Snowflake SnowPro Advanced Administrator Sample Questions (Q12-Q17):

NEW QUESTION # 12
A Snowflake user runs a complex SQL query on a dedicated virtual warehouse that reads a large amount of data from micro-partitions. The same user wants to run another query that uses the same data set.
Which action would provide optimal performance for the second SQL query?

A. Prevent the virtual warehouse from suspending between the running of the first and second queries.
B. Use the RESULT_SCAN function to post-process the output of the first query.
C. Increase the STATEMENT_TIMEOUT_IN_SECONDS parameter in the session.
D. Assign additional clusters to the virtual warehouse.

Answer: B

Explanation:
According to the Using Persisted Query Results documentation, the RESULT_SCAN function allows you to query the result set of a previous command as if it were a table. This can improve the performance of the second query by avoiding reading the same data from micro-partitions again. The other actions do not provide optimal performance for the second query because:
* Assigning additional clusters to the virtual warehouse does not affect the data access speed, but only the query execution speed. It also increases the cost of the warehouse.
* Increasing the STATEMENT_TIMEOUT_IN_SECONDS parameter in the session does not improve the performance of the query, but only allows it to run longer before timing out. It also increases the risk of resource contention and deadlock.
* Preventing the virtual warehouse from suspending between the running of the first and second queries does not guarantee that the data will be cached in memory, as Snowflake uses a least recently used (LRU) cache eviction policy. It also increases the cost of the warehouse.

NEW QUESTION # 13
In which scenario will use of an external table simplify a data pipeline?

A. When accessing a Snowflake table from a relational database
B. When accessing a Snowflake table from an external database within the same region
C. When accessing a Snowflake table that references data files located in cloud storage
D. When continuously writing data from a Snowflake table to external storage

Answer: C

Explanation:
Explanation
According to the Introduction to External Tables documentation, an external table is a Snowflake feature that allows you to query data stored in an external stage as if the data were inside a table in Snowflake. The external stage is not part of Snowflake, so Snowflake does not store or manage the stage. This simplifies the data pipeline by eliminating the need to load the data into Snowflake before querying it. External tables can access data stored in any format that the COPY INTO <table> command supports, such as CSV, JSON, AVRO, ORC, or PARQUET. The other scenarios do not involve external tables, but rather require data loading, unloading, or federation.

NEW QUESTION # 14
A user has enrolled in Multi-factor Authentication (MFA) for connecting to Snowflake. The user informs the Snowflake Administrator that they lost their mobile phone the previous evening.
Which step should the Administrator take to allow the user to log in to the system, without revoking their MFA enrollment?

A. Alter the user and set MINS TO BYPASS MFA to a value that will disable MFA long enough for the user to log in.
B. Instruct the user to append the normal URL with /?mode=mfa_bypass&code= to log on.
C. Instruct the user to connect to Snowflake using SnowSQL, which does not support MFA authentication.
D. Alter the user and set DISABLE_MFA to true, which will suspend the MFA requirement for 24 hours.

Answer: A

Explanation:
The MINS_TO_BYPASS_MFA property allows the account administrator to temporarily disable MFA for a user who has lost their phone or changed their phone number1. The user can log in without MFA for the specified number of minutes, and then re-enroll in MFA using their new phone1. This does not revoke their MFA enrollment, unlike the DISABLE_MFA property, which cancels their enrollment and requires them to re-enroll from scratch1. The other options are not valid ways to bypass MFA, as SnowSQL does support MFA authentication2, and there is no such URL parameter as /?mode=mfa_bypass&code= for Snowflake3

NEW QUESTION # 15
An Administrator has a user who needs to be able to suspend and resume a task based on the current virtual warehouse load, but this user should not be able to modify the task or start a new run.
What privileges should be granted to the user to meet these requirements? (Select TWO).

A. OWNERSHIP on the database and schema containing the task
B. EXECUTE TASK on the task
C. OWNERSHIP on the task
D. USAGE on the database and schema containing the task
E. OPERATE on the task

Answer: D,E

Explanation:
Explanation
The user needs the OPERATE privilege on the task to suspend and resume it, and the USAGE privilege on the database and schema containing the task to access it1. The EXECUTE TASK privilege is not required for suspending and resuming a task, only for triggering a new run1. The OWNERSHIP privilege on the task or the database and schema would allow the user to modify or drop the task, which is not desired.

NEW QUESTION # 16
A Snowflake organization MYORG consists of two Snowflake accounts:

The ACCOUNT1 has a database PROD_DB and the ORGADMIN role enabled.
Management wants to have the PROD_DB database replicated to ACCOUNT2.
Are there any necessary configuration steps in ACCOUNT1 before the database replication can be configured and initiated in ACCOUNT2?

A. USE ROLE ORGADMIN;
SELECT SYSTEMSGLOBAL ACCOUNT SET_PARAMETER ( 'MYORG. ACCOUNT1',
'ENABLE_ACCOUNT_DATABASE_REPLICATION', 'TRUE');
USE ROLE ACCOUNTADMIN;
ALTER DATABASE PROD_DB ENABLE REPLICATION TO ACCOUNTS MYORG. ACCOUNT2
IGNORE EDITION CHECK;
B. USE ROLE ORGADMIN;
SELECT SYSTEMSGLOBAL_ACCOUNT_SET_PARAMETER ('MYORG. ACCOUNT1',
'ENABLE_ACCOUNT_DATABASE_REPLICATION', 'TRUE');
SELECT SYSTEMSGLOBAL_ACCOUNT_SET_PARAMETER ('MYORG. ACCOUNT2',
'ENABLE_ACCOUNT_DATABASE_REPLICATION', 'TRUE');
USE ROLE ACCOUNTADMIN;
ALTER DATABASE PROD DB ENABLE REPLICATION TO ACCOUNTS MYORG. ACCOUNT2;
C. It is not possible to replicate a database from an Enterprise edition Snowflake account to a Standard edition Snowflake account.
D. No configuration steps are necessary in ACCOUNT1. Replicating databases across accounts within the same Snowflake organization is enabled by default.

Answer: A

Explanation:
Explanation
According to the Snowflake documentation1, database replication across accounts within the same organization requires the following steps:
*Link the accounts in the organization using the ORGADMIN role.
*Enable account database replication for both the source and target accounts using the SYSTEM$GLOBAL_ACCOUNT_SET_PARAMETER function.
*Promote a local database to serve as the primary database and enable replication to the target accounts using the ALTER DATABASE ... ENABLE REPLICATION TO ACCOUNTS command.
*Create a secondary database in the target account using the CREATE DATABASE ... FROM SHARE command.
*Refresh the secondary database periodically using the ALTER DATABASE ... REFRESH command.
Option A is incorrect because it does not include the step of creating a secondary database in the target account. Option C is incorrect because replicating databases across accounts within the same organization is not enabled by default, but requires enabling account database replication for both the source and target accounts. Option D is incorrect because it is possible to replicate a database from an Enterprise edition Snowflake account to a Standard edition Snowflake account, as long as the IGNORE EDITION CHECK option is used in the ALTER DATABASE ... ENABLE REPLICATION TO ACCOUNTS command2.
Option B is correct because it includes all the necessary configuration steps in ACCOUNT1, except for creating a secondary database in ACCOUNT2, which can be done after the replication is enabled.
