NO.1 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.
Answer: C

NO.2 A controller is connected to a Cisco Catalyst switch. The switch port configuration looks like
this:
interface GigabitEthernet 1 / 0/10
switchport
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
Answer: A

NO.3 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.
Answer: D

NO.4 The IEEE 802.11n standard provides 40-MHz channels, improved MAC efficiency, and MIMO.

C. maximal ratio combining
D. packet aggregation
E. spatial multiplexing
F. transmit beam forming
Answer: C,E,F

NO.5 Which two items are needed to discover the IP address of a new Cisco Aironet 1260
autonomous AP that just finished booting? (Choose two.)
A. username = "cisco" and password = "cisco"
B. username = "Admin" and password = "Cisco"
C. username=Cisco and password=Cisco
D. show int vlan1
E. show int bvi1
F. show int gigabitethernet0
G. show int radio0-802.11n
H. show int radio1-802.11n
Answer: C,E

NO.6 Which two factors must be considered when evaluating an RF interferer for severity? (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.
Answer: B,C
