What are the four common capability pillars typically leveraged to evaluate nextgeneration WAN solutions such as IWAN?
The correct answer is B. Transport-independent design, intelligent path control, application optimization, secure. Cisco's Intelligent WAN (IWAN) is built on four pillars: (1) Transport-Independent Design-the overlay works on any WAN transport (MPLS, Internet, 4G/LTE); (2) Intelligent Path Control-PfR dynamically selects the best path based on real-time performance metrics; (3) Application…

Explanation
Cisco's Intelligent WAN (IWAN) is built on four pillars: (1) Transport-Independent Design-the overlay works on any WAN transport (MPLS, Internet, 4G/LTE); (2) Intelligent Path Control-PfR dynamically selects the best path based on real-time performance metrics; (3) Application Optimization-WAAS/AppNav improves application performance over the WAN; and (4) Secure Connectivity-DMVPN with IPsec encrypts traffic across untrusted transports. 'Transport-dependent' (A), 'private connectivity' (C), and 'hybrid connectivity' (D) are not the official pillar terminology.
