A developer creates a batch Apex job to update a large number of records, and receives reports of the job timing out and not completing. What is the…

The first step in troubleshooting any asynchronous Apex job, including a Batch Apex job, is to check its status on the Apex Jobs page in Setup. This page provides a high-level overview of the job's execution, including its status (e.g., Queued, Processing, Failed, Completed), the number of batches processed, and any error messages. This initial check confirms if the job is failing or getting stuck and provides the context needed for deeper investigation, such as reviewing specific debug logs.

B. While debug logs are useful, the Apex Jobs page is the primary monitoring tool and the logical first step to get the job's overall status.

C. Disabling and recreating the job is a potential remediation step, not a troubleshooting step. You must first diagnose the problem.

D. Decreasing the batch size is a common solution for timeout issues, but it is a corrective action taken after troubleshooting, not the first diagnostic step.
