3. Question 3 · 60 in bank

   You are working on a serverless DevSecOps application using Oracle Functions. You have deployed a Python function that uses the Oracle Cloud Infrastructure (OCI) Python SDK to stop any OCI Compute instance that does not comply with your corporate security standards. There are 3 non-compliant OCI Compute instances. However, when you invoke this function none of the instances were stopped. How should you troubleshoot this? (Choose the best answer.)

   • AThere is no way to troubleshoot a function running on Oracle Functions.
   • BEnable function logging in the OCI console, include some print statements in your function code and use logs to troubleshoot this.
   • CEnable function remote debugging in the OCI console, and use your favorite IDE to inspect the function running on Oracle Functions.
   • DEnable function tracing in the OCI console, and go to OCI Monitoring console to see the function stack trace.

   Show answer

   Answer: C

   Explanation

   Would go with B, for this time. Debugging would be in case of an error returned by the function. more info via https://docs.cloud.oracle.com/en-us/iaas/Content/Functions/Tasks/functionsexportingfunctionlogfiles.htm https://docs.cloud.oracle.com/en-us/iaas/Content/Functions/Tasks/functionstroubleshooting.htm

7. Question 7 · 60 in bank

   You are processing millions of files in an Oracle Cloud Infrastructure (OCI) Object Storage bucket. Each time a new file is created, you want to send an email to the customer and create an order in a database. The solution should perform and minimize cost. Which action should you use to trigger this email? (Choose the best answer.)

   • ASchedule a cron job that monitors the OCI Object Storage bucket and emails the customer when a new file is created.
   • BUse OCI Events service and OCI Notification service to send an email each time a file is created.
   • CSchedule an Oracle Function that checks the OCI Object Storage bucket every minute and emails the customer when a file is found.
   • DSchedule an Oracle Function that checks the OCI Object Storage bucket every second and emails the customer when a file is found.

   Show answer

   Answer: C

   Explanation

   Would go with B. Use Notifications to get notified when Event Rules are triggered or alarms are breached, or to directly publish a message. https://docs.cloud.oracle.com/en-us/iaas/Content/Notification/Concepts/notificationoverview.htm

   You are using Oracle Cloud Infrastructure (OCI) Resource Manager to manage your infrastructure lifecycle and wish to receive an email each time a Terraform action begins. How should you use the OCI Events service to do this without writing any code? (Choose the best answer.)

   • ACreate an OCI Notifications topic and email subscription with the destination email address. Then create an OCI Events rule matching "Resource Manager Stack "" Update" condition, and select the notification topic for the corresponding action.
   • BCreate an OCI Notifications topic and email subscription with the destination email address. Then create an OCI Events rule matching "Resource Manager Job "" Create" condition, and select the notification topic for the corresponding action.
   • CCreate a rule in OCI Events service matching the "Resource Manager Stack "" Update" condition. Then, select "Action Type: Email" and provide the destination email address.
   • DCreate an OCI Email Delivery configuration with the destination email address. Then create an OCI Events rule matching "Resource Manager Job "" Create" condition, and select the email configuration for the corresponding action.
