   A retail company is evaluating its WAN links for SD-WAN. The current setup uses a 100 Mbps MPLS link at each store. The assessment team has collected performance data for the past three months. The data shows that the MPLS link has an average utilization of 40%, but during the holiday season, utilization spikes to 95% for two weeks. The company is considering replacing the MPLS link with a 1 Gbps broadband link. What is the most important factor to consider in the WAN link evaluation?

   • AThe broadband link's average utilization, which is likely to be lower than the MPLS link's average.
   • BWhether the broadband link can provide consistent performance during the holiday peak, including latency and jitter, not just raw bandwidth.
   • CThe broadband link's maximum bandwidth of 1 Gbps, which is ten times the MPLS link's bandwidth.
   • DThe cost savings from replacing the MPLS link with the broadband link.

   A fast-growing e-commerce company is planning an SD-WAN deployment. The company currently has 25 branch offices and expects to add 15 new offices in the next two years. The assessment team is evaluating the scalability of the current network. The current architecture uses a hub-and-spoke VPN model where all branch traffic goes through the data center. What is the most important scalability concern to address in the assessment?

   • AWhether the SD-WAN vendor offers a discount for purchasing appliances in bulk.
   • BWhether the new branch offices will have the same ISP as the existing offices.
   • CWhether the data center hub can handle the increased traffic and VPN termination load from the additional 15 branches.
   • DWhether the existing branch offices have enough physical space for new SD-WAN appliances.
