HP Exam HPE0-V14 Topic 6 Question 6 Discussion

A customer has redundant SAN fabrics with a single HPE SN6000B 16 GB 48-port.24 SAN switch in each fabric. They plan to expand their virtualization environment by adding two HPE DL360s and an MSA 2042. Each DL360 will connect to the fabric via dual port 16 Gbps FC HBAs, and the MSA 2042 will connect with four FC Ports. The 24 ports on each switch are currently In use for other applications.

How many additional Port on demand licenses must be customer purchase for each switch if they redundantly connect all the new FC HBA ports to their existing SN600B switches?
