Question 420
A central services VLAN is on the approved trunk but a new access port uses a mismatched untagged VLAN. Which result would best establish that the correction succeeded?
Explanation
Correct Answer
This is an operational test of the required outcome rather than merely proof a setting exists. It checks that the endpoint is placed into a different broadcast domain than the required service no longer prevents the service.
Incorrect Answers
This result may validate another network change, but it does not demonstrate recovery from the fault here: the endpoint is placed into a different broadcast domain than the required service.
That explanation does not distinguish this option. “The handset obtains its voice-subnet lease and user data traffic stays in the data VLAN” is an alternative action, but it does not by itself establish the outcome required in this case.
That explanation does not distinguish this option. “The AP discovers the correct controller and establishes its expected management session” is an alternative action, but it does not by itself establish the outcome required in this case.
