CWT Security Protocols & Network Optimization 4

Question 1

Which Wi-Fi security vulnerability involves an attacker creating a duplicate SSID and stronger signal to lure clients away from the legitimate AP?

Accepted Answer

Evil Twin attack

Answer

An Evil Twin AP mimics a legitimate SSID to perform a man-in-the-middle attack, intercepting client traffic.

Question 2

What does the Temporal Key Integrity Protocol (TKIP) use to improve upon WEP's weaknesses?

Accepted Answer

Per-packet key mixing and a message integrity check (Michael MIC)

Answer

TKIP added per-packet key mixing, a sequence counter, and the Michael MIC to address WEP's static key and integrity vulnerabilities.

Question 3

A wireless network uses 802.11ac Wave 2. A technician wants to maximize throughput by serving multiple clients simultaneously on the same channel. Which technology enables this?

Accepted Answer

MU-MIMO (Multi-User MIMO)

Answer

MU-MIMO introduced in 802.11ac Wave 2 allows an AP to transmit to multiple clients simultaneously using spatial stream separation.

Question 4

Which metric is used in 802.11k Neighbor Reports to help a client select the best AP to roam to?

Accepted Answer

RCPI (Received Channel Power Indicator) and RSNI (Received Signal to Noise Indicator)

Answer

802.11k Neighbor Reports include RCPI and RSNI values so clients can intelligently rank candidate APs before roaming.

Question 5

An organization mandates certificate-based mutual authentication for all wireless clients. Which EAP method best satisfies this requirement?

Accepted Answer

EAP-TLS

Answer

EAP-TLS requires both the client and server to present X.509 certificates, providing the strongest mutual authentication.
