Which of the following is the MOST likely cause?

A cloud architect created a new delivery controller for a large VM farm to scale up according to organizational needs. The old and new delivery controllers now form a cluster.

However, the new delivery controller returns an error when entering the license code.

Which of the following is the MOST likely cause?
A . A firewall is blocking the port on the license server.
B . The existing license is for a lower version.
C . The existing license is not supported for clusters.
D . The existing license has expired.

Answer: C

Explanation:

Can’t be a firewall issue, or the old delivery controller would have a license error as well. Based on the information given, I would say they are not licensed for clustering.
