350-401 Question 41
Select 3A medium-sized enterprise wants to improve its network performance and gain better control over its WAN traffic. They are considering deploying an SD-WAN solution. Which of the following are benefits of implementing an SD-WAN solution in this scenario?
- A
Improved application performance through intelligent traffic routing
- B
Guaranteed 100% uptime due to complete elimination of WAN outages
- C
Enhanced visibility into network traffic and application usage
- D
Reduced operational costs by utilizing cheaper broadband links
- E
Eliminated need for any MPLS connectivity in the WAN
Show answer and explanation
Correct answers: A, C, D
Explanation
SD-WAN offers significant benefits such as improved application performance through intelligent traffic routing, enhanced network visibility, and cost savings by leveraging broadband links. However, it does not guarantee complete elimination of WAN outages or completely replace MPLS in all scenarios. Organizations can benefit from its flexibility, but limitations like dependency on link quality and partial reliance on traditional WAN technologies must be considered.
- A. Correct.
SD-WAN solutions improve application performance by intelligently routing traffic based on application policies and link quality, ensuring optimal user experience.
- B. Incorrect.
While SD-WAN can enhance reliability by using multiple transport links (e.g., broadband, LTE, MPLS), it cannot completely eliminate WAN outages, as link failures can still occur.
- C. Correct.
SD-WAN provides centralized management and enhanced visibility into network traffic and application usage, enabling better monitoring and troubleshooting capabilities.
- D. Correct.
SD-WAN allows the use of cost-effective broadband links alongside or instead of expensive MPLS circuits, reducing WAN operational costs.
- E. Incorrect.
SD-WAN does not necessarily eliminate MPLS connectivity; it is often used in hybrid WAN architectures alongside MPLS to balance performance and cost.
