   A company has two sites with MX appliances. Each MX has a primary fiber link and a backup DSL link. The administrator wants to ensure that if the fiber link fails, all VPN traffic automatically fails over to the DSL link, and when the fiber link recovers, traffic should return to the fiber link. What configuration is needed?

   • ADisable dynamic path selection and configure static routes.
   • BSet the DSL link as primary and fiber as backup.
   • CEnable load balancing across both links.
   • DSet the fiber link as primary and DSL as backup, and enable 'Use primary uplink for all traffic'.

   How does Meraki dynamic path selection use the monitored link metrics to make routing decisions?

   • AIt randomly selects a path to distribute load evenly
   • BIt compares the metrics against configured thresholds and selects the path that best meets the application's requirements
   • CIt always uses the first configured uplink regardless of performance
   • DIt uses the metrics only for reporting and never for routing decisions

   A company has a hub-and-spoke VPN topology with a central MX as the hub and multiple branch MXs as spokes. Each branch has two WAN uplinks. The administrator wants to ensure that VoIP traffic from branches to the hub uses the best-performing path, while also ensuring that if the primary uplink at the hub fails, all traffic automatically fails over to the hub's backup uplink. What is the most efficient way to achieve this?

   • AEnable load balancing on both the hub and branches for all traffic.
   • BConfigure the branches' uplinks with primary/backup priority and enable 'Use primary uplink for all traffic' on the branches. Then create traffic shaping rules on the hub for VoIP with path preference 'Best path'.
   • CDisable dynamic path selection and configure static routes for VoIP traffic to use the hub's primary uplink.
   • DConfigure the hub's uplinks with primary/backup priority and enable 'Use primary uplink for all traffic' on the hub. Then create traffic shaping rules on the branches for VoIP with path preference 'Best path'.

   What is the primary purpose of dynamic path selection in a Meraki SD-WAN deployment?

   • ATo create a static routing table that never changes unless manually updated
   • BTo automatically route traffic over the best available WAN link based on real-time performance and application requirements
   • CTo encrypt all traffic between the branch and the internet
   • DTo replace the need for a firewall by inspecting all traffic at the edge

   In the Meraki dashboard, where would an administrator configure the uplink priorities that influence dynamic path selection?

   • AIn the 'Security & SD-WAN' section under 'Uplink preferences'
   • BIn the 'Network-wide' settings under 'General'
   • CIn the 'Organization' settings under 'Licensing'
   • DIn the 'Clients' page under 'Overview'
