   In an SD-WAN environment, which method is commonly used to allocate bandwidth to different applications on a WAN link?

   • AUsing Quality of Service (QoS) policies to define bandwidth limits and priorities per application
   • BSetting the same bandwidth limit for all applications to simplify management
   • CLetting each application automatically adjust its own bandwidth usage
   • DAssigning each application a fixed bandwidth based on its popularity

   A company's SD-WAN bandwidth plan is experiencing issues. The MPLS link is at 95% utilization during peak hours, and the broadband link is at 50%. The company has a critical ERP system and a non-critical backup system. The backup system is consuming 200 Mbps on the MPLS link. The network team has decided to move the backup system to the broadband link. However, after the change, they notice that the backup system is still consuming bandwidth on the MPLS link. What is the most likely reason for this?

   • AThe backup system is configured to use both links simultaneously.
   • BThe backup system is using a dynamic port, and the SD-WAN policy is not matching it correctly.
   • CThe routing policy for the backup system was not updated correctly, so it is still using the MPLS link.
   • DThe broadband link is not available, so the backup system is falling back to the MPLS link.

   A company has deployed SD-WAN and is monitoring bandwidth utilization. They notice that the MPLS link is consistently at 95% utilization during peak hours, while the broadband link is only at 40%. The company uses a mix of critical and non-critical applications. The network team wants to improve user experience without adding new links. What should they do first?

   • ADisable the broadband link and rely solely on the MPLS link to simplify management.
   • BMove non-critical traffic to the broadband link and implement QoS policies to prioritize critical traffic on the MPLS link.
   • CIncrease the bandwidth on the MPLS link to accommodate the peak traffic.
   • DImplement traffic shaping to limit all traffic on the MPLS link to 80% utilization.

   A company is planning a new SD-WAN deployment. They have identified the following application requirements: a critical ERP system that needs 100 Mbps, a VoIP system that needs 20 Mbps, and a non-critical video streaming service that needs 50 Mbps. The company has two links: a 150 Mbps MPLS link and a 300 Mbps internet link. The company also has a requirement to minimize costs. What is the most appropriate bandwidth plan?

   • APlace ERP and VoIP on the MPLS link, and video streaming on the internet link.
   • BPlace video streaming on the MPLS link, and ERP and VoIP on the internet link.
   • CPlace all applications on the MPLS link, and use the internet link only for failover.
   • DPlace ERP on the MPLS link, and VoIP and video streaming on the internet link.

   A company's SD-WAN bandwidth plan is not meeting performance requirements. The MPLS link is at 90% utilization, and the broadband link is at 40%. The company has a critical application that is experiencing high latency. The network team has identified that a non-critical application is consuming 150 Mbps on the MPLS link. They have decided to move the non-critical application to the broadband link. What is the most important next step to ensure the optimization is successful?

   • ADisable the non-critical application to prevent it from using the MPLS link.
   • BMonitor the utilization of both links after the change to ensure the critical application's performance improves.
   • CReconfigure the QoS policies to prioritize the non-critical application on the broadband link.
   • DIncrease the bandwidth on the MPLS link to provide more headroom.
