최신 SnowPro Advanced ADA-C02 무료샘플문제 (Q15-Q20):

질문 # 15
What is a characteristic of Snowflake's transaction locking and concurrency modeling?

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

정답：B

설명：
Snowflake uses multi-version concurrency control (MVCC), which allows queries and DML statements to operate without blocking each other. This architecture eliminates the possibility of deadlocks because transactions work on snapshots of data rather than locking rows or tables in ways that could cause contention.

질문 # 16
What access control policy will be put into place when future grants are assigned to both database and schema objects?

A. An access policy combining both the database object and the schema object will be used, with the most restrictive policy taking precedence.
B. Database, privileges will take precedence over schema privileges.
C. An access policy combining both the database object and the schema object will be used, with the most permissive policy taking precedence.
D. Schema privileges will take precedence over database privileges.

정답：D

설명：
When future grants are set at both the database and schema levels, schema-level future grants take precedence over database-level grants for objects created within that schema.

질문 # 17
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. Clone the data and insert it into a company-owned share and apply the desired RBAC on the new tables.
B. Create views over the incoming shared database and apply the desired RBAC onto these views.
C. Individually grant imported privileges onto the schema in the share.
D. Apply RBAC directly onto the partner's shared secure views.

정답：B

설명：
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.

질문 # 18
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? (Choose two.)

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

정답：A,D

설명：
To suspend and resume a task, the user needs the OPERATE privilege on the task. Additionally, USAGE on the database and schema containing the task is required to access it. Granting these together allows control of task state without giving modification or ownership rights.

질문 # 19
What Snowflake capabilities are commonly used in rollback scenarios? (Choose two.)

A. Contact Snowflake Support to retrieve Fail-safe data.
B. CREATE TABLE prd_table_bkp as SELECT * from table(result_scan('problematic_query_id'));
C. SELECT SYSTEM$CANCEL_QUERY('problematic_query_id');
D. CREATE TABLE prd_table_bkp CLONE prd_table BEFORE (STATEMENT => 'problematic_query_id');
E. ALTER TABLE prd_table SWAP WITH prd_table_bkp;

정답：D,E

설명：
Creating a clone of a table at a point in time before a problematic statement uses Snowflake Time Travel to restore the table’s previous state without copying data. This allows recovery of the table as it existed before the issue occurred.
Swapping tables enables a fast rollback by exchanging the original production table with the restored backup table. This operation is metadata-only and allows immediate restoration of the previous version of the data with minimal downtime.
