   How can continuous network monitoring (a management plane activity) affect traffic flow?

   • AIt automatically adjusts QoS markings on all traffic
   • BIt can identify congestion or failures, prompting configuration changes that reroute traffic
   • CIt directly forwards packets faster by using dedicated hardware
   • DIt has no impact on traffic flow because it is passive

   A company is using policy-based routing (PBR) to steer traffic from a specific subnet to a WAN optimizer. The WAN optimizer is connected to a router via a separate interface. After implementing PBR, the network team notices that traffic from the subnet is not being optimized. What is the most likely cause?

   • AThe WAN optimizer is not in the same VLAN as the subnet.
   • BThe WAN optimizer is not configured with the correct routing table.
   • CThe router's routing table does not have a route to the WAN optimizer.
   • DThe PBR policy is applied to the wrong interface or in the wrong direction.

   In a network design, what is the primary effect of implementing link redundancy (e.g., multiple links between switches) on end-to-end traffic flow?

   • AIt eliminates the need for routing protocols
   • BIt increases the available bandwidth and provides failover capability
   • CIt reduces the number of devices in the traffic path
   • DIt guarantees that traffic will always take the shortest path
