Answer: A

Explanation:

Performance Routing (PfR) delivers intelligent path control for application-aware routing across the WAN. PfR provides:

– Dynamic selection of the best path for application-based business policies

– Application-based load balancing across paths for full utilization of bandwidth with improved network availability

PfRv3 monitors application performance on a per-flow basis, and applies what is learned to select the best path for that application. Using smart-probe intelligence, flows are monitored passively; probes are sent only when specifically needed to further enhance efficiency. PfRv3 effectively load-balances across paths while delivering the best application-level SLA.

PfRv3 represents the third generation of enhancements to Cisco’s intelligent path control capabilities. It features simple, centralized configuration; improved application monitoring; higher scale; and faster convergence.

PfRv3 innovations include the introduction of enterprise domains, a capability for service orchestration in the network that enables centralized configuration, automatic discovery, and single-touch provisioning. Simply define the domain, configure the hub site, and PfRv3 does the rest.
