In an SD-WAN architecture, what is the primary role of the underlay network?

To provide the logical topology and policy enforcement for application traffic

To provide physical or virtual transport connectivity between sites

To perform application-aware routing decisions

To encrypt all traffic between sites

How does SD-WAN segmentation help meet business and security requirements?

By encrypting all traffic with a single key

By creating isolated virtual networks with independent policies

By using separate physical routers for each department

By prioritizing traffic based on IP addresses only

When integrating SD-WAN with an existing MPLS network, what is a common migration strategy?

Use MPLS as the only transport for SD-WAN

Run SD-WAN in parallel with MPLS and gradually move traffic

Replace all MPLS circuits with internet immediately

Disable all routing protocols during migration

When designing a controller-based solution for a large enterprise, what is the primary reason to deploy multiple vSmart controllers?

To allow each vSmart to manage a separate routing domain

To increase the number of WAN edge devices that can be onboarded

To eliminate the need for vBond

To provide redundancy and scale for control-plane processing
