NEW QUESTION # 128
A developer is asked to develop a new AppFxchange application. A feature of the program creates Survey records when a Case reaches a certain stage and is of a certain Record Type. This feature needs to be configurable, as different Salesforce instances require Surveys at different times. Additionally, the out-of-the-box AppExchange app needs to come with a set of best practice settings that apply to most customers.
What should the developer use to store and package the custom configuration settings for the app?
Answer: A
Explanation:
Custom metadata is best for storing configurable settings. It's deployable, packageable, and upgradeable. Allows different configurations for different instances.
NEW QUESTION # 129
A developer wrote a trigger on Opportunity that will update a custom Last Sold Date field on the Opportunity's Account whenever an Opportunity is closed. In the test class for the trigger, the assertion to validate the Last Sold Date field fails.
What might be causing the failed assertion?
Answer: A
Explanation:
The test class may not be re-querying the Account record after updating the Opportunity, which is necessary to verify the updated field values. If the test does not query the database to get the most recent data after the trigger runs, it will not see the changes made by the trigger.
NEW QUESTION # 130
Refer to the test method below''
The test method calls a web service that updates an external system with Account information and sets the Accounts integration_Updated__c checkbox to True when it completes. The test fails to execute and exits with an error: "Methods defined as TestMethod do not support Web service callouts." A) B)
C)
D)
Answer: D
Explanation:
The correct order in tests with callouts is Test.startTest(), then Test.setMock(), followed by the method invocation, and finally Test.stopTest(). This ensures the mock callout is used.
NEW QUESTION # 131
The use of the transient keyword in Visualforce page controllers helps with which common performance issue?
Answer: B
Explanation:
The transient keyword in Visualforce page controllers marks variables that should not be part of the view state, which can significantly reduce the size of the view state. This can help avoid view state limit errors and improve page performance because a smaller view state requires less time to send to the client.
NEW QUESTION # 132
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?
Answer: A
Explanation:
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.
