300-415 Question 140
Single answerYou are tasked with deploying a new branch site in your SD-WAN network. The WAN Edge device at the branch needs to have OSPF configured for internal routing, while the device's interface IP addresses and system settings must be standardized across all branch sites. Which approach should you take to configure the device using Cisco vManage?
- A
Use a CLI template for the device to manually configure OSPF and system settings.
- B
Use a feature template for system settings and interface configurations, and a CLI template for OSPF.
- C
Use a feature template for all configurations, including OSPF, system settings, and interface configurations.
- D
Manually configure the device locally using CLI for OSPF and then sync it with vManage.
Show answer and explanation
Correct answer: B
Explanation
The best practice for configuring devices in Cisco SD-WAN is to use feature templates for standardized settings (e.g., system and interfaces) and CLI templates for more granular or specific configurations (e.g., dynamic routing protocols like OSPF). This approach ensures scalability, consistency, and efficient management.
- A. Incorrect.
Using a CLI template for all settings would make it possible, but it does not leverage vManage's centralized feature template capabilities, making it inefficient for standardized configurations.
- B. Correct.
This is the recommended approach. Feature templates can be used to standardize system and interface settings across multiple devices, while a CLI template can handle more granular configurations like OSPF if it cannot be fully defined via feature templates.
- C. Incorrect.
Using a feature template for all configurations is not practical in this scenario because OSPF configurations often require more flexibility than what feature templates provide.
- D. Incorrect.
Manual configuration defeats the purpose of using SD-WAN's centralized management capabilities and is not aligned with best practices.
