NO.324 How does Snowflake allow a data provider with an Azure account in central Canada to share data with a data consumer on AWS in Australia?

The data provider in Azure Central Canada can create a direct share to AWS Asia Pacific, if they are both in the same organization.

The data consumer and data provider can form a Data Exchange within the same organization to create a share from Azure Central Canada to AWS Asia Pacific.

The data provider uses the GET DATA workflow in the Snowflake Data Marketplace to create a share between Azure Central Canada and AWS Asia Pacific.

The data provider must replicate the database to a secondary account in AWS Asia Pacific within the same organization then create a share to the data consumer’s account.

Snowflake allows data providers to share data with consumers across different cloud platforms and regions through database replication. The data provider must replicate the database to a secondary account in the target region or cloud platform within the same organization, and then create a share to the data consumer’s account. This process ensures that the data is available in the consumer’s region and on their cloud platform, facilitating seamless data sharing.

NO.325 How can a Snowflake user post-process the result of SHOW FILE FORMATS?

Use the RESULT_SCAM function.

NO.326 The Information Schema and Account Usage Share provide storage information for which of the following objects? (Choose three.)

Users

Tables

Databases

Internal Stages

The Information Schema and Account Usage Share in Snowflake provide metadata and historical usage data for various objects within a Snowflake account. Specifically, they offer storage information for Tables, Databases, and Internal Stages. These schemas contain views and table functions that allow users to query object metadata and usage metrics, such as the amount of data stored and historical activity.
* Tables: The storage information includes data on the daily average amount of data in database tables.
* Databases: For databases, the storage usage is calculated based on all the data contained within the database, including tables and stages.
* Internal Stages: Internal stages are locations within Snowflake for temporarily storing data, and their storage usage is also tracked.
References: The information is verified according to the SnowPro Core Certification Study Guide and Snowflake documentation

NO.327 If a multi-cluster warehouse is using an economy scaling policy, how long will queries wait in the queue before another cluster is started?

1 minute

2 minutes

6 minutes

8 minutes

NO.328 How can the Query Profile be used to troubleshoot a problematic query?

It will indicate if a virtual warehouse memory is too small to run the query

It will indicate if a user lacks the privileges needed to run the query.

It will indicate if a virtual warehouse is in auto-scale mode

It will indicate if the user has enough Snowflake credits to run the query

The Query Profile in Snowflake provides detailed insights into the execution of a query. It helps in troubleshooting performance issues by showing the steps of the query execution and the resources consumed.
One of the key aspects it reveals is whether the virtual warehouse memory was sufficient for the query.
* Access Query Profile:Navigate to the Query History page and select the query you want to analyze.
* Examine Query Execution Steps:The Query Profile displays the different stages of the query execution, including the time taken and resources used at each step.
* Identify Memory Issues:Look for indicators of memory issues, such as spilling to disk or memory errors, which suggest that the virtual warehouse memory might be too small.

For how many days will the data be retained at the object level?

The settings shown in the image indicate that the data retention time in days is configured at two different levels: the account level and the object level. At the account level, the MIN_DATA_RETENTION_TIME_IN_DAYS is set to 5 days, and at the object level, the DATA_RETENTION_TIME_IN_DAYS is set to 2 days. Since the object level setting has a lower value, it takes precedence over the account level setting for the specific object. Therefore, the data will be retained for 2 days at the object level.References: Snowflake Documentation on Data Retention Policies
