NEW QUESTION # 564
Revoking which privilege will prevent one role from giving privileges to other roles?
- A. USAGE
- B. MODIFY
- C. MANAGE GRANTS
- D. REFERENCES
Answer: C
Explanation:
The correct answer is D. MANAGE GRANTS .
The MANAGE GRANTS privilege allows a role to grant and revoke privileges on objects. If this privilege is revoked, the role loses the broad ability to manage privileges for other roles.
Why D is correct:
MANAGE GRANTS is a powerful global privilege. It allows a role to grant and revoke privileges, even on objects the role does not own, depending on Snowflake's access control rules.
Why the other options are incorrect:
A). USAGE allows access to an object or namespace, such as a database, schema, warehouse, or integration. It does not allow broad grant management.
B). MODIFY allows changes to certain object properties or data, depending on the object type, but it does not broadly allow granting privileges to roles.
C). REFERENCES is related to referencing objects, such as in constraints or policies. It does not control grant administration.
Official Snowflake documentation reference:
Snowflake documentation describes MANAGE GRANTS as the global privilege that enables granting and revoking privileges on objects.

NEW QUESTION # 565
What is the most efficient method to share a subset of data from a table with a consumer account?
- A. Create a secure User-Defined Function, or UDF.
- B. Create a secure view.
- C. Create an external table.
- D. Use a dynamic table.
Answer: B
Explanation:
The correct answer is D. Create a secure view .
A secure view is the recommended and efficient way to share a filtered subset of data with a consumer account using Snowflake Secure Data Sharing. The provider can define the rows and columns that should be visible, then share the secure view instead of sharing the full base table.
Why D is correct:
A secure view protects the view definition from unauthorized users and can be used to expose only selected rows or columns from an underlying table.
Example concept:
CREATE SECURE VIEW shared_sales_west AS
SELECT order_id, customer_id, amount, region
FROM sales
WHERE region = ' WEST ' ;
The provider can then include this secure view in a share, allowing the consumer to query only the approved subset of data.
Why the other options are incorrect:
A). A secure UDF can protect function logic, but it is not the most efficient method for sharing a subset of table data.
B). A dynamic table materializes transformation results, but it is not the standard method for secure data sharing with filtered access.
C). An external table allows querying data in external cloud storage. It is not the best method for sharing a subset of Snowflake table data.
Official Snowflake documentation reference:
Snowflake documentation explains that secure views are used with Secure Data Sharing when a provider wants to share filtered or restricted data while protecting the underlying query definition.
Reference: Snowflake Documentation - Secure Data Sharing; Snowflake Documentation - Secure views; SnowPro Core Study Guide - Data Protection and Governance.
NEW QUESTION # 566
A Snowflake user executed a query and received the results. Another user executed the same query 4 hours later. The data had not changed.
What will occur?
- A. No virtual warehouse will be used, data will be read from the result cache.
- B. The default virtual warehouse will be used to read all data.
- C. No virtual warehouse will be used, data will be read from the local disk cache.
- D. The virtual warehouse that is defined at the session level will be used to read all data.
Answer: A
Explanation:
Snowflake maintains a result cache that stores the results of every query for 24 hours.If the same query is executed again within this time frame and the data has not changed, Snowflake will retrieve the data from the result cache instead of using a virtual warehouse to recompute the results2.
NEW QUESTION # 567
How many credits does a size 3X-Large virtual warehouse consume if it runs continuously for 2 hours?
- A. 0
- B. 1
- C. 2
- D. 3
Answer: A
Explanation:
In Snowflake, the consumption of credits by a virtual warehouse is determined by its size and the duration for which it runs. A size 3X-Large virtual warehouse consumes 128 credits if it runs continuously for 2 hours.
This consumption rate is based on the principle that larger warehouses, capable of providing greater computational resources and throughput, consume more credits per hour of operation. The specific rate of consumption is defined by Snowflake's pricing model and the scale of the virtual warehouse.

NEW QUESTION # 568
What does Snowflake attempt to do if any of the compute resources for a virtual warehouse fail to provision during start-up?
- A. Provision the failed resources
- B. Restart failed resources.
- C. Queue the failed resources
- D. Repair the failed resources.
Answer: B
Explanation:
If any compute resources for a virtual warehouse fail to provision during startup, Snowflake will attempt to restart those failed resources. The system is designed to automatically handle transient issues that might occur during the provisioning of compute resources. By restarting the failed resources, Snowflake aims to ensure that the virtual warehouse has the necessary compute capacity to handle the user ' s workloads without manual intervention.

NEW QUESTION # 569
What can be used to process unstructured data?
- A. The copy into < table > command
- B. External tables
- C. Snowpipe
- D. External functions
Answer: D
Explanation:
To process unstructured data in Snowflake, external functions can be used.
External Functions: These allow you to call external services and processing engines from within Snowflake SQL. External functions can be used to handle complex processing tasks that are not natively supported by Snowflake, including those involving unstructured data.
Implementation: You define an external function in Snowflake that points to an external processing service (e.
g., AWS Lambda, Google Cloud Functions).

