In the WDS network, what is the name of the AP that is connected to the AC by wire?

Question

Options

• ALeaf AP
• BMiddle AP
• CMaster AP
• DRoot AP

• B
  13% (2)
• C
  7% (1)
• D
  80% (12)

Explanation

Option D is correct because in a WDS (Wireless Distribution System) network, the Root AP is the access point that has a wired connection to the Access Controller (AC), serving as the entry point between the wired and wireless portions of the network. All other APs in the WDS network communicate wirelessly, but the Root AP anchors the entire topology to the wired infrastructure.

Option A (Leaf AP) is wrong because Leaf APs sit at the edges of the WDS tree - they have no downstream APs and connect wirelessly back toward the root. Option B (Middle AP) is wrong because Middle APs relay traffic wirelessly between the Root AP and Leaf APs, with no wired uplink. Option C (Master AP) is a term more commonly associated with other wireless clustering or load-balancing contexts, not the specific role of wired AC connectivity in WDS.

Memory tip: Think of the Root AP like the root of a tree - it is where the tree meets the ground (the wired network). Everything else grows wirelessly from there.
