vBond Port for Controller Certificates

D.

In a Cisco SD-WAN environment, vBond orchestrator is used for authentication and initial device discovery. vBond also maintains a centralized list of all available controllers and their IP addresses, which is essential for establishing secure overlay tunnels between SD-WAN devices.

By default, vBond uses TCP port 12346 for secure communication using TLS. However, it is possible to configure an alternate port for vBond communication during initial setup. If no alternate port is configured, then the default port of 12346 is used.

Now, coming to the question at hand, the options provided are: A. 12344 B. 12345 C. 12347 D. 12346

As discussed above, vBond uses port 12346 by default, and if no alternate port is configured, then this port is used. Therefore, the correct answer is D, i.e., 12346.

Option A, i.e., 12344 is incorrect as this is not a standard port used for vBond communication.

Option B, i.e., 12345 is also incorrect as this is the default port used by vManage for secure communication.

Option C, i.e., 12347 is not a standard port used for any SD-WAN controller communication.

Hence, the correct answer is D, i.e., 12346.
