Which additional factor can the embedded RRM software on Cisco WLC detect besides over-the-air metrics?

350-401 By islever Editorial Last updated Aug 1, 2026

Short answer

A presence of rogue APs or malicious SSIDs

Question

The Radio Resource Management software that is embedded in the Cisco WLC acts as a manager to constantly monitor over-the-air metrics. Which other factor does the Radio Resource Management software detect?

presence of rogue APs or malicious SSIDs Correct Answer
unauthorized wireless network access
repeated attempts to authenticate to a wireless network
end-node vulnerabilities

Key Takeaways

RRM's off-channel scans are designed to detect rogue APs and malicious SSIDs, not full access control or vulnerability scanning.

This question tests the extra detection capabilities of Cisco WLC's built-in Radio Resource Management (RRM) beyond basic over-the-air metric monitoring.

Common mistake: Many candidates mistakenly select Option C, confusing RRM's radio monitoring function with WLAN authentication event logging features.

Expert Analysis

Correct Option Justification

Option A is fully aligned with Cisco official specifications. The RRM embedded in Cisco WLC performs periodic off-channel scans, and the collected over-the-air packets are analyzed to identify the presence of rogue APs and malicious SSIDs, which is a defined built-in detection capability of RRM.

Incorrect Option Analysis

Option B: Unauthorized wireless network access is handled by dedicated WIPS and access control policies, not the core detection scope of RRM.
Option C: Repeated authentication attempts are logged and processed by WLAN security modules, not monitored by RRM's radio scanning mechanism.
Option D: End-node vulnerability scanning belongs to dedicated security assessment tools, which is completely outside RRM's functional boundary.

Related Technical Principle

RRM on Cisco WLC mainly focuses on RF resource management, including dynamic channel allocation, transmit power control, coverage hole detection, and the over-the-air rogue device detection specified in official documents. Its off-channel scan only occupies less than 0.2% of the total AP working time, ensuring no obvious impact on normal WLAN service performance.

Exam Strategy

Locate the keyword 'RRM detection', exclude non-radio scanning security functions, and match the official defined rogue detection feature.
