A cloud administrator is deploying a new software-defined data center (SDDC) in VMware Cloud on AWS. Long-term planning indicates that a minimum of 30 hosts are required.
What is a valid management network CIDR based on the requirements?

What is a valid management network CIDR based on the requirements?
In a software-defined data center (SDDC) in VMware Cloud on AWS, the management network CIDR needs to accommodate a sufficient number of hosts and other network infrastructure. Given that a minimum of 30 hosts are required, a /20 CIDR block is the best choice as it accommodates up to 4096 addresses, providing ample space for current and future scaling needs. The other options, /23, /24, and even /16 either do not provide enough addresses or are unnecessarily large, respectively.
D /16 = 4091 hosts /20 = 251 hosts /23 = 27 hosts https://blogs.vmware.com/cloud/2019/10/03/selecting-ip-subnets-sddc/
Agreed with this answer, attaching the AWS official documentation: SDDC Deployment and Best Practices Guide on AWS https://docs.aws.amazon.com/whitepapers/latest/sddc-deployment-and-best-practices/account-requirements.html Section Infrastructure preparation and planning - Table 1 — Design considerations

Isn't it C? Based on: Reserved Address Ranges in SDDC Networks n 10.0.0.0/15 n 172.31.0.0/16 These ranges are reserved within the SDDC management subnet, but can be used in your on-premises networks or SDDC compute network segments.
D is correct
C A /16 is overkill, but 10.0.0.0/15 is one of the reserved IP ranges. Trick question.

D appears correct to me
