ITIL 4 Foundation Practice Exam

What defines a unique name used to identify and grant access rights to a user?

1. Profile

2. Identity

3. Username

4. Authorization

The correct answer is: Identity

The concept that defines a unique name used to identify and grant access rights to a user is known as an identity. In the context of ITIL and information security, an identity encompasses all the attributes that make an individual or entity distinguishable within a digital system, enabling them to access certain resources. An identity typically involves multiple components, including a username alongside various attributes that may describe the user’s role, permissions, or group memberships. This unique identifier ensures that access is managed efficiently and securely, allowing the system to recognize and authorize actions specific to that identity. While "username" may also seem to fit the description, it is a component of the wider concept of identity. A username alone does not encompass the complete notion of identity, which includes the permissions and rights associated with that username across the systems. Additionally, "authorization" relates to the permissions granted to the identity but does not define the identity itself. A "profile" generally refers to a collection of settings or characteristics for an individual user, but not to the unique identifying element. Thus, identity is the most fitting term in this context.
