   A bank is deploying a new WAN link between two data centers and wants to verify that the link meets the required service-level agreements (SLAs) for latency and jitter before placing production traffic on it. Which assurance technique should be used?

   • APassive monitoring of the link's interface counters for errors and discards.
   • BSynthetic testing by generating test traffic between the two sites and measuring latency and jitter.
   • CAnalyzing NetFlow data from the existing production traffic.
   • DReviewing the router's routing table to confirm the link is in the path.

   In network design, what is the primary distinction between visibility and observability?

   • AVisibility is a property of the network devices, while observability is a property of the management platform.
   • BVisibility is achieved through monitoring tools, while observability is achieved through logging systems.
   • CVisibility is a real-time capability, while observability is a historical analysis capability.
   • DVisibility is the ability to collect data from the network, while observability is the ability to infer internal states from that data.
