   A network team recently changed the WAN optimization settings on the SD-WAN appliances to improve performance for a critical database application. After the change, users report that the application is performing worse. The WAN Clarity report shows that the database application's latency has increased, but throughput has also increased. What should the administrator do to validate the impact of the change?

   • ARevert the change immediately because latency increased
   • BCompare the WAN Clarity metrics before and after the change to see if the latency increase is consistent
   • CIncrease the bandwidth on the link to compensate for the increased latency
   • DCheck the WAN Clarity report for other applications to see if they are also affected

   A network team recently implemented QoS policies to prioritize VoIP traffic over bulk downloads at a branch site. After the change, users report that VoIP calls are still experiencing choppy audio. The WAN Clarity report for the site shows that the link is consistently at 95% utilization during business hours, with high jitter on the VoIP application. Which conclusion is most appropriate based on the WAN Clarity data?

   • AThe VoIP application is not being prioritized because the QoS policies were applied to the wrong interface
   • BThe jitter is caused by the broadband link, so the MPLS link should be checked
   • CThe link is overutilized, and the QoS policies may not be sufficient to guarantee VoIP quality
   • DThe QoS policies are not working because jitter is still high

   A network engineer is analyzing WAN Clarity reports for a site that has a 50 Mbps link. The report shows that the link is at 80% utilization, with an average latency of 10 ms and 0.1% packet loss. The engineer needs to determine if the link is healthy. What should the engineer conclude from this data?

   • AThe link is overutilized and may experience performance issues during peak times
   • BThe link is underutilized and should be upgraded
   • CThe link is unhealthy because of the high latency
   • DThe link is healthy because latency and packet loss are low
