Which two WAN architecture options help a business scalability and reliability for the network? (Choose two)
The correct answer is C. dual-homed branches E. dynamic routing. Dual-homed branches enhance reliability by providing redundant connections, while dynamic routing improves scalability and resilience by automatically adapting to network changes and failures.

Why each option
Dual-homed branches enhance reliability by providing redundant connections, while dynamic routing improves scalability and resilience by automatically adapting to network changes and failures.
Asynchronous routing is a routing anomaly where traffic takes different paths in each direction and does not inherently contribute to network scalability or reliability.
Single-homed branches have only one connection to the WAN, creating a single point of failure that severely reduces reliability and limits scalability.
Dual-homed branches connect to the WAN with two distinct links or service providers, providing redundancy and higher availability, thus significantly improving network reliability and supporting scaling without a single point of failure.
Static routing requires manual configuration for every route and does not adapt to network changes or failures, making it poorly suited for large, scalable, or highly reliable WAN environments.
Dynamic routing protocols automatically learn and adapt to network topology changes, discover multiple paths, and reroute traffic around failures, which greatly improves network scalability by simplifying management and enhancing reliability.
