350-401 Practice Question: Which three statements about RRM (Radio Resource…
Which three statements about RRM (Radio Resource Management) in a Cisco wireless LAN are true? (Choose three.)
Answer choices
Why each option matters
Answer the question above first, then reveal the full breakdown to understand why each option is right or wrong.
Correct answer & explanation
✓
RRM automatically selects the best channel for each AP based on interference measurements.
RRM dynamically adjusts channel and power settings based on RF measurements, uses a leader AP to coordinate, and can be configured to run at a scheduled interval. It does not require a dedicated hardware controller (it runs on the WLC) and does not automatically enable client load balancing (that is a separate feature).
Answer analysis
Option-by-option breakdown
For each option: why learners choose it and why it is or isn't the right answer here.
- ✓
RRM automatically selects the best channel for each AP based on interference measurements.
Why this is correct
Correct because RRM's Dynamic Channel Assignment (DCA) algorithm uses real-time RF data to assign channels with minimal interference.
- ✗
RRM requires a dedicated hardware controller to perform RF calculations.
Why it's wrong here
Incorrect because RRM runs as a software process on the Wireless LAN Controller (WLC) and does not require dedicated hardware.
- ✓
RRM can adjust the transmit power of APs to optimize coverage and reduce co-channel interference.
Why this is correct
Correct because RRM's Dynamic Transmit Power Control (DTPC) adjusts AP power levels based on coverage requirements and interference.
- ✓
RRM uses a leader AP to collect and distribute RF measurements to other APs in the same RF group.
Why this is correct
Correct because in an RRM RF group, one AP is elected as the leader to aggregate measurements and coordinate channel/power changes.
- ✗
RRM automatically enables client load balancing across APs in the same coverage area.
Why it's wrong here
Incorrect because client load balancing is a separate feature (e.g., using 802.11k/v or Cisco's own load balancing) and is not part of RRM.
