Question 1

Which technique is used by Lightning Web Components to provide areas of swappable, customizable content?

A<slot> elements

BJQuery templates

CMutationObservers

DCSS classes

Answer : A

Lightning Web Components (LWC) use <slot> elements to define areas within the component's template where content can be inserted dynamically. This feature, part of the Web Components standard, allows for the creation of customizable and reusable components. Salesforce developer documentation on LWC outlines the use of slots to build flexible component interfaces, enabling developers to design components that can adapt to various content structures and layouts.

Question 2

A developer suspects recent edits to a checkout flow have created a bug based on flow errors being emailed. Given the emails and some inputs known to trigger the issue, which two activities should the developer consider in their investigation?

AUse the Org Browser tool in the IDE to download the flow XML and run a diff report

BLook at the previous flow versions and compare them with the current one

COpen the Flow, Select Debug, Provide the Inputs, Select Run

DOpen the Flow and select Attach to Live Session, Provide the Session Id, Select Attach

Answer : B, C

To investigate a suspected bug in a checkout flow, comparing previous versions of the flow with the current one can help identify changes that might have introduced the bug. Additionally, Salesforce provides debugging capabilities within the Flow Builder, where a developer can select the debug option, provide input values known to trigger the issue, and execute the flow to observe its behavior, aiding in pinpointing the source of the problem.

Question 3

A developer suspects that a defect exists in 30 lines of Apex code. How can the developer add debug statements, run the block of apex code in isolation and observe the immediate results?

AClick the Check Out button in the storefront

BUse the Execute Anonymous window

CActivate Chrome dev tools and click the Check Out button in the Storefront

DUse the Execute Immediate window

Answer : B

To debug a specific block of Apex code, the Execute Anonymous window in the Salesforce Developer Console or an Integrated Development Environment (IDE) like Visual Studio Code with the Salesforce Extension Pack can be used. This tool allows developers to run Apex code snippets in isolation and observe the results immediately, which is valuable for identifying and resolving defects within specific code blocks.

Question 4

A developer needs to deliver a solution for taxation that supports multiple countries and a complex set of jurisdictions. Which three steps should be considered as part of this process?

AContact the vendor who wrote the third party service for the most recent information

BImplement the sfdc_checkout.CartTaxCalculations interface writing code from scratch

CImplement the sfdc_checkout.CartTaxCalculations interface calling out to a third party tax service

DImplement the sfdc_checkout.TaxCalculations interface calling out to a third party tax service

ELook for packages or existing sample code on the AppExchange

Answer : C, D, E

For a solution that requires handling complex tax calculations across multiple countries and jurisdictions, it's efficient to leverage third-party tax services that specialize in this area. Implementing the sfdc_checkout.CartTaxCalculations or sfdc_checkout.TaxCalculations interface to integrate with such a service ensures that tax calculations are accurate and up-to-date. Additionally, exploring the Salesforce AppExchange for packages or sample code can provide ready-made solutions or frameworks that can expedite the development process.

Question 5

A developer has just deployed a new Lightning Web Component to an authorized org. What should the developer do next to use the new component on apage?

AGo to 'Deploy LWC' in Setup.

BNavigate 3 to the Page, Click on the 'Custom Component Editor,' Click 'Publish' on the new component in the list and adjust the positioning.

CCreate a Metadata API (MDAPI) conversion file with the Command Line interface (CLI) then go to the page and adjust the positioning.

DGo to the page, edit it, and drag the new component onto the page.

Answer : D

After deploying a new Lightning Web Component (LWC) to an org, the typical next step to use the component on a page involves navigating to that page, entering the edit mode (usually through App Builder or a similar interface), and then dragging the new component from the components palette onto the desired location on the page. This process is consistent with Salesforce's modular design approach, allowing for easy integration and configuration of components within the Salesforce ecosystem.

Question 6

Which three are considered code units, or discrete units of work within a transaction in the debug logs?

AValidation rule

BApex class

CWeb service invocation

DLightning component load

EWorkflow invocations

Answer : B, C, E

In the context of Salesforce debug logs, code units represent discrete units of work within a transaction. Apex classes (B), Web service invocations (C), and Workflow invocations (E) are considered code units as they encapsulate specific operations or sets of logic that can be executed as part of a transaction. Validation rules (A) and the loading of Lightning components (D) are not considered discrete units of work in the same way, as they are part of the declarative interface and front-end framework, respectively. For more details on how Salesforce handles transactions and debug logs, refer to the Salesforce Developer Documentation: Salesforce Developer Documentation on Transactions and Debug Logs.

Question 7

A developer needs to debug a flow tracing a single input in complete detail, watching all variable changes as the checkout process is executed. Which feature should the developer enable? ~.

AShow the details of what's executed and render flow in Lightning Experience

BShow the details of what's executed and render flow in Lightning Runtime

CAdd watch to variables

DShow execution details inline

Answer : D

To debug a flow with detailed tracing of a single input, including watching all variable changes as the checkout process is executed, the developer should enable 'Show execution details' (inline) within the Flow Debugger. This feature allows developers to see a step-by-step execution of the flow, including the values of variables at each step. This is crucial for understanding how data is being passed through the flow and for identifying any issues. Salesforce documentation on debugging flows provides more information on this feature: Salesforce Flow Debugging Documentation.
