The two WAN architecture options that help a business scalability and reliability for the network are:

C. Dual-homed branches: Dual-homing involves connecting each branch office to two or more different WAN links, such as two different service providers, in order to provide redundancy and increase reliability. This architecture option enables the business to maintain network connectivity even if one of the WAN links fails. In addition, it can also provide better performance and scalability by balancing traffic across the multiple links.

E. Dynamic routing: Dynamic routing protocols enable routers to dynamically exchange information about the network topology and find the best path for data to travel. This allows for faster convergence in case of network changes and improves network scalability by automatically adjusting to changes in the network. Dynamic routing protocols also increase network reliability by providing redundancy and failover mechanisms.
