Question
A retail company has several on-premises data centers which span multiple geographical locations. They plan to move some of their applications from on-premises data centers to Oracle Cloud Infrastructure (OCI). For these applications running in OCI, they still need to interact with applications running on their on-premises data centers to Oracle Cloud Infrastructure (OCI). for these applications running in OCI. they still need to interact with applications running on their on- premises data centers. These applications require highly available, fault-tolerant network connections between on premises data centers and OCI. Which option should you recommend to provide the highest level of redundancy?
Exhibit
Options
- AOracle cloud Infrastructure provides network redundancy by default so that no other operations are
- BIf your data centers span multiple, geographical locations, use only the specific IP address as a
- CSet up both IPSec VPN and FastConnect to connect your on premises data centers to Oracle
- DUse FastConnect private peering only to ensure secure access from your data center to Oracle
- ESet up a single IPSec VPN connection (rom your data center to Oracle Cloud Infrastructure since It

Explanation
If your data centers span multiple geographical locations, we recommend using a broad CIDR (0.0.0.0/0) as a static route in addition to the CIDR of the specific geographical location. This broad CIDR provides high availability and flexibility to your network design. For instance, the following diagram shows two networks in separate geographical areas that each connect to Oracle Cloud Infrastructure. Each area has a single on-premises router, so two IPSec VPN connections can be created. Note that each IPSec VPN connection has two static routes: one for the CIDR of the particular geographical area, and a broad 0.0.0.0/0 static route.
