Answer : C

Given: You are performing a site survey using software that simulates RF behavior in a defined environment. It uses a floor plan and materials information for its calculations.
What kind of site survey is performed using this method?

  • A. Manual
  • B. Active
  • C. Predictive
  • D. Passive

Answer : C

Given: In Single-Channel Architecture (SCA) systems, multiple access points can use the same BSSID. This feature allows for the creation of a network-wide virtual access point that can be applied across multiple physical access points operating on the same channel.
What benefit does this solution offer?

  • A. The virtual AP can be managed using a WIPS platform
  • B. Transmissions travel farther since they are repeated by other APs
  • C. A wider variety of available security mechanisms are available
  • D. Client stations do not have to make roaming decisions

Answer : D

What statement accurately describes an advantage of manual RF site surveys over predictive site surveys?
A. Manual site surveys are useful for locating and identifying sources of RF interference, while predictive site surveys are not capable of this task.
B. Manual site surveys are more efficient than predictive site surveys in large facilities because GPS mapping can be used.
C. Manual site surveys are more accurate than predictive site surveys because they take advantage of complex computer simulations.
D. Manual site surveys allow the site surveyor to create a static RF environment, whereas predictive site surveys are subject to changes in the RF environment.

Answer : A Topic 5, Applications, Support, and Troubleshooting

What symptom would indicate the presence of a hidden node in a Wi-Fi network?

  • B. An increase in antenna diversity
  • C. An increase in signal leakage
  • D. An increase in retransmissions

Answer : D

After your city implemented a municipal Wi-Fi network using 802.11g on channels 1, 6, and
11 near your office, your users have been complaining about poor performance on their
802.11b VoWiFi phones. The best solution for optimizing your 802.11a/g network to support VoWiFi in this scenario is to _____________.

  • A. Configure your VoWiFi phones for unused 2.4 GHz channels.
  • B. Buy new phones that support WPA2-Personal security.
  • C. Upgrade your VoWiFi phones to 802.11g.
  • D. Buy new 5 GHz capable VoWiFi phones.

Answer : D

As an alternative to using leased lines to connect two offices on the same campus, your customer wants to implement a Wi-Fi solution. When asked by your customer, what advantages do you cite regarding use of a Wi-Fi infrastructure instead of a leased line?
(Choose 2)

  • A. Wi-Fi implementations are more reliable than leased lines.
  • B. Wi-Fi implementations have a lower total cost of ownership than leased lines.
  • C. Wi-Fi implementations are not susceptible to outages caused by inclement weather.
  • D. Wi-Fi implementations support larger numbers of simultaneous connections than leased lines.
  • E. Wi-Fi implementations offer more flexibility and easier expansion than leased lines.

Answer : B,E

What is the most likely cause of low throughput on a hotel's guest network?

  • A. The 1.5 Mbps Internet connection is creating a bottleneck for the Wi-Fi users.
  • B. The user's laptop does not have 54 Mbps data rate enabled.
  • C. The strong security methods used with public access networks often cause low throughput.
  • D. The user is too close to the servicing access point.

Answer : A

Which one of the following adjustments can most benefit a high density environment?

  • A. Antennas with more gain
  • B. APs with lower output power
  • C. PoE with more wattage
  • D. Controllers with fewer 802.3 ports

Answer : B

Where is the use of a Wireless Internet Service Provider (WISP) most appropriate?

  • A. Wi-Fi bridging between two or more buildings within a city
  • B. To provide guest access to the Internet in an office building
  • C. As hot-spot connectivity in large airports and conference centers
  • D. Last mile wireless data delivery to homes and businesses

Answer : D

As an RF signal propagates, it reflects off an object. The reflected signal and the signal following a direct path arrive at the receiver at different points in time. What is the term used to describe this RF behavior?

  • A. Antenna Diversity
  • B. Multipath
  • C. Multiple In, Multiple Out (MIMO)
  • D. Channel Reciprocity
  • E. Beamwidth Refraction

Answer : B

Given: A customer has recently purchased an 802.11g access point that accepts multiple external antennas. The customer wants to know if they need to purchase multiple antennas or a single antenna for the AP.
What do you tell them is a benefit of using multiple antennas?

  • A. Additional gain and therefore a larger coverage area
  • B. Additional functionality through enabling of repeater features
  • C. Transmit and receive diversity that addresses multipath problems
  • D. Improved throughput by enabling full-duplex communication

Answer : C

Given: In ABC Company's branch office, there are three 802.11n access points serving 20
Wi-Fi clients for email, web browsing, and occasional file sharing. Some users sit at a picnic table outside the building during lunchtime and have complained that the network is slow and connectivity is intermittent during this period of time.
What is the most likely cause of the slow and intermittent connectivity?

  • A. The users experiencing connectivity problems are using WPA2-Personal, which has shorter range than 802.1X/EAP.
  • B. WLANs require visual line-of-sight, and only those clients that can see an AP through a window can connect.
