NEW QUESTION # 19
Universal Containers has large number of custom applications that were built using a third-party javaScript framework and exposed using Visualforce pages. The Company wants to update these applications to apply styling that resembles the look and feel of Lightning Experience. What should the developer do to fulfill the business request in the quickest and most effective manner?
- A. Set the attribute enableLightning to true in the definition.
- B. Incorporate the Salesforce Lightning Design System CSS stylesheet into the JavaScript applications.
- C. Enable Available for Lightning Experience, Lightning Communities, and the mobile app on Visualforce pages used by the custom application.
- D. Rewrite all Visualforce pages asLightning components.
Answer: B
Explanation:
The Salesforce Lightning Design System (SLDS) is a CSS framework that provides a look and feel that is consistent with Lightning Experience1. By incorporating the SLDS CSS stylesheet into the JavaScript applications, the developer can apply the same styles and components that are used in Lightning Experience, without having to rewrite the entire application or change the underlying logic. This is the quickest and most effective way to update the custom applications to match the Lightning Experience UI.
The other options are not as quick or effective as option A. Option B would require rewriting all the Visualforce pages as Lightning components, which would be time-consuming and complex, especially if the applications use a third-party JavaScript framework that is not compatible with Lightning Web Components.
Option C is not valid, as there is no such attribute as enableLightning in the Visualforce page definition.
Option D would enable the Visualforce pages to be accessed from Lightning Experience, Lightning Communities, and the mobile app, but it would not change the appearance or behavior of the pages to match the Lightning Experience UI. References:

NEW QUESTION # 21
Universal Container uses Service Cloud with a custom field, stage_c, on the Case object.
Management wants to send a follow-up email reminder 6 hours after the stage_c field is set to '';Waiting on customer'' The .... Administrator wants to ensure the solution used is bulk safe.
Which two automation tools should a developer recommend to meet these business requirements?
Choose 2 answers
- A. Record_Triggered Flow
- B. Einstein Next Best Action
- C. Scheduled Flow
- D. Process Builder
Answer: A,C
Explanation:
* Scheduled Flow and Record-Triggered Flow are two automation tools that a developer can recommend to meet the business requirements of sending a follow-up email reminder 6 hours after the stage_c field is set to 'Waiting on customer'. They are both bulk safe, meaning they can handle large volumes of records without hitting governor limits12.
* Scheduled Flow is an automation tool that allows you to run a flow at a specific time or on a recurring
* schedule. You can use it to query the Case object for records that have the stage_c field set to 'Waiting on customer' and then send an email reminder to the case owner or the customer3 .
* Record-Triggered Flow is an automation tool that allows you to run a flow when a record is created or updated. You can use it to create a scheduled path that executes 6 hours after the stage_c field is set to
'Waiting on customer' and then send an email reminder to the case owner or the customer .
* Einstein Next Best Action and Process Builder are two other automation tools, but they are not suitable for meeting the business requirements. They are not bulk safe, meaning they can hit governor limits when processing large volumes of records12.
* Einstein Next Best Action is an automation tool that allows you to provide intelligent and contextual recommendations to users based on business rules and predictive models. It is not designed to send email reminders based on field values .
* Process Builder is an automation tool that allows you to create a process that performs actions when certain criteria are met. It can send email alerts, but it does not support time-based actions for record update triggers. It also has lower limits for the number of email alerts and scheduled actions than flows .

NEW QUESTION # 29
What should a developer use to fix a Lightning web component bug in a sandbox?
- A. Developer Console
- B. VS Code
- C. Force.com IDE
- D. Execute Anonymous
Answer: B
Explanation:
The best tool to use to fix a Lightning web component bug in a sandbox is VS Code with the Salesforce Extension Pack. VS Code is a powerful and popular code editor that supports many languages and features. The Salesforce Extension Pack provides a set of tools and commands to work with Salesforce metadata, such as Lightning web components, Apex classes, Visualforce pages, and more1. Using VS Code, a developer can create, edit, deploy, and retrieve Lightning web components from a sandbox, as well as debug them using breakpoints, watch expressions, and the console2. VS Code also integrates with other tools and services, such as Git, GitHub, Salesforce CLI, and Lightning Web Components Playground3.
The Developer Console is not the best tool to use to fix a Lightning web component bug in a sandbox, as it is mainly designed for working with Apex and Visualforce. The Developer Console does not support creating or editing Lightning web components, nor does it provide debugging features for them4.
The Force.com IDE is not the best tool to use to fix a Lightning web component bug in a sandbox, as it is deprecated and no longer supported by Salesforce. The Force.com IDE was an Eclipse-based IDE that allowed developers to work with Salesforce metadata, but it had limited support for Lightning web components and did not provide debugging features for them5.
The Execute Anonymous tool is not the best tool to use to fix a Lightning web component bug in a sandbox, as it is used to run arbitrary Apex code that is not saved as part of the application. The Execute Anonymous tool does not support creating or editing Lightning web components, nor does it provide debugging features for them6.
