最新的 SnowPro Advanced: Administrator ADA-C01 免費考試真題 (Q63-Q68):

問題 #63
A large international company with many operating regions requires data to be shared bi-directionally among all offices (head office to regional offices and regional offices among themselves). This company is a Snowflake account holder with European operations deployed in Microsoft Azure (single region) while North American regional offices are using AWS (single region) as their deployment cloud. This setup is required to comply with Personal Identifiable Information (PII) regulations in some of the European countries. The corporate head office is in Europe.
How can this data be shared bi-directionally, while MINIMIZING costs?

A. Use bi-directional data sharing among offices in the same region and replication among offices across the continents.
B. Move all the Snowflake accounts to a single region, and implement data sharing.
C. Use data replication everywhere to reduce costs associated with same-region sharing.
D. Use the PUT command to move files to an Amazon S3 bucket and Azure Blobs, and use an external file management application to move files within the corporate VPC.

答案：A

解題說明：
Explanation
According to the Snowflake documentation1, data sharing is a feature that allows sharing selected objects in a database in one account with other accounts in the same organization, without copying or transferring any data. Data sharing is supported across regions and across cloud platforms, but it requires enabling account database replication for both the source and target accounts2. Data replication is a feature that allows replicating objects from a source account to one or more target accounts in the same organization, providing read-only access for the replicated objects. Data replication is also supported across regions and across cloud platforms, but it incurs additional storage costs for the replicated data2. Therefore, the best way to share data bi-directionally among all offices, while minimizing costs, is to use data sharing among offices in the same region, which does not require replication or additional storage, and use replication among offices across the continents, which provides near real-time access to the shared data. Option A is incorrect because using data replication everywhere would increase the costs associated with additional storage and compute resources for the replicated data. Option B is incorrect because using the PUT command to move files to an Amazon S3 bucket and Azure Blobs, and using an external file management application to move files within the corporate VPC, would not leverage the benefits of Snowflake's data sharing and replication features, and would also incur additional costs and complexity for data transfer and synchronization. Option C is incorrect because moving all the Snowflake accounts to a single region would violate the PII regulations in some of the European countries, and would also incur additional costs and complexity for data migration and consolidation.

問題 #64
What are benefits of using Snowflake organizations? (Select TWO).

A. Administrators can simplify data movement across all accounts within the organization.
B. Administrators have the ability to create accounts in any available cloud provider or region.
C. Administrators can monitor and understand usage across all accounts in the organization.
D. User administration is simplified across all accounts within the organization.
E. Administrators can change Snowflake account editions on-demand based on need.

答案：B,C

解題說明：
According to the Snowflake documentation1, organizations are a feature that allows linking the accounts owned by a business entity, simplifying account management and billing, replication and failover, data sharing, and other account administration tasks. Some of the benefits of using organizations are:
* Administrators can monitor and understand usage across all accounts in the organization using the ORGANIZATION_USAGE schema, which provides historical usage data for all accounts in the organization via views in a shared database named SNOWFLAKE2. This can help to optimize costs and performance across the organization.
* Administrators have the ability to create accounts in any available cloud provider or region using the CREATE ACCOUNT command, which allows specifying the cloud platform and region for the new account3. This can help to meet the business needs and compliance requirements of the organization.
Option A is incorrect because administrators cannot change Snowflake account editions on-demand based on need, but rather have to contact Snowflake Support to request an edition change4. Option C is incorrect because administrators cannot simplify data movement across all accounts within the organization, but rather have to enable account database replication for both the source and target accounts, and use the ALTER DATABASE ... ENABLE REPLICATION TO ACCOUNTS command to promote a local database to serve as the primary database and enable replication to the target accounts5. Option D is incorrect because user administration is not simplified across all accounts within the organization, but rather requires creating and managing users, roles, and privileges for each account separately, unless using a federated authentication method such as SSO or SCIM.

問題 #65
An Administrator needs to create a sample of the table LINEITEM. The sample should not be repeatable and the sampling function should take the data by blocks of rows.
What select command will generate a sample of 20% of the table?

A. select * from LINEITEM sample system (20);
B. select * from LINEITEM sample bernoulli (20);
C. select * from LINEITEM tablesample system (20) seed (1);
D. select * from LINEITEM tablesample block (20 rows);

答案：A

解題說明：
This command will generate a sample of 20% of the table by using the SYSTEM (or BLOCK) sampling method, which selects each block of rows with a probability of 20/100. This method is suitable for taking data by blocks of rows, as the question requires. According to the Snowflake documentation, "SYSTEM (or BLOCK): Includes each block of rows with a probability of p/100. Similar to flipping a weighted coin for each block of rows. This method does not support fixed-size sampling." The other options are either incorrect or do not meet the requirements of the question. Option A uses the BERNOULLI (or ROW) sampling method, which selects each row with a probability of 20/100, but does not take data by blocks of rows. Option C uses the BLOCK sampling method, but specifies a fixed number of rows (20) instead of a percentage (20%). Option D uses the SYSTEM sampling method, but specifies a seed value (1), which makes the sampling repeatable, contrary to the question.

問題 #66
What is a characteristic of Snowflake's transaction locking and concurrency modeling?

A. Transaction locking in Snowflake is enforced exclusively at the row and table levels.
B. Queries executed within a given transaction see that transaction's uncommitted changes.
C. If two queries are concurrently executed against the same table, one of the two queries will be blocked until the other query completes.
D. A deadlock cannot occur in Snowflake, since concurrently executed queries and DML statements do not block one another.

答案：D

解題說明：
Explanation
According to the Snowflake documentation1, Snowflake uses a multi-version concurrency control (MVCC) model, which means that each transaction operates on a consistent snapshot of the database at a point in time.
This allows queries and DML statements to run concurrently without blocking each other, as they do not modify the same data. Therefore, a deadlock, which occurs when concurrent transactions are waiting on resources that are locked by each other, cannot happen in Snowflake. Option B is incorrect because queries and DML statements do not block each other in Snowflake, unless they are explicitly started transactions and multiple statements in each transaction2. Option C is incorrect because transaction locking in Snowflake is enforced at the partition level, not the row or table level3. Option D is incorrect because queries executed within a given transaction do not see that transaction's uncommitted changes, but only the committed changes that occurred before the transaction started1.

問題 #67
What are characteristics of data replication in Snowflake? (Select THREE).

A. The ALTER DATABASE ... ENABLE REPLICATION TO ACCOUNTS command must be issued from the primary account.
B. Databases created from shares can be replicated.
C. Users must be granted REPLICATIONADMIN privileges in order to enable replication.
D. Users can have unlimited primary databases and they can be replicated to an unlimited number of accounts if all accounts are within the same organization.
E. To start replication run the ALTER DATABASE ... REFRESH command on the account where the secondary database resides.
F. Replication can only occur within the same cloud provider.

答案：A,B,D

解題說明：
Explanation
*Option A is correct because the ALTER DATABASE ... ENABLE REPLICATION TO ACCOUNTS command must be issued from the primary account that owns the database to be replicated1.
*Option B is incorrect because users must be granted REPLICATIONGRANTER privileges in order to enable replication1.
*Option C is incorrect because to start replication, the ALTER DATABASE ... REFRESH command must be run on the primary database, not the secondary database1.
*Option D is incorrect because replication can occur across different cloud providers, as well as across regions2.
*Option E is correct because databases created from shares can be replicated, as long as the share is active and the database is not dropped or altered1.
*Option F is correct because users can have unlimited primary databases and they can be replicated to an unlimited number of accounts if all accounts are within the same organization1.
