Exam MCIA - Level 1 topic 1 question 79 discussion

An organization is sizing an Anypoint VPC to extend their internal network to CloudHub.
For this sizing calculation, the organization assumes 150 Mule applications will be deployed among three (3) production environments and will use CloudHub's default zero-downtime feature. Each Mule application is expected to be configured with two (2) CloudHub workers. This is expected to result in several Mule application deployments per hour.
What is the minimum number of IP addresses that should be configured for this VPC that results in the smallest usable private IP address range to support the deployment and zero downtime of these 150 Mule applications (not accounting for any future Mule applications)?
