   An organization's SD-WAN bandwidth plan was designed six months ago. Since then, the company has adopted a new video conferencing tool that is heavily used. The network team has observed that video quality is poor during peak hours. They have reviewed the utilization reports and see that the video conferencing traffic is being marked as 'best effort'. What is the most appropriate action to optimize the bandwidth plan?

   • AMove the video conferencing traffic to a separate VLAN to isolate it from other traffic.
   • BLimit the video conferencing tool to a maximum of 2 Mbps per user to prevent it from consuming too much bandwidth.
   • CReclassify the video conferencing application as 'business-critical' and assign it a higher QoS priority and guaranteed bandwidth.
   • DIncrease the bandwidth on all WAN links to provide more capacity for the video conferencing tool.

   Which action is an example of optimizing a bandwidth plan?

   • ADisabling monitoring on the WAN links to reduce overhead
   • BRemoving all QoS policies to simplify the network
   • CIncreasing the bandwidth limit for a critical application that is experiencing packet loss

   A company's SD-WAN bandwidth plan was designed with a 100 Mbps MPLS link and a 200 Mbps broadband link. After a few months, the network team notices that the MPLS link is saturated during business hours, while the broadband link is underutilized. They also see that a large number of 'unknown' applications are consuming bandwidth on the MPLS link. What is the most appropriate first step to optimize the bandwidth plan?

   • AMove all traffic to the broadband link and use the MPLS link only for failover.
   • BIncrease the bandwidth on the MPLS link to accommodate the unknown traffic.
   • CBlock all unknown applications to prevent them from consuming bandwidth.
   • DIdentify and classify the unknown applications, then create policies to route non-critical ones to the broadband link.

   When assessing bandwidth requirements for different user groups, which approach best captures the needs of a remote sales team that uses video conferencing and CRM tools?

   • AProfile the sales team's application usage and measure their peak concurrent demand
   • BAllocate bandwidth based on the number of devices each user owns
   • CUse the same bandwidth estimate as the engineering team because both are remote
   • DMeasure the average bandwidth used by the entire company over a month

   During the bandwidth requirements assessment for an SD-WAN deployment, which factor is most important to quantify for each application category?

   • AThe average bandwidth used during off-peak hours
   • BThe physical distance between branch sites and the data center
   • CThe total number of applications in the enterprise
   • DThe peak concurrent bandwidth demand and the number of users per application
