Question
Recently, the WAN links between the headquarters and branch offices have been slow under peak congestion, yet multiple alternate WAN paths exist that are not always congested. What technology can allow traffic to be routed in a more informed manner to utilize transport characteristics such as delay, loss, or link load?
Options
- Aperformance routing
- Bstatic routing
- Con demand routing
- Dpolicy based routing

Explanation
Performance Routing (PfR), also known as Optimized Edge Routing (OER) in older Cisco documentation, dynamically monitors WAN transport characteristics - including delay, jitter, packet loss, and link load - and automatically shifts traffic to the best-performing available path. It provides intelligent, policy-driven path selection beyond what static or standard dynamic routing can achieve. Static routing cannot react dynamically to congestion. On-Demand Routing (ODR) is a minimal routing approach for hub-and-spoke stub networks. Policy-Based Routing (PBR) uses static administrator-defined rules and does not adapt to real-time network conditions.
