300-430 Question 19
Single answerA retail company has deployed a wireless network using Cisco FlexConnect for their branch locations. Each branch is configured under its own FlexConnect group. A user roams between two APs located in different FlexConnect groups within the same branch. What will happen to the user's session and connectivity?
- A
The user's session will be preserved, and roaming will be seamless because both APs share the same VLAN mapping.
- B
The user's session will be dropped because roaming across FlexConnect groups is not supported.
- C
The user's session will be preserved, but the user will experience a brief disconnection due to reauthentication.
- D
The user's session will only be preserved if the WLAN is configured for central switching.
Show answer and explanation
Correct answer: C
Explanation
When a user roams between APs in different FlexConnect groups, the session is preserved, but the user may experience a brief interruption in connectivity. This is because the roaming process involves reauthentication when moving between FlexConnect groups. Proper WLAN configuration can help mitigate issues, but reauthentication is generally expected in this scenario.
- A. Incorrect.
Incorrect: VLAN mapping being the same does not guarantee seamless roaming when moving between different FlexConnect groups.
- B. Incorrect.
Incorrect: Roaming across FlexConnect groups is supported, but it does require reauthentication, which may cause a brief disconnection.
- C. Correct.
Correct: When a user roams between APs in different FlexConnect groups, the session is preserved but reauthentication occurs, leading to a brief disconnection.
- D. Incorrect.
Incorrect: FlexConnect local switching can still preserve sessions during roaming, provided it is configured properly.
