Question 90
A wireless client can associate to an SSID but never obtains an IPv4 address, while neighboring wired clients obtain DHCP leases. Which immediate engineering change most directly addresses this issue?
Explanation
Correct Answer
The underlying issue is that association success verifies radio access, not correct DHCP transport into the client subnet. This intervention addresses that cause directly. A useful result to confirm is: the client receives correct IP settings through the intended WLAN and VLAN path.
Incorrect Answers
This is suited to a different condition, such as when an office has a high-density 2.4 GHz WLAN where many IoT sensors use old low basic rates, consuming excessive airtime. The reported fault instead arises because association success verifies radio access, not correct DHCP transport into the client subnet.
This is suited to a different condition, such as when a voice WLAN introduces rapid roaming requirements, but the configuration has no support for the client-compatible 802.11r fast transition mechanism. The reported fault instead arises because association success verifies radio access, not correct DHCP transport into the client subnet.
This is suited to a different condition, such as when the campus WLAN's APs transmit at maximum power, creating very large overlapping cells and sticky client behavior. The reported fault instead arises because association success verifies radio access, not correct DHCP transport into the client subnet.
