, A type of wireless network that provides access to the Internet, but not to the internal
network is referred to as guest WiFi network. Setting up a separate network for visitors
(handled by a dedicated access point) protects the internal network against risks related
to unauthorized activities and malware infections.
True
False - ANSWERTrue
In wireless networks, channel overlapping is a situation where multiple channels share
the frequency band causing interference and performance degradation for devices
operating on channels that are too close to each other. A common example of channel
overlapping would be the 2.4 GHz band used in 802.11 networks, where the 2.401 -
2.473 GHz frequency range is used for allocating 11 channels, each taking up a 22-
MHz portion of the spectrum. Setting up a wireless network to operate on a non-
overlapping channel (1, 6, and 11 in this case) allows multiple networks to coexist in the
same area without causing interference.
True
False - ANSWERTrue
In the context of implementing secure network designs, the term "Port security" may
apply to:
Disabling physical ports on a device (e.g., RJ-45 device ports on a router, switch, or
patch panel)
Implementing MAC filtering
Disabling unused logical ports (TCP/UDP)
Implementing Port-based Network Access Control (defined in the IEEE 802.1X
standard)
All of the above - ANSWERAll of the above
A server with private IP address has been set up to handle requests from an outside
(public) network. Which of the solutions listed below would enable this functionality?
Port bonding
Port labeling
Port forwarding
Port mirroring - ANSWERPort forwarding
Port mirroring allows an administrator to inspect traffic passing through a network
switch. On a switch that supports port mirroring, a packet analyzer can be connected to
an empty port and the switch can be configured to pass a copy of the data sent over
one or multiple ports on that switch to the packet sniffer port allowing the administrator
to monitor contents of the traffic passing through the switch.
