A company wants to switch from static routing to a dynamic routing protocol to ease the administrative and operational overhead. The network topology is hub and spoke, and the branches use DMVPN back to the hub using two 100 Mbps internet connections. Both links must be used due to spikes in traffic, and routing must take traffic utilization of the links into account. Also, the branch routers have limited memory and CPU resources. Which routing protocol and design solution must the company choose?

Refer to the exhibit. A network engineer must design a BGP solution based on:
* The route reflector must have one or more direct physical connections to the core routers (R3 and R4).
* The route reflector must have full redundancy and avoid a single point of failure.
* R2 to R1 link utilization is 90%. and the remaining links are less than 50% utilized.
Which two solutions must the design Include? (Choose two.)
Which control-plane technology allows the same subnet to exist across multiple network locations?
What is the easiest way to enable SD-Access for all your remote sites after you have your campus SD-Access fabric up and running?

Refer to the exhibit An engineer is designing a hierarchical ISIS solution for an enterprise customer with these requirements
* Users in areas 25 and 55 send and receive traffic from both backbone areas
* Link flaps in areas 35 and 45 must not impact other areas
* Routers will double within the next 12 months in areas 35 and 45
Which design must the engineer select?
