NEW QUESTION # 733
How should Multi-Factor Authentication (MFA) be enabled for a user?
Answer: B
Explanation:
Users must self-enroll for MFA by logging into the web UI and scanning a QR code with an authenticator app. Administrators cannot do this on their behalf.
Reference:
Snowflake Docs: MFA Setup
NEW QUESTION # 734
Which Snowflake architectural layer is responsible for a query execution plan?
Answer: D
Explanation:
In Snowflake's architecture, the Cloud Services layer is responsible for generating the query execution plan.
This layer handles all the coordination, optimization, and management tasks, including query parsing, optimization, and compilation into an execution plan that can be processed by the Compute layer.
NEW QUESTION # 735
What are the default Time Travel and Fail-safe retention periods for transient tables?
Answer: D
Explanation:
Transient tables in Snowflake have a default Time Travel retention period of 1 day, which allows users to access historical data within the last 24 hours. However, transient tables do not have a Fail-safe period. Fail-safe is an additional layer of data protection that retains data beyond the Time Travel period for recovery purposes in case of extreme data loss.Since transient tables are designed for temporary or intermediate workloads with no requirement for long-term durability, they do not include a Fail-safe period by default1.

NEW QUESTION # 736
How would you determine the size of the virtual warehouse used for a task?
Answer: A
Explanation:
The size of the virtual warehouse for a task can be configured to handle concurrency automatically using a Multi-cluster warehouse (MCW). This is because tasks are designed to run their body on a schedule, and MCW allows for scaling compute resources to match the task's execution needs without manual intervention.

NEW QUESTION # 737
Which Snowflake tasks are managed in the cloud services layer? Select TWO.
Answer: C,E
Explanation:
The correct answers are C. Metadata management and E. Query parsing .
Snowflake's architecture has three main layers:
Cloud Services Layer
Query Processing Layer / Compute Layer
Database Storage Layer
The cloud services layer coordinates Snowflake activities and handles services such as authentication, infrastructure management, metadata management, query parsing and optimization, access control, and transaction management.
Why C is correct:
Metadata management is handled by the cloud services layer. This includes metadata about tables, micro- partitions, query optimization statistics, and access-related metadata.
Why E is correct:
Query parsing and optimization are handled by the cloud services layer before execution is assigned to compute resources.
Why the other options are incorrect:
A). Performance tuning is not usually described as a discrete cloud services task. Snowflake automatically optimizes many operations, but this option is too broad.
B). Query acceleration uses additional compute resources and is a performance feature, not a core task of the cloud services layer.
D). Query processing is performed by virtual warehouses in the compute layer, not by the cloud services layer.
Official Snowflake documentation reference:
Snowflake documentation explains that the cloud services layer manages authentication, infrastructure management, metadata, query parsing and optimization, access control, and transaction management.
