   A developer has set up a scheduled job that exports order data to a downstream system via SFTP. The job runs successfully, but the downstream system reports that some orders are missing. What is the most effective way to trace the issue?

   • AAsk the downstream system to provide a list of all orders they received and manually compare.
   • BCheck the Business Manager job execution logs to see if the job completed successfully.
   • CAdd custom logging to the job to log the order IDs that are being exported, and compare them with the downstream system's records.
   • DCheck the SFTP server logs to see which files were uploaded.

   A developer is creating an OCAPI data endpoint for a downstream system to retrieve product data. The downstream system is an external partner that should only be able to access product data, not customer data. What is the most appropriate way to enforce this restriction?

   • ACreate a separate API client for the partner and assign it only the 'Product' resource permissions.
   • BCreate a custom controller that only exposes product data and use that for the partner.
   • CUse the same API client for all integrations and rely on the partner to only call the product endpoints.
   • DRestrict the partner's access by IP address and do not configure any API permissions.

   A developer is setting up an integration to send order data to a downstream fulfillment system. The downstream system is occasionally unavailable, and the business requires that no order data be lost. The integration should retry failed transmissions. What is the most reliable way to implement this?

   • AUse a synchronous web service call and if it fails, log the error and continue with the next order.
   • BSchedule a job that runs every hour and sends all orders created in the last hour, ignoring any failures.
   • CUse OCAPI to push the order data directly to the downstream system, and rely on the API's built-in retry mechanism.
   • DUse a message queue to buffer the order data, and have a worker process consume and send it to the downstream system with retry logic.
