What device is often used to manage several APs in a centralized manner? - ANSWER - Controller A controller is often installed to manage several APs from a centralized location. In fact, controllers can often manage thousands of APs.
What is the term most commonly used to describe the phenomenon caused when an RF signal strikes an object it is unable to penetrate but is not diffracted by the object either? - ANSWER - Reflection When an RF signal strikes an object and is unable to penetrate the object and is not diffracted by the object, that phenomenon is called reflection.
How many 20 MHz channels are available in the 5 GHz band? -
ANSWER - 25
25 channels are available as of 2017. More frequency space may be opened in the future.
When client devices are communicating with each other without the use of an access point, in which mode of operation are the functioning? - ANSWER - Ad Hoc Mode Ad Hoc Mode allows stations to communicate with each other without the use of an access point. It is also a security concern. 1 / 4

pg. 2 Increasingly, organizations want to manage guest access beyond the use of a single shared key for guest use. What has become the most often used means of accomplishing this goal? - ANSWER - A Guest Management System A Guest Management System can allow unique credentials per user or per device while using a single SSID for guests.
What is the main reason networks allow guest wireless access? - ANSWER - To allow guests Internet access without exposing the private network Guests expect wireless network access. Allowing them to connect to their offices and the Internet is good business. However, their access should be configures so as not to touch the private network. Creating a separate network using another SSID is a common security measure.Their traffic is often on another VLAN or physical wired network.
Why do clients take some time to roam from one AP to another even when the APs are part of the same Extended Service Set (ESS)? - ANSWER - They must reassociate and authenticate properly to the new AP Even when two APs are part of the same ESS, they are separate networks from a Basic Service Set (BSS) perspective. The clients are connected to one BSS and must move to another BSS to roam within an ESS. The client is fully associated with only on BSS at a time.Therefore, some time is required to move from one BSS to the next.
Which one of the following is often an issue that must be addressed in hospital environments? - ANSWER - Walls that block RF 2 / 4

pg. 3 X-Ray rooms often have lead-lined walls that block RF. To address this, if WLAN coverage is required in the X-Ray room, an AP may be installed within the room. Internet uplinks for mobile transportation are more commonly seen in planes, trains and other public transportation systems. PCI DSS is a constraint in retail where credit and debit cards are accepted. Frequent large trucks making deliveries is more common in industrial and warehousing deployments.
What is required in many regulatory domains for the middle range of 5 GHz channels? - ANSWER - DFS Dynamic Frequency Selection (DFS) is required in several 5 GHz channels in many regulatory domains. DFS allows for the detection of radar signals and the moving from the detected signal channel to another.
Which Wi-Fi device can only connect in the 5 GHz band using the specified options? - ANSWER - A laptop using an 802.11ac radio 802.11ac only operates in the 5 GHz band. Any device using only an 802.11ac radio will only be able to connect in the 5 GHz band.
What is the main advantage of using a grid antenna vs. using a dish antenna in a point-to -point WLAN bridged connection? - ANSWER - Reduced wind effect Wind can move an antenna reducing the quality of the connection or even causing the connection to fail completely. Grid antennas are less susceptible to the effects of wind, since they aloe the wind to blow through them rather than being moved by the wind.

pg. 4 When deploying a single access point for a Small Office Home Office (SOHO) environment for use by fewer than five client devices, what is the most common thing a site survey would be used to determine? - ANSWER - Channels in use nearby It is expected to have neighboring devices in most every deployment. In a SOHO deployment as described above, there is only one access point to be deployed and in a small space. Its placement is not as large a matter as in a multi access point enterprise solution. Channel use is an important consideration. The largest source of trouble for a WLAN is neighboring devices. Selecting the least populated channel for use is the most common thing a SOHO site survey is used to determine.
Your WLAN devices are powered using PoE switches. When you install a new PoE enabled access point it will not power up when connected to the PoE switch that is powering other APs. What is the most likely cause of this problem? - ANSWER - The access point is connected to a non- PoE port on the switch Many PoE switches have both power providing and non-power providing ports. When expecting to power an access point using PoE, make sure that the AP is connected to a power providing port. The port may be configurable to either provide PoE power or not. The switch is not likely powered off because it is powering other APs. Any properly wired CAT 5 or CAT 6 Ethernet cable should allow for PoE power. Most APs do not have a power switch on them. When power is injected, either through PoE or AC wall power, the AP powers up.
802.1X authentication is implemented when using which type of WLAN security? - ANSWER - WPA/WPA2-Enterprise
