Snowflake SnowPro Advanced Administrator ADA-C02 ADA-C02 Prüfungsfragen mit Lösungen (Q25-Q30):

25. Frage
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?

A. Create views over the incoming shared database and apply the desired RBAC onto these views.
B. Clone the data and insert it into a company-owned share and apply the desired RBAC on the new tables.
C. Individually grant imported privileges onto the schema in the share.
D. Apply RBAC directly onto the partner's shared secure views.

Antwort: A

Begründung:
Permissions cannot be applied directly to objects in a shared database. To enforce role-based access, the Administrator must create views over the shared secure views in a local database and then apply RBAC privileges to those new views. This allows controlling which roles can see which data.

26. Frage
What roles can be used to create network policies within Snowflake accounts? (Choose three.)

A. SYSADMIN
B. Any role with the global permission of CREATE NETWORK POLICY
C. ORGADMIN
D. Any role that owns the database where the network policy is created
E. ACCOUNTADMIN
F. SECURITYADMIN

Antwort: C,E,F

Begründung:
SECURITYADMIN, ACCOUNTADMIN, and ORGADMIN roles can create network policies in Snowflake accounts. These roles have the necessary privileges to manage account-level security policies.

27. Frage
What is required for stages, without credentials, to limit data exfiltration after a storage Integration and associated stages are created?

A. ALTER ACCOUNT my_account SET
REQUIRE_STORAGE_INTEGRATION_FOR_STAGE_CREATION = true;
ALTER ACCOUNT my_account SET
REQUIRE_STORAGE_INTEGRATION_FOR_STAGE_OPERATION = true;
ALTER ACCOUNT my_account SET
PREVENT_UNLOAD_TO_INLINE_URL = true;
B. ALTER ACCOUNT my_account SET
REQUIRE_STORAGE_INTEGRATION_FOR_STAGE_CREATION = false;
ALTER ACCOUNT my_account SET
REQUIRE_STORAGE_INTEGRATION_FOR_STAGE_OPERATION = false;
ALTER ACCOUNT my_account SET
PREVENT_UNLOAD_TO_INLINE_URL = true;
C. ALTER ACCOUNT my_account SET
REQUIRE_STORAGE_INTEGRATION_FOR_STAGE_CREATION = false;
ALTER ACCOUNT my_account SET
REQUIRE_STORAGE_INTEGRATION_FOR_STAGE_OPERATION = false;
ALTER ACCOUNT my_account SET
PREVENT_UNLOAD_TO_INLINE_URL = false;
D. ALTER ACCOUNT my_account SET
REQUIRE_STORAGE_INTEGRATION_FOR_STAGE_CREATION = true;
ALTER ACCOUNT my_account SET
REQUIRE_STORAGE_INTEGRATION_FOR_STAGE_OPERATION = true;
ALTER ACCOUNT my_account SET
PREVENT_UNLOAD_TO_INLINE_URL = false;

Antwort: A

Begründung:
To prevent data exfiltration, Snowflake requires storage integrations for both stage creation and stage operations, ensuring that unmanaged external locations cannot be used. Additionally, setting PREVENT_UNLOAD_TO_INLINE_URL = true blocks unloading directly to unsecured inline URLs. This configuration enforces secure stage usage tied to storage integrations.

28. Frage
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?

A. The table is not big enough to take advantage of the clustering key.
B. The STORE_ID should be numeric.
C. The cardinality of the stores to transaction count ratio is too low to use the STORE_ID as a clustering key.
D. Sales across stores are not uniformly distributed.

Antwort: D

Begründung:
Clustering is effective when data distribution across the clustering key is relatively uniform. In this case, most transactions are concentrated in only 20 of the 1000 stores, leading to skewed data distribution. This imbalance causes poor pruning, since large portions of micro-partitions still need to be scanned, even for queries targeting specific stores.

29. Frage
What roles or security privileges will allow a consumer account to request and get data from the Data Exchange? (Choose two.)

A. IMPORT PRIVILEGES and SHARED DATABASE
B. SYSADMIN
C. IMPORT SHARE and CREATE DATABASE
D. SECURITYADMIN
E. ACCOUNTADMIN

Antwort: C,E

Begründung:
ACCOUNTADMIN role is required to access and manage Data Exchange listings and shares.
The IMPORT SHARE and CREATE DATABASE privileges are required to create databases from shared data.
