In Salesforce B2C Commerce, when a custom log file reaches its file size limit, the system automatically handles the file to ensure continued logging without data loss:
* Option C: The current log file is archived and a new log file is created is the correct response. This process is part of the log file rotation mechanism implemented in the platform, ensuring that log files are kept to a manageable size and archived for record-keeping before starting a new file. This helps in maintaining performance and manageability of log files.
Option A is incorrect because the log file is not deleted but archived. Option B and D are inaccurate descriptions of the logging system's behavior regarding file size limits.
