Question 890
The WLAN team at a large university has addressed this issue: An AP upgrade introduces a feature that is configured centrally but not supported on some old AP firmware at the site. Which measurable observation would MOST convincingly demonstrate successful remediation?
Explanation
Correct Answer
Only compatible APs consume the feature and each retained legacy AP remains serviceable. This directly checks the outcome of the chosen remediation and confirms the problem was not merely hidden. The diagnostic issue was: cloud configuration objects do not eliminate device firmware capability constraints.
Incorrect Answers
The client's data packets traverse the designated security gateway with proper VLAN policy. This would demonstrate a different scenario was fixed—a corporate SSID is configured for local bridging even though users must traverse a central security enforcement zone—but does not validate recovery from an AP upgrade introduces a feature that is configured centrally but not supported on some old AP firmware at the site.
Guest traffic follows the intended isolated Eth1 path and management remains on the approved interface. This would demonstrate a different scenario was fixed—an AP's second Ethernet port is configured for WLAN breakout but connects to the same unrestricted network as its management link—but does not validate recovery from an AP upgrade introduces a feature that is configured centrally but not supported on some old AP firmware at the site.
The WLAN advertises on only the permitted sites after synchronization. This would demonstrate a different scenario was fixed—a branch user WLAN is accidentally disabled by a site override that conflicts with an otherwise valid organization-wide template—but does not validate recovery from an AP upgrade introduces a feature that is configured centrally but not supported on some old AP firmware at the site.
