- A802.11g
- B802.11n
- C802.11ac
- D802.11ad
2Which two roles are typically performed by a wireless router that is used in a home or small business? (Choose two.)
- Arepeater
- Baccess point
- CWLAN controller
- DEthernet switch
- ERADIUS authentication server
3Which feature of 802.11n wireless access points allows them to transmit data at faster speeds than previous versions of 802.11 Wi-Fi standards did?
- ASPS
- BWPS
- CMIMO
- DMITM
4A supervisor needs wireless access in the construction office during the construction of a new building. The construction office is in the new building and directly across the road from headquarters. What could be used to satisfy this requirement of needing a narrow area of coverage?
- Amultiple MIMO antennas
- Bomnidirectional
- Crubber duck
- DYagi
5Which type of wireless topology is created when two or more Basic Service Sets are interconnected by Ethernet?
- AIBISS
- BBSS
- CWiFi Direct
- DESS
- Ead hoc WLAN
6Which statement defines the control frame operation between two stations?
- AA station sends an RTS frame as the first step in a three-way handshake that is required before sending data frames.
- BA station responds to an RTS frame with an ACK frame, thus providing permission for the requesting station to send a data frame.
- CIf the sending station does not receive an ACK frame within a predetermined period of time, the sending station will drop the connection.
- DAfter receiving a data frame, the receiving station will send an ACK frame to the sending station if no errors are found.
7A student uses a laptop to upload an assignment to a file server. Which wireless frame type did the laptop send to locate and associate with the campus access point?
- Abeacon frame
- Bcontrol frame
- Cdata frame
- Dmanagement frame
8During which stage of establishing connectivity between a WLAN client and an AP does the client learn the MAC address of the AP?
- Adiscovery
- Bprobing
- Cassociation
- Dencryption
- Eauthentication
9For which discovery mode will an AP generate the most traffic on a WLAN?
- Apassive mode
- Bopen mode
- Cmixed mode
- Dactive mode
10What is the purpose of the Distributed Coordination Function in an IEEE 802.11 WLAN environment?
- AIt allows a client to detect whether or not a channel is clear prior to transmission.
- BIt is used in a full-duplex environment to detect collisions.
- CIt is used to send data over a half-duplex connection.
- DIt allows the client to change transmission channels.
11What is an advantage of SSID cloaking?
- AIt provides free Internet access in public locations where knowing the SSID is of no concern.
- BClients will have to manually identify the SSID to connect to the network.
- CSSIDs are very difficult to discover because APs do not broadcast them.
- DIt is the best way to secure a wireless network.
12If three 802.11b access points need to be deployed in close proximity, which three frequency channels should be used? (Choose three.)
- A1

- C802.11g
- D802.11n
- E802.11ac
14An employee connects wirelessly to the company network using a cell phone. The employee then configures the cell phone to act as a wireless access point that will allow new employees to connect to the company network. Which type of security threat best describes this situation?
- Acracking
- Bdenial of service
- Crogue access point
- Dspoofing
15Which security mode is the least secure choice when a home wireless router is configured?
- AWPA
- BWPA2
- CWEP
- DWPA2-Personal
16Which parameter is commonly used to identify a wireless network name when a home wireless AP is being configured?
- Aad hoc
- BBESS
- CESS
- DSSID
17A company has recently implemented an 802.11n wireless network. Some users are complaining that the wireless network is too slow. Which solution is the best method to enhance the performance of the wireless network?
- AReplace the wireless NICs on the computers that are experiencing slow connections.
- BSplit the traffic between the 2.4 GHz and 5 GHz frequency bands.
- CDisable DHCP on the access point and assign static addresses to the wireless clients.
- DUpgrade the firmware on the wireless access point.
