   A school's 'Capacity' SLE is below the target because many clients are experiencing slow throughput during class changes. The SLE dashboard shows that the affected clients are spread across multiple APs, and the RF health indicates high co-channel interference. What remediation action should the administrator take?

   • ARun a new RF optimization (e.g., adjusting channel and power settings) to reduce co-channel interference across the affected APs.
   • BIncrease the client's minimum data rate to force clients to connect at higher speeds.
   • CAsk the school to stagger class change times to reduce the peak client load.
   • DDisable the 5 GHz band on all APs to reduce the number of channels in use.

   How does Juniper Mist calculate SLE scores?

   • ABy aggregating client events and network data over a defined time window and comparing them against thresholds
   • BBy counting the number of failed client connections per hour
   • CBy using a fixed formula based on the number of access points in the site
   • DBy averaging the signal strength of all connected clients

   A university library reports that the 'Throughput' SLE has dropped to 70% during peak exam hours. The SLE dashboard shows the issue is isolated to a specific wing of the building. The drill-down reveals that the affected clients are all connected to one AP, and the RF health for that AP shows high channel utilization and frequent retries. What should the administrator do first?

   • AAdjust the AP's transmit power to reduce co-channel interference with neighboring APs.
   • BCheck the client devices for outdated drivers and recommend updates to the students.
   • CDisable the 2.4 GHz radio on the AP to force all clients to use 5 GHz.
   • DReplace the network cable connecting the AP to the switch to rule out a physical layer issue.

   A manufacturing plant's 'Successful Connection' SLE is at 90%, but the failure class breakdown shows that 80% of failures are DHCP-related. The DHCP server is on a different subnet than the APs, and the administrator suspects a DHCP relay issue. What should the administrator check first?

   • ACheck the client devices' Wi-Fi settings to ensure they are set to obtain an IP address automatically.
   • BInspect the DHCP server's scope for available addresses and lease duration.
   • CReview the AP's radio settings to ensure the SSID is broadcasting correctly.
   • DVerify that the DHCP relay agent is configured on the switch or router that connects the AP's subnet to the DHCP server's subnet.
