You are troubleshooting a wireless client’s issue and you suspect It Is related to DHCP latency.
In this scenario, which SLE should you review in the Mist Ul?
- A . Capacity
- B . Time to Connect
- C . Throughput
- D . Coverage
B
Explanation:
Identify the Problem: Suspected issue related to DHCP latency while troubleshooting a wireless
client.
Understanding SLEs:
Capacity: Related to the number of clients and bandwidth.
Time to Connect: Measures the time taken for clients to connect, including DHCP latency.
Throughput: Measures the data transfer rate.
Coverage: Measures the signal strength and coverage area.
Selecting the Appropriate SLE:
Time to Connect is the relevant SLE as it includes metrics on DHCP latency, which affects the connection time.
Review the SLE:
Analyze the Time to Connect SLE to identify any latency issues with DHCP.

Which Radio Resource Management (RRM) changes are only made once a day between 2:00 AM and 3:00 AM local time?
- A . channel and power settings across a site based on long-term statistics and baselines
- B . RF template changes to channel width
- C . channel and power level changes triggered by SSID scheduling
- D . channel and power level changes triggered by DFS events
A
Explanation:
Identify the Changes: Radio Resource Management (RRM) changes and their timings.
RRM Changes:
Channel and power settings based on long-term statistics.
RF template changes to channel width.
Changes triggered by SSID scheduling.
Changes triggered by DFS events.
Timing of Changes:
Long-term RRM changes to channel and power settings are typically scheduled once a day to avoid
disrupting network performance.
Conclusion:
Channel and power settings across a site based on long-term statistics and baselines are made once a
day between 2:00 AM and 3:00 AM local time.
