NO.50 Running EXPLAIN on a query does not require a running warehouse

 TRUE

 FALSE

NO.51 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.
Which approach will meet these requirements if Role-Based Access Policies (RBAC) is a viable option for isolating tenants?

 Create accounts for each tenant in the Snowflake organization.

 Create an object for each tenant strategy if row level security is viable for isolating tenants.

 Create an object for each tenant strategy if row level security is not viable for isolating tenants.

 Create a multi-tenant table strategy if row level security is not viable for isolating tenants.

NO.52 A Data Engineer is designing a near real-time ingestion pipeline for a retail company to ingest event logs into Snowflake to derive insights. A Snowflake Architect is asked to define security best practices to configure access control privileges for the data load for auto-ingest to Snowpipe.
What are the MINIMUM object privileges required for the Snowpipe user to execute Snowpipe?

 OWNERSHIP on the named pipe, USAGE on the named stage, target database, and schema, and INSERT and SELECT on the target table

 OWNERSHIP on the named pipe, USAGE and READ on the named stage, USAGE on the target database and schema, and INSERT end SELECT on the target table

 CREATE on the named pipe, USAGE and READ on the named stage, USAGE on the target database and schema, and INSERT end SELECT on the target table

 USAGE on the named pipe, named stage, target database, and schema, and INSERT and SELECT on the target table

NO.53 Which columns can be included in an external table schema? (Select THREE).

 VALUE

 METADATASROW_ID

NO.54 Which of the below operations are allowed on an inbound share data?

 MERGE

 CREATE/DROP/ALTER TABLE

 ALTER SCHEMA

 SELECT WITH JOIN

 SELECT WITH GROUP BY

 INSERT INTO

NO.55 An Architect needs to allow a user to create a database from an inbound share.
To meet this requirement, the user’s role must have which privileges? (Choose two.)

 IMPORT SHARE;

 IMPORT PRIVILEGES;

 CREATE DATABASE;

 CREATE SHARE;

 IMPORT DATABASE;

According to the Snowflake documentation, to create a database from an inbound share, the user’s role must have the following privileges:
The CREATE DATABASE privilege on the current account. This privilege allows the user to create a new database in the account1.
The IMPORT DATABASE privilege on the share. This privilege allows the user to import a database from the share into the account2. The other privileges listed are not relevant for this requirement. The IMPORT SHARE privilege is used to import a share into the account, not a database3. The IMPORT PRIVILEGES privilege is used to import the privileges granted on the shared objects, not the objects themselves2. The CREATE SHARE privilege is used to create a share to provide data to other accounts, not to consume data from other accounts4.
Reference:

NO.56 How do Snowflake databases that are created from shares differ from standard databases that are not created from shares? (Choose three.)

 Shared databases are read-only.

 Shared databases must be refreshed in order for new data to be visible.

 Shared databases cannot be cloned.

 Shared databases are not supported by Time Travel.

 Shared databases will have the PUBLIC or INFORMATION_SCHEMA schemas without explicitly granting these schemas to the share.

 Shared databases can also be created as transient databases.

Explanation
According to the SnowPro Advanced: Architect documents and learning resources, the ways that Snowflake databases that are created from shares differ from standard databases that are not created from shares are:
* Shared databases are read-only. This means that the data consumers who access the shared databases cannot modify or delete the data or the objects in the databases. The data providers who share the databases have full control over the data and the objects, and can grant or revoke privileges on them1.
* Shared databases cannot be cloned. This means that the data consumers who access the shared databases cannot create a copy of the databases or the objects in the databases. The data providers who share the databases can clone the databases or the objects, but the clones are not automatically shared2.
* Shared databases are not supported by Time Travel. This means that the data consumers who access the shared databases cannot use the AS OF clause to query historical data or restore deleted data. The data providers who share the databases can use Time Travel on the databases or the objects, but the historical data is not visible to the data consumers3.
The other options are incorrect because they are not ways that Snowflake databases that are created from shares differ from standard databases that are not created from shares. Option B is incorrectbecause shared databases do not need to be refreshed in order for new data to be visible. The data consumers who access the shared databases can see the latest data as soon as the data providers update the data1. Option E is incorrect because shared databases will not have the PUBLIC or INFORMATION_SCHEMA schemas without explicitly granting these schemas to the share. The data consumers who access the shared databases can only see the objects that the data providers grant to the share, and the PUBLIC and INFORMATION_SCHEMA schemas are not granted by default4. Option F is incorrect because shared databases cannot be created as transient databases. Transient databases are databases that do not support Time Travel or Fail-safe, and can be dropped without affecting the retention period of the data. Shared databases are always created as permanent databases, regardless of the type of the source database5.

