考题
Which two statements are true about the Wi-Fi Protected Access （WPA） and Wi-Fi Protected Access version 2 （WPA2） security solutions？（）A、both WPA and WPA2 require authentication support via IEEE 802.1 x and Pre-Shared Key （PSK）B、both WPA and WPA2 address all known Wired Equivalent Privacy （WEP） vulnerabilities in the IEEE 802.11i security implementationC、WPA is supported on client devices only. WPA2 is supported on both access point （AP） and client devicesD、WPA provides only a standard for authentication. WPA2 provides a standard for authentication and encryptionE、WPA requires encryption support via Temporal Key Integrity Protocol （TKIP） WPA2 provides encryption support via （symmetric block cipher）AES-CCMP
考题
What are three security problems with Wi-Fi Protected Access （WPA）？（）A、WPA is based on the outdated IEEE 802.11i standard.B、WPA uses RSN，which uses the same base encryption algorithm as RC4.C、WPA requires a hardware upgrade that may not be supported by all vendors.D、WPA uses TKIP，which uses the same base encryption algorithm as WEP.E、WPA is susceptible to a DoS attack when it receives two packets in quick succession with bad MICs，forcing the AP to shut down the entire Basic Service Set （BSS） for one minute.F、WPA is susceptible to a security weakness when preshared keys are used.
考题
Which two statements best describe enhanced wireless security encryption？（）A、TKIP protects RC4 encryption keysB、CKIP and TKIP protect AES encryption keysC、TKIP encryption is more processor intensive than AES encryption isD、WPA requires TKIP encryption， whereas WPA2 supports AES encryptionE、WPA requires AES encryption， whereas WPA2 supports TKIP encryption
