NEW QUESTION # 56
Instead of waiting to send emails to support personnel directly from the finish method of a batch Apex process, Universal Containers wants to notify an external system in the event that an unhandled exception occurs.
What is the appropriate publish/subscribe logic to meet this requirement?

A. Publish the error event using the Eventbus. publish () method.
B. Publish the error event using the addError method.
C. No publishing is necessary. Have the external system subscribe to the BatchapexErrorEvent.
D. Publish the error event with a Flow.

Answer: C

Use BatchApexErrorEvent for notifications. It's automatically triggered for unhandled exceptions in batch Apex. No need for manual publishing. External systems can subscribe to this event to receive notifications.

NEW QUESTION # 57
Universal Containers wants to use a Customer Community with Customer Community Plus licenses to allow their customers access to track how many containers they have rented and when they are due back. Universal Containers uses a Private sharing model for External users, Many of their customers are multi-national corporations with complex Account hierarchies. Each account on the hierarchy represents a department within the same business, One of the requirements is to allow certain community users within the same Account hierarchy to see several departments' containers, based on a custom junction object that relates the Contact to the various Account records that represent the departments.
Which solution solves these requirements?

A. A custom list view on the junction object with filters that will show the proper records based on owner
B. An Apex trigger that creates Apex managed sharing records based on the junction object's relationships
C. A Lightning web component on the Community Home Page that uses Lightning Data Services.
D. A Visualforce page that uses a custom controller that specifies without sharing [0 expose the records

Answer: B

Explanation:
For community users within the same Account hierarchy to see records based on a custom junction object, Apex managed sharing can be used. An Apex trigger can create sharing records based on the junction object relationships, allowing users to see records from different departments as required.

NEW QUESTION # 58

A. Event Monitoring Log
B. Asynchronous Data Capture Events
C. Developer Log
D. Calendar Events

Answer: A

Explanation:
Event Monitoring Log provides the ability to track different types of events in Salesforce, including user logins. These logs can be used to determine the last login time of a user without the need for real-time notification.

NEW QUESTION # 59
A developer has working business logic code, but sees the following error in the test class:
You have uncommitted work pending. Please commit or rollback before calling out.
What is a possible solution?

A. Use mast. T=RunningTes={} before making the callout to bypass it in test execution,
B. Rewrite the business logic and test classes with @Testvisible set on the callout.
C. Set seeAllData to true the top of the test class, since the code does not fall in practice.
D. Call support for help with the target endpoint, as It is likely an external code error.

Answer: C

Explanation:
The error "You have uncommitted work pending. Please commit or rollback before calling out" usually indicates that DML operations (like insert, update, delete) are being performed before a callout in a test context. This is not allowed because Salesforce does not support this sequence of operations in a single transaction. However, the use of seeAllData=true is generally not a recommended practice and does not address the core issue of mixed DML and callouts in tests. The correct solution is to use a mocking framework to simulate the callout response. By using Test.setMock(), developers can avoid performing actual callouts in test methods, thus bypassing the uncommitted work error.

NEW QUESTION # 60
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?
A)
B)

C)

D)

A. Option C
B. Option A
C. Option D
D. Option B

Answer: D

Explanation:
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.
