질문 # 146
How many Accounts will be inserted by the following block of code?

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

정답：A

설명：
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.

질문 # 149
When a user edits the Postal Code on an Account, a custom Account text field named "Timezone" must be updated based on the values in a PoataliCodeToTimezcone o custom object.
Which two automation tools can be used to implement this feature?
Choose 2 answers

A. Approval process
B. Account trigger
C. Quick actions
D. Fast Field Updates record-triggered flow

정답：B,D

설명：
To update the Timezone__c field on Account based on the Postal Code and values from PostalCodeToTimezone__c:
Option B: Account Trigger
An Apex trigger can query the PostalCodeToTimezone__c object and update the Timezone__c field when the Postal Code is changed.
A record-triggered flow that runs after the record is saved can perform a Get Records action to retrieve the matching PostalCodeToTimezone__c record and update the Timezone__c field.
Reference:
"Triggers enable you to perform custom actions before or after changes to Salesforce records."
- Apex Developer Guide: Triggers
Option D: Record-Triggered Flow (after-save)
"After-save flows can access other records and perform actions, such as create or update records."
- Salesforce Help: Record-Triggered Flows
Why Other Options Are Incorrect:
Option A: Quick Actions
Quick actions are initiated by the user and cannot automate field updates based on changes.
Option C: Approval Process
Approval processes are for record approval and are not suitable for automating field updates based on field changes.
