A. client MAC address
B. 802.11 authentication
C. IP address assignment
D. 802.11 association
E. successful association
F. authentication method
H. client radio type
Which two statements about the Cisco WLC and AP code upgrade when 7.0 is running are true? (Choose two.)
A. The AP can download and run new code only after a Cisco WLC reboot causes the AP discovery
B. The AP can download new code before the Cisco WLC reboot, but only if the AP is configured the
CLI via SSH.
C. The AP can download new code before Cisco WLC reboot if it is configuring the Cisco WLC directly
using the GUI via HTTP or HTTPS.
D. The Cisco WLC defaults to booting newer code, but it can boot older backup code only from the
E. The Cisco WLC can boot either primary or back code configured from the GUI.
F. The Cisco WLC can download only a single code at a time for reboot.
You are on the phone working with a colleague that is console connected to a lightweight AP that has lost its configuration.
Which three actions are neecessary to allow the AP to connect to a controller? (Choose three.)
A. Configure the AP IP address.
B. Configure the controller name.
C. Configure the controller IP address.
D. Configure the AP hostname.
E. Configure the AP IP default-gateway.
F. Configure the AP username and password.
You have a lightweight AP that has been moved to a new subnet and has become stranded because DNS and DHCP servers are unavailable. The AP cannot connect to the controller.
When connected to the console port, which three minimum parameters must you configure? (Choose three.)
A. AP IP address
B. controller name
C. AP hostname
D. default gateway IP address
E. controller IP address
F. username and password
The IEEE 802.11n standard provides 40-MHz channels, improved MAC efficiency, and MIMO.
Which three elements define the 802.11n implementation of MIMO? (Choose three.)
A. channel bonding
B. dynamic frequency selection
C. maximal ratio combining
D. packet aggregation
E. spatial multiplexing
F. transmit beam forming
Which two statements about WiMAX technology are true? (Choose two.)
A. WiMAX is defined by 802.11i.
B. Typically, fixed WiMAX networks have a higher-gain directional antenna installed near the client.
C. WiMAX is capable of working as a long-range system over several miles.
D. WiMAX works only for licensed frequencies.
Which governing body analyzes the applications and environments in which wireless networks are used?
E. WiFi Alliance
Which description best describes upfade in a multipath environment?
A. In this situation, multiple signal paths are not sent at exactly the same time. The receiver receives a
positive crest on the primary signal and a negative crest on the secondary signal.
B. In this situation, the multiple signal paths are distorted and difficult to understand.
C. In this situation, the multiple signal paths are weaker than they should be because the signals are out
of phase with each other.
D. In this situation, the signal is stronger than it should be because multiple signal paths are received
twice at exactly the same time, which results in the multiple signals being in-phase.
A controller is connected to a Cisco Catalyst switch. The switch port configuration looks like this:
interface GigabitEthernet 1/0/10
switchport trunk encapsulation dot1q
switchport trunk allowed vlan 1,20,30,50
switchport trunk native vlan 20
switchport mode trunk
Which controller CLI command assigns its management interface to the native VLAN interface of the Cisco Catalyst switch?
A. config interface vlan management 0
B. config interface vlan management 1
C. config interface vlan management 20
D. config interface vlan management 30
E. config interface vlan management 50
Which statement about an infrastructure basic service set is true according to IEEE 802.11 specifications?
A. The set also is called an ad hoc network.
B. The BSSID is generated from the first wireless client that starts up in the IBSS.
C. The set enables the use of ESS.
D. No signals are relayed from one client to another client.
