NEW QUESTION # 66
Universal Containers wants to notify an external system in the event that an unhandled exception occurs when their nightly Apex batch job runs.
What is the appropriate publish/subscribe logic to meet this requirement?
- A. Have the external system subscribe to a custom Platform Event that gets fired with addError{).
- B. Have the external system subscribe to a custom
Platform Event that gets fired with EventBus.publish(1, - C. Have the external system subscribe to a standard
Platform Event that gets fired with with Eventbus.publish(1. - D. Have the external system subscribe to a standard Platform Event that gets fired.
Answer: B
Explanation:
To notify an external system in the event that an unhandled exception occurs when their nightly Apex batch job runs, the appropriate publish/subscribe logic is to have the external system subscribe to a custom Platform Event that gets fired with EventBus.publish(). A Platform Event is a special kind of Salesforce object that represents a business event that occurs in the system, such as a change in data, a system failure, or a user action. A Platform Event can be published by Apex code using the EventBus.publish() method, which sends the event message to the event bus. An external system can subscribe to a Platform Event using a CometD client or an Apex trigger, and receive the event message in near real time. The developer can create a custom Platform Event that contains the relevant information about the unhandled exception, and publish it using EventBus.publish() in the catch block of the Apex batch job. The external system can subscribe to the custom Platform Event and handle the notification accordingly. Having the external system subscribe to a standard Platform Event that gets fired with EventBus.publish() would not work, as there is no standard Platform Event that matches the requirement. A standard Platform Event is a predefined Platform Event that represents a system event, such as a login failure, a record change, or a user logout. Having the external system subscribe to a custom Platform Event that gets fired with addError() would not work, as the addError() method is used to display a custom error message on a record or a field, not to publish a Platform Event. Having the external system subscribe to a standard Platform Event that gets fired would not work, as there is no standard Platform Event that matches the requirement, and the Platform Event needs to be published explicitly using EventBus.publish().

NEW QUESTION # 67

NEW QUESTION # 68
A company has an Apex process that makes multiple extensive database operations and web service callouts.
The database processes and web services can take a long time to run and must be run sequentially.
How should the developer write this Apex code without running into governor limits and system limitations?
- A. Use Queueable Apex to chain the jobs to run sequentially.
- B. Use multiple 3zutuze methods for each process and callout.
- C. Use Apex Scheduler to schedule each process.
- D. Use Limits class to stop entire process once governor limits are reached.
Answer: A
Explanation:
Queueable Apex is suitable for complex processes that require chaining jobs to run sequentially. It can handle long-running processes without hitting governor limits, as each chained job runs in a new transaction with its own set of governor limits.

NEW QUESTION # 71
A developer created a Lightning web component that uses a lightning-record-edit-form to collect information about Leads. Users complain that they only see one error message at a time about their input when trying to save a Lead record.
What is the recommended approach to perform validations on more than one field, and display multiple error messages simultaneously with minimal JavaScript intervention?
- A. Apex trigger
- B. Validation rules
- C. External JavaScript library
- D. Try/catch/finally block
Answer: C
Explanation:
The recommended approach to perform validations on more than one field, and display multiple error messages simultaneously with minimal JavaScript intervention is to use an external JavaScript library. An external JavaScript library is a collection of reusable code that can provide additional functionality and features to the Lightning web component. The developer can use an external JavaScript library that supports form validation, such as jQuery Validation or Parsley.js, and import it into the Lightning web component. The developer can then use the library's methods and options to define the validation rules and messages for each field, and to display the errors on the component. Using a try/catch/finally block will not help, as it is used to handle exceptions and errors in the code, but it does not perform validations on the fields or display error messages. Using validation rules will not help, as they are used to enforce data quality and integrity on the server side, but they do not perform validations on the client side or display error messages on the component. Using an Apex trigger will not help, as it is used to execute logic before or after a record is inserted, updated, deleted, or undeleted, but it does not perform validations on the client side or display error messages on the component.
