   A hospital's 'Availability' SLE is 99.9%, but the 'Roaming' SLE is 70%. The team changed the AP neighbor list (enabled/disabled specific channels) to improve roaming. After the change, the Roaming SLE improved to 85%, but the 'Capacity' SLE dropped from 90% to 80%. Which conclusion is most accurate?

   • AThe change had no effect; the capacity drop is due to a new client device type
   • BThe change improved roaming but may have introduced co-channel interference, reducing capacity
   • CThe change was counterproductive; the capacity drop outweighs the roaming improvement
   • DThe change was successful; the capacity drop is unrelated to the roaming change

   What is the primary purpose of Service Level Expectations (SLEs) in Juniper Mist wireless assurance?

   • ATo automatically configure access points based on network traffic patterns
   • BTo define a set of user-defined metrics that measure the quality of the wireless experience from the client's perspective
   • CTo provide a real-time packet capture tool for deep inspection of wireless traffic
   • DTo replace the need for traditional network monitoring tools by providing raw syslog data

   In Juniper Mist, what role do Service Level Expectations (SLEs) play in wireless assurance?

   • AThey are used only for reporting to management and have no operational impact
   • BThey replace the need for configuration management of access points
   • CThey automatically remediate wireless issues without administrator intervention

   A company's 'Throughput' SLE is 88%. The team changes the client minimum data rate from 12 Mbps to 24 Mbps to reduce airtime consumption. After the change, the Throughput SLE improves to 93%, but the 'Coverage' SLE drops from 95% to 90%. Which assessment of this change is most accurate?

   • AThe change had no effect on coverage; the drop is due to a temporary RF interference issue
   • BThe change was counterproductive; the coverage drop outweighs the throughput gain
   • CThe change was successful; the coverage drop is acceptable because throughput is more important
   • DThe change improved throughput by reducing low-rate frames, but it reduced coverage because clients at the edge can no longer associate
