300-415 Question 124
Single answerA financial organization is deploying Cisco SD-WAN in their environment and wants to ensure seamless communication between branch offices without pre-configured tunnels. They require on-demand secure tunnels that form dynamically based on application traffic patterns. Which feature of Cisco SD-WAN enables this functionality?
- A
Dynamic NAT
- B
Dynamic Tunnels using On-Demand Branch-to-Branch Connectivity
- C
Static Tunnels with Predefined IPsec Policies
- D
Dynamic Routing Protocols like OSPF or BGP
Show answer and explanation
Correct answer: B
Explanation
The correct answer is 'Dynamic Tunnels using On-Demand Branch-to-Branch Connectivity' because this feature enables Cisco SD-WAN to automatically create secure IPsec tunnels between branch offices when needed, based on application traffic patterns. This reduces administrative overhead and ensures efficient, secure communication between sites without requiring pre-configured tunnels.
- A. Incorrect.
Dynamic NAT is used for address translation but does not facilitate on-demand tunnel creation between branch offices.
- B. Correct.
Dynamic Tunnels using On-Demand Branch-to-Branch Connectivity is a key Cisco SD-WAN feature that allows secure tunnels to dynamically form between branches based on traffic needs, eliminating the need for pre-configuration.
- C. Incorrect.
Static Tunnels with Predefined IPsec Policies require manual configuration and do not provide the dynamic behavior required for seamless branch-to-branch communication.
- D. Incorrect.
Dynamic Routing Protocols like OSPF or BGP manage routing tables but do not facilitate the creation of secure, dynamic tunnels based on traffic patterns.
