Explanation:
The root CA certifies other certification authorities to publish and manage certificates within the organization.
In a hierarchical trust model, also known as a tree, a root CA at the top provides all of the information. The
intermediate CAs are next in the hierarchy, and they trust only information provided by the root CA. The root CA
also trusts intermediate CAs that are in their level in the hierarchy and none that aren’t. This arrangement
allows a high level of control at all levels of the hierarchical tree. .
