• Question 304:

  Refer to the exhibit.

  

  A customer has set up an autonomous access point with a single broadcast SSID on the 2.4-GHz radio and requested that an engineer add an additional SSID to the 2.4-GHz radio. Given the output, what should be configured to implement the new SSID?

• Question 305:

  A customer wants to implement a policy on a guest WLAN, in which clients must accept the company wireless policy and enter an email address to access the guest network. The company does not have access to RADIUS servers and wants the WLAN to use open Layer 2 security. Which Layer 3 security web policy must be enabled to meet these criteria?

  A. authentication
  B. web authorization on MAC filter failure
  C. conditional web redirect
  D. web pass-through
  D. web pass-through

• Question 306:

  What is the maximum number of lightweight APs that can be supported from a single Cisco WCS Navigator management console with Cisco WCS and Cisco WLC running version 7.0 code?

  A. 10,000
  B. 20,000
  C. 25,000
  D. 30,000
  E. 60,000
  D. 30,000

  ---

  The Cisco WCS Navigator supports partitioning of the unified wireless network at the management level. It supports up to 20 Cisco WCS management platforms with manageability of up to 30,000 Cisco Aironet lightweight access points from a single management console. It runs on a server platform with an embedded database.

• Question 307:

  

  Refer to the exhibit. The site in this AirMagnet Survey heat map is ready for which level of service?

  A. voice
  B. data
  C. location
  D. RFID
  B. data

• Question 308:

  Which signal strength reading indicates that the engineer is closest to the access point?

  A. -43 dBm
  B. -67 dBm
  C. -87 dBm
  D. -100 dBm
  A. -43 dBm

• Question 309:

  Which description best describes upfade in a multipath environment?

  A. In this situation, multiple signal paths are not sent at exactly the same time. The receiver receives a positive crest on the primary signal and a negative crest on the secondary signal.
  B. In this situation, the multiple signal paths are distorted and difficult to understand.
  C. In this situation, the multiple signal paths are weaker than they should be because the signals are out of phase with each other.
  D. In this situation, the signal is stronger than it should be because multiple signal paths are received twice at exactly the same time, which results in the multiple signals being in-phase.
  D. In this situation, the signal is stronger than it should be because multiple signal paths are received twice at exactly the same time, which results in the multiple signals being in-phase.

  ---

  If a signal is received twice at exactly the same time, the secondary wave adds its power to the primary wave, so the receiver gets twice the positive energy (positive crest) at the same instant, then twice the negative energy (negative crest) at the same instant. The result is that both waves add up to twice the amplitude (energy) of a single wave, and both signals are said to be in phase (both signals are said to have an angle of 0 degrees). This rare condition is called upfade. If the second signal negative energy (negative crest) reaches the receiver just when the first signal positive energy (positive crest) also reaches the receiver, both signals can cancel each other, resulting in no signal at all (this is the principle used in noise cancellation headsets).
