Which two WAN architecture choices improve scalability and reliability for a business network? (Choose two.)

Dual-homed branches improve both scalability and reliability by providing redundant connections to the core network. If one link or path fails, the other can take over, ensuring continued connectivity (reliability). This also allows for load balancing across multiple paths, which can handle increased traffic demands (scalability). Dynamic routing protocols automatically discover and maintain routes, adapting to network changes and failures. This enhances reliability by quickly rerouting traffic around outages and improves scalability by efficiently managing routes in large, complex networks without manual intervention. Asynchronous routing and static routing do not inherently provide these benefits; static routing requires manual updates for changes, and asynchronous routing refers to a different communication method, not a WAN architecture for redundancy. Single-homed branches offer no redundancy, making them less reliable and scalable.
