The two WAN architecture options that can help a business achieve scalability and reliability for its network are C. dual-homed branches and E. dynamic routing.

Dual-homed branches refers to the practice of connecting a branch office or location to two separate WAN connections, such as two different ISPs or two separate circuits from the same provider. By doing this, the business can achieve redundancy and failover capabilities, ensuring that if one connection fails, traffic can automatically be redirected to the other. This helps to increase network reliability and minimize downtime.

Dynamic routing, on the other hand, is a networking technique that allows routers to dynamically adjust the path that traffic takes through the network in response to changing network conditions. This is in contrast to static routing, where the path that traffic takes is pre-determined and does not change. Dynamic routing protocols, such as OSPF, BGP, and EIGRP, help to improve network scalability and reliability by automatically discovering and adapting to changes in the network topology, such as the addition or removal of network devices or links.

Asynchronous routing and static routing are not typically used to achieve scalability and reliability in WAN architectures. Asynchronous routing refers to a type of routing where packets are not delivered in the order in which they were sent, which is not particularly useful for most business networks. Static routing, while useful in certain situations, is not as flexible as dynamic routing and can be difficult to manage in larger networks.

In summary, dual-homed branches and dynamic routing are two WAN architecture options that can help businesses achieve scalability and reliability for their networks.
