NEW QUESTION # 64
A developer is creating a Lightning web component to showa list of sales records.
The Sales Representative user should be able to see the commission field on each record. The Sales Assistant user should be able to see all fields on the record except the commission field.
How should this be enforced so that the component works for both users without showing any errors?
- A. Use Lightning Locker Service to enforce sharing rules and field-level security.
- B. Use Lightning Data Service to get the collection of sales records.
- C. Use WITH SECURITY_ENFORCED in the SOQL that fetches the data for the component.
- D. Use Security. stripInaccessible to remove fields inaccessible to the current user.
Answer: D
Explanation:
The correct answer is option B. Use Security.stripInaccessible to remove fields inaccessible to the current user.
This method takes a list of records and an access type (READ, UPDATE, CREATE, or UPSERT) and returns a new list of records with the inaccessible fields removed. This way, the Lightning web component can display the records without throwing any errors due to field-level security.
Option A is incorrect because WITH SECURITY_ENFORCED is a SOQL clause that enforces field-level security on all fields in the query. If the query returns any fields that the user does not have access to, the query will throw an exception. This is not desirable for the Lightning web component, as it will prevent the component from displaying any records at all.
Option C is incorrect because Lightning Data Service is a layer of Lightning web components that provides access to Salesforce data and metadata, cache management, and data synchronization. However, Lightning Data Service does not automatically handle field-level security for the records it retrieves. The developer still needs to use Security.stripInaccessible or another method to remove the inaccessible fields.
Option D is incorrect because Lightning Locker Service is a security feature that isolates Lightning web components from each other and from the rest of the page. It does not enforce sharing rules or field-level security for the data that the components access.

NEW QUESTION # 68
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. Rewrite all Visualforce pages asLightning components.
- B. Enable Available for Lightning Experience, Lightning Communities, and the mobile app on Visualforce pages used by the custom application.
- C. Incorporate the Salesforce Lightning Design System CSS stylesheet into the JavaScript applications.
- D. Set the attribute enableLightning to true in the definition.
Answer: C
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:
