56. Frage
A developer is building a Visualforce page that interacts with external services. Which interface should the developer implement to test this functionality? Choose 2 answers
Antwort: B,D
57. Frage
A company uses Salesforce to sell products to customers. They also have an external product information management (PIM) system that is the system of record for products.
A developer received these requirements:
* Whenever a product is created or updated in the PIM, a product must be created or updated as a Product? record in Salesforce and a PricebookEntry record must be created or updated automatically by Salesforce.
= The PricebookEntry should be created in a Priceboek2 that is specified in a custom setting.
What should the developer use to satisfy these requirements?
Antwort: C
Begründung:
Custom Apex REST services are the optimal solution for integrating Salesforce with an external PIM system.
When a product is created or updated in the PIM, the external system can make a REST call to a custom Apex REST endpoint in Salesforce, which then can create or update the Product2 and PricebookEntry records. This method allows using custom settings to determine the Pricebook2 dynamically.References: Apex Developer Guide - Exposing Apex Classes as REST Web Services
58. Frage
A developer needs to add code to a Lightning web component's configuration file so the component only renders for a desktop size form factor when on a record page.
What should the developer add to the component's record page target configuration to meet this requirement?
Antwort: D
Begründung:
When you want a Lightning web component to only render for a specific form factor, you can use the <targets
> tag within the component's .xml configuration file. To specify that the component should only appear on a desktop, you use the <targetConfig> tag with the targets="lightning__RecordPage" attribute and nest a < supportedFormFactors> tag inside it. Within this tag, you include a <supportedFormFactor> tag with the attribute type="Large".
Option B is the correct markup to ensure that the component only appears for the desktop form factor on a record page.

59. Frage
A company recently deployed a Visualforce page with a custom controller that has a data grid of information about Opportunities in the org. Users report that they receive a "Maximum view state size limit" error message under certain conditions. According to Visualforce best practice, which three actions should the developer take to reduce the view state?
Antwort: B,D,E
Begründung:
24
The Visualforc25e View State holds the state of the page (including controller variables) between server requests. It has a strict limit of 135KB. When a page handles large sets of data, like a grid of Opportunities, the view state can easily exceed this limit.
* Transient Keyword (Option A): This is the most effective programmatic way to reduce view state.
Marking a variable as transient prevents it from being serialized into the view state. This should be used for any data that is only needed for the current request and does not need to be maintained during a postback (e.g., large lists of records retrieved for a single display).
* Filters and Pagination (Option D): By using a StandardSetController or custom offset logic, the developer can limit the number of records held in memory at any given time. Instead of loading 5,000 Opportunities, the page can load and store only 20 records per page.
* Refine SOQL Queries (Option E): Developers often query "all" fields (e.g., SELECT * equivalent) or include large text areas that aren't displayed. By selecting only the specific fields required for the grid, the size of each object in the collection is reduced, directly lowering the view state.
Option B and C (private and final) affect variable visibility and immutability but do not prevent the variables from being serialized into the view state.
60. Frage
Which statement is considered a best practice for writing bulk safe Apex triggers?
Antwort: D
Begründung:
Bulk-safe triggers use collections to aggregate DML operations. This practice minimizes the number of DML statements, which is essential for bulk processing.References: Apex Developer Guide - Bulk Trigger Best Practices
