Review 116 CWSP-205 practice questions with answer explanations and community insights.

Question 1

Given: John Smith uses a coffee shop's Internet hot-spot (no authentication or encryption) to transfer funds between his checking and savings accounts at his bank's website. The banks website uses the HTTPS protocol to protect sensitive account information. While John was using the hot-spot, a hacker was able to obtain Johns bank account user ID and password and exploit this information. What likely scenario could have allowed the hacker to obtain Johns bank account user ID and password?

  1. John's bank is using an expired X.509 certificate on their web server. The certificate is on John's Certificate Revocation List (CRL), causing the user ID and password to be sent unencrypted.
  2. John uses the same username and password for banking that he does for email. John used a POP3 email client at the wireless hot-spot to check his email, and the user ID and password were not encrypted.
  3. John accessed his corporate network with his IPSec VPN software at the wireless hot-spot. An IPSec VPN only encrypts data, so the user ID and password were sent in clear text. John uses the same username and password for banking that he does for his IPSec VPN software.
  4. The bank’s web server is using an X.509 certificate that is not signed by a root CA, causing the user ID and password to be sent unencrypted.
  5. Before connecting to the bank’s website, John’s association to the AP was hijacked. The attacker intercepted the HTTPS public encryption key from the bank’s

Question 2

You are configuring seven APs to prevent common security attacks. The APs are to be installed in a small business and to reduce costs, the company decided to install all consumer-grade wireless routers. The wireless routers will connect to a switch, which connects directly to the Internet connection providing 50 Mbps of Internet bandwidth that will be shared among 53 wireless clients and 17 wired clients. To ensure the wireless network is as secure as possible from common attacks, what security measure can you implement given only the hardware referenced?

  1. WPA-Enterprise
  2. 802.1X/EAP-PEAP
  3. WPA2-Enterprise
  4. WPA2-Personal

Question 3

A WLAN is implemented using WPA-Personal and MAC filtering. To what common wireless network attacks is this network potentially vulnerable? (Choose 3)

  1. Offline dictionary attacks
  2. MAC Spoofing
  3. ASLEAP
  4. DoS

Question 4

An attack is under way on the network. The attack is preventing users from accessing resources required for business operations, but the attacker has not gained access to any files or data. What kind of attack is described?

  1. Man-in-the-middle
  2. Hijacking
  3. ASLEAP
  4. DoS

Question 5

Given: WLAN attacks are typically conducted by hackers to exploit a specific vulnerability within a network. What statement correctly pairs the type of WLAN attack with the exploited vulnerability? (Choose 3)

  1. Management interface exploit attacks are attacks that use social engineering to gain credentials from managers.
  2. Zero-day attacks are always authentication or encryption cracking attacks.
  3. RF DoS attacks prevent successful wireless communication on a specific frequency or frequency range.
  4. Hijacking attacks interrupt a user’s legitimate connection and introduce a new connection with an evil twin AP.
  5. Social engineering attacks are performed to collect sensitive information from unsuspecting users
  6. Association flood attacks are Layer 3 DoS attacks performed against authenticated client stations
