Objective 2.9200-301

2.9 Interpret the wireless LAN GUI configuration for client connectivity, such as WLAN creation, security settings, QoS profiles, and advanced settings.

Objective 2.9 sits in Network Access, 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.

2-9Network AccessModerate

A WLAN profile has the option to hide the network name switched on. A visitor with a correctly configured laptop still joins, while a colleague browsing available networks cannot find it.

The controller rejects clients that scan activelyActive scanning is how the configured client found the network, so it is not being rejected.
The visitor's laptop is on a different radio bandA band mismatch would stop the visitor joining too, and the visitor is connected.
Beacons omit the name and broadcast probes go unansweredCorrect · your answerCorrect. The name is absent from beacons and broadcast probes get no reply.
The name is only advertised to authenticated clientsAdvertising is a radio behaviour that happens before any client has authenticated.

Correct.

Concept

A radio announces itself in two ways: unsolicited announcements and answers to a client asking what is nearby. Suppressing the name affects both, which changes who can discover the network but not who can join it.

Why C

With the option set, the access point leaves the name out of its beacons and ignores probe requests that do not name a network. A client configured with the exact name still asks for it directly and associates as normal.

No account needed. The explanation opens when you answer.

Sample question 1 of 3

2-9Network AccessModerate

A wireless access list holds a rule accepting a laptop's address, and below it a rule rejecting the whole address range that laptop falls in. The laptop connects.

Sample question 2 of 3

2-9Network AccessModerate

A guest WLAN has to land in VLAN 90 on the wired side while the staff WLAN stays in VLAN 10, both served by the same access points. Where is that set?

Sample question 3 of 3

2-9Network AccessHard

Access points in a warehouse change channel by themselves overnight, and a survey done last month no longer matches. The configuration leaves the frequency field empty.

That’s 3 of the full CCNA bank.
