問題文
A bank carries the redo of a cross-region Exadata pair over the OCI network. Each region already holds a hub virtual cloud network with a local peering gateway and a dynamic routing gateway, and the remote peering connection between the two hubs reads peered. Which route table does the documented preparation put on the gateway attachment of each hub network, and what does it have the team read there?
選択肢
- The attachment keeps reading the default route table of the hub network, where a rule for the far client subnet is added and route propagation from the remote peering is switched on, because an attachment of this kind draws its routes from the table that the network itself carries.
- The attachment keeps the route table that the team wrote by hand when the attachment was created, whose rule sends the far client subnet to the dynamic routing gateway, since an attachment of this kind carries no route table until one is associated with it.
- The attachment is moved on to the autogenerated route table for the network attachments, and import route distribution is left enabled there, and it is set to the autogenerated distribution for all routes, so that the tighter arrangement is to leave the table for the remote peering, virtual circuit and network tunnel attachments with no distribution of its own.
- The attachment is moved on to the autogenerated route table for the remote peering, virtual circuit and network tunnel attachments, where import route distribution is left enabled and set to the autogenerated distribution for all routes, and the same note offers a tighter arrangement in which that distribution is dropped and a fresh one naming only the required remote peering attachment is written for the table that serves the network attachments.
