質問 # 546
The following JSON is stored in a VARIANT column called src of the CAR_SALES table:
A user needs to extract the dealership information from the JSON.
How can this be accomplished?
正解：C
質問 # 547
Which feature is designed to reduce security risks associated with an individual user ' s password authentication?
正解：D
解説：
The correct answer is A. Multi-Factor Authentication, or MFA .
Multi-Factor Authentication reduces the risk of relying only on a username and password. Even if a password is compromised, MFA requires an additional verification factor before the user can access Snowflake.
Why A is correct:
MFA strengthens password-based authentication by requiring an extra factor, such as a push approval, passcode, or other verification method. Snowflake's native MFA is powered by Duo Security.
Why the other options are incorrect:
B). Standard authentication usually refers to username and password authentication, which is exactly the risk the question wants to reduce.
C). Snowflake OAuth is an authorization/authentication integration method, but MFA is the direct feature designed to reduce password-only risk.
D). External OAuth can centralize authentication through an external identity provider, but the best Snowflake security feature for reducing password authentication risk is MFA.
Official Snowflake documentation reference:
Snowflake documentation describes MFA as an additional layer of security for user login and explains that Snowflake MFA is powered by Duo Security.

質問 # 548
Which JSON paths are considered to be equivalent in Snowflake? (Select TWO).
正解：B、E
解説：
* In Snowflake, JSON path equivalence occurs when different syntax representations refer to the same nested element in a JSON object.
* Correct Examples:
* A. src['customer']['EMAIL']: Explicit bracket notation is case-insensitive in Snowflake and works for nested JSON elements.
* D. src:customer.email: Dot notation is also case-insensitive and is equivalent to bracket notation in Snowflake.
Why Other Options Are Incorrect:
* B. src['CUSTOMER']['Email']: The case-sensitive mismatch causes this to be non-equivalent.
* C. SRC:Customer.Email: Case-sensitive mismatches with the key name.
* E. SRC:customer.email: Incorrect due to unnecessary uppercase in SRC.

質問 # 549
How can an administrator check for updates (for example, SCIM API requests) sent to Snowflake by the identity provider?
正解：C
解説：
To monitor updates, such as SCIM API requests sent to Snowflake by the identity provider, an administrator can use theREST EVENT HISTORYfeature. This feature allows administrators to query historical data about REST API calls made to Snowflake, including those related to user and role management through SCIM (System for Cross-domain Identity Management).
TheREST EVENT HISTORYtable function returns information about REST API calls made over a specified period. It is particularly useful for auditing and monitoring purposes, especially when integrating Snowflake with third-party identity providers that use SCIM for automated user provisioning and deprovisioning.
An example query to check for SCIM API requests might look like this:
SELECT*FROMTABLE(information_schema.rest_event_history(date_range_start=>dateadd('hours',-1,current_
='SCIM';
This query returns details on SCIM API requests made in the last hour, including the request type, the identity provider's details, and the outcome of each request.

質問 # 550
Which function unloads data from a relational table to JSON?
正解：C
解説：
To unload data from a relational table to JSON format, you can use the TO_CHAR function. This function converts a number to a character string, which can then be serialized into JSON format. While there isn't a direct function specifically named for unloading to JSON, converting the necessary fields to a string representation is a common step in preparing data for JSON serialization.
