B. The frequency and lifespan of each application build:

Understanding how often builds occur and how long they need to be retained is crucial for sizing storage and compute resources. This information helps determine the I/O and storage requirements for the Nutanix environment.

D. The configuration/specs of the VMs within each application build:

Knowing the specifications of the VMs, such as CPU, memory, and storage requirements, is essential for accurately sizing the Nutanix cluster. This information ensures that the infrastructure can handle the workload generated by the CI/CD pipeline.
