Refer to the exhibit. What does the MX Security Appliance send to determine whether VPN traffic exceeds the configured latency threshold in the VoIP custom performance class?
A.
1000-byte TCP probes every second, through VPN tunnels that are established over the primary WAN link.
B.
100-byte UDP probes every second, through VPN tunnels that are established over every WAN link.
C.
100-byte UDP probes every second, through VPN tunnels that are established over the primary WAN link.
D.
1000-byte TCP probes every second, through VPN tunnels that are established over every WAN link.
The answer is B refer to this documentation:
https://documentation.meraki.com/Architectures_and_Best_Practices/Cisco_Meraki_Best_Practice_Design/Best_Practice_Design_-_MX_Security_and_SD-WAN/Meraki_SD-WAN#Performance_Probes
Load balancing is disabled how could be over every WAN link?! Who using load balance for VoIP traffic? Best practice for VoIP traffics when we established over the primary WAN link. And definitely VoIP traffics using UDP not TCP.
The performance probe is a small payload (approximately 100 bytes) of UDP data sent over all established VPN tunnels every 1 second. MX appliances track the rate of successful responses and the time that elapses before receiving a response. This data allows the MX to determine the packet loss, latency, and jitter over each VPN tunnel in order to make the necessary performance-based decisions.
