Question 1 of 293

Which statement results in an Apex compiler error?

Map lmap = new Map([Select ID from Lead Limit 8]);

Date d1 = Date.Today(), d2 = Date.ValueOf('2018-01-01');

Integer a=5, b=6, c, d = 7;

List s = List{'a','b','c');

Correct Answer: A

The statement results in an Apex compiler error because 'Leas' is not a recognized type in Salesforce Apex. The correct type should be 'Lead'. This mismatch in type definition would cause a compiler error when attempting to create the map.

Question 2 of 293

What are two benefits of the Lightning Component framework? (Choose two.)

It simplifies complexity when building pages, but not applications.

It provides an event-driven architecture for better decoupling between components.

It promotes faster development using out-of-box components that are suitable for desktop and mobile devices.

It allows faster PDF generation with Lightning components.

Correct Answer: B, C

The Lightning Component framework provides two significant benefits. Firstly, it offers an event-driven architecture which ensures better decoupling between components, leading to more modular and maintainable code. Secondly, it promotes faster development by providing out-of-box components that are optimized for both desktop and mobile devices, allowing developers to build responsive and efficient applications.

Question 3 of 293

A method is passed a list of generic sObjects as a parameter.

What should the developer do to determine which object type (Account, Lead, or Contact, for example) to cast each sObject?

Use the first three characters of the sObject ID to determine the sObject type.

Use the getSObjectType method on each generic sObject to retrieve the sObject token.

Use the getSObjectName method on the sObject class to get the sObject name.

Use a try-catch construct to cast the sObject into one of the three sObject types.

Correct Answer: B

To determine the type of a generic sObject in Salesforce, the developer should use the getSObjectType method. This method returns an sObject token that identifies the type of the sObject (e.g., Account, Lead, or Contact). This approach is reliable and directly provides the needed information about the sObject type.

Question 4 of 293

What should a developer use to implement an automatic Approval Process submission for Cases?

An Assignment Rule

Scheduled Apex

Process Builder

A Workflow Rule

Correct Answer: C

To implement an automatic Approval Process submission for Cases, Process Builder is the best option. Process Builder allows for the automation of various business processes, including automatically submitting a record for approval based on defined criteria. It is designed for this type of automation and does not require complex coding like Scheduled Apex or Apex Triggers. Assignment Rules and Workflow Rules have more limited capabilities and are not specifically designed for automating approval submissions.

Question 5 of 293

When viewing a Quote, the sales representative wants to easily see how many discounted items are included in the Quote Line Items.

What should a developer do to meet this requirement?

Create a trigger on the Quote object that queries the Quantity field on discounted Quote Line Items.

Create a Workflow Rule on the Quote Line Item object that updates a field on the parent Quote when the item is discounted.

Create a roll-up summary field on the Quote object that performs a SUM on the quote Line Item Quantity field, filtered for only discounted Quote Line Items.

Create a formula field on the Quote object that performs a SUM on the Quote Line Item Quantity field, filtered for only discounted Quote Line Items.

Correct Answer: C

To meet the requirement, the developer should create a roll-up summary field on the Quote object that performs a SUM on the Quote Line Item Quantity field, filtered for only discounted Quote Line Items. Roll-up summary fields allow for the aggregation of data from child records (Quote Line Items) to a parent record (Quote), and can be filtered to include only specific records, such as those with discounts. This solution provides an efficient way to display the number of discounted items directly on the Quote object.
