1. On which object can an administrator create a roll-up summary field?

Any object that is on the master side of a master-detail relationship.

Any object that is on the parent side of a lookup relationship.

Any object that is on the detail side of a master-detail relationship.

Any object that is on the child side of a lookup relationship.

An administrator can create a roll-up summary field on any object that is on the master side of a master-detail relationship. This is because a roll-up summary field calculates values from related records and displays the result on the master record. In a master-detail relationship, the master record controls the behavior and access to the detail records, making it the appropriate object to create a roll-up summary field.

2. A developer runs the following anonymous code block: List<Account> acc = [SELECT Id FROM Account LIMIT 10]; Delete acc; Database.emptyRecycleBin(acc); system.debug(Limits.getDMLStatements()+ ', ' +Limits.getLimitDMLStatements()); What is the result?

11, 150

150, 2

150, 11

2, 150

The code block first queries for 10 Account records and stores them in the acc variable. Then, it attempts to delete the acc variable, which is not possible because it is a List and not an individual record. The code then tries to empty the recycle bin for the acc variable, but since it is not a record, this operation does not affect the recycle bin. Finally, the system.debug() statement outputs the number of DML statements used and the limit for DML statements, which is 2 and 150 respectively. Therefore, the result is 2, 150.

3. When the number of record in a recordset is unknown, which control statement should a developer use to implement a set of code that executes for every record in the recordset, without performing a .size() or .length() method call?

For (init_stmt, exit_condition; increment_stmt) { }

Do { } While (Condition)

For (variable : list_or_set) { }

While (Condition) { ... }

The correct answer is "For (variable : list_or_set) { }". This control statement is known as a "for-each" loop and is used to iterate through elements in a list or set without needing to know the size of the collection beforehand. It automatically handles the iteration and provides access to each element in the collection one at a time.

4. What is the result when a Visualforce page calls an Apex controller, which calls another Apex class, which then results in hitting a governor limit?

Any changes up to the error are saved.

Any changes up to the error are rolled back.

All changes before a savepoint are saved.

All changes are saved in the first Apex class.

When a Visualforce page calls an Apex controller, which in turn calls another Apex class, if hitting a governor limit occurs, any changes made up to the error will be rolled back. This means that any modifications or updates made before reaching the governor limit will not be saved and will be reverted back to their previous state.

5. What is the easiest way to verify a user before showing them sensitive content?

Sending the user a SMS message with a passcode.

Calling the generateVerificationUrl method in apex.

Sending the user an Email message with a passcode.

Calling the Session.forcedLoginUrl method in apex.

The easiest way to verify a user before showing them sensitive content is by calling the generateVerificationUrl method in apex. This method generates a verification URL that can be sent to the user. By clicking on the URL, the user can be redirected to a verification page where they can confirm their identity before accessing the sensitive content. This method eliminates the need for sending SMS or email messages with passcodes, making it a simpler and more efficient verification process.

7. On a Visualforce page with a custom controller, how should a developer retrieve a record by using an ID that is passed on the URL?

Use the constructor method for the controller

Use the $Action.View method in the Visualforce page

Create a new PageReference object with the Id.

Use the tag in the Visualforce page.

In order to retrieve a record by using an ID passed on the URL in a Visualforce page with a custom controller, the developer should use the constructor method for the controller. This method allows the developer to access the ID parameter from the URL and use it to query the record from the database. By retrieving the record in the constructor, the developer can then use it to populate the page fields or perform any necessary operations.

10. Which statement about the Lookup Relationship between a Custom Object and a Standard Object is correct?

The Lookup Relationship on the Custom Object can prevent the deletion of the Standard Object.

The Lookup Relationship cannot be marked as required on the page layout for the Custom Object.

The Custom Object will be deleted when the referenced Standard Object is deleted.

The Custom Object inherits security from the referenced Standard Objects

The correct answer is that the Custom Object will be deleted when the referenced Standard Object is deleted. This is because a Lookup Relationship creates a dependency between the two objects, where the Custom Object relies on the existence of the Standard Object. If the Standard Object is deleted, the Custom Object no longer has a valid reference and is also deleted.

11. A developer has the following code block: public class PaymentTax { public static decimal SalesTax = 0.0875; } trigger OpportunityLineItemTrigger on OpportunityLineItem (before insert, before update) { PaymentTax PayTax = new PaymentTax(); decimal ProductTax = ProductCost * XXXXXXXXXXX; } To calculate the productTax, which code segment would a developer insert at the XXXXXXXXXXX to make the value the class variable SalesTax accessible within the trigger?

SalesTax

PayTax.SalesTax

PaymentTax.SalesTax

OpportunityLineItemTngger.SalesTax

The SalesTax variable is defined as a public static variable within the PaymentTax class.

Since it is public static, it can be accessed using the class name PaymentTax followed by the variable name SalesTax.

Therefore, PaymentTax.SalesTax is the correct syntax to access the value of SalesTax within the trigger.
