   A retail company has deployed a new cloud-based POS application. Users report slow response times, but the network team cannot identify the bottleneck. Which monitoring approach would best help pinpoint the issue?

   • ACollect NetFlow data to analyze traffic flows and identify top talkers.
   • BUse SNMP to poll router CPU and memory utilization every 5 minutes.
   • CMonitor only the WAN link utilization and packet loss statistics.
   • DDeploy end-to-end application performance monitoring that measures response time at the client, network, and server segments.

   A company is migrating from a legacy hub-and-spoke WAN to a software-defined WAN (SD-WAN) with centralized control. After migration, users report that application performance is inconsistent, and monitoring shows that the control plane is consuming significant bandwidth on the underlay. Which design change is most likely to resolve the issue?

   • AReduce the frequency of control plane updates to lower bandwidth usage.
   • BImplement a separate management and control plane network, or use a dedicated VPN for control traffic.
   • CUse a different routing protocol for the underlay to reduce control traffic.
   • DIncrease the underlay bandwidth to accommodate both control and data traffic.
