Which management category is not part of FCAPS framework?

Configuration management is the 'C' in FCAPS, responsible for provisioning and tracking network device configurations.

Security management is the 'S' in FCAPS, covering access control, auditing, and protection of network resources from unauthorized use.

Performance management is the 'P' in FCAPS, focused on monitoring and optimizing throughput, latency, and utilization metrics.

FCAPS is an ISO/ITU-T telecommunications management framework whose five categories are Fault, Configuration, Accounting, Performance, and Security management. Authentication is a mechanism used within Security management, not a standalone FCAPS category, so it is the correct answer to what is NOT part of FCAPS.

Fault management is the 'F' in FCAPS, responsible for detecting, isolating, and correcting abnormal network conditions.
