   A managed service provider (MSP) is designing a network for a client with multiple sites. The client has a Meraki MX at each site and a central MX at their data center. The MSP wants to ensure that the client's routing tables are optimized and that the network is secure. They are considering using route summarization and filtering. What is the best way to implement this?

   • AUse auto-VPN and configure the central MX to advertise a default route to the branches, while using route summarization on the branches.
   • BConfigure route summarization on the central MX and use route filtering to only accept specific routes from the branch MXs.
   • CDisable dynamic routing and use static routes on all MXs.
   • DUse BGP on all MXs and configure route filtering and authentication.

   A company has a Meraki MX at its headquarters and several branch offices. The branches are connected via auto-VPN. The network team is planning to add a new subnet at the headquarters. They want to ensure that the new subnet is automatically advertised to the branches without manual configuration on each branch. What is the best way to achieve this?

   • AAdd the new subnet to the MX's local networks, and the auto-VPN will automatically advertise it to all branches.
   • BUse a non-Meraki VPN and manually configure the route advertisement.
   • CRun OSPF between the HQ MX and the branch MXs to propagate the new route.
   • DConfigure a static route on each branch MX for the new subnet.

   A company is deploying Meraki SD-WAN across its branch offices. Each branch has two WAN uplinks (MPLS and broadband). The network team wants to ensure that real-time traffic (e.g., VoIP) is sent over the MPLS link, while other traffic can use either link. They also want to ensure that if the MPLS link fails, the VoIP traffic can still be sent over the broadband link. What is the best way to configure this?

   • AConfigure a traffic shaping rule to prioritize VoIP traffic on the MPLS uplink, and set the broadband uplink as a backup.
   • BUse the SD-WAN traffic shaping rules to mark VoIP traffic, and configure the MX to prefer the MPLS uplink for this traffic, with failover to broadband.
   • CConfigure the MX to use the MPLS uplink as the primary for all traffic, and the broadband as a backup.
   • DSet up a separate VLAN for VoIP and route it via a static route to the MPLS uplink.

   What is the primary benefit of using deterministic path selection in a routing design?

   • AIt ensures that traffic always takes the same path regardless of network conditions
   • BIt automatically selects the shortest path to every destination
   • CIt provides predictable and consistent routing decisions based on defined metrics
   • DIt reduces the size of the routing table by summarizing routes
