The goal is to grant a user permissions to configure a Virtual Private Cloud (VPC) while explicitly denying the ability to create subnets. This requires a combination of roles that provide configuration and visibility without granting network creation privileges.

Security Admin (A): In the context of a VPC, this role allows a user to configure security features such as distributed firewall (DFW) rules and security groups. Crucially, it does not grant permissions to create or manage subnets.

Security Operator (D) & Network Operator (E): These roles provide necessary read-only access to the VPC's security and network configurations, respectively. This allows the user to view the current state, which is essential for proper configuration, without granting modification rights to the core network infrastructure.

This combination adheres to the principle of least privilege by granting only the required permissions.

B. Network Admin: This role is incorrect because, within a VPC, it is specifically assigned the permission to create subnets and configure gateway networking, which violates the stated requirement.

C. VPC Admin: This role is incorrect as it is the highest-level administrative role for a VPC and includes full permissions to perform all tasks, including creating and managing subnets.

1. VMware NSX 4.1 Administration Guide

"Role-Based Access Control for a VPC".

Section: NSX User and Role Management > Role-Based Access Control for a VPC.

Content: This section explicitly defines the permissions for roles within a VPC. It states that the VPC Admin and Network Admin roles can create subnets. It also specifies that the Security Admin role is limited to configuring security groups and DFW rules

while Network Operator and Security Operator roles are read-only. This documentation directly supports that the combination of Security Admin

Network Operator

and Security Operator fulfills the question's requirements.
