Regarding the process of Mesh nodes going online on AC, which of the following descriptions is correct? (Multiple choice)

Question

Options

• AThe AP establishes a Mesh air interface link with an online Mesh neighbor, performs key
• BThe AP establishes a Mesh air interface link with an online Mesh neighbor, establishes a Mesh
• CThe AP establishes a Mesh air interface link with the online Mesh neighbor, performs key
• DAfter the AP is initially powered on, after the AC goes online to obtain the configuration, it will re-

• A
  74% (20)
• B
  11% (3)
• C
  15% (4)

Explanation

Options A and D are correct because they accurately capture two distinct phases of the Mesh node online process. In the first phase (A), the AP must first establish an air interface link with an already-online Mesh neighbor and then complete key negotiation before it can form a secure tunnel and register with the AC. In the second phase (D), after the AP successfully comes online with the AC and downloads its full configuration, it goes through a re-initialization of its Mesh connections using that configuration, which is an expected and necessary step in the process.

Option B is incorrect because it omits or misrepresents the key negotiation step, which is mandatory for securing the Mesh link before AC registration can proceed. Option C is incorrect because it likely presents the sequence out of order or attributes the link establishment to the wrong entity or stage, making the described process inaccurate even if individual steps sound familiar.

Memory tip: Think of the Mesh online process in two loops. The first loop is "Link, then Key, then AC" - the AP links to a neighbor, negotiates keys, and gets to the AC. The second loop is "Config triggers Re-connect" - once the AC pushes down the configuration, the AP re-establishes its Mesh relationships using that config. A covers loop one, D covers loop two.
