How are mobility groups created, excluding mobility anchors?
To create a mobility group, each Wireless LAN Controller (WLC) must use the same mobility group name and be defined as a peer in each other's static mobility members list. This ensures that all controllers in the mobility group can communicate and manage client roaming seamlessly.
Answer A is correct To create a Mobility Group, you just add WLCs to the Mobility Group Member list (of each WLC). WLCs with the same Group Name will end up in the same Mobility Group. If you add WLCs with a different Group Name to the list, they will form a different Mobility Group, but end up in the same Mobility Domain. The Mobility Domain can contain up to 3 Mobility Groups.
The Group Name is inherited from the Default Mobility Domain Name
None of the answers a true but it seems like there is a mistake in the A answer. If you replace "domain" with "group" - that would be true.
Think A is correct but its not precise. According to Cisco book: mobility domain - A logical grouping of all mobility groups within an enterprise. So in theory the WLC can be on different mobility groups BUT on the same mobility domain. Hence, A is correct, however is not precise because to being called peers they should be on the same mobility group. Its the best answer of this 4 imo.
"Each WLC must use the same Mobility Domain name and be defined as a peer in each other’s Static Mobility Members list. The exception to this rule are when guest anchors are deployed where Cisco recommends deploying a separate Mobility Group for the guest anchors". Enterprise Mobility 8.5 Design Guide, Ch2, p2-57 If you go to WLC GUI and click the Controller tab you will see the Default Mobility Domain Name field. I think it's what is meant. If you check further this guide on the p 10-20 you will see the phrase "The "Group Name" in Figure 10-13 above is the name configured under the foreign WLC's 'Default Mobility Domain Name'". They mixed up 2 concepts in that guide and in the Official Cert Guide and they didn't write in the Official Cert Guide that to assign a WLC to mobility group you need to fill the Default Mobility Domain Name field.
So A is correct for sure
Answer A with the correction commented by others.
