300-425 Question 16
Single answerA retail organization has a distributed branch network with each branch configured as a separate FlexConnect group. Users often roam between branches, and the network administrator has noticed connectivity disruptions during roaming events. What should the administrator do to ensure seamless roaming between branches?
- A
Configure all branches to use the same VLAN-to-SSID mapping.
- B
Enable central authentication for all FlexConnect groups.
- C
Merge the branches into a single FlexConnect group.
- D
Enable Opportunistic Key Caching (OKC) for seamless key management.
Show answer and explanation
Correct answer: C
Explanation
When APs are placed in different FlexConnect groups, client session data is not shared between groups. By merging the branches into a single FlexConnect group, the APs can share session and authentication data, enabling seamless roaming for users moving between branches. Other options either address configuration consistency or optimize roaming within a single group but do not solve inter-group roaming disruptions.
- A. Incorrect.
Configuring the same VLAN-to-SSID mapping ensures consistent configurations but does not address roaming disruptions across FlexConnect groups.
- B. Incorrect.
Enabling central authentication ensures authentication is performed at the central site, but it may increase latency and does not solve the roaming issue between FlexConnect groups.
- C. Correct.
Merging branches into a single FlexConnect group allows for seamless roaming as the APs share the same group and can synchronize client data, including authentication and session information.
- D. Incorrect.
Enabling Opportunistic Key Caching (OKC) can improve roaming within a single FlexConnect group but does not address roaming between different FlexConnect groups.
