse in auto-scale mode, additional clusters are stated immediately if which setting is configured?         NEW QUESTION 166True or False: When active, a pipe requires a dedicated Virtual Warehouse to execute.  True  False NEW QUESTION 167A table needs to be loaded. The input data is in JSON format and is a concatenation of multiple JSON documents. The file size is 3 GB. A warehouse size small is being used. The following COPY INTO command was executed:COPY INTO SAMPLE FROM @~/SAMPLE.JSON (TYPE=JSON)The load failed with this error:Max LOB size (16777216) exceeded, actual size of parsed column is 17894470.How can this issue be resolved?  Compress the file and load the compressed file.  Split the file into multiple files in the recommended size range (100 MB – 250 MB).  Use a larger-sized warehouse.  Set STRIP_OUTER_ARRAY=TRUE in the COPY INTO command. The error “Max LOB size (16777216) exceeded” indicates that the size of the parsed column exceeds the maximum size allowed for a single column value in Snowflake, which is 16 MB. To resolve this issue, the file should be split into multiple smaller files that are within the recommended size range of 100 MB to 250 MB.This will ensure that each JSON document within the files is smaller than the maximum LOB size allowed.Compressing the file, using a larger-sized warehouse, or setting STRIP_OUTER_ARRAY=TRUE will not resolve the issue of the column size exceeding the maximum allowed.
