NEW QUESTION # 12
A Snowflake Architect is designing a multi-tenant application strategy for an organization in the Snowflake Data Cloud and is considering using an Account Per Tenant strategy.
Which requirements will be addressed with this approach? (Choose two.)

• A. Compute costs must be optimized.
• B. There needs to be fewer objects per tenant.
• C. Storage costs must be optimized.
• D. Tenant data shape may be unique per tenant.
• E. Security and Role-Based Access Control (RBAC) policies must be simple to configure.

Answer: C,D

Explanation:
Explanation
* An Account Per Tenant strategy means creating a separate Snowflake account for each tenant (customer or business unit) of the multi-tenant application.
* This approach has some advantages and disadvantages compared to other strategies, such as Database Per Tenant or Schema Per Tenant.
* One advantage is that each tenant can have a unique data shape, meaning they can define their own tables, views, and other objects without affecting other tenants. This allows for more flexibility and customization for each tenant. Therefore, option D is correct.
* Another advantage is that storage costs can be optimized, because each tenant can use their own storage credits and manage their own data retention policies. This also reduces the risk of data spillover or cross-tenant access. Therefore, option E is correct.
* However, this approach also has some drawbacks, such as:
* It requires more administrative overhead and complexity to manage multiple accounts and their resources.
* It may not optimize compute costs, because each tenant has to provision their own warehouses and pay for their own compute credits. This may result in underutilization or overprovisioning of compute resources. Therefore, option C is incorrect.
* It may not simplify security and RBAC policies, because each account has to define its own roles, users, and privileges. This may increase the risk of human errors or inconsistencies in security configurations. Therefore, option B is incorrect.
* It may not reduce the number of objects per tenant, because each tenant still has to create their own databases, schemas, and other objects within their account. This mayaffect the performance and scalability of the application. Therefore, option A is incorrect.

NEW QUESTION # 19
When using the Snowflake Connector for Kafka, what data formats are supported for the messages? (Choose two.)

• A. Parquet
• B. JSON
• C. XML
• D. CSV
• E. Avro

Answer: B,E

Explanation:
Explanation
The data formats that are supported for the messages when using the Snowflake Connector for Kafka are Avro and JSON. These are the two formats that the connector can parse and convert into Snowflake table rows. The connector supports both schemaless and schematized JSON, as well as Avro with or without a schema registry1. The other options are incorrect because they are not supported data formats for the messages. CSV, XML, and Parquet are not formats that the connector can parse and convert into Snowflake table rows. If the messages are in these formats, the connector will load them as VARIANT data type and store them as raw strings in the table2.

NEW QUESTION # 22
A Snowflake Architect is designing an application and tenancy strategy for an organization where strong legal isolation rules as well as multi-tenancy are requirements.

• A. Create a multi-tenant table strategy if row level security is not viable for isolating tenants.
• B. Create an object for each tenant strategy if row level security is viable for isolating tenants.
• C. Create accounts for each tenant in the Snowflake organization.
• D. Create an object for each tenant strategy if row level security is not viable for isolating tenants.

Answer: B

NEW QUESTION # 23
Refreshing a secondary database is not allowed in the following circumstances

NEW QUESTION # 24
A company has several sites in different regions from which the company wants to ingest data.
Which of the following will enable this type of data ingestion?

• A. The company should provision a reader account to each site and ingest the data through the reader accounts.
• B. The company must replicate data between Snowflake accounts.
• C. The company should use a storage integration for the external stage.
• D. The company must have a Snowflake account in each cloud region to be able to ingest data to that account.

Answer: C

Explanation:
Explanation
This is the correct answer because it allows the company to ingest data from different regions using a storage integration for the external stage. A storage integration is a feature that enables secure and easy access to files in external cloud storage from Snowflake. A storage integration can be used to create an external stage, which is a named location that references the files in the external storage. An external stage can be used to load data into Snowflake tables using the COPY INTO command, or to unload data from Snowflake tables using the COPY INTO LOCATION command. A storage integration can support multiple regions and cloud platforms, as long as the external storage service is compatible with Snowflake12.

NEW QUESTION # 26
What Snowflake features should be leveraged when modeling using Data Vault?

• A. Scaling up the virtual warehouses will support parallel processing of new source loads
• B. Snowflake's ability to hash keys so that hash key joins can run faster than integer joins
• C. Data needs to be pre-partitioned to obtain a superior data access performance
• D. Snowflake's support of multi-table inserts into the data model's Data Vault tables

Answer: A,D

Explanation:
Explanation
These two features are relevant for modeling using Data Vault on Snowflake. Data Vault is a data modeling approach that organizes data into hubs, links, and satellites. Data Vault is designed to enable high scalability, flexibility, and performance for data integration and analytics. Snowflake is a cloud data platform that supports various data modeling techniques, including Data Vault. Snowflake provides some features that can enhance the Data Vault modeling, such as:
* Snowflake's support of multi-table inserts into the data model's Data Vault tables. Multi-table inserts (MTI) are a feature that allows inserting data from a single query into multiple tables in a single DML statement. MTI can improve the performance and efficiency of loading datainto Data Vault tables, especially for real-time or near-real-time data integration. MTI can also reduce the complexity and maintenance of the loading code, as well as the data duplication and latency12.
* Scaling up the virtual warehouses will support parallel processing of new source loads. Virtual warehouses are a feature that allows provisioning compute resources on demand for data processing.
Virtual warehouses can be scaled up or down by changing the size of the warehouse, which determines the number of servers in the warehouse. Scaling up the virtual warehouses can improve the performance and concurrency of processing new source loads into Data Vault tables, especially for large or complex data sets. Scaling up the virtual warehouses can also leverage the parallelism and distribution of Snowflake's architecture, which can optimize the data loading and querying34.

NEW QUESTION # 27

• A. TRUE
• B. FALSE

Answer: A

NEW QUESTION # 28
A company has a table with that has corrupted data, named Data. The company wants to recover the data as it was 5 minutes ago using cloning and Time Travel.
What command will accomplish this?

• A. CREATE CLONE TABLE Recover_Data FROM Data AT(OFFSET => -60*5);
• B. CREATE TABLE Recover Data CLONE Data AT(TIME => -60*5);
• C. CREATE TABLE Recover_Data CLONE Data AT(OFFSET => -60*5);
• D. CREATE CLONE Recover_Data FROM Data AT(OFFSET => -60*5);

Answer: C

Explanation:
Explanation
This is the correct command to create a clone of the table Data as it was 5 minutes ago using cloning and Time Travel. Cloning is a feature that allows creating a copy of a database, schema, table, or view without duplicating the data or metadata. Time Travel is a feature that enables accessing historical data (i.e. data that has been changed or deleted) at any point within a defined period. To create a clone of a table at a point in time in the past, the syntax is:
CREATE TABLE <clone_name> CLONE <source_table> AT (OFFSET => <offset_in_seconds>); The OFFSET parameter specifies the time difference in seconds from the present time. A negative value indicates a point in the past. For example, -60*5 means 5 minutes ago. Alternatively, the TIMESTAMP parameter can be used to specify an exact timestamp in the past. The clone will contain the data as it existed in the source table at the specified point in time12.