NO.57 How is the change of local time due to daylight savings time handled in Snowflake tasks? (Choose two.)

 A task scheduled in a UTC-based schedule will have no issues with the time changes.

 Task schedules can be designed to follow specified or local time zones to accommodate the time changes.

 A task will move to a suspended state during the daylight savings time change.

 A frequent task execution schedule like minutes may not cause a problem, but will affect the task history.

 A task schedule will follow only the specified time and will fail to handle lost or duplicated hours.

Explanation
According to the Snowflake documentation1 and the web search results2, these two statements are true about how the change of local time due to daylight savings time is handled in Snowflake tasks. A task is a feature that allows scheduling and executing SQL statements or stored procedures in Snowflake. A task can be scheduled using a cron expression that specifies the frequency and time zone of the task execution.
* A task scheduled in a UTC-based schedule will have no issues with the time changes. UTC is a universal time standard that does not observe daylight savings time. Therefore, a task that uses UTC as the time zone will run at the same time throughout the year, regardless of the local time changes1.
* Task schedules can be designed to follow specified or local time zones to accommodate the time changes. Snowflake supports using any valid IANA time zone identifier in the cron expression for a task. This allows the task to run according to the local time of the specified time zone, which may include daylight savings time adjustments. For example, a task that uses Europe/London as the time zone will run one hour earlier or later when the local time switches between GMT and BST12.

* Snowflake Documentation: Scheduling Tasks
* Snowflake Community: Do the timezones used in scheduling tasks in Snowflake adhere to daylight savings?

NO.58 Validation mode can take the below options

 RETURN_<n>_ROWS

 RETURN_ERRORS

 RETURN_ALL_ERRORS

 RETURN_SEVERE_EERORS_ONLY

NO.59 A company wants to deploy its Snowflake accounts inside its corporate network with no visibility on the internet. The company is using a VPN infrastructure and Virtual Desktop Infrastructure (VDI) for its Snowflake users. The company also wants to re-use the login credentials set up for the VDI to eliminate redundancy when managing logins.
What Snowflake functionality should be used to meet these requirements? (Choose two.)

 Set up replication to allow users to connect from outside the company VPN.

 Provision a unique company Tri-Secret Secure key.

 Use private connectivity from a cloud provider.

 Set up SSO for federated authentication.

 Use a proxy Snowflake account outside the VPN, enabling client redirect for user logins.

NO.60 A company’s daily Snowflake workload consists of a huge number of concurrent queries triggered between
9pm and 11pm. At the individual level, these queries are smaller statements that get completed within a short time period.
What configuration can the company’s Architect implement to enhance the performance of this workload?
(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.

 Increase the size of the virtual warehouse to size X-Large.

 Reduce the amount of data that is being processed through this workload.

 Set the connection timeout to a higher value than its default.

Explanation
These two configuration options can enhance the performance of the workload that consists of a huge number of concurrent queries that are smaller and faster.
* Enabling a multi-clustered virtual warehouse in maximized mode allows the warehouse to scale out automatically by adding more clusters as soon as the current cluster is fully loaded, regardless of the number of queries in the queue. This can improve the concurrency and throughput of the workload by minimizing or preventing queuing. The maximized mode is suitable for workloads that require high performance and low latency, and are less sensitive to credit consumption1.
* Setting the MAX_CONCURRENCY_LEVEL to a higher value than its default value of 8 at the virtual warehouse level allows the warehouse to run more queries concurrently on each cluster. This can improve the utilization and efficiency of the warehouse resources, especially for smaller and faster queries that do not require a lot of processing power. The MAX_CONCURRENCY_LEVEL parameter can be set when creating or modifying a warehouse, and it can be changed at any time2.

