   A company uses SD-WAN to connect its headquarters to a remote office. The remote office uses a private IP range of 192.168.10.0/24, and the headquarters uses 192.168.10.0/24 for a different subnet. The two sites need to communicate, but the overlapping IP ranges cause routing conflicts. What should the administrator configure to resolve this issue?

   • AConfigure a security policy that allows traffic between the two sites without any NAT
   • BConfigure a QoS policy that prioritizes traffic between the two sites
   • CConfigure a source NAT policy on the remote office router to translate the remote office's source addresses to a non-overlapping range before sending traffic to headquarters
   • DConfigure a destination NAT policy on the headquarters router to translate the remote office's source addresses to a non-overlapping range

   A financial services firm runs a trading application over SD-WAN between two data centers. The application requires less than 50 ms latency and less than 1% packet loss. The current path policy prefers a direct internet link, but during peak hours the link experiences 80 ms latency. The team wants automatic failover to an MPLS backup path when the internet link degrades, and automatic return to the internet link when it recovers. What should the administrator configure?

   • AConfigure a QoS policy that prioritizes trading traffic and set the internet link as preferred without any performance thresholds
   • BSet the MPLS link as the preferred path and configure a performance policy with a latency threshold of 80 ms and action 'failover'
   • CSet the internet link as the preferred path and configure a performance policy with a latency threshold of 50 ms and a loss threshold of 1%, with action 'failover'
   • DConfigure a security policy that allows trading traffic and set the internet link as preferred with a static failover to MPLS

   What is the primary role of Quality of Service (QoS) in an SD-WAN environment?

   • ATo identify applications and users for security enforcement
   • BTo prioritize and shape traffic based on business needs
   • CTo select the best transport path for each application
   • DTo encrypt traffic between branch sites

   When designing security policies in SD-WAN, why is rule ordering important?

   • ABecause rules are applied in reverse order, so the last rule is most important
   • BBecause the first matching rule is applied, and later rules are not evaluated
   • CBecause rules must be ordered by the application they control
   • DBecause rules are applied in random order, so ordering ensures consistency

   In SD-WAN, when would you typically configure a destination NAT policy?

   • ATo allow internal users to access the internet using a public IP address
   • BTo prioritize traffic for a specific application
   • CTo forward inbound traffic from a public IP to an internal server
   • DTo select the best path for inbound traffic
