   A retail chain is evaluating its WAN links for SD-WAN. The current setup uses a 50 Mbps MPLS link at each store. The assessment team has collected link performance data over the past month. The data shows that the MPLS link utilization peaks at 80% during the last hour before closing, but averages only 30% for the rest of the day. The team is considering adding a broadband link to offload non-critical traffic. What is the most important factor to consider when evaluating the broadband link for this purpose?

   • AThe number of years the broadband provider has been in business.
   • BThe brand and model of the broadband modem provided by the ISP.
   • CThe monthly cost of the broadband link compared to the MPLS link.
   • DThe broadband link's actual sustained upload and download speeds, as well as its latency and jitter characteristics, compared to the MPLS link.

   A healthcare provider is assessing its network for SD-WAN. Traffic analysis shows that the electronic health record (EHR) application generates 70% of the traffic on the MPLS link to the data center. However, the team also notices that a large amount of backup traffic runs during business hours, consuming significant bandwidth. The EHR application is latency-sensitive, while the backup traffic is not. What should the assessment team recommend as the next step in the traffic flow analysis?

   • AConclude that the MPLS link is insufficient and recommend replacing it with a broadband connection.
   • BProfile the EHR application's specific bandwidth and latency requirements, and identify the backup traffic's source and destination to determine if it can be rescheduled or moved to a different link.
   • CFocus only on the EHR application and ignore the backup traffic since it is not latency-sensitive.
   • DRecommend immediately increasing the MPLS bandwidth to accommodate both the EHR and backup traffic during business hours.

   A media company is assessing its network for SD-WAN. The gap analysis reveals that the current MPLS links provide predictable latency, but the company wants to use SD-WAN to leverage cheaper broadband links. The traffic analysis shows that the company's video editing application is sensitive to jitter. The assessment team is evaluating whether the broadband links can meet the application's requirements. What is the most significant gap to address in the design?

   • AThe lack of a second data center for redundancy.
   • BThe need to purchase new broadband modems for each branch.
   • CThe cost savings from using broadband links instead of MPLS.
   • DThe potential for increased jitter on the broadband links, which could negatively impact the video editing application.

   What is the focus of a management and operations review in an SD-WAN assessment?

   • ATo inventory all physical servers
   • BTo review current network management practices and tools
   • CTo test the network's performance under load
   • DTo calculate the total bandwidth of all WAN links
