Authentication and encryption in WPA, WPA2, and WPA3 — Quiz

Authentication and encryption in WPA, WPA2, and WPA3

1. Which WPA3-Personal feature directly addresses the vulnerability of dictionary attacks that exists in WPA2-Personal? (Choose one answer) a) The use of AES-256-GCMP for encryption b) The implementation of Protected Management Frames (PMF) c) The replacement of PSK with Simultaneous Authentication of Equals (SAE) d) The optional 192-bit cryptographic suite

2. What is the primary encryption and integrity algorithm mandated by the WPA2 standard? (Choose one answer) a) Temporal Key Integrity Protocol (TKIP) b) AES-Galois/Counter Mode Protocol (AES-GCMP) c) AES-Counter Mode with CBC-MAC Protocol (AES-CCMP) d) Simultaneous Authentication of Equals (SAE)

3. A network administrator needs to deploy a wireless network that meets modern enterprise security standards like PCI-DSS. Which mode should the administrator use? (Choose one answer) a) WPA2-Personal b) WPA3-Personal c) WPA-Enterprise d) WPA2-Enterprise or WPA3-Enterprise

4. What key security benefit does WPA3-Personal provide by ensuring that a compromised password cannot be used to decrypt previously captured traffic? (Choose one answer) a) Protected Management Frames (PMF) b) Forward Secrecy c) 802.1X Authentication d) Galois Message Authentication Code (GMAC)

5. Which of the following accurately describes a key difference in authentication between WPA/WPA2-Personal and Enterprise modes? (Choose one answer) a) Personal mode uses 802.1X/EAP, while Enterprise mode uses a pre-shared key b) Personal mode uses a pre-shared key, while Enterprise mode uses 802.1X/EAP with a RADIUS server c) Enterprise mode uses SAE, while Personal mode uses TKIP d) Both modes use PSK, but Enterprise mode adds a second factor
