To determine the output of the final statement, a Data Analyst must perform a step-by-step trace of the code execution, following standard order of operations (inner-to-outer) and procedural logic within the Snowflake Scripting environment.
Step 1: Evaluating the innermost function, func2(10)
The definition for func2 takes a number p and returns p + 10.
Step 2: Evaluating the next function, func1(20)
The definition for func1 takes a number v and returns v + 10.
Input: 20 (the result from Step 1)
Calculation: $20 + 10 = 30$
Result: 30
Step 3: Evaluating the procedure call, proc1(30)
The procedure proc1 takes an input variable named result. It then executes a conditional IF statement:
Conditional Check: IF (result >= 30)
Since the input is 30, the condition evaluates to True.
Action: The procedure executes RETURN result - 10.
Calculation: $30 - 10 = 20$
Summary of Logic:
The nested calls flow as follows: call proc1(30) $\rightarrow$ proc1 evaluates $30 \ge 30$ $\rightarrow$ proc1 returns $30 - 10$, which is 20. If the initial input had been lower, such that the final result passed to the procedure was less than 30, it would have followed the ELSE branch and returned the original value. This question evaluates the analyst's ability to interpret modular code and procedural control flow, which are key components of the Data Transformation and Data Modeling domain in the SnowPro Advanced: Data Analyst exam.
