NEW QUESTION # 177
Which statement accurately describes Snowflake's architecture?
Answer: C
Explanation:
Snowflake's architecture is unique in that it combines elements of both traditional shared-disk and shared-nothing database architectures. This hybrid approach allows Snowflake to offer the scalability and performance benefits of a shared-nothing architecture (with compute and storage separated) while maintaining the simplicity and flexibility of a shared-disk architecture in managing data across all nodes in the system. This results in an architecture that provides on-demand scalability, both vertically and horizontally, without sacrificing performance or data cohesion.

NEW QUESTION # 178
Will data cached in a warehouse be lost when the warehouse is resized?
Answer: C
Explanation:
When a Snowflake virtual warehouse is resized, the data cached in the warehouse is not lost. This is because the cache is maintained independently of the warehouse size. Resizing a warehouse, whether scaling up or down, does not affect the cached data, ensuring that query performance is not impacted by such changes.

NEW QUESTION # 179
Which step will increase security related to user access to a Snowflake account?
Answer: B
Explanation:
The correct answer is B. Restrict access to Snowflake to known networks using a network policy .
A network policy improves account access security by allowing or blocking access based on IP address ranges. This helps ensure that users can connect to Snowflake only from approved networks.
Why B is correct:
Network policies can restrict inbound access to Snowflake by defining allowed and blocked IP address ranges. This is a direct security control for user access to a Snowflake account.
Example concept:
CREATE NETWORK POLICY corp_network_policy
ALLOWED_IP_LIST = ( ' 203.0.113.0/24 ' );
ALTER ACCOUNT SET NETWORK_POLICY = corp_network_policy;
Why the other options are incorrect:
A). A UDF is not the correct tool for managing account access security. Monitoring security parameters may provide visibility, but it does not directly restrict access.
C). A short session timeout can reduce risk from idle sessions, but making it "very short" can harm usability and is not as direct as network restrictions.
D). Every user already has access to the PUBLIC role by default. Setting restrictive permissions on PUBLIC is good practice, but it is not as direct as restricting access through a network policy.
Official Snowflake documentation reference:
Snowflake documentation describes network policies as security controls that restrict access to Snowflake based on allowed and blocked IP address lists.
Reference: Snowflake Documentation - Network policies; Snowflake Documentation - Network policy best practices; SnowPro Core Study Guide - Security and Access Control.

NEW QUESTION # 180
Which type of workload is recommended for Snowpark-optimized virtual warehouses?
Answer: B
Explanation:
Snowpark-optimized virtual warehouses in Snowflake are designed to efficiently handle workloads with large memory requirements. Snowpark is a developer framework that allows users to write code in languages like Scala, Java, and Python to process data in Snowflake. Given the nature of these programming languages and the types of data processing tasks they are typically used for, having a virtual warehouse that can efficiently manage large memory-intensive operations is crucial.
Understanding Snowpark-Optimized Virtual Warehouses:
Snowpark allows developers to build complex data pipelines and applications within Snowflake using familiar programming languages.
These virtual warehouses are optimized to handle the execution of Snowpark workloads, which often involve large datasets and memory-intensive operations.
Large Memory Requirements:
Workloads with large memory requirements include data transformations, machine learning model training, and advanced analytics.
These operations often need to process significant amounts of data in memory to perform efficiently.
Snowpark-optimized virtual warehouses are configured to provide the necessary memory resources to support these tasks, ensuring optimal performance and scalability.
Other Considerations:
While Snowpark can handle other types of workloads, its optimization for large memory tasks makes it particularly suitable for scenarios where data processing needs to be done in-memory.
Snowflake's ability to scale compute resources dynamically also plays a role in efficiently managing large memory workloads, ensuring that performance is maintained even as data volumes grow.
