NEW QUESTION # 62
How many Accounts will be inserted by the following block of code?

  • A. 150
  • B. 0
  • C. 1
  • D. 2
  • E. 3

Answer: C

Explanation:
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.
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.
Conclusion: Incorrect.
Option B: 0
Conclusion: Incorrect, as 150 accounts are inserted before hitting the limit.
Option C: 500
Conclusion: Incorrect, because the governor limit prevents more than 150 DML statements.
Option D: 150
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<Account> accountList = new List<Account>();
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:
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
Final answer:
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.
