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.

this:
interface
GigabitEthernet 1 / 0/10
switchport
switchport trunk encapsulation
dot1q
switchport trunk allowed vlan 1,20,30,50

Answer:
A
NO.8 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
