A company wants to detect rogue APs and automatically prevent unauthorized access to its WLAN. Which security feature should be enabled?

Question

Options

• AWireless Intrusion Prevention System (WIPS)
• BOpen Authentication
• CStatic VLAN Assignment
• DQoS Prioritization

• A
  95% (36)
• C
  3% (1)
• D
  3% (1)

Explanation

WIPS (Wireless Intrusion Prevention System) is the right choice because it is specifically designed to monitor the RF environment, identify rogue (unauthorized) access points, and take automated action to block or contain them - exactly what the question describes.

Why the others are wrong:

• Open Authentication (B) does the opposite - it allows any device to connect without credentials, which increases the attack surface rather than protecting against rogue APs.
• Static VLAN Assignment (C) segments network traffic but has no mechanism to detect or respond to unauthorized wireless devices.
• QoS Prioritization (D) manages bandwidth and traffic priority; it has nothing to do with security or unauthorized device detection.

Memory tip: Think of WIPS as a security guard that watches the airwaves (detection) and acts when something suspicious is found (prevention) - the "P" in WIPS stands for Prevention, which maps directly to "automatically prevent unauthorized access" in the question stem.
