Passed the exam. questions are valid. The customer support is top-notch. They were quick to respond to any questions I had and provided me with all the information I needed.

That's a big plus. I've used other dump providers in the past and the customer support was often lacking.

Answer:

Explanation:

Understanding the Code:

for (Integer i = 0 ; i < 500; i++) {

Account a = new Account (Name='New Account ' + i);

insert a;

}

What the Code Does:

Loops from i = 0 to i = 499 (total of 500 iterations).

In each iteration:

Creates a new Account record with the name 'New Account ' + i.

Performs an insert DML operation for each account.

Salesforce Governor Limits:

DML Statements Limit:

Maximum of 150 DML statements per Apex transaction.

[Reference: Apex Governor Limits - DML Statements, , Analyzing the Code Against Limits:, Number of DML Statements Used:, The code performs one DML statement per iteration., Total DML statements attempted: 500., Governor Limit Exceeded:, After 150 DML statements, the code exceeds the limit., At the 151st insert, a LimitException is thrown., Number of Accounts Successfully Inserted:, Only the first 150 accounts are inserted before the exception halts execution., , Option Analysis:, Option A: 100, Explanation: This would imply a limit at 100 DML statements, which is incorrect., Conclusion: Incorrect., , Option B: 0, Explanation: This would suggest that no accounts are inserted, possibly due to an exception thrown before any DML operations., Conclusion: Incorrect, as 150 accounts are inserted before hitting the limit., , Option C: 500, Explanation: This would mean all accounts are inserted successfully., Conclusion: Incorrect, because the governor limit prevents more than 150 DML statements., , Option D: 150, Explanation: Matches the maximum allowed DML statements before hitting the governor limit., Conclusion: Correct., , Optimizing the Code:, Bulk DML Operations:, Best Practice: Perform DML operations on lists rather than individual records to reduce the number of DML statements., Optimized Code:, , List accountList = new List();, for (Integer i = 0 ; i < 500; i++) {, Account a = new Account (Name='New Account ' + i);, accountList.add(a);, }, insert accountList;, Benefits:, Only one DML statement is used (insert accountList)., All 500 accounts are inserted successfully., Reference: Apex Developer Guide - Bulk DML Operations, , Final Answer:, D. 150, , Additional Notes:, Governor Limits Enforcement:, Salesforce enforces governor limits to ensure efficient use of resources in a multi-tenant environment., Exceeding limits results in a runtime exception (System.LimitException) that cannot be caught., Exception Handling:, In this scenario, a System.LimitException is thrown, which cannot be handled by try-catch blocks., Reference: Apex Developer Guide - Uncatchable Exceptions, Best Practices Summary:, Use Collections for DML Operations: Process records in bulk using lists or maps., Avoid Loops with DML Statements: Do not place DML operations inside loops., Reference: Apex Developer Guide - Best Practices for DML Operations, ]
