Oracle Cloud Infrastructure 2022 Architect Professional — Question 1

A consulting company that employs Oracle Cloud Infrastructure (OCI) architects has successfully completed resource migration from Microsoft Azure to OCI, and no longer requires the OCI FastConnect circuit to Azure. The project manager has asked you to delete all resources involved in this inter-cloud connectivity. From the Azure side, you delete the Resource Group. After a while, you notice that all Azure resources have been deleted, except for the Azure ExpressRoute circuit.
What could be a potential reason for this issue?

Answer options

• A. You need to first delete the OCI FastConnect circuit for the ExpressRoute circuit to be decommissioned, and then you can delete the ExpressRoute virtual circuit.
• B. Your bill from the OCI side needs to be paid in full before you can remove the Azure ExpressRoute circuit.
• C. You need to remove all routes that point to the inter-cloud connection on both OCI and Azure before you can delete the circuit.
• D. You need to remove the Azure ExpressRoute Partner Service Key from the OCI FastConnect circuit, and then you can delete the ExpressRoute virtual circuit.

Correct answer: A

Explanation

The correct answer is A because the Azure ExpressRoute circuit relies on the OCI FastConnect circuit being deleted first to properly decommission. Options B and C are incorrect as billing issues or routes do not prevent the deletion of the ExpressRoute circuit. Option D is also wrong since the key removal is not a prerequisite for deleting the ExpressRoute virtual circuit.
