CWSP-205 practice questions, page 3 of 5, with answer review and explanations.

Question 11

In order to acquire credentials of a valid user on a public hot-spot network, what attacks may be conducted? Choose the single completely correct answer.

  1. Social engineering and/or eavesdropping
  2. RF DoS and/or physical theft
  3. MAC denial of service and/or physical theft
  4. Authentication cracking and/or RF DoS
  5. Code injection and/or XSS

Question 12

What WLAN client device behavior is exploited by an attacker during a hijacking attack?

  1. When the RF signal between a client and an access point is disrupted for more than a few seconds, the client device will attempt to associate to an access point with better signal quality.
  2. When the RF signal between a client and an access point is lost, the client will not seek to reassociate with another access point until the 120 second hold down timer has expired.
  3. After the initial association and 4-way handshake, client stations and access points do not need to perform another 4-way handshake, even if connectivity is lost.
  4. As specified by the Wi-Fi Alliance, clients using Open System authentication must allow direct client-to-client connections, even in an infrastructure BSS.
  5. Client drivers scan for and connect to access points in the 2.4 GHz band before scanning the 5 GHz band.

Question 13

What software and hardware tools are used together to hijack a wireless station from the authorized wireless network onto an unauthorized wireless network? (Choose 2)

  1. RF jamming device and a wireless radio card
  2. A low-gain patch antenna and terminal emulation software
  3. A wireless workgroup bridge and a protocol analyzer
  4. DHCP server software and access point software
  5. MAC spoofing software and MAC DoS software

Question 14

Given: Many computer users connect to the Internet at airports, which often have 802.11n access points with a captive portal for authentication. While using an airport hot-spot with this security solution, to what type of wireless attack is a user susceptible? (Choose 2)

  1. Man-in-the-Middle
  2. Wi-Fi phishing
  3. Management interface exploits
  4. UDP port redirection
  5. IGMP snooping

Question 15

Given: During 802.1X/LEAP authentication, the username is passed across the wireless medium in clear text. From a security perspective, why is this significant?

  1. The username is needed for Personal Access Credential (PAC) and X.509 certificate validation.
  2. The username is an input to the LEAP challenge/response hash that is exploited, so the username must be known to conduct authentication cracking.
  3. 4-Way Handshake nonces are based on the username in WPA and WPA2 authentication.
  4. The username can be looked up in a dictionary file that lists common username/password combinations.
