Implementing and Configuring Cisco Identity Services Engine (SISE) — Question 109

An administrator is attempting to join a new node to the primary Cisco ISE node, but receives the error message "Node is Unreachable". What is causing this error?

Answer options

• A. The second node is a PAN node.
• B. No administrative certificate is available for the second node.
• C. The second node is in standalone mode.
• D. No admin privileges are available on the second node.

Correct answer: B

Explanation

The correct answer is B, as the absence of an administrative certificate on the second node prevents it from being recognized by the primary node. Option A is incorrect because the PAN designation does not inherently cause reachability issues. Option C is wrong since standalone mode does not affect the join process itself. Option D is not correct because lack of admin privileges would not directly result in the node being unreachable.
