NEW QUESTION # 133
What are three capabilities of the <ltng : require> tag when loading JavaScript resources in Aura components?
Choose 3 answers
Answer: B,C,D
Explanation:
The <ltng : require> tag is a Lightning component that allows you to load external CSS and JavaScript libraries in your Aura components. The <ltng : require> tag has the following capabilities:
* One-time loading for duplicate scripts: The <ltng : require> tag ensures that the same script or style resource is loaded only once, even if it is specified in multiple <ltng : require> tags in the same component or across different components. This avoids unnecessary loading and potential conflicts.
* Specifying loading order: The <ltng : require> tag allows you to specify the order in which the scripts and styles are loaded, by using comma-separated lists in the scripts and styles attributes. The resources are loaded in the order you specify them, which is important for maintaining dependency order and avoiding errors.
* Loading externally hosted scripts: The <ltng : require> tag enables you to load scripts that are hosted on external servers, such as CDN or third-party services, by using the full URL of the script in the scripts attribute. This can be useful for accessing libraries that are not available as static resources in Salesforce.

NEW QUESTION # 134
A business has a proprietary Order Management System (OMS) that creates orders from their website and fulfills the orders. When the order is created in the OMS, an integration also creates an order record in Salesforce and relates it to the contact as identified by the email on the order.
As the order goes through different stages in the OMS, the integration also updates It in Salesforce. It is noticed that each update from the OMS creates a new order record in Salesforce.
Which two actions will prevent the duplicate order records from being created in Salesforce?

What Is the result of the following code?
Answer: C
NEW QUESTION # 137
Universal Containers has a Visualforce page that displays a table of every Container_c. being ....... Is falling with a view state limit because some of the customers rent over 10,000 containers.
What should a developer change about the Visualforce page to help with the page load errors?
Answer: A
Explanation:
To avoid exceeding the view state limit of 170 KB12, the developer should implement pagination with a StandardSetController. A StandardSetController allows the developer to display a set of records in a Visualforce page with built-in support for pagination, sorting, and filtering3. By using a StandardSetController, the developer can limit the number of records that are displayed and stored in the view state at a time, and provide navigation buttons for the user to access the next or previous set of records.
The other options are not correct because:
* A. Use Lazy loading and a transient List variable. This option is not effective, because lazy loading means that the data is loaded only when it is needed, but it still requires storing the data in the view state. A transient List variable is not included in the view state, but it also means that the data is lost
* after each request and has to be queried again, which can affect performance and consistency.
* B. Use JavaScript remoting with SOQL Offset. This option is not recommended, because JavaScript remoting does not support pagination, sorting, or filtering, and requires additional JavaScript code to handle the callbacks and display the data. SOQL Offset is also limited to 2,000 records, and can cause performance issues when used with large data sets.
* C. Implement pagination with an OffsetController. This option is not optimal, because an OffsetController is a custom controller that uses SOQL Offset to implement pagination. As mentioned above, SOQL Offset has limitations and drawbacks that make it unsuitable for large data sets.
