A company's security audit requires generating a report listing all Snowflake logins (e.g.. date and user) within the last 90 days. Which of the following statements will return the required information?
SELECT LAST_SUCCESS_LOGIN, LOGIN_NAME
FROM ACCOUNT_USAGE.USERS;
SELECT EVENT_TIMESTAMP, USER_NAME
FROM table(information_schema.login_history_by_user())
SELECT EVENT_TIMESTAMP, USER_NAME
FROM ACCOUNT_USAGE.ACCESS_HISTORY;
SELECT EVENT_TIMESTAMP, USER_NAME
FROM ACCOUNT_USAGE.LOGIN_HISTORY;
A user has an application that writes a new Tile to a cloud storage location every 5 minutes.
What would be the MOST efficient way to get the files into Snowflake?
Create a task that runs a copy into operation from an external stage every 5 minutes
Create a task that puts the files in an internal stage and automate the data loading wizard
Create a task that runs a GET operation to intermittently check for new files
Set up cloud provider notifications on the Tile location and use Snowpipe with auto-ingest

A user is loading JSON documents composed of a huge array containing multiple records into Snowflake. The user enables the strip__outer_array file format option
What does the STRIP_OUTER_ARRAY file format do?
It removes the last element of the outer array.
It removes the outer array structure and loads the records into separate table rows,
It removes the trailing spaces in the last element of the outer array and loads the records into separate table columns
It removes the NULL elements from the JSON object eliminating invalid data and enables the ability to load the records
Data Size Limitations
The VARIANT data type imposes a 16 MB size limit on individual rows.
For some semi-structured data formats (e.g. JSON), data sets are frequently a simple concatenation of multiple documents. The JSON output from some software is composed of a single huge array containing multiple records. There is no need to separate the documents with line breaks or commas, though both are supported.
If the data exceeds 16 MB, enable the STRIP_OUTER_ARRAY file format option for the COPY INTO
