24. Which of these is a good practice for a developer to follow when writing a trigger? Select all that apply.

Using @future methods to perform DML operations

Using the Map data structure to hold query results by ID

Using the Set data structure to ensure distinct records

Using synchronous callouts to call external systems

Explanation:

One of the best practices for Triggers is to bulkify the code. Set and map data structures are critical for successful coding of bulk triggers.

25. How can a developer determine, from the DescribeSObjectResult, if the current user will be able to create records for an object in Apex?

By using the IsInsertable() method

By using the IsCreatable() method

By using the hasAccess() method

By using the canCreate() method

Explanation:

isCreatable is used to check if a user has access to create records for an object.

26. Which of these is an accurate statement about variable scope? Select all that apply.

Parallel blocks can use the same variable name.

A variable can be defined at any point in a block.

Sub-blocks cannot reuse the variable name of a parent block.

Sub-blocks can reuse the variable name of a parent block if its value is null.

A static variable can restrict the scope to the current block if its value is null.

Explanation:

A variable can be defined at any point in a block. Parallel blocks can use the same variable name. However, sub-blocks cannot reuse the variable name of a parent block.

27. Which code block returns the ListView of an Account object using the following Debug statement? _x000D_system.debug(controller.getListViewOptions());_x000D_

ApexPages.StandardSetController controller = new ApexPages.StandardSetController(Database.getQueryLocator(Ã”SELECT Id FROM Account LIMIT 1Ã•));

ApexPages.StandardController controller = new ApexPages.StandardController([SELECT Id FROM Account LIMIT 1]);

ApexPages.StandardController controller = new ApexPages.StandardController(Database.getQueryLocator(Ã”SELECT Id FROM Account LIMIT 1Ã•));

ApexPages.StandardSetController controller = new ApexPages.StandardSetController([SELECT Id FROM Account LIMIT 1]);

Explanation:

One of the methods of the StandardSetController class is getListViewOptions.

2, 150

150, 2

11, 150

150, 11

Explanation:

getDMLStatements method shows you the number of DML calls that have been used so far._x000D__x000D_ getLimitsDMLStatements shows you the total number calls that can be made.

29. What is an accurate construction for a custom controller named ''MyController''?

Public MyController(List<SObject> objects){_x000D_accounts = (List<Account>)objects;_x000D_}

Public MyController(ApexPages.StandardController stdController){_x000D_account = (Account)stdController.getRecord():_x000D_}

Explanation:

Custom controllers don't have a parameterized constructor.

30. Which of the following is a valid Apex statement?

Private static constant Double rate = 7.75;

Account() acctList = new List<Account>{new Account()};

Integer w, x, y, = 123, x = Ã”abcÃ•;

The Opportunity StandardController for pre-built functionality

The StandardSetController to support related lists for pagination

A constructor that initializes a private Opportunity variable

A callback constructor to reference the StandardController

We can override the standard functionality of the standard buttons through Visualforce pages which use the same object's standard controller.

The field will not appear in the edit layout.

The user will see only masked characters, but can enter a new value and save it.

It will throw an error on changing that field and saving it.

The user will see only masked characters, but can enter a new value and save it.

Create a master-child relationship between them

Create a junction object to store both the values

Create a lookup relationship of candidate on position

To meet the specified requirement, the Position and Candidate objects need to be linked through a "many to many" relationship. In Salesforce, this is accomplished by creating a junction object.

34. A custom object has an organization-wide default setting of "Private" with Grant Access Using Hierarchies turned off. Which users can select the Sharing button on records for that object?

Only the record owner and a user with the System Administrator profile

The record owner, a user with the System Administrator profile, and a user shared to the record

The record owner, a user shared to the record, any user above the record owner in the role hierarchy, and a user with the System Administrator profile

The record owner, a user above the record owner in the role hierarchy, and a user with the System

Explanation:

Since the Grant Access using Hierarchies is un-checked, no user above the owner of the record in role hierarchy will be able to see the record._x000D__x000D_ Users below the owner of the record in the role hierarchy are not allowed to see it anyway._x000D__x000D_ OWD is private, hence only owners have the access to see the record.

Create the Interview score field as a picklist, displayed as a radio button on page layout

Create a formula field that displays the interview score as a set of radio buttons

Create the interview score field with a data type of radio button

Create a Visualforce page to display the interview score as a set of radio buttons

A validation rule with the VLOOKUP function

A formula field with the IF function

Explanation:

VLOOKUP can be used to validate data with the records in a custom object.

A custom Visualforce controller

A client-side S-control

Explanation:

Custom validations are written as part of the logic in a "before insert" Trigger.

38. How would a developer use Schema Builder to delete a custom field from an Account object that was required for prototyping but is no longer needed?

Remove all the references in the code and then the field will be automatically removed from Schema Builder

Mark the field for deletion in Schema Builder and then delete it from the declarative UI

Remove all references from the code and then delete the custom field from Schema Builder

Explanation:

Schema Builder is a good tool to view and make corrections in your database. But to delete a custom field, you need to first remove all the references of the field.

39. Where can custom roll-up summary fields be created using Standard Object relationships? Select all that apply.

On Opportunity using Opportunity Product records

On Account using Case records

On Campaign using Campaign Member records

On Account using Opportunity records

The Account should have a Lookup relationship to the Invoice.

The Account should have a Master-Detail relationship to the Invoice.

The Invoice should have a Master-Detail relationship to the Account.

Explanation:

In a master-detail relationship, the child object inherits all the properties of the master object.

Create a master-detail relationship in the Job Postings custom object to the Applications customer object

Create a lookup relationship on both objects to a junction object called Job Posting Applications

Create a lookup relationship in the Applications customer object to the Job Postings custom object

Explanation:

Create a method that performs a callout for a valid Account record, and call this method from within test methods.

Create a method that creates valid Account records, and call this method from within test methods.

Create a method that queries for valid Account records, and call this method from within test methods.

Create a method that loads valid Account records from a Static Resource, and call this method within test methods.

Explanation:

Account data passed to the test class should be modified according to the modified validation.

Parent-Child

Master-Detail

One-to-Many

Lookup

Explanation:

With a lookup relationship, child records can have distinct owners. With Master-Detail relationship, parent records become the owner of the child record. Since both Account and Warehouse are independent entities, there will be a lookup relationship between them.

Create a junction object to relate many engines to many parts through a master-detail relationship

Create a lookup relationship to represent how each part relates to the parent engine object

Create a master-detail relationship to represent the one-to-many model of engines to parts

Create a junction object to relate many engines to many parts through a lookup relationship

Explanation:

Since an engine can have multiple parts and a component can be a part of multiple engines, a Junction object needs to be created.
