NEW QUESTION 11
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-effective
Which WAN technology(ies) should be included in the design of company XYZ?

• A. 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.
• B. Internet should be the preferred option because it is cost effective and supports BFD, IP SL
• C. andIPsec for secure transport over the public Internet.
• D. Both technologies should be use
• E. Each should be used to back up the other one; where theprimary links are MPLS, the internet should be used as a backup link with IPsec (and vice versa).
• F. MPLS meets all these requirements and it is more reliable than using the Interne
• G. It is widelyused with defined best practices and an industry standard.

Answer: A
