  A. 5 dBi patch
  B. 13.5 dBi Yagi
  C. 2.2 dBi omni
  D. 21 dBi parabolic

• Question 244:

  Which spread spectrum technique uses 11-bit chips to transmit 1 bit of data over a 22-MHz channel?

  A. DSSS
  B. FHSS
  C. OFDM
  D. MIMO
  E. CCK
  A. DSSS

  ---

  For every 0 or 1 you want to send, DSSS generates a code representing that 0 or that 1. This code, also called symbol or chip, can be a sequence of up to 11 bits (this is called the Barker 11 code), and these 11 bits are sent in parallel over the 22 MHz channel. You can lose up to nine of these 11 bits due to interferences and still understand whether the code sent was supposed to represent a 0 or a 1.

• Question 245:

  Which of the following are three functions of Cisco RRM? (Choose three.)

  A. TPC
  B. intercontroller roaming
  C. dynamic channel assignment
  D. intracontroller roaming
  E. coverage hole detection
  A. TPC
  C. dynamic channel assignment
  E. coverage hole detection

  ---

  RRM can periodically reconfigure the 802.11 RF network for best efficiency. To do this, RRM performs these functions: Radio resource monitoring Transmit power control Dynamic channel assignment Coverage hole detection and correction http://www.cisco.com/c/en/us/td/docs/wireless/controller/7-0MR1/configuration/guide/wlc_cg70MR1/cg_rrm.pdf

  B. config t interface BVI1 ip address 10.0.0.24 255.255.255.224 exit ip default-gateway 10.0.0.1
  C. config t interface FastEthernet1 ip address 10.0.0.24 255.255.255.224 exit ip default-gateway 10.0.0.1
  D. config t interface Dot11Radio0 ip address 10.0.0.24 255.255.255.224 exit ip default-gateway 10.0.0.1
  E. config t interface FastEthernet1 ip address 10.0.0.24 255.255.255.192 exit ip default-gateway 10.0.0.1
  F. config t interface Dot11Radio0 ip address 10.0.0.24 255.255.255.192 exit ip default-gateway 10.0.0.1
  B. config t interface BVI1 ip address 10.0.0.24 255.255.255.224 exit ip default-gateway 10.0.0.1
