   A multinational company is designing a new WAN. They have a data center in the US and one in Europe. Each data center has a pair of Meraki MX appliances. The company has 50 branch offices globally, each with a single MX. The branches need to reach applications in both data centers. The network team wants to ensure that traffic from a branch in Asia to the US data center uses the best path, and that if the primary path fails, traffic is rerouted quickly. They also want to minimize the routing table size on the branch MXs. Which design should they choose?

   • ACreate a full mesh auto-VPN between all sites, and let the branch MXs learn all routes from both data centers.
   • BConfigure static routes on the branch MXs for each data center's subnets, with a floating static route for failover.
   • CUse OSPF on all MXs and configure the branches to peer with both data centers.
   • DUse a hub-and-spoke topology with the US data center as the primary hub and the European data center as a secondary hub. The branches connect to both hubs via auto-VPN.

   A managed service provider (MSP) is designing a multi-tenant network for several small businesses. Each tenant has its own Meraki MX appliance at their site, and they all connect to a central MX at the MSP's data center. The MSP wants to ensure that tenants cannot see each other's routes and that the routing tables on the central MX remain small. What is the best way to achieve this?

   • AConfigure a separate OSPF area for each tenant on the central MX.
   • BCreate a separate non-Meraki VPN tunnel for each tenant and use route filtering to only exchange the tenant's specific prefixes.
   • CUse a separate VLAN and subnet for each tenant on the central MX, and configure a static route for each tenant's subnet.
   • DUse Meraki auto-VPN for each tenant and configure the central MX to only advertise a default route to the tenants, while using route summarization for the tenants' subnets.
