7. Question #7

   Your team has created a serverless application deployed in Oracle Functions. It uses a Python function leveraging the Oracle Cloud Infrastructure (OCI) Python SDK to stop any OCI compute instance that does not comply with your corporate security standards. Although there are three non-compliant OCI compute instances, when you invoke this function, none of the instances were stopped. With respect to this issue, which of the following is a valid troubleshooting strategy?

   • A. Enable function logging in the OCI console, add some print statements in your function code, and then view the logs to troubleshoot.
   • B. Enable function remote debugging in the OCI console, and then use your favorite IDE to inspect the function running on Oracle Functions.
   • C. Ensure that the application is deployed within the same OCI compartment as the instance, because you cannot enable function execution data from the OCI console.
   • D. Enable function tracing in the OCI console, and then go to the OCI Monitoring console to view the function stack trace.
