NEW QUESTION # 117
A developer sees test failures in the sandbox but not in production. No code or metadata changes have been actively made to either environment since the sandbox was created.
Which consideration should be checked to resolve the issue?
Answer: A
Explanation:
If test failures are occurring in a sandbox but not in production and there have been no active code or metadata changes, it could be due to differences in the Salesforce release versions between the two environments. Sandboxes can be on preview instances which get upgraded to new releases before production instances. This can lead to differences in behavior and could affect test executions. Ensuring that both the sandbox and production are on the same release can resolve such issues. API version differences and parallel testing settings typically do not cause discrepancies if the code hasn't changed, and while using SeeAllData=true is generally not recommended due to its dependence on the organization's data, it's unlikely to be the cause if the issue is related to the environment rather than the data.

NEW QUESTION # 118
A developer created a Lightning web component mat allows users to Input a text value that is used to search for Accounts by calling an Apex method. The Apex method returns a list of account to apply and is called imperatively from a JavaScript event handler.
Which two changes should the developer make so the Apex method functions correctly. Choose 2 answers
Answer: A,B
NEW QUESTION # 119
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?
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 # 120
Refer to the following code snippets:
A developer is experiencing issues with a Lightning web component. The component must surface information about Opportunities owned by the currently logged-in user.
When the component is rendered, the following message is displayed: "Error retrieving data". Which modification should be implemented to the Apex class to overcome the issue?
Answer: B
Explanation:
The @AuraEnabled(cacheable=true) attribute allows caching of method results on the client side, reducing server trips for already fetched data, which is useful for read-only data.
NEW QUESTION # 121
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: C
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.
