In the Mest network, it is composed of multiple nodes (APs), each providing different functions. Which of the following descriptions about nodes is wrong?

Question

Options

• AMP provides Mesh services and has Portal functions
• BNeighbor MP is an MP or MPP that is in direct communication range with a Mesh node.
• CThe candidate MP is the neighbor MP with which the MP is preparing to establish a Mesh link
• DMPP is an MP node that connects Mesh networks and other types of networks

Explanation

Option C misdefines the candidate MP: a candidate MP is a neighbor MP that has been identified as suitable for mesh link establishment based on evaluation criteria (such as signal quality or link metrics) - it is not yet in the active phase of "preparing to establish" a link. A node may have multiple candidates but will only initiate peering with the best one(s), so conflating "candidate" with "preparing to establish" overstates the commitment level at that stage.

Options A, B, and D are all accurate: MP nodes do provide core mesh services (and certain MPs can incorporate portal-like functions within the mesh architecture); neighbor MP is correctly defined as any MP or MPP within direct wireless communication range; and MPP (Mesh Point Portal) is precisely the node type that bridges the mesh network to external, non-mesh network types such as wired Ethernet.

Memory tip: Think of mesh link progression as a pipeline - Neighbor → Candidate → Peer. A neighbor is anyone in range, a candidate is a shortlisted neighbor that meets selection criteria, and a peer is one you've actually linked with. Option C mistakes the "candidate" stage for the "peer-in-progress" stage, which is one step too far.
