Which of the following is NOT one of the user types supported in Nokia SR Linux?

Nokia SR Linux defines user types based on their management and access domain within the system's architecture. It officially distinguishes between "SR Linux users," who are managed by the Network Operating System (NOS) for access to the CLI and gNMI, and "Regular Linux OS users," who are managed by the underlying Linux kernel for shell access. The system also supports containerized applications, which have their own user contexts ("Container users"). "Remote users" is not a distinct user type; rather, it describes a connection method (e.g., via SSH) that can be used by any of the supported user types.

A. SR Linux users are a primary, supported user type managed by the SR Linux AAA services for access to the NOS functions.

B. Regular Linux OS users are a supported user type, managed by the underlying Linux system, providing access to the base OS shell.

C. Container users are supported through the system's architecture, which allows running third-party applications in containers with their own user spaces.

1. Nokia SR Linux R23.10 User Guide, Chapter: System management > User management > Users. The document explicitly states, "SR Linux supports two types of users: SR Linux users and Linux OS users." This confirms options A and B are valid user types and that the primary classification does not include "Remote users."

2. Nokia SR Linux Architecture White Paper (2020), Section: "A pristine Linux environment," Page 6. This paper details the architecture where the SR Linux NOS applications run on a standard Linux distribution. This separation is the basis for having distinct SR Linux and Linux OS user domains.

3. Nokia SR Linux R23.10 Extensibility Guide, Chapter: Third-party applications. This guide describes the support for running applications within Docker containers on the system. This functionality inherently means the system supports the existence and operation of users within those containerized environments, making "Container users" a valid concept.
