When maintaining reports and dashboards, why is it essential to configure subscriptions and updates?
Correct Answer: B
Subscriptions and updates ensure timely information delivery, a crucial aspect of maintaining reports and dashboards.
Question 62
You're designing a data pipeline in Snowflake to process order data'. The raw order data, including customer information, is stored in a JSON format within a single 'RAW ORDERS table. Due to privacy regulations, you need to mask the customer's email addresses before loading the data into a 'CLEANED ORDERS' table, while maintaining referential integrity. Furthermore, you want to track the data lineage (which raw order resulted in which cleaned order) in a separate 'ORDER LINEAGE' table. Which of the following approaches achieves these requirements effectively and efficiently? (Select TWO)
Correct Answer: B,C
Option B: A stored procedure provides the most control over the masking process and lineage tracking, ensuring data is masked during the transfer. It allows you to perform all operations (masking, inserting into 'CLEANED ORDERS, and inserting into 'ORDER LINEAGE) within a single transaction. Option C: Snowpipe loading data to RAW_ORDERS, using streams to capture the data, and scheduling the tasks to read from the stream, while masking and adding lineage information provides automation and efficiency. Option A is incorrect, as it copies all data using a task into 'CLEANED_ORDERS and then masks the email on RAW_ORDERS after data is already in 'CLEANED_ORDERS'. Option D is incorrect as masking policy is on rather than Option E requires a view to mask email address and is not an effective approach to apply a masking policy. Also, its not the right procedure to load view into a table.
Question 63
You are working with a large dataset of website clickstream data'. You need to perform several data transformation steps, including filtering, aggregating, and joining with other tables. You want to ensure that your data cleaning and transformation process is idempotent, meaning that running the same transformation pipeline multiple times will produce the same result, even if the input data changes slightly. Which of the following strategies contribute to building an idempotent data transformation pipeline in Snowflake? (Select all that apply)
Correct Answer: A,B,D
Options A, B, and D are correct. Truncating the target table (A) before each run ensures a clean slate. Using 'MERGE statements (B) handles both updates and inserts, ensuring that the target table reflects the latest data state regardless of previous runs. Using clones (D) protects the original source data from unintended modifications during the transformation process, contributing to idempotency. Option C using just INSERT INTO is not idempotent as it will duplicate data on rerun. Option E, while useful for performance and cleanup, doesn't directly contribute to idempotency. The use of temporary tables alone does not guarantee idempotency if the operations performed on them are not idempotent. You might still see inconsistencies in data if the operations are not carefully designed. Truncating permanent table before adding data using MERGE is more reliable and ensures consistent result even on multiple runs.
Question 64
You've created a Snowflake dashboard for your company's sales team using a Bl tool. The dashboard displays real-time sales data pulled directly from Snowflake. The sales team wants to be automatically notified whenever a particular product's sales exceed a certain threshold in a given day. You need to implement a system to accomplish this. Which of the following methods offer a way to trigger notifications based on data changes in Snowflake AND integrate with an external notification system (e.g., Slack, Email)? Select all that apply:
Correct Answer: A,B
A and B offer native Snowflake capabilities for triggering actions based on data conditions and integrating with external systems. Alerts are designed for real-time monitoring and can call external functions to send notifications. Tasks can be scheduled to perform periodic checks and trigger notifications through stored procedures and external APIs. C: Streams and Pipes are primarily for continuous data loading and transformation, not direct notification triggering based on data conditions. It's an indirect method. D: BI tools are not the primary component for handling real time alerting based on exceeding specific values. E: Replication is for disaster recovery/high availability and doesn't address real- time notifications.
Question 65
In data presentations for business use analyses, what significance do identifying patterns and trends hold?
Correct Answer: C
Identifying patterns and trends aids in insightful analyses in business use scenarios.
