Which of the following are common types of user access levels in IT environments?

In IT environments, user access levels are critical for managing permissions and ensuring security. The correct answer highlights three distinct access levels: administrator, user, and guest.

Administrators typically have the highest level of access, allowing them to manage systems, configure settings, and perform maintenance tasks. They can add or remove users, change permissions, and oversee the overall functioning of the IT environment. This level of access is necessary for those responsible for maintaining the integrity and security of the system.

Users represent the general population of individuals who need to interact with the system, albeit with limited permissions. This allows them to perform everyday tasks without the authority to make significant changes or access sensitive administrative tools.

Guests, on the other hand, are granted minimal access, often restricted to viewing or using specific features of the system without the ability to modify data or settings. This tier is commonly used for temporary access, allowing external parties to use resources without compromising the security of the system.

The other options, while including terms that may overlap in function, do not accurately represent the typical structure and hierarchy of access levels found in most IT environments. For example, terms like "editor," "superuser," "owner," "manager," "viewer," and "moderator" imply specific roles
