  1. A
    Threeor more patch antennas installed in a circular pattern on the same supporting structure
  2. B
    Onehigh-gain omni-directional antenna
  3. C
    Threeor more parabolic dish antennas installed in a circular pattern on the same supporting structure
  4. D
    Threeor more sector array antennas installed in a circular pattern on the same supporting structure
  5. E
    Threeor more Yagi antennas installed in a circular pattern on the same supporting structure

Correct Answer:
D

Question #16
Which of the following statements are true regarding RLDP? (Choose two)
  1. A
    RLDP works only on APs configured in Open Authentication mode.
  2. B
    RLDP only works if the AP is in Monitor Mode.
  3. C
    RLDP will attempt to identify each Rogue AP only once.
  4. D
    RLDP only works if the Rogue AP is connected to a VLAN that is reachable by the WLC.
  5. E
    RLDP only works if the AP is in Local Mode.

Correct Answer:
AD

Question #17
Which of the following statements are not correct about Client Management Frame Protection (MFP)? (Choose 2.)
  1. A
    Client MFP can replace Infrastructure MFP in case only CCXv5 clients are used.
  2. B
    Client MFP encrypts class 3Unicastmanagement frames using the security mechanisms defined by 802.11i.
  3. C
    In order to use Client MFP the client must support CCXv5 and negotiate WPA2 with AES-CCMP or TKIP.
  4. D
    The only supported method to obtain the pre-user MFP encryption keys is EAP authentication.
  5. E
    CCXv5 client and access points must discard broadcast class 3 management frames.

Correct Answer:
AD

Question #18
Corporation XYZ just underwent a third-party security audit. The auditors have required that the corporation implements 802.1x on its wireless network and disable all pre-shared key WLANs as soon as possible. XYZ does not have an internal CA installed to provide server certificates today. However, it wishes to implement an EAP method that requires clients to use server authentication in the future. XYZ also needs an EAP method that will allow both Active Directory user authentication and time-based tokens.
What is the best EAP method for XYZ to implement?
  1. A
    TTLS
  2. B
    PEAP
  3. C
    FAST
  4. D
    TLS

Correct Answer:
C
