Snowflake SnowPro Advanced Architect Certification ARA-C01 Prüfungsfragen mit Lösungen (Q143-Q148):

143. Frage
How can an Architect enable optimal clustering to enhance performance for different access paths on a given table?

A. Create multiple materialized views with different cluster keys.
B. Create super projections that will automatically create clustering.
C. Create a clustering key that contains all columns used in the access paths.
D. Create multiple clustering keys for a table.

Antwort: A

Begründung:
According to the SnowPro Advanced: Architect documents and learning resources, the best way to enable optimal clustering to enhance performance for different access paths on a given table is to create multiple materialized views with different cluster keys. A materialized view is a pre-computed result set that is derived from a query on one or more base tables. A materialized view can be clustered by specifying a clustering key, which is a subset of columns or expressions that determines how the data in the materialized view is co-located in micro-partitions. By creating multiple materialized views with different cluster keys, an Architect can optimize the performance of queries that use different access paths on the same base table. For example, if a base table has columns A, B, C, and D, and there are queries that filter on A and B, or on C and D, or on A and C, the Architect can create three materialized views, each with a different cluster key: (A, B), (C, D), and (A, C). This way, each query can leverage the optimal clustering of the corresponding materialized view and achieve faster scan efficiency and better compression.

144. Frage
For authentication, snowflake Kafka connector relies on:

A. username/password
B. key pair authentication
C. Both key pair authentication and username/password

Antwort: B

145. Frage
A large table is accessed by multiple teams using point-lookup queries on different columns. Query performance is poor.
What can be done to ensure good performance for all teams?

A. Build multiple materialized views with cluster keys on each column.
B. Build materialized views and allow Snowflake to replace the base table.
C. Create clustering keys using a combination of all lookup columns.
D. Use the search optimization service on the underlying table.

Antwort: D

Begründung:
When multiple teams perform selective point-lookups on different columns of the same large table, traditional clustering is not effective because a table can have only one clustering key. Creating a composite clustering key across many columns often leads to poor clustering depth and limited pruning benefits.
The Search Optimization Service (SOS) is specifically designed for this scenario (Answer C). It enables fast point-lookups across multiple columns without requiring table reclustering. SOS maintains additional search access paths that accelerate highly selective predicates and is ideal when queries vary across many lookup columns.
Materialized views introduce additional storage, maintenance overhead, and operational complexity, and Snowflake does not automatically replace base tables with materialized views. This question tests an architect' s ability to choose the right optimization technique for multi-access-path workloads, a core SnowPro Architect competency.

146. Frage
A company has a table with that has corrupted data, named Data. The company wants to recover the data as it was 5 minutes ago using cloning and Time Travel.
What command will accomplish this?

A. CREATE TABLE Recover Data CLONE Data AT(TIME => -60*5);
B. CREATE CLONE Recover_Data FROM Data AT(OFFSET => -60*5);
C. CREATE CLONE TABLE Recover_Data FROM Data AT(OFFSET => -60*5);
D. CREATE TABLE Recover_Data CLONE Data AT(OFFSET => -60*5);

Antwort: D

Begründung:
Explanation
This is the correct command to create a clone of the table Data as it was 5 minutes ago using cloning and Time Travel. Cloning is a feature that allows creating a copy of a database, schema, table, or view without duplicating the data or metadata. Time Travel is a feature that enables accessing historical data (i.e. data that has been changed or deleted) at any point within a defined period. To create a clone of a table at a point in time in the past, the syntax is:
CREATE TABLE <clone_name> CLONE <source_table> AT (OFFSET => <offset_in_seconds>); The OFFSET parameter specifies the time difference in seconds from the present time. A negative value indicates a point in the past. For example, -60*5 means 5 minutes ago. Alternatively, the TIMESTAMP parameter can be used to specify an exact timestamp in the past. The clone will contain the data as it existed in the source table at the specified point in time12.

147. Frage
Which command below will load data from result_scan to a table?

A. CREATE OR REPLACE TABLE STORE_FROM_RESULT_SCAN AS select * from result_scan(last_query_id());
B. INSERT INTO STORE_FROM_RESULT_SCAN select * from result_scan(last_query_id());
C. CREATE OR REPLACE TABLE STORE_FROM_RESULT_SCAN AS select * from table(result_scan(last_query_id()));

Antwort: C
