   An SD-WAN analytics platform is configured to automatically generate a ticket when link loss exceeds 5% for more than 10 minutes. A branch site experiences a 10-minute fiber cut, causing 100% loss, and a ticket is created. After the fiber is restored, the link returns to 0% loss. What should the administrator do to prevent unnecessary tickets for future transient outages?

   • AIncrease the duration threshold from 10 minutes to 30 minutes.
   • BDisable automated ticketing entirely.
   • CIgnore the ticket because the issue is resolved.
   • DIncrease the threshold to 50% loss.

   What does a sudden increase in packet loss on a primary WAN link, with no change in traffic volume, most likely indicate?

   • AA software bug in the SD-WAN controller that requires a reboot
   • BAn increase in application usage that is not yet visible in traffic reports
   • CA misconfigured firewall rule blocking all traffic
   • DA physical or environmental issue affecting the link, such as a faulty cable or interference

   An administrator reviews the weekly analytics report and notices that a branch site's 'Database' application traffic has a consistent 200 ms latency, while all other applications at the same site have under 50 ms latency. The link utilization is normal. What is the most likely cause indicated by this analytics pattern?

   • AThe Database server is located in a different country.
   • BThe site's firewall is blocking Database traffic.
   • CThe Database application is being routed over a suboptimal path.
   • DThe link is congested and needs more bandwidth.

   A university IT team needs to produce a report for the dean showing which departments (e.g., Engineering, Arts) consume the most bandwidth and which applications are driving that usage. The SD-WAN platform tags traffic by department based on source IP subnets. What is the most effective way to structure this report?

   • AA single report listing all applications sorted by total bandwidth, without department breakdown.
   • BA report grouped by department, with a sub-breakdown of top applications and bandwidth per department.
   • CA raw data export of all flows for the IT team to analyze manually.
   • DA report showing only the total bandwidth for the entire university.

   An administrator is troubleshooting a branch site where users report slow file transfers. The analytics show that the 'SMB' application has a throughput of 5 Mbps on a 100 Mbps link, but the link's utilization is 95% due to 'YouTube' traffic. The SMB traffic is marked as 'best effort' in QoS. What is the most effective configuration change based on this analytics?

   • AUpgrade the link to 200 Mbps.
   • BIncrease the QoS priority for SMB traffic to 'high' and set a bandwidth limit for YouTube.
   • CBlock all YouTube traffic at the site.
   • DMove SMB traffic to the secondary link.
