Salesforce Certified Platform Developer I Sample Questions (Q142-Q147):

NEW QUESTION # 142
A developer created a trigger on the Account object. While testing the trigger, the developer sees the error message 'Maximum trigger depth exceeded'.
What could be the possible causes?

A. The trigger is getting executed multiple times.
B. The developer does not have the correct user permission.
C. The trigger does not have sufficient code coverage.
D. The trigger is too long and should be refactored into a helper class.

Answer: A

Explanation:
The error message 'Maximum trigger depth exceeded' occurs when a trigger invokes itself recursively more than the allowed limit.
Option C: The trigger is getting executed multiple times.
Correct Answer.
This error indicates that the trigger is recursively calling itself.
This can happen if the trigger performs an update or insert operation that causes the same trigger to fire again, leading to an infinite loop.
Salesforce enforces a limit on the recursion depth to prevent stack overflows.
User permissions do not cause the 'Maximum trigger depth exceeded' error.
Option B: The trigger is too long and should be refactored into a helper class.
*Incorrect, but possible code improvement.
While refactoring code into helper classes is a good practice, it does not directly address the recursion issue causing the error.
Option D: The trigger does not have sufficient code coverage.
Incorrect.
Code coverage issues affect deployment but do not cause runtime errors like 'Maximum trigger depth exceeded'.
Conclusion:
The error is caused because the trigger is getting executed multiple times due to recursion, leading to exceeding the maximum trigger depth.

Incorrect Options:
Option A: The developer does not have the correct user permission.
Incorrect.

NEW QUESTION # 145
Refer to the following Apex code:

What is the value of x when it is written to the debug log?

A. 0
B. 1
C. 2
D. 3

Answer: B

NEW QUESTION # 146
Refer to the following Apex code:
apex
Copy
Integer x = 0;
do {
x++;
} while (x < 1);
System.debug(x);
What is the value of x when it is written to the debug log?

A. 0
B. 1
C. 2
D. 3

Answer: B

Explanation:
Comprehensive and Detailed Explanation From Exact Extract:
To determine the value of x when it is written to the debug log, we need to analyze the Apex code step by step, focusing on the behavior of the do-while loop and how it affects the variable x. Let's break down the code execution systematically, referencing Salesforce's official Apex Developer Guide.
Code Analysis:
The given Apex code is:
apex
Copy
Integer x = 0;
do {
x++;
} while (x < 1);
System.debug(x);
Step 1: Initial State
* Integer x = 0;: The variable x is initialized to 0. The Apex Developer Guide states: "An Integer in Apex is a 32-bit number that does not include decimal points, initialized to 0 by default if no value is provided" (Salesforce Apex Developer Guide, Primitive Data Types). Here, x is explicitly set to 0.
Step 2: Understanding the do-while Loop
* A do-while loop in Apex executes the loop body at least once before evaluating the condition. The Apex Developer Guide explains: "The do-while loop executes the block of code in the do statement first, then checks the condition in the while statement. If the condition is true, the loop continues; otherwise, it exits" (Salesforce Apex Developer Guide, Loops).
* The loop body is:
apex
Copy
x++;
This increments x by 1 using the post-increment operator (++). The Apex Developer Guide confirms: "The ++ operator increments the value of the variable by 1" (Salesforce Apex Developer Guide, Expressions and Operators).
* The condition is:
apex
Copy
while (x < 1);
The loop continues as long as x < 1 evaluates to true.
Step 3: Loop Execution
* First Iteration:
* Initial value: x = 0.
* Execute the loop body: x++ # x becomes 1 (0 + 1).
* Evaluate the condition: x < 1 # 1 < 1 # false (since 1 is not less than 1).
* Since the condition is false, the loop exits after the first iteration.
* After the Loop:
* The value of x is now 1.
* The do-while loop guarantees at least one execution, which is why x is incremented once before the condition check fails.
Step 4: Debug Statement
* System.debug(x);: This writes the value of x to the debug log. At this point, x = 1. The Apex Developer Guide states: "System.debug outputs the value of the specified variable to the debug log for troubleshooting" (Salesforce Apex Developer Guide, System Class).
* Therefore, the debug log will show 1.
Evaluating the Options:
* A. 0: Incorrect. The initial value of x is 0, but the do-while loop increments x to 1 in the first iteration, and the loop exits because the condition x < 1 is false. The debug log shows the final value of x, which is 1.
* B. 2: Incorrect. The loop only runs once because after the first iteration, x becomes 1, and the condition x < 1 fails (1 < 1 is false). There is no second iteration to increment x to 2.
* C. 1: Correct. As calculated, the loop executes once, incrementing x from 0 to 1, and then exits because the condition x < 1 is false. The debug log outputs x = 1.
* D. 3: Incorrect. The loop does not run enough times to increment x to 3. It only runs once, setting x to 1.
Why Option C is Correct:
Option C (1) is correct because:
* The do-while loop executes the body (x++) exactly once, incrementing x from 0 to 1.
* The condition x < 1 evaluates to false when x = 1, causing the loop to exit after the first iteration.
* The System.debug(x) statement outputs the final value of x, which is 1.
* This behavior aligns with Apex loop semantics as defined in the Salesforce Apex Developer Guide.
Handling Typos:
* The code in the image contains a typo: "salesforce" is randomly inserted in the middle of the do-while loop. This appears to be an artifact of the image and not part of the intended code. For analysis, we ignore this text and treat the code as:
apex
Copy
Integer x = 0;
do {
x++;
} while (x < 1);
System.debug(x);
* There are no other syntactic issues in the code that affect the execution or outcome.
Example for Clarity:
To illustrate, here's how the code executes:
Integer x = 0; // x is 0
do {
x++; // First iteration: x becomes 1
} while (x < 1); // Condition: 1 < 1 # false, exit loop
System.debug(x); // Outputs: 1
If this code were run in a Salesforce org, the debug log would show:
DEBUG|1
