XYZ Company has decided to install an 802.11 WLAN system that will support 1000 wireless users, but they are concerned about network security.
XYZ is interested in deploying standardized security features. In addition to WPA2-Enterprise with PEAP and role-based access control, XYZ would like to support management frame protection as well as a fast secure roaming protocol for future mobile handsets.
As XYZ Company selects a product to deploy, what two IEEE amendments, which are included in 802.11-2012, should be supported to provide the management frame protection and fast secure roaming security features? (Choose 2)
- A . 802.11j
- B . 802.11p
- C . 802.11r
- D . 802.11u
- E . 802.11w
- F . 802.11z
Which one of the following is not a factor considered when calculating the Link Budget for an outdoor point-to-point WLAN bridge link?
- A . Operating frequency
- B . MU-MIMO capabilities of the bridges
- C . Receive antenna gain
- D . Transmit power
Which behavior can be described as an RF signal encountering a chain link fence, causing the signal to bounce into multiple directions?
- A . Diffraction
- B . Scatter
- C . Reflection
- D . Refraction
- E . Multiplexing
What signal characteristics are common in spread spectrum signaling methods? (Choose two.)
- A . Narrow bandwidth
- B . Low power
- C . High power
- D . Wide bandwidth
What are some operational modes in which an AP radio may be configured? (Choose all that apply.)
- A . Scanner
- B . Root
- C . Bridge
- D . Mesh
- E . Repeater
MIMO radios use which mechanisms for transmit diversity? (Choose all that apply.)
- A . Maximum ratio combining (MRC)
- B . Spatial multiplexing (SM)
- C . Space-time block coding (STBC)
- D . Cyclic shift diversity (CSD)
- E . Multiple traffic ID block acknowledgment (MTBA)
A wireless bridge is configured to transmit at 100 mW. The antenna cable and connectors produce a 3 dB loss and are connected to a 16 dBi antenna.
What is the EIRP?
- A . 20 mW
- B . 30 dBm
- C . 2,000 mW
- D . 36 dBm
- E . 8 W
What is an advantage of using WPA2-Personal instead of WEP-128 as a security solution for 802.11 networks?
- A . WPA2-Personal uses 802.1X/EAP for authentication, and WEP-128 uses preshared keys.
- B . WPA2-Personal is based on IEEE 802.11 industry standards, but WEP is not.
- C . WPA2-Personal uses CCMP for encryption, and WEP-128 uses TKIP for encryption.
- D . WPA2-Personal uses dynamic encryption keys, and WEP-128 uses static keys.
- E . WPA2-Personal requires complex 64-character hex keys, whereas WEP-128 requires weak 26-character hex keys.
The 802.11 protocol specifies a fundamental channel access method that is required for all stations and is used in all IBSS and BSS networks.
What is this fundamental channel access method called?
- A . DCF
- B . PCF
- C . HCF
- D . EDCAF
- E . HCCA
- F . PCF/CA
Which of these 802.11 technologies can operate in the 2.4 GHz frequency band? (Choose all that apply.)
- A . 802.11a (OFDM radios)
- B . 802.11b (HR-DSSS radios)
- C . 802.11g (ERP radios)
- D . 802.11n (HT radios)
- E . 802.11ac (VHT radios)
- F . 802.11ax (HE radios)
