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?

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.
Universal Containers ne=ds to integrate with several external systems. The process Is Initiated when a record Is created in Salesforce, The remote systems do not require Salesforce to wait for a response before continuing.
What is the recommended best solution to accomplish this?
Answer : D
Platform events provide a robust and scalable way to communicate changes and events from Salesforce to external systems, especially when there is no requirement for Salesforce to wait for a response. They are designed to support event-driven architectures and can handle high volumes of events that can be published and consumed by external systems. Outbound messages, on the other hand, are limited by the need for an acknowledgment response from the target system, which can introduce latency.
Salesforce users consistently receive a "Maximum trigger depth exceeded'' error when saving an Account. How can a developer fix this error?
Answer : D
A common solution to the 'Maximum trigger depth exceeded'' error is to use a static variable in a helper class. The variable acts as a switch to ensure the trigger logic only executes once per transaction, preventing recursive trigger calls.
When developing a Lightning web component, which setting displays lightninglayout-items im one column on small devices, such as mobile phones, and in two
columns on tablet-size and desktop-size screens?
Answer : B
To display lightning-layout-items in one column on small devices and in two columns on larger devices, you should set the size attribute to '12' for small devices and the medium-device-size attribute to '6'. This ensures that on small devices each item takes the full width, and on medium or larger devices, items take up half the width.
A developer needs to implement a historical Task reporting feature that allows users, assigned to a custom profile named "Auditors", to perform searches against the Tasks related to the Account object.
The developer must ensure the search is able to return Tasks that are between 12 and 24 months old. It should exclude any tasks which have been deleted, and include Tasks whether archived or not.
Given the following code, which select statement should be inserted at the placeholder as a valid way to retrieve the Tasks ranging from L2 to 24 months old?
A.
B.
C.
D.
Answer : C
To retrieve Tasks that are between 12 and 24 months old, we need to use a SOQL query that filters based on the CreatedDate. The query must exclude deleted records and include both active and archived tasks. Since Tasks can be archived after a certain period (typically 12 months), we must ensure the query includes these as well.
Option C is correct because it uses ALL ROWS in the SOQL query, which includes both active and archived (soft-deleted) records. The query also correctly uses a range for CreatedDate to ensure it selects Tasks created between 12 to 24 months ago.
Option A is incorrect because it does not include the ALL ROWS keyword, which is necessary to include archived Tasks in the results.
Option B is incorrect because it only retrieves Tasks created in the last 12 months, not between 12 to 24 months ago.
Option D is incorrect because it does not filter Tasks based on their creation date correctly to include only those that are between 12 and 24 months old.
