NEW QUESTION 80
A table contains five columns and it has millions of records. The cardinality distribution of the columns is shown below:

Column C4 and C5 are mostly used by SELECT queries in the GROUP BY and ORDER BY clauses.
Whereas columns C1, C2 and C3 are heavily used in filter and join conditions of SELECT queries.
The Architect must design a clustering key for this table to improve the query performance.
Based on Snowflake recommendations, how should the clustering key columns be ordered while defining the multi-column clustering key?

C5, C4, C2

C3, C4, C5

C1, C3, C2

C2, C1, C3

NEW QUESTION 81
What are characteristics of the use of transactions in Snowflake? (Select TWO).

Explicit transactions can contain DDL, DML, and query statements.

The autocommit setting can be changed inside a stored procedure.

A transaction can be started explicitly by executing a BEGIN WORK statement and ended explicitly by executing a COMMIT WORK statement.

A transaction can be started explicitly by executing a BEGIN TRANSACTION statement and ended explicitly by executing an END TRANSACTION statement.

Explicit transactions should contain only DML statements and query statements. All DDL statements implicitly commit active transactions.

NEW QUESTION 82
What is a characteristic of Role-Based Access Control (RBAC) as used in Snowflake?

Privileges can be granted at the database level and can be inherited by all underlying objects.

A user can use a “super-user” access along with securityadmin to bypass authorization checks and access all databases, schemas, and underlying objects.

A user can create managed access schemas to support future grants and ensure only schema owners can grant privileges to other roles.

A user can create managed access schemas to support current and future grants and ensure only object owners can grant privileges to other roles.

NEW QUESTION 83
What Snowflake features should be leveraged when modeling using Data Vault?

Snowflake’s support of multi-table inserts into the data model’s Data Vault tables

Data needs to be pre-partitioned to obtain a superior data access performance

Scaling up the virtual warehouses will support parallel processing of new source loads

Snowflake’s ability to hash keys so that hash key joins can run faster than integer joins

NEW QUESTION 84
Which steps are recommended best practices for prioritizing cluster keys in Snowflake? (Choose two.)

Choose columns that are frequently used in join predicates.

Choose lower cardinality columns to support clustering keys and cost effectiveness.

Choose TIMESTAMP columns with nanoseconds for the highest number of unique rows.

Choose cluster columns that are most actively used in selective filters.

Choose cluster columns that are actively used in the GROUP BY clauses.

NEW QUESTION 85
Which of the following are characteristics of how row access policies can be applied to external tables? (Choose three.)

An external table can be created with a row access policy, and the policy can be applied to the VALUE column.

A row access policy can be applied to the VALUE column of an existing external table.

A row access policy cannot be directly added to a virtual column of an external table.

External tables are supported as mapping tables in a row access policy.

While cloning a database, both the row access policy and the external table will be cloned.

A row access policy cannot be applied to a view created on top of an external table.

NEW QUESTION 86
A large manufacturing company runs a dozen individual Snowflake accounts across its business divisions. The company wants to increase the level of data sharing to support supply chain optimizations and increase its purchasing leverage with multiple vendors.
The company’s Snowflake Architects need to design a solution that would allow the business divisions to decide what to share, while minimizing the level of effort spent on configuration and management. Most of the company divisions use Snowflake accounts in the same cloud deployments with a few exceptions for European-based divisions.
According to Snowflake recommended best practice, how should these requirements be met?

Migrate the European accounts in the global region and manage shares in a connected graph architecture. Deploy a Data Exchange.

Deploy a Private Data Exchange in combination with data shares for the European accounts.

Deploy to the Snowflake Marketplace making sure that invoker_share() is used in all secure views.

Deploy a Private Data Exchange and use replication to allow European data shares in the Exchange.

According to Snowflake recommended best practice, the requirements of the large manufacturing company should be met by deploying a Private Data Exchange in combination with data shares for the European accounts. A Private Data Exchange is a feature of the Snowflake Data Cloud platform that enables secure and governed sharing of data between organizations. It allows Snowflake customers to create their own data hub and invite other parts of their organization or external partners to access and contribute data sets. A Private Data Exchange provides centralized management, granular access control, and data usage metrics for the data shared in the exchange1. A data share is a secure and direct way of sharing data between Snowflake accounts without having to copy or move the data. A data share allows the data provider to grant privileges on selected objects in their account to one or more data consumers in other accounts2. By using a Private Data Exchange in combination with data shares, the company can achieve the following benefits:
* The business divisions can decide what data to share and publish it to the Private Data Exchange, where it can be discovered and accessed by other members of the exchange. This reduces the effort and complexity of managing multiple data sharing relationships and configurations.
* The company can leverage the existing Snowflake accounts in the same cloud deployments to create the Private Data Exchange and invite the members to join. This minimizes the migration and setup costs and leverages the existing Snowflake features and security.
* The company can use data shares to share data with the European accounts that are in different regions or cloud platforms. This allows the company to comply with the regional and regulatory requirements for data sovereignty and privacy, while still enabling data collaboration across the organization.
* The company can use the Snowflake Data Cloud platform to perform data analysis and transformation on the shared data, as well as integrate with other data sources and applications. This enables the company to optimize its supply chain and increase its purchasing leverage with multiple vendors.
The other options are incorrect because they do not meet the requirements or follow the best practices. Option A is incorrect because migrating the European accounts to the global region may violate the data sovereignty and privacy regulations, and deploying a Data Exchange may not provide the level of control and management that the company needs. Option C is incorrect because deploying to the Snowflake Marketplace may expose the company’s data to unwanted consumers, and using invoker_share() in secure views may not provide the desired level of security and governance. Option D is incorrect because using replication to allow European data shares in the Exchange may incur additional costs and complexity, and may not be necessary if data shares can be used instead.

Use FURGE = FALSE in the copy into command.

Use on error = SKIP_FILE in the copy into command.

(Choose two.)

Enable a multi-clustered virtual warehouse in maximized mode during the workload duration.

Set the MAX_CONCURRENCY_LEVEL to a higher value than its default value of 8 at the virtual warehouse level.
