Company XYZ is in the process of identifying which transport mechanism(s) to use as their WAN technology. Their main two requirements are.• a technology that could offer DPI, SLA, secure tunnels, privacy, QoS, scalability, reliability, and ease of management• a technology that is cost-effectiveWhich WAN technology(ies) should be included in the design of company XYZ?

Software-defined WAN should be the preferred choice because it complements both technologies, covers all the required features, and it is the most cost-effective solution.

Internet should be the preferred option because it is cost effective and supports BFD, IP SLA. and IPsec for secure transport over the public Internet.

Both technologies should be used. Each should be used to back up the other one; where the primary links are MPLS, the internet should be used as a backup link with IPsec (and vice versa).
