What is a role?

• A. Set of permission.
• B. A network device.
• C. A type of DNS record.
• D. An IP address pool.

Answer: (A)

A role is a collection of permissions that defines what actions a user or account is allowed to perform within a system. Instead of tying privileges to individual objects, a role groups the necessary capabilities (such as view, create, modify, delete, or administer) and can be assigned to users or groups to grant those capabilities in a controlled way. This approach supports least-privilege access, ensuring someone can do only what’s needed. In Infoblox, roles govern what a user can do in the DNS/DHCP/IPAM grid, shaping what objects can be accessed and what operations are permitted. For example, one role might allow full administration of networks and DHCP scopes, while another might permit only read access. The other options describe concrete entities (a network device, a type of DNS record, or an IP address pool) rather than a set of permissions, so they don’t capture the idea of a role.
