Which of the following are non-configurable service attributes?

Frame delay and frame loss are considered non-configurable service attributes because they are intrinsic to the performance and reliability of the Ethernet service rather than elements that can be adjusted or modified by a service provider or user. Frame delay refers to the time it takes for a data frame to traverse the network, while frame loss indicates the percentage of frames that failed to reach their destination. Both of these metrics are influenced by the underlying architecture and current load on the network but cannot be directly configured or set by end-users.

In contrast, attributes like bandwidth profile and service ability typically refer to parameters that can be configured to meet specific service requirements. For example, the bandwidth profile can be tailored to define how much bandwidth a service is allowed to use, while service ability addresses the potential capabilities offered to the customer based on the service level agreement (SLA). These are configurable aspects that can be modified to suit certain requirements or performance standards.
