Which type of routing does Oracle FastConnect use to exchange routing information between on-premises networks and Oracle Cloud Infrastructure?
The exchange of routes is accomplished by industry standard BGP routing protocol.
What Azure admin roles are required for an Azure user to use the fully-automated onboarding op-tion for OracleDB for Azure?
The automated onboarding process requires that the Azure user onboarding to OracleDB for Az-ure have at least one of the following admin roles:
Application Administrator, Cloud Application Administrator, Privileged Role Administrator, or Global Administrator.
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 Oracle FastConnect circuit to Azure. The project manager has asked you to delete all resources involved in this cross-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?
To delete the interconnect, perform these steps in the order given. Failure to do so results in a failed state ExpressRoute circuit.
1. Delete the ExpressRoute connection. Delete the connection by selecting the Delete icon on the page for your connection.
2. Delete the Oracle FastConnect circuit from the Oracle Cloud Console.
3. Once the Oracle FastConnect circuit has been deleted, you can delete the Azure Ex-pressRoute circuit.
Hence 'You need to first delete the Oracle FastConnect circuit for the ExpressRoute circuit to be decommissioned, and then you can delete the ExpressRoute virtual circuit.' is the CORRECT AN-SWER.
How does Oracle Database Service for Azure enable bidirectional communication between applica-tions in the Azure tenancy and database resources in OracleDB for Azure?
With OCI multicloud's OracleDB for Azure, your database resources reside in an OCI account that is linked to your Azure account through Oracle Interconnect for Microsoft Azure, an Oracle-managed tunnel connection.
OracleDB for Azure configures DNS on both sides of the Interconnect to enable bi-directional communication between applications in the Azure tenancy and database resources in OracleDB for Azure.
What should you do to prepare your Oracle Cloud Infrastructure (OCI) Virtual Cloud Network (VCN) for potential security risks when connected to a Microsoft Azure VNet?
Controlling Traffic Flow Over the Connection
Even if a connection has been established between your VCN and VNet, you can control the packet flow over the connection with route tables in your VCN. For example, you can restrict traf-fic to only specific subnets in the VNet.
Controlling the Specific Types of Traffic Allowed
It's important that you ensure that all outbound and inbound traffic with the VNet is intended or expected and well defined. Implement Azure network security group and Oracle security rules that explicitly state the types of traffic one cloud can send to the other and accept from the other.
