  Alarms are color coded as follows: Red --Critical Alarm Orange --Major Alarm Yellow --Minor Alarm The Alarm Summary displays the number of current critical, major, and minor alarms. http://www.cisco.com/c/en/us/td/docs/wireless/wcs/60/configuration/guide/WCS60cg/6_0event.html

• Question 362:

  Which statement describes spread spectrum technology in wireless communications?

  A. Signal is spread across optical pulses.
  B. Signal is spread across variations of amplitudes.
  C. Signal is spread across one frequency.
  D. Signal is spread across a whole band of frequencies.
  D. Signal is spread across a whole band of frequencies.

  ---

  spread-spectrum techniques are methods by which a signal with a particular bandwidth is deliberately spread in the frequency domain, resulting in a signal with a wider bandwidth. Spread spectrum generally makes use of a sequential noise-like signal structure to spread the normally narrowband information signal over a relatively wideband (radio) band of frequencies. http://en.wikipedia.org/wiki/Spread_spectrum

• Question 363:

  About SPLIT MAC design. Drag each description on the left to the appropriate term on the right.

  Select and Place:

  

  

• Question 364:

  An engineer has been noticing the power settings on several of the office APs change from day to day ever since two more APs were installed. After logging into the WLC, the engineer verifies that the power levels on 4 of the 802.11n radios are fluctuating up and down. What is the reason for this?

  A. The controller has the APs in H-REAP mode and are on a Layer 2 connection instead of Layer 3.
  B. The RRM has revealed a bad survey and is attempting to power down some of the radios to make up for it.
  C. The WLC has created temporary coverage holes while stepping through power levels for some of the APs.
  D. Several APs have high levels of overlapping coverage in the same area and the WLC is using RRM to correct the cell sizes AP coverage.
  D. Several APs have high levels of overlapping coverage in the same area and the WLC is using RRM to correct the cell sizes AP coverage.

• Question 365:

  Drag the characteristics on the left that are associated with the specific controller-based AP deployment mode and drop them in the appropriate category on the right.

  Select and Place:

  

  

• Question 366:

  After the initial deployment at a customer site, the master controller mode function was left enabled on the secondary controller after access points were primed and statically configured with primary, secondary, and tertiary controller failover. The guest anchor controller was also deployed in the architecture. The access points reboot after a power failure. Which controller will the access points associate to when the reboot process is completed?

  A. primary controller
  B. secondary controller
  C. tertiary controller
  D. guest anchor controller
  B. secondary controller

• Question 367:

  You are in a coffee shop and you have connected to their wireless hot- spot. Your Windows 7 wireless client shows five green bars with a yellow shield. Which statement about the level of signal strength and the WLAN security that is present is true?

  A. You have excellent signal strength and a secure network connection.
  B. Your wireless client needs a username and password before it can connect to the WLAN.
  C. You have excellent signal strength and the client is waiting for you to enter a username and password.
  D. Your laptop is not receiving a signal.
  E. Your laptop is receiving an excellent signal and the network security is open.
  E. Your laptop is receiving an excellent signal and the network security is open.

  ---

  Five green bars mean that the signal you are receiving is excellent (there are up to 5 bars) and the yellow shield is a warning indication signal that the security settings have been set to open, meaning no authentication is needed.

• Question 368:

  Which two Cisco Unified Wireless Network capabilities use information that is provided by Radio Resource Management neighbor messages in version 7.0 MR1? (Choose two.)

  A. aggressive load balancing
  B. dynamic channel assignment
  C. hybrid remote edge access point
  D. inter-controller mobility (that is, mobility groups)
  E. rogue AP classification
  B. dynamic channel assignment
  E. rogue AP classification

• Question 369:

  Which two principles must be considered when deploying a wireless network through a wooded area? (Choose two.)

  A. absorption
  B. reflection
  C. diffraction
  D. scattering
  E. refraction
  A. absorption
  D. scattering

• Question 370:

  Which two types of encryption does Windows support for WPA2 security for wireless connections? (Choose two.)

  A. AES
  B. DES
  C. PGP
  D. TKIP
  E. WEP
  A. AES
  D. TKIP

  TKIP and AES are two different types of encryption that can be used by a Wi-Fi network. TKIP stands for "Temporal Key Integrity Protocol." It was a stopgap encryption protocol introduced with WPA to replace the very-insecure WEP

  encryption at the time. TKIP is actually quite similar to WEP encryption. TKIP is no longer considered secure, and is now deprecated. In other words, you shouldn't be using it.

  AES stands for "Advanced Encryption Standard." This was a more secure encryption protocol introduced with WPA2, which replaced the interim WPA standard. AES isn't some creaky standard developed specifically for Wi-Fi networks; it's a

  serious worldwide encryption standard that's even been adopted by the US government. For example, when you encrypt a hard drive with TrueCrypt, it can use AES encryption for that. AES is generally considered quite secure, and the main

  weaknesses would be brute-force attacks (prevented by using a strong passphrase) and security weaknesses in other aspects of WPA2.
