Implementing and Operating Cisco Security Core Technologies (SCOR) — Question 201

An administrator is adding a new Cisco ISE node to an existing deployment. What must be done to ensure that the addition of the node will be successful when inputting the FQDN?

Answer options

• A. Change the IP address of the new Cisco ISE node to the same network as the others.
• B. Make the new Cisco ISE node a secondary PAN before registering it with the primary.
• C. Open port 8905 on the firewall between the Cisco ISE nodes.
• D. Add the DNS entry for the new Cisco ISE node into the DNS server.

Correct answer: D

Explanation

The correct answer is D because adding the DNS entry for the new node is crucial for name resolution in the network. Option A is incorrect as changing the IP address alone does not guarantee successful integration without the proper DNS entry. Option B is not necessary for the registration process; the node can be registered directly with the primary PAN. Option C is also incorrect because while port 8905 may be important for communication, the DNS entry is essential for initial identification and connectivity.
