  1. Snowpark
  2. Snowpipe
  3. ML Functions
  4. AI_EXTRACT

Answer(s): C

Which tools, services, or features should be used to write code when using the Snowpark API? (Choose two.)

  1. Snowpark Container Services
  2. Snowpark for Scala
  3. Snowpark for Python
  4. Streamlit in Snowflake
  5. SQL Scripting

The data retention time for a schema is set for 5 days, and the data retention time for the database that contains the schema is set for 10 days.

Based on these settings, what would the default data retention time be for a permanent table created in the schema?

  1. 0 days
  2. 1 day
  3. 5 days
  4. 10 days

Answer(s): C

Explanation:

A table inherits the data retention period from its schema if explicitly set, so the schema-level setting of 5 days overrides the database-level setting.

answer to this question "what administrative safeguards should be implemented to protect the collected data while in use by manasa and her product management team? " it should be (c) for the following reasons: this administrative safeguard involves controlling access to collected data by ensuring that only individuals who need the data for their job responsibilities have access to it. this helps minimize the risk of unauthorized access and potential misuse of sensitive information. while other options such as (a) documenting data flows and (b) conducting a privacy impact assessment (pia) are important steps in data protection, implementing a "need to know" access policy directly addresses the issue of protecting data while in use by limiting access to those who require it for legitimate purposes. (d) is not directly related to safeguarding data during use; it focuses on data transfers and location.

q. 289 - the correct answer should be b not d, since the question asks for the most secure way to provide access to a s3 bucket (a single one), and by principle of the least privilege you should not be giving access to all buckets.
