What is the inverse-square rule as it relates to RF attenuation of a wifi signal?
Doubling the distance decreases signal strength by a factor of four.
Doubling the distance increases signal strength by a factor of four.
Quadrupling the distance decreases signal strength by a factor of two.
Quadrupling the distance increases signal strength by a factor of two.
Which of the following is a measure of wireless performance?
signal to noise ratio (SNR)
number of connected hosts
multiplexor channel bandwidth
hop metric
AP1 is on 2.4 GHz channel 1.
AP2 is also on 2.4 GHz channel 1.
The two wireless APs are adjacent to each other and have overlapping coverage areas.This is called:
co-channel interference (CCI)
adjacent channel interference (ACI)
covalent bonding interference (CBI)
signal-to-noise interference (SNI)
AP1 is on 2.4 GHz channel 1.
AP2 is on 2.4 GHz channel 3.
The two wireless APs are adjacent to each other and have overlapping coverage areas.This is called:
co-channel interference (CCI)
adjacent channel interference (ACI)
covalent bonding interference (CBI)
signal-to-noise interference (SNI)
A wifi client keeps switching back and forth between two APs, causing a degradation of service. This is known as a
flapping client
sticky client
inconsistent service area
RF modulation error
Configuring a wireless AP's 2.4 GHz transmit power lower than its 5 GHz transmit power, and reducing the frequency of 2.4 GHz beacon messages will result in newer devices connecting to the AP using the 5GHz band and older devices (capable of only 2.4 GHz wifi) connecting to the 2.4 GHz channel.
This is called:
band steering
channel separation
channel steering
overlap avoidance
A client is having trouble connecting to the wireless network. SSID broadcast is disabled on the network. The network is dual-band and multi-mode.
What client configuration should be checked?
the SSID for the network
which 2.4 GHz channel the client is using
which 5 GHz channel the client is using
A client is having trouble connecting to the wireless network. SSID broadcast is disabled on the network. The network is dual-band and multi-mode.
What client configuration should be checked?
the password for the network
which 2.4 GHz channel the client is using
which 5 GHz channel the client is using
A client associates with a wireless AP but cannot pass traffic. A check of its IP configuration reveals its IP address is 169.254.64.217.
What is causing the communication problem?
DHCP failure
flapping client
sticky client
DNS failure
Your company's internal network is the 172.16.0.0/24 network.
A client associates with a wireless AP and is assigned the DHCP-assigned IPv4 address 192.168.67.67.
What is likely occurring on this network?
rogue DHCP server
DHCP failure
DHCP exhaustion
DHCP poisoning
