During the installation of Avaya IP Office Server Edition, the root password is set for the underlying Linux operating system on which the Server Edition runs. This root password is critical for system-level access. Option C, "System," is correct because this root password also serves as the initial "System" password used for administrative access to the server’s core functions, such as via the Web Control interface or SSH for advanced troubleshooting. Option A (Administrator) typically refers to a higher-level application user (e.g., in Web Manager), which may have a different password. Option B (Manager) relates to the IP Office Manager application, which uses its own credentials, not the root password. Option D (Security) is a separate password used for configuration security settings within IP Office, not tied to the root password.References: Avaya IP Office Server Edition Installation and Maintenance Guide.
