Question 280

A branch identifies an evil-twin SSID but analysts never compare the fake authentication portal with the approved server certificate. What should the engineer investigate or configure next?

  1. Restrict active wireless containment to validated threats and legally approved policy scope
  2. Investigate wired attachment, inventory and physical location to determine the rogue-device category
  3. Analyze management frame origin, rate, protection status and client impact for potential attacks
  4. Investigate unauthorized SSID and authentication server identity together using WIDS evidence

Explanation

Correct Answer

D:

Wireless intrusion monitoring requires evidence-based classification of rogue, interfering and authorized devices and bounded response. In the described case, investigate unauthorized SSID and authentication server identity together using WIDS evidence resolves the identified control gap. Confirm with: The attack simulation identifies the fraudulent transmitter and a managed client rejects its false identity.

Incorrect Answers

A:

This is relevant to a separate wireless intrusion detection and prevention problem: An engineer enables automatic containment against every neighboring Wi-Fi network and disrupts legitimate third-party users. It does not directly address this incident, which instead calls for: Investigate unauthorized SSID and authentication server identity together using WIDS evidence.

Question 281

An office wants higher concurrent downlink throughput and assumes a single-stream laptop will receive four MU-MIMO spatial streams. Which response best follows from the observed evidence?

  1. Match spatial-stream expectations to the receiver's antenna and negotiated capability
  2. Validate supported drivers, regulatory region and security mode on the client before blaming the AP
  3. Keep compatible legacy service where necessary and plan an approved client replacement path
  4. Validate client PHY capabilities before expecting Wi-Fi 6 efficiency improvements on those scanners

Explanation

Correct Answer

A:

802.11 PHY capability is negotiated per client and is not conferred automatically by an AP marketing label. In the described case, match spatial-stream expectations to the receiver's antenna and negotiated capability resolves the identified control gap. Confirm with: The association record shows the single-stream limit and measured throughput aligns with that capability.

Incorrect Answers

B:

This is relevant to a separate 802.11 phy protocols problem: A Wi-Fi 6E site enables a 6 GHz SSID but leaves client operating-system drivers unable to recognize that band. It does not directly address this incident, which instead calls for: Match spatial-stream expectations to the receiver's antenna and negotiated capability.

C:
