A client device roams between wireless LAN controllers that are mobility peers, Both controllers have dynamic interface on the same client VLAN which type of roam is described?

Question

Options

• Aintra-VLAN
• Binter-controller
• Cintra-controller
• Dinter-subnet

• A
  5% (1)
• B
  90% (19)
• C
  5% (1)

Explanation

Wireless LAN Roaming Explanation

Option B (inter-controller) is correct because the client is moving between two separate wireless LAN controllers (WLCs) that are configured as mobility peers, which by definition makes this an inter-controller roam. Since both controllers share the same client VLAN/subnet, this is specifically a Layer 2 inter-controller roam, meaning the client retains its IP address throughout the transition.

Why the distractors are wrong:

• A (intra-VLAN) is not a standard Cisco roaming classification term - while the roam does occur within the same VLAN, this is not the correct terminology used to categorize controller-based roaming types.
• C (intra-controller) would apply if the client moved between access points managed by the same single controller, which is not the case here.
• D (inter-subnet) would apply if the client moved between controllers where each had the client on a different subnet/VLAN, requiring a Layer 3 roam - but both controllers here share the same VLAN.

Memory Tip: Use the prefix logic - "intra" = within (same controller), "inter" = between (different controllers). Since two controllers are involved, think "inter = two entities." The same-VLAN detail rules out inter-subnet, leaving inter-controller as the only fit.
