Salesforce Platform Developer II Sample Questions (Q154-Q159):

NEW QUESTION # 154
A developer has generated Apex code from a WSDL for an external web service. The web service requires Basic authentication.
What code should the developer use to authenticate?

A. Http.setHeader ('Authorization' , 'Basic QthZGprjpchVulHNchFtZQ!)
B. stub.authentication.put ('Authorization','Basic QthZGprjpchVulHNchFtZQ')
C. Http.setAuthentication('Basic QthZGprjpchVulHNchFtZQ')
D. stub.inputHttpHeaders_x.put('Authorization' , 'Basic QthZGprJpchVulHNchFtZQ')

Answer: D

NEW QUESTION # 155
Refer to the test method below:

The test method tests an Apex trigger that the developer knows will make a lot of queries when a lot of Accounts are simultaneously updated to be customers.
The test method fails at the Line 20 because of too many SOQL queries.
What is the correct way to fix this?

Answer: A

Explanation:
The correct way to fix this is to add Test.startTest() before and add Test.stopTest() after Line 18 of the code. This will reset the governor limits for the code that executes between these two methods, and allow the test to run without hitting the SOQL query limit. The Test.startTest() and Test.stopTest() methods are used to test code that makes a lot of queries or calls asynchronous methods12. By using these methods, the developer can isolate the code that needs more resources and verify that it does not exceed the governor limits.

NEW QUESTION # 156
Choose the correct definition for <apex:actionStatus>

A. Adds AJAX support to another component (e.g. onClick, onMouseUp, onFocus, etc.)
B. Sends an AJAX request according to the time interval you specify. If this ever gets re-rendered, it resets
C. Allows for controller methods to be called directly from Javascript. Must be encapsulated in
<apex:form> tags. Unlike actionSupport, these function<apex:actionPoller>s can be called directly from Javascript code
D. Can be associated with an AJAX request (actionFunction/actionSupport/actionPoller) and shows content conditionally depending on the status of the request (in progress/complete). Use the "id" field to specify name; use "status" field on related components to connect them
E. Signifies which components should be processed by the server when an AJAX request is generated

Answer: D

NEW QUESTION # 157
Business rules require a Contact to always be created when a new Account is created.
What can be used when developing a custom screen to ensure an Account is not created if the creation of the Contact fails?

NEW QUESTION # 158
A company has a web page that needs to get Account record information, such as name, website, and employee number. The Salesforce record 1D is known to the web page and it uses JavaScript to retrieve the account information.
Which method of integration is optimal?

A. Apex SOAP web service
B. Apex REST web service
C. SOAP API
D. REST API

Answer: A

Explanation:
The optimal method of integration for the scenario is an Apex SOAP web service. An Apex SOAP web service is a custom Apex class that exposes methods that can be invoked from an external system using SOAP protocol. An Apex SOAP web service can be used to expose Salesforce data and functionality to a web page that uses JavaScript, as long as the web page has access to the WSDL (Web Service Description Language) file that defines the web service. An Apex SOAP web service can also leverage the benefits of Apex, such as governor limits, testing, and debugging. A SOAP API is a standard Salesforce API that allows external systems to access and manipulate Salesforce data and metadata using SOAP protocol. A SOAP API can also be used to integrate with a web page that uses JavaScript, but it would require more coding and configuration than an Apex SOAP web service, as it would not be customized for the specific use case. An Apex REST web service is a custom Apex class that exposes methods that can be invoked from an external system using RESTful principles and JSON or XML formats. An Apex REST web service can also be used to integrate with a web page that uses JavaScript, but it would not be optimal for the scenario, as it would require the web page to parse the JSON or XML response and handle the authentication and authorization. A REST API is a standard Salesforce API that allows external systems to access and manipulate Salesforce data and metadata using RESTful principles and JSON or XML formats. A REST API can also be used to integrate with a web page that uses JavaScript, but it would not be optimal for the scenario, as it would require the web page to parse the JSON or XML response and handle the authentication and authorization.
