Question 1 of 30
In a Cisco SD-WAN deployment, a network engineer is tasked with configuring the vSmart Controllers to ensure optimal performance and security for a multi-branch environment. The engineer needs to determine the best approach to manage the control plane traffic between the vSmart Controllers and the branch routers. Given that the organization has multiple branches across different geographical locations, which of the following strategies would best enhance the reliability and efficiency of the control plane communication while ensuring secure data transmission?
Implementing a dedicated overlay network for control plane traffic, utilizing DTLS for encryption and ensuring that all control messages are sent over this secure channel.
Relying on the existing data plane for control plane traffic, allowing control messages to traverse the same paths as user data without additional encryption.
Configuring the vSmart Controllers to use a single point of presence for all control plane communications, minimizing the number of connections required.
Using a combination of static routing and manual configuration of control plane traffic paths to optimize performance without encryption.
