300-415 Question 57
Select 3Your organization is deploying Cisco SD-WAN in a hybrid cloud environment. Part of the deployment strategy involves integrating SD-WAN with an IaaS provider to extend the WAN fabric into the cloud. Which of the following steps are necessary to successfully configure SD-WAN in an IaaS environment?
- A
Deploy vEdge Cloud routers in the IaaS provider's environment and configure them as branch devices.
- B
Establish a secure IPSec tunnel between the IaaS environment and the on-premises SD-WAN fabric.
- C
Leverage the IaaS provider's native network services instead of deploying vEdge or cEdge devices.
- D
Ensure that the IaaS environment supports Cisco SD-WAN controllers (vSmart, vBond, vManage) to manage connectivity.
- E
Configure BGP or static routes for proper communication between the IaaS environment and the SD-WAN fabric.
Show answer and explanation
Correct answers: A, B, E
Explanation
To extend SD-WAN into an IaaS environment, you need to deploy vEdge Cloud routers, establish secure tunnels, and configure appropriate routing protocols to integrate the IaaS environment with the SD-WAN fabric. Native network services of an IaaS provider do not replace SD-WAN appliances, and the controllers are typically not deployed within the IaaS environment.
- A. Correct.
Correct: Deploying vEdge Cloud routers in the IaaS provider's environment extends the SD-WAN fabric and allows the environment to act as a branch in the overall SD-WAN topology.
- B. Correct.
Correct: Establishing a secure IPSec tunnel ensures encrypted and secure communication between the IaaS environment and the on-premises SD-WAN fabric.
- C. Incorrect.
Incorrect: While IaaS providers may offer native network services, they are not a replacement for vEdge or cEdge devices in an SD-WAN deployment as these devices enable SD-WAN-specific features and policies.
- D. Incorrect.
Incorrect: Cisco SD-WAN controllers (vSmart, vBond, vManage) are typically deployed on-premises or hosted separately and are not required to be integrated directly into the IaaS environment.
- E. Correct.
Correct: Configuring routing protocols such as BGP or static routes ensures proper communication between the SD-WAN fabric and the IaaS environment.
