350-401 Practice Question: Which three statements about Cisco Wireless LAN…
Which three statements about Cisco Wireless LAN Controller (WLC) mobility groups are true? (Choose three.)
Answer choices
Why each option matters
Answer the question above first, then reveal the full breakdown to understand why each option is right or wrong.
Correct answer & explanation
✓
A mobility group can contain up to 24 controllers.
Mobility groups allow seamless client roaming across controllers, support up to 24 controllers per group, require symmetric mobility tunnels, and use a backup controller list for redundancy. They do not require all controllers to be in the same subnet or same hardware model.
Answer analysis
Option-by-option breakdown
For each option: why learners choose it and why it is or isn't the right answer here.
- ✗
Controllers in the same mobility group must be in the same IP subnet.
Why it's wrong here
Incorrect because mobility groups can span different subnets and even different geographic locations; they communicate via IP tunnels.
- ✓
A mobility group can contain up to 24 controllers.
Why this is correct
Correct because Cisco WLCs support a maximum of 24 controllers in a single mobility group.
- ✓
Mobility groups enable seamless client roaming between controllers without re-authentication.
Why this is correct
Correct because mobility groups allow clients to roam between controllers while maintaining their security context, avoiding full re-authentication.
- ✓
Mobility tunnels between controllers must be symmetric and use the same source and destination IP addresses.
Why this is correct
Correct because mobility tunnels are established using the management IP addresses of the controllers, and the tunnel endpoints must be reachable from both sides.
- ✗
All controllers in a mobility group must be the same hardware model.
Why it's wrong here
Incorrect because mobility groups can include different models of Cisco WLCs (e.g., 5508, 8540, virtual WLC) as long as they run compatible software versions.
