Which of the following best describes IWAN?
Options
- AThe IWAN allows transport-independent connectivity.
- BThe IWAN allows only static routing.
- CBecause only encrypted traffic is transported, application visibility is not possible with the IWAN.
- DThe IWAN needs special encrypting devices to provide an acceptable security level.

Explanation
Cisco IWAN (Intelligent WAN) is an enterprise WAN architecture designed to provide intelligent, application-aware connectivity across multiple transport types simultaneously-such as MPLS, public Internet, 4G/LTE, and broadband. Its defining characteristic is transport independence: traffic can flow over any available underlay transport and be dynamically steered based on application policy, path quality, and cost. IWAN does not restrict routing to static only; it uses dynamic protocols like EIGRP, BGP, and Performance Routing (PfR/PfRv3). Application visibility is a core IWAN feature through Application Visibility and Control (AVC). IWAN also runs on standard Cisco ISR/ASR routers-no specialized encryption appliances are required.
