Question 1

A company is implementing a new feature that requires updating a large number of records in Salesforce. The development team is considering using a trigger to handle the updates. However, they are concerned about governor limits and performance issues. They also have the option to use Batch Apex for this operation. Given the scenario, which approach would be the most efficient for processing 10,000 records, and what considerations should the team keep in mind regarding the use of triggers versus Batch Apex?

Accepted Answer

Use Batch Apex to process the records in manageable chunks, ensuring compliance with governor limits and optimizing performance.

Question 2

A developer is tasked with creating a custom Apex class that processes a large number of records from a custom object called `Order__c`. The class needs to handle bulk processing efficiently while ensuring that it adheres to Salesforce governor limits. The developer decides to implement a batch Apex job to manage the processing of these records. Which of the following statements best describes the key considerations the developer must keep in mind when designing this batch Apex job?

Accepted Answer

The batch class must implement the `Database.Batchable` interface and should handle the `start`, `execute`, and `finish` methods to manage the processing of records in manageable chunks, ensuring that the total number of records processed does not exceed the governor limits.

Question 3

A software development team is preparing for User Acceptance Testing (UAT) for a new Salesforce application. They have identified a set of critical business processes that need to be validated by end-users. The team plans to execute UAT over a two-week period, during which they will conduct multiple testing sessions with different user groups.

Accepted Answer

Implement a try-catch block around the SOAP call and log any exceptions, while also validating the input parameters before making the request.

Question 18

A company is preparing to implement a new feature in their Salesforce environment and is considering the use of a Full Sandbox for testing. They have a production environment with 100,000 records in their custom object and 50,000 records in their standard object. If they perform a refresh of the Full Sandbox, what will be the implications regarding data and metadata, and how should they approach the testing of the new feature to ensure a smooth deployment?

Accepted Answer

The Full Sandbox will include a complete copy of both data and metadata, allowing for comprehensive testing of the new feature in an environment that mirrors production.

Question 19

A developer is tasked with creating a custom Apex class that processes a large number of records from a custom object called `Order__c`. The class needs to handle bulk processing efficiently while ensuring that it adheres to Salesforce governor limits. The developer decides to implement a batch Apex job to process these records. Which of the following considerations should the developer prioritize to ensure optimal performance and compliance with governor limits during the execution of the batch job?
