Snowflake SnowPro Core Certification Exam COF-C02 Prüfungsfragen mit Lösungen (Q1086-Q1091):

1086. Frage
Which Snowflake function will interpret an input string as a JSON document, and produce a VARIANT value?

A. flatten
B. parse_json()
C. object_construct()
D. json_extract_path_text()

Antwort: D

1087. Frage
Which Snowflake objects track DML changes made to tables, like inserts, updates, and deletes?

A. Tasks
B. Pipes
C. Streams
D. Procedures

Antwort: C

Begründung:
In Snowflake, Streams are the objects that track Data Manipulation Language (DML) changes made to tables, such as inserts, updates, and deletes. Streams record these changes along with metadata about each change, enabling actions to be taken using the changed data. This process is known as change data capture (CDC)2.

1088. Frage
Which feature is integrated to support Multi-Factor Authentication (MFA) at Snowflake?

A. Authy
B. RSA SecurlD Access
C. Duo Security
D. One Login

Antwort: C

1089. Frage
If a table was dropped and the DATA_RETENTION_TIME_IN_DAYS was set to 0, how can the data from the table be recovered?

A. By running the CLONE ... BEFORE command
B. By creating a failover group
C. By creating a Snowflake Support ticket
D. By running the UNDROP TABLE command

Antwort: C

Begründung:
The correct answer is B. By creating a Snowflake Support ticket .
If DATA_RETENTION_TIME_IN_DAYS = 0, Time Travel retention is disabled for the table. This means the table cannot be recovered using normal Time Travel operations such as UNDROP TABLE or CLONE ...
BEFORE.
Why B is correct:
After Time Travel retention is unavailable, recovery may only be possible through Snowflake Fail-safe for permanent tables. Fail-safe is not directly accessible by users. Recovery from Fail-safe requires contacting Snowflake Support.
Important qualification:
This assumes the dropped table is a permanent table and the data is still within Fail-safe. Temporary and transient tables do not have Fail-safe, so they cannot be recovered this way.
Why the other options are incorrect:
A). A failover group is used for replication and disaster recovery across accounts or regions. It does not recover a dropped table with no Time Travel retention.
C). UNDROP TABLE relies on Time Travel retention. With retention set to 0, this is not available.
D). CLONE ... BEFORE also relies on Time Travel. It cannot recover data when no retention period exists.
Official Snowflake documentation reference:
Snowflake documentation explains that Time Travel enables users to restore dropped objects within the retention period. Fail-safe is a separate recovery mechanism for permanent tables and is only available through Snowflake Support.
Reference: Snowflake Documentation - Time Travel; Fail-safe; UNDROP TABLE; SnowPro Core Study Guide - Data Protection and Governance.

1090. Frage
How does Snowflake Copilot interact with customer data?

A. Copilot executes stored procedures in response to natural language prompts.
B. Copilot provides assistance when creating and interpreting queries.
C. Copilot rewrites table schemas based on inferred patterns in customer datasets.
D. Copilot analyzes customer data to optimize query performance.

Antwort: B

Begründung:
The correct answer is B. Copilot provides assistance when creating and interpreting queries .
Snowflake Copilot is an AI-assisted feature that helps users work with Snowflake more efficiently. It can assist with writing SQL, understanding queries, and interpreting query-related information.
Why B is correct:
Copilot is designed to help users create, refine, and understand SQL queries using natural language assistance.
Why the other options are incorrect:
A). Query optimization is primarily handled by Snowflake's optimizer and performance features, not Copilot.
C). Copilot does not automatically rewrite table schemas based on inferred data patterns.
D). Copilot is not primarily a feature for executing stored procedures from prompts.
Official Snowflake documentation reference:
Snowflake documentation describes Snowflake Copilot as an AI assistant for helping users generate, understand, and work with SQL and Snowflake data workflows.