* Snowflake Documentation: MAX_CONCURRENCY_LEVEL

NO.61 A company is using a Snowflake account in Azure. The account has SAML SSO set up using ADFS as a SCIM identity provider. To validate Private Link connectivity, an Architect performed the following steps:
* Confirmed Private Link URLs are working by logging in with a username/password account
* Verified DNS resolution by running nslookups against Private Link URLs
* Validated connectivity using SnowCD
* Disabled public access using a network policy set to use the company’s IP address range However, the following error message is received when using SSO to log into the company account:
IP XX.XXX.XX.XX is not allowed to access snowflake. Contact your local security administrator.
What steps should the Architect take to resolve this error and ensure that the account is accessed using only Private Link? (Choose two.)

 Alter the Azure security integration to use the Private Link URLs.

 Add the IP address in the error message to the allowed list in the network policy.

 Generate a new SCIM access token using system$generate_scim_access_token and save it to Azure AD.

 Update the configuration of the Azure AD SSO to use the Private Link URLs.

 Open a case with Snowflake Support to authorize the Private Link URLs’ access to the account.

Explanation
The error message indicates that the IP address in the error message is not allowed to access Snowflake because it is not in the allowed list of the network policy. The network policy is a feature that allows restricting access to Snowflake based on IP addresses or ranges. To resolve this error, the Architect should take the following steps:
* Add the IP address in the error message to the allowed list in the network policy. This will allow the IP address to access Snowflake using the Private Link URLs. Alternatively, the Architect can disable the network policy if it is not required for security reasons.
* Update the configuration of the Azure AD SSO to use the Private Link URLs. This will ensure that the SSO authentication process uses the Private Link URLs instead of the public URLs. The configuration can be updated by following the steps in the Azure documentation1.
These two steps should resolve the error and ensure that the account is accessed using only Private Link. The other options are not necessary or relevant for this scenario. Altering the Azure security integration to use the Private Link URLs is not required because the security integration is used for SCIM provisioning, not for SSO authentication. Generating a new SCIM access token using system$generate_scim_access_token and saving it to Azure AD is not required because the SCIM access token is used for SCIM provisioning, not for SSO authentication. Opening a case with Snowflake Support to authorize the Private Link URLs’ access to the account is not required because the authorization can be done by the account administrator using the SYSTEM$AUTHORIZE_PRIVATELINK function2.

NO.62 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?

 The company must have a Snowflake account in each cloud region to be able to ingest data to that account.

 The company must replicate data between Snowflake accounts.

 The company should provision a reader account to each site and ingest the data through the reader accounts.

 The company should use a storage integration for the external stage.

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.

NO.63 You have turned on auto clustering in your table.
How will you monitor how much credit is getting burnt for the auto clustering in the past week for a specific table?

 Run the below query select * from table(information_schema.automatic_clustering_history(date_range_start=>dateadd(d, -7, current_date), date_range_end=>current_date, table_name=>’mydb.myschema.mytable’));

 SHOW AUTO CLUSTERING INFO

NO.64 There are two databases in an account, named fin_db and hr_db which contain payroll and employee data, respectively. Accountants and Analysts in the company require different permissions on the objects in these databases to perform their jobs. Accountants need read-write access to fin_db but only require read-only access to hr_db because the database is maintained by human resources personnel.
An Architect needs to create a read-only role for certain employees working in the human resources department.
Which permission sets must be granted to this role?

 USAGE on database hr_db, USAGE on all schemas in database hr_db, SELECT on all tables in database hr_db

 USAGE on database hr_db, SELECT on all schemas in database hr_db, SELECT on all tables in database hr_db

 MODIFY on database hr_db, USAGE on all schemas in database hr_db, USAGE on all tables in database hr_db

 USAGE on database hr_db, USAGE on all schemas in database hr_db, REFERENCES on all tables in database hr_db
