2.3 Given a scenario, select and configure wireless devices and technologies.
Objective 2.3 sits in Network Implementation, which carries 20% of the Network+ exam. The questions below are original, written from the official objective title above, and each explanation cites the CompTIA page it rests on.

A worked example
Shown solved, with the whole explanation open: this is what every question here carries.
A cafe wants guest Wi-Fi with no passphrase but encrypted air traffic, while older handsets that lack the feature still connect. Why does this need two interface configurations?
Correct.
Concept
Opportunistic encryption protects an open network without a shared secret, but a beacon advertises one security posture at a time. Supporting devices that predate the feature therefore means running a second network rather than adding a fallback to the first.
Why C
Transition mode publishes a visible unencrypted network for older devices and a hidden encrypted one, and the visible beacon points capable clients at the hidden network. Two interface configurations are what make that pair of advertisements possible.

Now you: objective 2.3 questions
No account needed. The explanation opens when you answer.
Sample question 1 of 3
Which mechanism lets a wireless client ask its current access point for a list of nearby access points?
Sample question 2 of 3
A laptop sits at -85 dBm on an access point whose steering settings are all at their defaults, and stays there for 15 seconds. What does the access point do next?
Sample question 3 of 3
A corporate WLAN authenticates users with 802.1X against a RADIUS server. Where is the outcome of a client's EAP exchange actually decided?
