   A company with multiple branch offices is experiencing poor performance for cloud-based applications. Each branch has two WAN links with different performance characteristics. The company wants to improve application performance without upgrading the WAN links. What is the most effective use of Meraki SD-WAN dynamic path selection?

   • AEnable dynamic path selection to route traffic over the best-performing link for each application based on real-time metrics.
   • BConfigure traffic shaping to prioritize all traffic equally.
   • CIncrease the bandwidth on the primary WAN link at each branch.
   • DDisable dynamic path selection and use static routing to send all traffic over the primary link.

   What is the first step an administrator should take when troubleshooting a dynamic path selection issue where traffic is not using the expected uplink?

   • AReboot the MX appliance to reset the routing table
   • BCheck the 'SD-WAN' page to review the current path selection and link performance metrics
   • CChange the uplink priorities to force traffic over the desired link
   • DDisable all traffic shaping rules to simplify the configuration

   A company is considering deploying Meraki SD-WAN to improve the performance of cloud-based applications accessed from multiple branch offices. Currently, all traffic from branches is backhauled to the headquarters over a single MPLS link. The company wants to reduce latency and improve resilience. What is the primary benefit of implementing dynamic path selection in this scenario?

   • AIt eliminates the need for a VPN concentrator at headquarters.
   • BIt automatically selects the best-performing path for each application based on real-time link metrics.
   • CIt replaces the need for WAN optimization appliances.
   • DIt guarantees zero packet loss on all links.

   A company has two offices connected via VPN. Each MX has a primary MPLS link and a backup broadband link. The MPLS link is preferred for its low latency, but the broadband link has higher bandwidth. The company wants to use both links simultaneously for different types of traffic: VoIP on MPLS and general internet traffic on broadband. What is the best way to achieve this?

   • AConfigure the VPN to use only the broadband link for all traffic.
   • BCreate traffic shaping rules for VoIP and general internet traffic, setting their path preferences to 'Primary uplink' and 'Backup uplink' respectively.
   • CEnable load balancing across both links for all traffic.
   • DSet the MPLS link as primary and broadband as backup, and enable 'Use primary uplink for all traffic'.
