400-007 Question #97: Real Exam Question with Answer & Explanation
The correct answer is C: Improved operational efficiencies result In cost savings.. SD-WAN solutions are defined by centralized orchestration with zero-touch provisioning and deliver measurable cost savings through improved operational efficiency.
Question
SD-WAN can be used to provide secure connectivity to remote offices, branch offices, campus networks, data centers, and the cloud over any type of IP-based underlay transport network. Which two statements describe SD WAN solutions? (Choose two.)
Options
- ASD-WAN networks are inherently protected against slow performance.
- BControl and data forwarding planes are kept separate.
- CImproved operational efficiencies result In cost savings.
- DSolutions include centralized orchestration, control, and zero-touch provisioning.
- ESolutions allow for variations of commodity and specialized switching hardware.
Explanation
SD-WAN solutions are defined by centralized orchestration with zero-touch provisioning and deliver measurable cost savings through improved operational efficiency.
Common mistakes.
- A. SD-WAN improves application routing decisions and can prioritize traffic, but it cannot inherently prevent slow performance caused by insufficient underlying bandwidth or chronic network congestion.
- B. Separating the control and data forwarding planes is a foundational SDN principle that underlies SD-WAN, but it describes general SDN architecture rather than a specific differentiating feature of SD-WAN solutions.
- E. SD-WAN is specifically designed to run on commodity x86 hardware and abstract transport differences, so the use of specialized switching hardware is not a characteristic of SD-WAN solutions.
