Q32. Given: ABC Company is implementing a secure 802.11 WLAN at their headquarters (HQ) building in New York and at each of the 10 small, remote branch offices around the United States. 802.1X/EAP is ABC’s preferred security solution, where possible. All access points (at the HQ building and all branch offices) connect to a single WLAN controller located at HQ. Each branch office has only a single AP and minimal IT resources.
What security best practices should be followed in this deployment scenario?

Q33. In the basic 4-way handshake used in secure 802.11 networks, what is the purpose of the ANonce and SNonce? (Choose 2)

Q34. 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)

Q35. Given: An 802.1X/EAP implementation includes an Active Directory domain controller running Windows Server 2012 and an AP from a major vendor. A Linux server is running RADIUS and it queries the domain controller for user credentials. A Windows client is accessing the network.
What device functions as the EAP Supplicant?

Q36. Given: You have implemented strong authentication and encryption mechanisms for your enterprise 802.11 WLAN using 802.1X/EAP with AES-CCMP.
For users connecting within the headquarters office, what other security solution will provide continuous monitoring of both clients and APs with 802.11-specific tracking?

Q37. When TKIP is selected as the pairwise cipher suite, what frame types may be protected with data confidentiality? (Choose 2)

Q38. What 802.11 WLAN security problem is directly addressed by mutual authentication?

Q39. Given: A WLAN protocol analyzer trace reveals the following sequence of frames (excluding the ACK frames):
1) 802.11 Probe Req and 802.11 Probe Rsp
2) 802.11 Auth and then another 802.11 Auth
3) 802.11 Assoc Req and 802.11 Assoc Rsp
4) EAPOL-KEY
5) EAPOL-KEY
6) EAPOL-KEY
7) EAPOL-KEY
What security mechanism is being used on the WLAN?

Q40. What protocols allow a network administrator to securely manage the configuration of WLAN controllers and access points? (Choose 2)

Q41. Given: In XYZ’s small business, two autonomous 802.11ac APs and 12 client devices are in use with WPA2- Personal.
What statement about the WLAN security of this company is true?

Q42. Given: ABC Company has recently installed a WLAN controller and configured it to support WPA2- Enterprise security. The administrator has configured a security profile on the WLAN controller for each group within the company (Marketing, Sales, and Engineering).
How are authenticated users assigned to groups so that they receive the correct security profile within the WLAN controller?

Q43. Wireless Intrusion Prevention Systems (WIPS) provide what network security services? (Choose 2)

Q44. Given: Your network includes a controller-based WLAN architecture with centralized data forwarding. The AP builds an encrypted tunnel to the WLAN controller. The WLAN controller is uplinked to the network via a trunked 1 Gbps Ethernet port supporting all necessary VLANs for management, control, and client traffic.
What processes can be used to force an authenticated WLAN client’s data traffic into a specific VLAN as it exits the WLAN controller interface onto the wired uplink? (Choose 3)

Q45. What is the purpose of the Pairwise Transient Key (PTK) in IEEE 802.11 Authentication and Key Management?

Q46. 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)

Q47. You are using a utility that takes input and generates random output. For example, you can provide the input of a known word as a secret word and then also provide another known word as salt input. When you process the input it generates a secret code which is a combination of letters and numbers with case sensitivity. For what is the described utility used? (Choose 3)

Q48. While performing a manual scan of your environment using a spectrum analyzer on a laptop computer, you notice a signal in the real time FFT view. The signal is characterized by having peak power centered on channel 11 with an approximate width of 20 MHz at its peak. The signal widens to approximately 40 MHz after it has weakened by about 30 dB.
What kind of signal is displayed in the spectrum analyzer?

Q49. Given: ABC Company is an Internet Service Provider with thousands of customers. ABC’s customers are given login credentials for network access when they become a customer. ABC uses an LDAP server as the central user credential database. ABC is extending their service to existing customers in some public access areas and would like to use their existing database for authentication.
How can ABC Company use their existing user database for wireless user authentication as they implement a large-scale WPA2-Enterprise WLAN security solution?

Q50. As the primary security engineer for a large corporate network, you have been asked to author a new security policy for the wireless network. While most client devices support 802.1X authentication, some legacy devices still only support passphrase/PSK-based security methods.
When writing the 802.11 security policy, what password-related items should be addressed?

Q51. Given: WLAN protocol analyzers can read and record many wireless frame parameters.
What parameter is needed to physically locate rogue APs with a protocol analyzer?

Q52. Which one of the following is a valid reason to avoid the use of EAP-MD5 in production WLANs?

Q53. ABC Company requires the ability to identify and quickly locate rogue devices. ABC has chosen an overlay WIPS solution with sensors that use dipole antennas to perform this task. Use your knowledge of location tracking techniques to answer the question.
In what ways can this 802.11-based WIPS platform determine the location of rogue laptops or APs? (Choose
