What is the minimum size management CIDR block that is needed to meet this requirement?

An administrator is preparing to deploy a VMware Cloud on AWS software-defined data center (SDDC) and is planning to scale up to 48 nodes in the future.

What is the minimum size management CIDR block that is needed to meet this requirement?
A . /24
B . /16
C . /23
D . /20

Answer: D

Explanation:

The management CIDR must be one of 3 available sizes: /16, /20 or /23. The primary factor in selecting the size is the anticipated scalability of the SDDC. In single-AZ deployment, a /23 CIDR can support 27 ESXi hosts, while a /20 can support up to 251.
