  E. 11
  F. 12
  G. 18
  A. 2
  B. 5.5
  E. 11

• Question 65:

  When calculating the link budget for a wireless point-to-point bridge, the engineer notices that one antenna has its gain marked as 2.85 dBd. With a 20-mW access point and 3-dBi loss for the cable, what is the approximate EIRP?

  A. 15 dBm
  B. 18 dBm
  C. 22 dBm
  D. 25 dBm
  A. 15 dBm

• Question 66:

  Which type of basic radiation pattern does a Yagi antenna have?

  A. circular
  B. semicircular
  C. straight line
  D. cone
  D. cone

  ---

  High gain directional antennas: A point to point high gain antenna is a directional antenna that has a focused radiation pattern. The radiation pattern is typically a cone 10 to 30 degrees wide. A yagi and a parabolic dish are examples of high gain directional antennas. http://www.hp.com/rnd/pdfs/antenna_tech_brief.pdf

• Question 67:

  Drag the correct visual description from the left to the matching Windows 7 wireless client description on the right.

  Select and Place:

  

  

• Question 68:

  You have an Apple IOS iPhone4 that is used on your home Wi-Fi network and a personal laptop that is used on your work's enterprise wireless network. At your office, you are unable to see the enterprise wireless network on your iPhone4. What is the most likely cause of this issue?

  A. WPA2 CPU intensive encryption is not supported on the client.
  B. WPA2 must be enabled on the client.
  C. A new profile must be created on the client.
  D. Wi-Fi must be enabled on the client.
  E. The enterprise is 2.4 GHz only.
  F. The enterprise is 5 GHz only.
  G. The RF channel must be adjusted on the client.
  F. The enterprise is 5 GHz only.

  ---

  The iPhone4 only supports 2.4 Ghz wireless. 5 Ghz wireless support was added with the iPhone5.

• Question 69:

  When planning for VoWLAN applications, what must the overlap be between the cells?

  A. no overlap
  B. 15 to 20 percent
  C. 30 to 40 percent
  D. 25 to 30 percent
  B. 15 to 20 percent

  ---

  The optimal VoWLAN network requires overlaps of 20 percent (2.4 GHz), and approximately 15 to 20 percent (5 GHz), where a WLAN Data design may use an AP cell overlap of 5 to 10 percent.

  B. The wireless client must use an EAP authentication method with the infrastructure authenticator.
  C. The client's password must be the same on both APs.
  D. The next cell should provide the same SSID as the client's current cell.
  E. The clients need static IP addresses.
  D. The next cell should provide the same SSID as the client's current cell.
