By default, which role has access to the SYSTEM$GLOBAL_ACCOUNT_SET_PARAMETER function?
- A. SECURITYADMIN
- B. ACCOUNTADMIN
- C. SYSADMIN

Answer: C
NEW QUESTION # 438
A Snowflake account has activated federated authentication.
What will occur when a user with a password that was defined by Snowflake attempts to log in to Snowflake?
- A. After entering the username and password, the user will be redirected to an Identity Provider (IdP) login page.
- B. The user will encounter an error, and will not be able to log in.
- C. The user will be unable to enter a password.
- D. The user will be able to log into Snowflake successfully.
Answer: C
Explanation:
When federated authentication is activated in Snowflake, users authenticate via an external identity provider (IdP) rather than using Snowflake-managed credentials. Therefore, a user with a password defined by Snowflake will be unable to enter a password and must use their IdP credentials to log in.

NEW QUESTION # 441
What action should be taken if a large number of concurrent queries are queued in a virtual warehouse?
- A. Disable auto-suspend on the warehouse.
- B. Scale-out with a multi-cluster warehouse.
- C. Scale-up by resizing the warehouse.
- D. Enable auto-resume on the warehouse.
Answer: B
Explanation:
When a large number of concurrent queries are queued in a virtual warehouse in Snowflake, the most effective action is to scale out using a multi-cluster warehouse. Here's why:
* Understanding the Problem:
* When many queries are queued, it indicates that the computational resources of the warehouse are insufficient to handle the demand.
* Each virtual warehouse in Snowflake provides a fixed amount of compute resources. A single cluster in the warehouse can only process a finite number of concurrent queries efficiently.
* Scale-Out with Multi-Cluster Warehouse:
* Snowflake's multi-cluster warehouse feature allows a warehouse to dynamically add or remove clusters based on the current workload.
* With scale-out, additional clusters are automatically spun up when the query load increases. This helps distribute the workload and reduces queuing without impacting ongoing query performance.
* Once the load decreases, the additional clusters are automatically suspended, optimizing costs.
* Why Not Other Options?:
* A. Scale-up by resizing the warehouse: While scaling up (choosing a larger size, e.g., from X- Small to Medium) increases compute power, it may not efficiently resolve queuing when many concurrent queries need to be processed. It's better suited for improving the performance of individual queries rather than handling more queries simultaneously.
* C. Disable auto-suspend on the warehouse: This ensures the warehouse remains active but does not address the queuing issue. Keeping a warehouse perpetually active can lead to unnecessary costs.
* D. Enable auto-resume on the warehouse: This ensures the warehouse activates when needed but does not directly impact query concurrency.
* Best Practices for Scaling with Multi-Cluster Warehouses:
* Configure the minimum and maximum cluster settings to allow Snowflake to handle varying workloads efficiently.
* Use auto-scaling policies like "economy" or "standard" to control cluster behavior based on cost or performance requirements.
* Steps to Implement Multi-Cluster Warehouse:
* Navigate to the Snowflake console.
* Go to the "Warehouses" tab and select the target warehouse.
* Edit the warehouse settings to set:
* Minimum Clusters: The minimum number of active clusters.
* Maximum Clusters: The upper limit of clusters that Snowflake can scale out to.
* Auto-Resume and Auto-Suspend: Ensure these are enabled for cost efficiency.

NEW QUESTION # 442
How many network policies can be assigned to an account or specific user at a time?
- A. Three
- B. Unlimited
- C. One
- D. Two
Answer: C
Explanation:
According to my knowledge, a security administrator can create multiple network policies, but only one network policy can be active for an account or specific user at any given time. This ensures that there is a clear and consistent policy being applied without conflicts. Reference: Based on my internal knowledge as of 2021.
NEW QUESTION # 443
The is the minimum Fail-safe retention time period for transient tables?
- A. 0 days
- B. 7 days
- C. 12 hours
- D. 1 day
Answer: A
Explanation:
Transient tables in Snowflake have a minimum Fail-safe retention time period of 0 days. This means that once the Time Travel retention period ends, there is no additional Fail-safe period for transient tables
NEW QUESTION # 444
Which command can be performed on a Snowflake secure view?
- A. SELECT
- B. DELETE
- C. INSERT
- D. UPDATE
Answer: A
Explanation:
* A secure view in Snowflake is designed to enforce stricter access control and prevent unauthorized access to the underlying data.
* Only SELECT statements can be performed on a secure view, as they are read-only objects.
Why Other Options Are Incorrect:
* B. INSERT / C. UPDATE / D. DELETE: Secure views do not allow DML (Data Manipulation Language) operations.
References:
* Secure Views Documentation
NEW QUESTION # 445
Use of which file function allows a user to share unstructured data from an internal stage with an external reporting tool that does not have access to Snowflake">
- A. BUILD_SCOPED_FILE_URL
- B. GET_PRESIGNED_URL
- C. GET_STAGE_LOCATION
- D. BUILD_STAGE_FILE_URL
Answer: B
Explanation:
The GET_PRESIGNED_URL function in Snowflake generates a pre-signed URL for a file in an internal stage. This URL can be shared with external tools or users who do not have direct access to Snowflake, allowing them to download the file.
* Generate Pre-Signed URL:
SELECT GET_PRESIGNED_URL(@my_stage/file.txt);
* Share the URL: The generated URL can be shared with external users or applications, enabling them to access the file directly.

* Snowflake Documentation: GET_PRESIGNED_URL

NEW QUESTION # 446
If 3 size Small virtual warehouse is made up of two servers, how many servers make up a Large warehouse?
- A. 0
- B. 1
- C. 2
- D. 3
Answer: C
Explanation:
In Snowflake, each size increase in virtual warehouses doubles the number of servers. Therefore, if a size Small virtual warehouse is made up of two servers, a Large warehouse, which is two sizes larger, would be made up of eight servers (2 servers for Small, 4 for Medium, and 8 for Large)2.
Size specifies the amount of compute resources available per cluster in a warehouse. Snowflake supports the following warehouse sizes:

NEW QUESTION # 450
Which type of Snowflake virtual warehouse provides 16 times the memory for each node and is recommended for larger workloads like Machine Learning (ML) training?
- A. A size 6XL warehouse
- B. A multi-cluster warehouse
- C. A standard warehouse
- D. A Snowpark-optimized warehouse
Answer: D
Explanation:
The Snowpark-optimized warehouse is designed with significantly higher memory per node, making it ideal for machine learning (ML) training and other memory-intensive workloads. Snowpark-optimized warehouses provide the necessary computational power and memory for complex, large-scale data processing tasks.
Standard and multi-cluster warehouses do not offer the same memory advantage, while the 6XL warehouse is large but not specifically optimized for memory-intensive operations.
