Objective 1.11
200-301Describe wireless principles.
Objective 1.11 sits in Network Fundamentals, which carries 20% of the CCNA exam. The questions below are original, written from the official objective title above, and each explanation cites the Cisco page it rests on.

A worked example
Shown solved, with the whole explanation open: this is what every question here carries.
After an engineer sets the 802.11b/g 12 Mbps data rate to Mandatory, a fleet of older handheld scanners stops associating. What does that setting do?
Correct.
Checked against cisco.com, August 2026Concept
A station can only join a cell whose required transmission rates it can all meet. Marking a rate as required raises the floor for association and quietly excludes any radio built before that rate existed, so it is a capacity decision paid for in coverage.
Why A
A rate marked Mandatory is one a station has to support before the controller will let it associate, and at least one rate always has to carry that marking. The old scanners top out below 12 Mbps, so raising the floor to that rate removed their only path onto the network.

Cisco: Radio Bands, checked August 2026Mandatory —Clients must support this data rate in order to associate to an access point on the controller. At least one data rate must be mandatory.
Now you: objective 1.11 questions
No account needed. The explanation opens when you answer.
Sample question 1 of 2
A controller report for one floor shows the Noise measurement climbing week on week while Interference stays flat. What kind of source is being counted?
Sample question 2 of 2
A wireless controller pushes a profile that sets the radio band, frequency, transmit power and width for every access point. Which configuration object carries those?
That’s 2 of the full CCNA bank.
