NEW QUESTION # 174
A developer has the following requirements:
* Calculate the total amount on an Order.
* Calculate the line amount for each Line Item based on quantity selected and price.
* Move Line Items to a different Order if a Line Item is not in stock.
Which relationship implementation supports these requirements on its own?
Answer: B
Explanation:
* Why Re-Parentable Master-Detail Field?
* A master-detail relationship allows Line Items to roll up totals (e.g., calculate total amount) to the Order.
* Setting the relationship asre-parentablesupports moving Line Items between different Orders.
* Why Not Other Options?
* B. Lookup field: Does not support roll-up summary fields for calculations.
* C and D: Relationships in the opposite direction (Order to Line Item) do not support the required logic.

if (!RequestLogic.isValid(req)) {
req.addError('Your request cannot be created at this time.');
}

NEW QUESTION # 176
What is the result of the following code snippet?
public word doWork(Account acct) {
for (Integer i = 0; i <= 2007 i++) {
insert acct;
}
Answer: B
Explanation:
* The doWork method inserts an account for every iteration of the for loop, which runs from i = 0 to i <=
200, inclusive.
* This results in 201 iterations, and hence 201 accounts are inserted into the org.
Explanation of Code Behavior:
* The loop condition i <= 200 runs 201 times (0 to 200).
* The insert acct; statement is executed 201 times.