NEW QUESTION # 570
Which option will create a table without data from the CUSTOMERS table?
- A. CREATE OR REPLACE TEMP TABLE CUSTOMERS_CLONE (CLONE VARCHAR);
- B. CREATE TABLE CUSTOMERS_CLONE AS SELECT * FROM CUSTOMERS;
- C. CREATE TABLE CUSTOMERS_CLONE LIKE CUSTOMERS;
- D. CREATE TABLE CUSTOMERS_CLONE CLONE CUSTOMERS;
Answer: C
Explanation:
The correct answer is A. CREATE TABLE CUSTOMERS_CLONE LIKE CUSTOMERS; .
The CREATE TABLE ... LIKE command creates a new table with the same column definitions as an existing table, but it does not copy the data from the source table.
Why A is correct:
CREATE TABLE CUSTOMERS_CLONE LIKE CUSTOMERS; creates an empty table with the same structure as CUSTOMERS.
Why the other options are incorrect:
B). CREATE TABLE ... CLONE creates a zero-copy clone of the source table, including access to the source table's existing data at the time of cloning.
C). This creates a temporary table with one column named CLONE; it does not create a table based on the structure of CUSTOMERS.
D). CREATE TABLE ... AS SELECT creates a new table and inserts the result of the query, so it copies data from CUSTOMERS.
Official Snowflake documentation reference:
Snowflake documentation explains that CREATE TABLE ... LIKE creates a new table with the same column definitions as another table, but without copying data.
Reference: Snowflake Documentation - CREATE TABLE ... LIKE; Snowflake Documentation - CREATE TABLE ... CLONE; SnowPro Core Study Guide - SQL and Snowflake Objects.

NEW QUESTION # 573
Which Snowflake object does not consume any storage costs?
- A. Materialized view
- B. Secure view
- C. Temporary table
- D. Transient table
Answer: C
Explanation:
Temporary tables do not consume any storage costs in Snowflake because they only exist for the duration of the session that created them and are automatically dropped when the session ends, thus incurring no long-term storage charges4.

NEW QUESTION # 574
When unloading data from Snowflake using the COPY INTO < location > command, what is a key consideration for handling NULL values?
- A. If a NULL value is detected during data loading, the process will stop and report an error.
- B. NULL values are automatically converted to empty strings.
- C. A string value should be specified to represent NULL values using the NULL_IF option.
- D. NULL values are automatically skipped during the unload process.
Answer: C
Explanation:
The correct answer is B. A string value should be specified to represent NULL values using the NULL_IF option .
When unloading data from Snowflake into files using the COPY INTO < location > command, Snowflake needs a textual representation for SQL NULL values in the unloaded files. This can be controlled by the NULL_IF file format option.
Why B is correct:
The NULL_IF option specifies one or more string values that represent SQL NULL values. During unloading, Snowflake uses this option to determine how NULL values should appear in the output files.
For example, a file format could specify:
NULL_IF = ( ' NULL ' )
This means SQL NULL values can be written using the string NULL in the unloaded file.
Why the other options are incorrect:
A). Snowflake does not always automatically convert NULL values to empty strings in all unload scenarios.
The representation depends on file format settings.
C). NULL values do not cause the unload process to stop with an error by default.
D). NULL values are not automatically skipped during unloading. They are included in the output using the configured representation.
Official Snowflake documentation reference:
Snowflake documentation for file format options explains that NULL_IF specifies the string used to represent SQL NULL values when loading or unloading data.

NEW QUESTION # 575
How often are encryption keys automatically rotated by Snowflake?
- A. 60 Days
- B. 30 Days
- C. 365 Days
- D. 90 Days
Answer: B
Explanation:
Snowflake automatically rotates encryption keys when they are more than 30 days old. Active keys are retired, and new keys are created. This process is part of Snowflake's comprehensive security measures to ensure data protection and is managed entirely by the Snowflake service without requiring user intervention.

NEW QUESTION # 576
Which typos of charts does Snowsight support? (Select TWO).
- A. Scorecards
- B. Area charts
- C. Radar charts
- D. Column charts
- E. Bar charts
Answer: B,E
Explanation:
Snowsight, Snowflake's user interface for executing and analyzing queries, supports various types of visualizations to help users understand their data better. Among the supported types, area charts and bar charts are two common options. Area charts are useful for representing quantities through the use of filled areas on the graph, often useful for showing volume changes over time. Bar charts, on the other hand, are versatile for comparing different groups or categories of data. Both chart types are integral to data analysis, enabling users to visualize trends, patterns, and differences in their data effectively.References: Snowflake Documentation on Snowsight Visualizations

NEW QUESTION # 578
Which stage type can be altered and dropped?
- A. User stage
- B. External stage
- C. Table stage
- D. Database stage
Answer: B
Explanation:
External stages can be altered and dropped in Snowflake. An external stage points to an external location, such as an S3 bucket, where data files are stored. Users can modify the stage's definition or drop it entirely if it's no longer needed. This is in contrast to table stages, which are tied to specific tables and cannot be altered or dropped independently.

NEW QUESTION # 579
Which statement about billing applies to Snowflake credits?
- A. Credits are used to pay for cloud data storage usage
- B. Credits are consumed based on the number of credits billed for each hour that a warehouse runs
- C. Credits are consumed based on the warehouse size and the time the warehouse is running
- D. Credits are billed per-minute with a 60-minute minimum
Answer: C
Explanation:
Snowflake credits are the unit of measure for the compute resources used in Snowflake. The number of credits consumed depends on the size of the virtual warehouse and the time it is running. Larger warehouses consume more credits per hour than smaller ones, and credits are billed for the time the warehouse is active, regardless of the actual usage within that time.
