NEW QUESTION # 97
Which code displays the contents of a Visualforce page as a PDF?
Answer: D
Explanation:
You can render any page as a PDF by adding the renderAs attribute to the <apex:page> component, and specifying "pdf" as the rendering service1. For example: <apex:page renderAs="pdf">. You can also use the PageReference.getContentAsPDF() method in Apex to render a Visualforce page as PDF data, and then use Apex code to convert that PDF data to an email attachment, a document, a Chatter post, and so on2.

NEW QUESTION # 98

Answer: C,D,E
NEW QUESTION # 99
For which three items can a trace flag be configured? Choose 3 answers
Answer: B,D,E
Explanation:
Trace Flags in Salesforce are used to set logging levels for various entities to debug and monitor execution. They can be configured for:
Apex Classes (Option C):
You can set a trace flag for a specific Apex class to monitor its execution and debug logs.
Reference:
Apex Triggers (Option B):
Similar to classes, trace flags can be set for Apex triggers to capture debug logs when the trigger executes.
Users (Option E):
Trace flags can be set for specific users to capture logs for all actions performed by the user.
This is useful for tracking issues specific to a user's experience.
Items Not Applicable:
Visualforce (Option A):
Trace flags cannot be directly configured for Visualforce pages.
While you can capture logs when a Visualforce page invokes Apex code, there is no direct trace flag for the page itself.
Flow (Option D):
Trace flags cannot be set directly on Flows.
Debugging Flows is done through different mechanisms like the Flow Debug logs and using the Flow Debug tool.
Conclusion:
Trace flags can be configured for Apex Classes (C), Apex Triggers (B), and Users (E).
NEW QUESTION # 100
A developer needs an Apex method that can process Account or Contact records.
Which method signature should the developer use?
Answer: C
NEW QUESTION # 101
Which annotation exposes an Apex class as a RESTful web service?
Answer: B
Explanation:
To expose an Apex class as a RESTful web service, you use the @RestResource annotation.
Option C: @RestResource(urlMapping='/myService/*')
@RestResource Annotation:
The @RestResource annotation is used to define an Apex class as a RESTful web service, specifying the URL mapping.
Methods within the class are annotated with @HttpGet, @HttpPost, @HttpPut, etc., to handle HTTP requests.
Example:
apex
Copy code
@RestResource(urlMapping='/myService/*')
global with sharing class MyRestService {
@HttpGet
global static String doGet() {
// Implementation
}
}
Reference:
"Use @RestResource to expose an Apex class as a RESTful web service."
- Apex Developer Guide: Exposing Apex Classes as REST Web Services
Why Other Options Are Incorrect:
Option A: @HttpInvocable
There is no @HttpInvocable annotation in Apex.
Option B: @RemoteAction
Used to expose methods to JavaScript in Visualforce pages, not for REST services.
"@RemoteAction methods enable you to call methods in Apex controllers from JavaScript code in a Visualforce page."
- Apex Developer Guide: Remote Action Methods
Option D: @AuraEnabled(cacheable=true)
Used to expose Apex methods to Lightning components, not for REST services.
Conclusion:
Using @RestResource with a URL mapping is the correct way to expose an Apex class as a RESTful web service.
