When connecting to a wireless local area network (WLAN), what is the most important
fact about the service set identifier (SSID)? - correct answer That the clients and all
access points (AP) must be configured with matching ssids.
How does a client locate a wireless local area network (WLAN) when performing
passive scanning? - correct answer The client listens for beacons until it hears a beacon
listing the service set identifier (SSID) of the network it expects to join.
Why would a wireless local area network (WLAN) administrator rarely see the
"authenticated" step on the access point (AP)? - correct answer Because clients pass
the authentication stage and immediately proceed into the association stage.
Why is shared key authentication considered a security risk in a wireless local area
network (WLAN)? - correct answer The access point (AP) transmits the challenge text in
the clear and receives the same challenge text encrypted with the wired equivalent

In a segmented wireless local area network (WLAN) that has a different Internet
protocol (IP) address for each segment, which solution allows mobile clients to maintain
their connectivity when roaming into different segments? - correct answer Deploying all
access points (AP) on a single virtual local area network (VLAN) using a flat IP subnet
for all aps so that no change of IP address for roaming clients occurs and all traffic goes
through a central controller.
Which one of the following power management modes populates a traffic indication map
(TIM) in a basic service set (BSS) or extended service set (ESS)? - correct answer
Power save polling (PSP) mode.
