A network engineer is troubleshooting intermittent data plane connectivity between two branch sites. The control plane is stable, and OMP routes are present. However, data traffic sometimes fails. What should the engineer investigate first?

The vSmart policy configuration

The OMP route next-hop reachability

The IPsec tunnel status between the edge devices

A branch office has two WAN links (MPLS and broadband) connected to a cEdge router. The cEdge router receives OMP routes from two remote sites via vSmart. The network team wants to ensure that traffic to a specific application uses the MPLS link when available, but fails over to broadband if the MPLS link is down. What must be configured on the cEdge router to achieve this behavior?

A policy that applies a SLA class to the application and sets backup TLOCs

A policy that sets the TLOC preference for the MPLS link

A policy that configures the broadband link as the primary TLOC

A policy that sets the preferred color for the application's OMP routes

A company has two data centers and multiple branches. They want to use Catalyst SD-WAN to provide active-active connectivity between the data centers and branches, with automatic failover if one data center becomes unreachable. They also want to avoid manual intervention. What is the best approach?

Configure a centralized data policy that sets TLOC preference and uses SLA classes for failover

Use OMP to advertise both data center prefixes with equal cost

Use vSmart to manually reroute traffic during failures

Configure all branches with a single TLOC to the primary data center

A network engineer is configuring a new branch cEdge router. The router has two WAN interfaces with different colors (MPLS and Internet). The engineer wants to ensure that the router advertises both interfaces to the vSmart controller so that remote sites can use either path. What must be configured on the cEdge?

A policy to redistribute both interfaces into OMP

A single TLOC with both interface IPs

Two OMP routes with different next hops

Two TLOCs, one for each interface, with distinct colors

A network engineer is deploying a Cisco Catalyst SD-WAN fabric for a company with 200 branch sites. The company requires that all control plane communications between the controllers and edge devices be encrypted, and that the edge devices automatically discover the controllers without manual IP configuration on each branch router. Which two components must be configured to meet these requirements?

vBond and vSmart with vManage for management
