EMT Practice Test

1. Question Content...

---

Question1: An Administrator receives data from a Snowflake partner. The partner is sharing a dataset that contains multiple secure views. The Administrator would like to configure the data so that only certain roles can see certain secure views.
How can this be accomplished?

Question2: A data provider wants to share data from multiple databases with a data consumer account.
How can this be accomplished?

Question3: A user with the proper role issues the following commands when setting up and activating network policies:
CREATE OR REPLACE NETWORK POLICY foo_policy
ALLOWED_IP_LIST = ( '1.1.1.0/24', '2.2.2.0/24' , '3.3. 3. 0/24' )
BLOCKED IP LIST = ( '1.1.1.1')
COMMENT = 'Account level policy';
ALTER ACCOUNT SET NETWORK_POLICY=FOO_POLICY;
CREATE OR REPLACE NETWORK POLICY bar_policy
ALLOWED_IP_LIST = ('3.3.3.0/24')
BLOCKED IP LIST = ('3.3.3.10')
COMMENT = 'user level policy';
ALTER USER userl SET NETWORK_POLICY=BAR_POLICY;
Afterwards, user1 attempts to log in to Snowflake from IP address 3.3.3.10.
Will the login be successful?

Question4: What session parameter can be used to test the integrity of secure views based on the account that is accessing that view?

Question5: When does auto-suspend occur for a multi-cluster virtual warehouse?

Question6: A company has many users in the role ANALYST who routinely query Snowflake through a reporting tool. The Administrator has noticed that the ANALYST users keep two small clusters busy all of the time, and occasionally they need three or four clusters of that size.
Based on this scenario, how should the Administrator set up a virtual warehouse to MOST efficiently support this group of users?

Question7: A Snowflake Administrator is investigating why a query is not re-using the persisted result cache.
The Administrator found the two relevant queries from the SNOWFLAKE. ACCOUNT_USAGE. QUERY_HISTORY view:

Why is the second query re-scanning micro-partitions instead of using the first query's persisted result cache?

Question8: When adding secure views to a share in Snowflake, which function is needed to authorize users from another account to access rows in a base table?

Question9: The following commands were executed:
Grant usage on database PROD to role PROD_ANALYST;
Grant usage on database PROD to role PROD_SUPERVISOR;
Grant ALL PRIVILEGES on schema PROD. WORKING to role PROD_ANALYST;
Grant ALL PRIVILEGES on schema PROD. WORKING to role PROD_SUPERVISOR;
Grant role PROD ANALYST to user A;
Grant role PROD SUPERVISOR to user B;
What authority does each user have on the WORKING schema?

Question10: 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?

Question11: Which Snowflake objects can be managed using SCIM integration? (Select TWO).

Question12: 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?

Question13: Which actions are considered breaking changes to data that is shared with consumers in the Snowflake Marketplace? (Select TWO).

Question14: How should an Administrator configure a Snowflake account to use AWS PrivateLink?

Question15: A retailer uses a TRANSACTIONS table (100M rows, 1.2 TB) that has been clustered by the STORE_ID column (varchar(50)). The vast majority of analyses on this table are grouped by STORE_ID to look at store performance.
There are 1000 stores operated by the retailer but most sales come from only 20 stores. The Administrator notes that most queries are currently experiencing poor pruning, with large amounts of bytes processed by even simple queries.
Why is this occurring?

Question16: A virtual warehouse report_wh is configured with AUTO_RESUME=TRUE and AUTO_SUSPEND=300. A user has been granted the role accountant.
An application with the accountant role should use this warehouse to run financial reports, and should keep track of compute credits used by the warehouse.
What minimal privileges on the warehouse should be granted to the role to meet the requirements for the application? (Select TWO).

Question17: 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?

Question18: In which scenario will use of an external table simplify a data pipeline?

Question19: An Administrator wants to delegate the administration of a company's data exchange to users who do not have access to the ACCOUNTADMIN role.
How can this requirement be met?

Question20: Which statement allows this user to access this Snowflake account from a specific IP address (192.168.1.100) while blocking their access from anywhere else?

Question21: A requirement has been identified to allow members of a corporate Data Product team to bring in data sets from the Snowflake Marketplace. The members of this team use the role DP_TEAM.
What grant statements must the ACCOUNTADMIN execute in order for the DP TEAM role to import and work with data from the Marketplace?

Question22: What roles or security privileges will allow a consumer account to request and get data from the Data Exchange? (Select TWO).

Question23: A Snowflake account is configured with SCIM provisioning for user accounts and has bi-directional synchronization for user identities. An Administrator with access to SECURITYADMIN uses the Snowflake UI to create a user by issuing the following commands:
use role USERADMIN;
create or replace role DEVELOPER_ROLE;
create user PTORRES PASSWORD = 'hello world!' MUST_CHANGE_PASSWORD = FALSE default_role = DEVELOPER_ROLE; The new user named PTORRES successfully logs in, but sees a default role of PUBLIC in the web UI. When attempted, the following command fails:
use DEVELOPER_ROLE;
Why does this command fail?

Question24: An Administrator has a table named SALES_DATA which needs some edits, but the Administrator does not want to change the main table dat a. The Administrator decides to make a transient copy of this table and wants the transient table to have all the same permissions as the original table.
How can the Administrator create the transient table so it inherits the same permissions as the original table, and what considerations need to be made concerning the requirements? (Select TWO).

Question25: What Snowflake capabilities are commonly used in rollback scenarios? (Select TWO).

Question26: A team is provisioning new lower environments from the production database using cloning. All production objects and references reside in the database, and do not have external references.
What set of object references needs to be re-pointed before granting access for usage?

Question27: A Snowflake Administrator needs to persist all virtual warehouse configurations for auditing and backups. Given a table already exists with the following schema:
Table Name : VWH_META
Column 1 : SNAPSHOT_TIME TIMESTAMP_NTZ
Column 2 : CONFIG VARIANT
Which commands should be executed to persist the warehouse data at the time of execution in JSON format in the table VWH META?

Question28: An Administrator needs to implement an access control mechanism across an organization. The organization users access sensitive customer data that comes from different regions and needs to be accessible for Analysts who work in these regions. Some Analysts need very specific access control depending on their functional roles in the organization. Following Snowflake recommended practice, how should these requirements be met? (Select TWO).

Question29: What access control policy will be put into place when future grants are assigned to both database and schema objects?

Question30: A company enabled replication between accounts and is ready to replicate data across regions in the same cloud service provider.
The primary database object is : PROD_AWS_EAST. Location : AWS_EAST
The secondary database object is : PROD_AWS_WEST. Location : AWS_WEST
What command and account location is needed to refresh the data?

Question31: In general, the monthly billing for database replication is proportional to which variables? (Select TWO).

Question32: A company has implemented Snowflake replication between two Snowflake accounts, both of which are running on a Snowflake Enterprise edition. The replication is for the database APP_DB containing only one schema, APP_SCHEMA. The company's Time Travel retention policy is currently set for 30 days for both accounts. An Administrator has been asked to extend the Time Travel retention policy to 60 days on the secondary database only.
How can this requirement be met?

Question33: The following SQL command was executed:
Use role SECURITYADMIN;
Grant ownership
On future tables
In schema PROD. WORKING
To role PROD_WORKING_OWNER;
Grant role PROD_WORKING_OWNER to role SYSADMIN;
Use role ACCOUNTADMIN;
Create table PROD.WORKING.XYZ (value number) ;
Which role(s) can alter or drop table XYZ?
