   An organization is using a vMX as a VPN concentrator in a hub-and-spoke AutoVPN topology. The vMX is deployed on a hypervisor with limited CPU resources. Several spokes are reporting slow throughput. What is the most likely cause?

   • AThe vMX is configured in NAT mode, which restricts VPN throughput.
   • BThe vMX is not licensed for Advanced Security, limiting VPN throughput.
   • CThe vMX's CPU resources are insufficient to handle the aggregate VPN traffic from all spokes.
   • DThe spokes are using a non-Meraki VPN client that is incompatible with AutoVPN.

   How can an administrator estimate the capacity of a vMX deployment?

   • ABy testing the vMX with maximum traffic to determine its limit.
   • BBy referring to the Meraki documentation for vMX sizing guidelines.
   • CBy using the same sizing as a physical MX of the same model.
   • DBy using the Meraki dashboard's built-in capacity planner.

   A company wants to deploy a pair of vMX appliances in active-passive high availability within the same cloud region. They need to ensure that if the active vMX fails, the passive one takes over with minimal disruption. What is a key requirement for this setup?

   • AThe passive vMX must be in a different availability zone to ensure failover.
   • BThe passive vMX must have a higher license tier than the active one.
   • CThe vMX pair must be configured in NAT mode to support HA.
   • DBoth vMX instances must be in the same subnet and share a virtual IP address.

   A network architect is estimating the throughput capacity of a vMX for a new site-to-site VPN deployment. The vMX will run on a KVM host with 4 vCPUs and 8 GB RAM. The expected traffic is 500 Mbps of encrypted traffic. What should the architect do to validate that the vMX can handle this load?

   • AIncrease the vMX's memory to 16 GB to ensure sufficient throughput.
   • BAssume the vMX will achieve the same throughput as a physical MX with similar specifications.
   • CConsult the Meraki documentation for vMX throughput ratings based on the allocated vCPU count.
   • DDeploy the vMX and run a speed test from a single branch to measure throughput.

   When deploying a vMX for site-to-site VPN, what is a primary consideration regarding performance?

   • AThe vMX can achieve maximum throughput regardless of the host hardware.
   • BThe vMX throughput is limited by the underlying host hardware and allocated resources.
   • CThe vMX performance is only affected by the number of VPN tunnels.
   • DThe vMX performance is identical to a physical MX of the same model.
