Question 1

What is one requirement to keep in mind when including additional JavaScript 1h files in a Lightning Web Component?

AThe files must be ES6 modules and must have names that are unique within the component's folder.

BOnly five of the files can be used with an import statement

CAll the files must be imported to a singleton.js file and the singleton.js file can be used with an import statement

DOnly one of the files can be used with an import statement

Answer : A

When including additional JavaScript files in a Lightning Web Component, it is required that these files are ECMAScript 6 (ES6) modules and have unique names within the component's folder. This ensures proper module resolution and avoids namespace conflicts. Salesforce LWC documentation provides guidelines on organizing component resources, including JavaScript modules, to ensure they are correctly recognized and utilized within the LWC framework.

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

A developer used slots to pass content from one Lightning Web Component to another. How can they access the.

DOM for what was passed to those slots?

ACall this.template.querySelector() and this.template.querySelectorAll()

BCall this.querySelector() passing an id

CCall this.querySelector() and this.querySelectorAll()

DCall this.template.querySelector() passing an id

Answer : A

In Lightning Web Components, to access the DOM elements within the component's template, including those passed into slots, developers use this.template.querySelector() and this.template.querySelectorAll(). These methods allow for querying the component's local DOM. Direct DOM manipulation or querying outside the component's template is discouraged to maintain component encapsulation and security. For more information, see the Salesforce LWC documentation on accessing the DOM: Salesforce LWC DOM Access Documentation.

Question 7

Which two statements are accurate?

AA Lightning Web Component cannot contain an Aura component

BA Lightning Web Component can contain an Aura component

CAn Aura component can contain a Lightning Web Component which contains an Aura component

DAn Aura component can contain a Lightning Web Component

Answer : B, D

A Lightning Web Component can contain an Aura component, and an Aura component can contain a Lightning Web Component. This interoperability allows for a smoother transition from Aura to LWC and enables developers to utilize the strengths of both frameworks. However, nesting a Lightning Web Component within an Aura component which in turn contains a Lightning Web Component (Option C) is not a standard practice. For more information, refer to the Salesforce documentation on using Aura and Lightning Web Components together: Salesforce Aura and LWC Interoperability Documentation.
