300-425 · Question #29

Which statement about creating a mobility group is true, excluding mobility anchors?

The correct answer is A. Each WLC must use the same mobility name and be defined as a peer in each other's static. WLC mobility groups require all members to share the same mobility group name and be manually configured as static peers on each controller.

Why each option

WLC mobility groups require all members to share the same mobility group name and be manually configured as static peers on each controller.

AEach WLC must use the same mobility name and be defined as a peer in each other's staticCorrect

For inter-controller roaming to function, every WLC in a mobility group must be configured with the identical mobility group name and each controller must have the others listed as static mobility peers. This mutual peer configuration enables the controllers to authenticate each other and exchange client state during roaming events.

BIf WLCs with HA SSO are deployed, each WLC in the WLC HA pair considered separately as a

In an HA SSO pair, the standby WLC inherits the active controller's identity, so the pair counts as a single mobility group member - not two separate members.

CThe WLCs do not have to be of the same model or type to be a member of a mobility group,

While WLCs do not need to be the same model or type, they must still share the same mobility group name and virtual IP address, making this statement incomplete and misleading.

DA mobility groups does not require all WLCs in the group to use the same virtual IP address.

All WLCs in a mobility group must be configured with the same virtual IP address (typically 192.0.2.1) to allow proper mobility tunneling between controllers.
